What is a BNC connector used for?

BNC connectors are the core connector types used to connect coaxial cables between the security cameras and the security DVR.  Most commonly RG59 coaxial cable is use to transmit the video signals from the security cameras back to the DVR.  Both security cameras and security DVR’s have integrated female BNC connectors on them that are used to attach the coaxial cable to them.  Once a BNC connector is terminated on both ends of the RG59 coaxial cable, you are then able to plug the cable directly into the cameras and DVR.  The BNC connector uses a locking mechanism that creates a strong long-lasting connection.   BNC connectors are very commonly used in most radio, television, video, and CCTV applications.

Types of BNC connectors:

There are BNC connectors available for almost every coaxial cable type.   Some of the most popular coaxial cables used today are RG6, RG11, and RG59 coaxial cable in plenum and non-plenum forms.  In the CCTV world, the BNC connectors for plenum and non-plenum RG59 coaxial cables are by far the most common.   Non-plenum cables are standard cables with a PVC jacket, and are used for installations in homes and riser buildings.  Plenum rated cables have a unique jacket that includes a special compound for protecting the cable from burning fast and putting harmful toxins in the air.  Using plenum rated cables and BNC connectors is mandatory in installations where cables are installed in an open-air plenum ventilation system.  Plenum environments are often found in high-rise commercial business installations.  It is always recommended to follow your local building codes and use the right connectors and cables that support them.

The key is to always use the BNC connector that is designed for the coaxial cable type you are using in your installation.  BNC connectors are designed to support the terminations on different coaxial cable types and jacket types.  If you do not have the right BNC connector for your cable type, then the connection will only fail.  Which means your security cameras will no longer transmit video, and your system will no longer be securing your home or business.

Compression or Crimp BNC connectors:

The two most common styles of BNC connectors are compression and crimp types.   Compression and crimp explains the actual mechanism for terminating the BNC onto the cable.   Crimp style BNC connectors are terminated by crushing the connectors sleeve onto the cable.  By deforming the metal of the connector you are forcing it to crush around the cable.  Crimp BNC connectors are really “old school” types, and really do not protect the terminations or create a long lasting termination.   Today, most installers have moved to using more modern compression style BNC connectors.  Compression BNC connectors use an actual 360 degree clamp to attach to the coaxial cable.  By clamping to the cable the termination is protected from possible dust and moisture from penetrating the connection.  Plus compression BNC connectors provide up to 60 pounds of pull force, which will ensure a longer lasting connection.   Although compression BNC connectors come with an extra cost, they will ensure your connections are stronger, last longer, and perform much better.

Keys to buying BNC connectors:

The best way to ensure your installation is successful is to buy the BNC connector that supports your cable type.  Once you have chosen your cable type, then it is easy to choose the BNC connectors you need.  If you are using compression BNC connectors than you need to make sure you have a coaxial cable stripper to prepare your cable correctly, and a compression tool to terminate the connectors.  If you are using crimp BNC connector then you will still need a cable stripper, but you will have to make sure you get a crimping tool that works with your cable type.  The coaxial cable type you buy should clearly document the type and gauge characteristics of the cable.  This documentation should be clearly written on the box of the cable, and the cables jacket.  So just make sure you match the connector type with the cable type.

Most BNC connector manufacturers also make the cable strippers and tools you need to terminate their connectors.  So buying BNC connectors, strippers, and termination tools within the same brand has its benefits.  This often ensures that they all work together.  Not all termination tools work with all brands of connectors.  So it is important to use the parts that will collaborate together to provide fast, easy, long-lasting terminations.

Although BNC connectors are a small part of a CCTV installation, they play an important role in ensuring your system performs.  Choosing the right connectors and buying the right tools to install them will ensure your installation is done properly.  The last thing you want is your BNC connectors hindering your home and business from being secured properly.  Do your research and buy right the first time!

The purpose of a CCTV monitor is to attach it to a security DVR which allows the video that the system is capturing to be viewed.  Usually this video is either live video or recorded video that was stored in the past.  Most commonly the connection between the DVR and the monitor is made using a BNC cable, VGA cable, or HDMI cable.  Once the monitor is in place you can use it to view video or view the menu of the DVR’s software.  Since many of the connections of a computer monitor and CCTV monitor match, many people decide to save money and just connect a computer monitor to their security DVR.   But in the end the question is does this really help or hurt the CCTV systems performance?

CCTV Monitors at CablingPlus.com

One of the major differences between a computer monitor and a CCTV monitor is the resolution.  The video resolution of a CCTV monitor is usually much higher.  The purpose of this is to allow you to watch the surveillance video at the same or higher resolution it is being recorded at.  So if you invested in high resolution security cameras, you will never get the quality video they are providing for on a computer monitor.    So you will see less detail and less clarity in your video.   This really defeats the purpose of buying the highest quality security cameras, which means you are missing out on your systems capabilities.

The biggest difference between a computer monitor and a CCTV monitor would be the purpose and durability.  A CCTV monitor is designed to be on and working 24 hours a day year around.   The CCTV monitor is always on for security guards, home owners, and business owners to monitor 24/7 video.  A computer monitor would simply burn out if you tried to keep it on at all times.  Computer monitors are meant to be on for a short amount of time in the day, and the computer often puts them to sleep when you are not actually working on the computer.  The reality is that you could burn through a few computer monitors in the amount of time it would take you to   burn through just one CCTV monitor.

The cost of CCTV monitors has gone down dramatically over the past 5 years.  It used to be thought that adding one to your surveillance system would create unaffordable costs.    But today CCTV manufacturers have been able to drive cost down while ensuring that consumers get the high resolution monitors that are built to last.  The best way to ensure your surveillance system performs to its highest potential is to always use the right monitor for the job!

The bullet camera has become the hottest and most popular security camera type for many home owners.  A bullet camera is a cylinder bullet shaped camera that gives you the mounting flexibility to really install it anywhere. As long as you have a small amount of flat surface you can put a bullet camera at almost any location. Once mounted you can then simply aim the bullet camera towards any direction to secure the area you are most concerned about. Since a bullet camera includes a weatherproof and vandal proof housing, you can rest assure it is 100% protected from even the most extreme weather conditions.   Besides the external shell the bullet camera also provides an unprecedented intimidation factor.  The mere presence of a bullet camera shows possible intruders that you take security serious and that your perimeter is secured!

Bullet Cameras at CablingPlus.com

Bullet cameras come in all different types.  There are some with infrared LED’s that allow you to see in total darkness, and there are some that have adjustable lenses so you can manipulate the camera to better view an area.  The infrared LED’s allow the camera to capture high quality video in total darkness.  So if there are areas where you are concerned about the lighting conditions, the infrared bullet camera will solve your problem. The camera will record in color during the day, but at night it will create its own light and change to black and white while continuing to provide high quality video.  The infrared LED’s will sense the lighting conditions are poor, and create the light needed to ensure the camera always performs.  The lens is also an important part of a bullet camera.  Most bullet cameras come with either a fixed or Varifocal lens.  The fixed lens is a basic lens that is set to a particular focal length.  So once you plug the camera in what you see is what you get.  But a Varifocal lens gives you a small lever where you can adjust the focal length of the lens to better capture an area.  Although the Varifocal lens camera is best, they do come with additional cost.  Most installations consist of a mixture of both Varifocal and fixed lens bullet cameras, so you can use the cameras with the varifocal lenses in the areas that are larger or more challenging to secure.

At the end of the day there are numerous security camera types that can be used for different needs, features, and applications.  The bullet camera just seems to be the popular choice for most home owners today.  Besides the standard features they just look the most aesthetically pleasing when mounted on the side of the house.  Plus their ease of installation makes them ideal for home owners and do-it-yourselfers that have the desire to quickly secure their homes and property.

Understanding the connections of bullet cameras:

A bullet camera has two connections coming out the back that are used for both power and video.  The first connection is the power plug.  This is where you must connect the power source into the camera.  Most bullet cameras will take 12 VDC or 24 VAC power.  And many of them will take both which is why they are called dual voltage.   The power connection is where you will attach the cable coming from your power source to camera.  Most people use a multi-conductor cable for this purpose.  The multi-conductor cable will attach to the camera on one end, while the other end is attached to a multi-camera power supply or individual power transformer.  Powering a bullet camera is easy and is really a plug and play installation.

The second connection coming out of a bullet camera is used for video.  It is a small cable that has a female BNC connector on it so you can run the coaxial cable between the camera and the Security DVR you use to capture video.  The video connections are made using BNC connectors on both ends of your coaxial cable.

1. Anything a person does in the privacy of their own home is private. Right?  Well, not quite.  If your household activities are observable from a public area, then according to the law, you have no expectation of privacy.  What this means is that anyone with an outdoor security camera, can record your household activities if you don’t draw your shades or close the door.
2. Why use nine outdoor cameras when two will do the job?  With today’s megapixel security cameras, you can use motion detection and zoom capabilities to cover the same area with twos cameras that would take nine standard cameras.  Be prepared to pay the price though.  These megapixel cameras are still on the expensive side.
3. Like your camera security surveillance systems in living high definition?  2011 is the year that some major camera suppliers begin shipping HDcctv cameras.  The level of detail is extraordinary and demand is expected to be high.  If you have a security system with cameras and you want to be a high tech trend-setter in your neighborhood, then an HDcctv camera is the way to go.
4. Not all camera DVR systems are the same quality.  Take the analogy of cars.  Any car can take you from home to work, but that is where the similarities end.  There is a world of difference between a $900 used Hyundai and a brand spanking new $75,000 Corvette.  The same is true with a DVR camera security system.  Reliability is the key. The best DVR security system will do the job of recording your outdoor security footage for a long time.  The second most important quality of a DVR home security is its storage capacity, especially if you decide to go with an HDcctv camera.
5. Yes, you can see in color at night. 2011 is the year that low light cameras make their come-back.  After years in the backseat to night vision IR cameras, low light cameras are coming back, and this time these low lux security cameras are equipped with in color recording capabilities.  Technology improvements have allowed near complete dark be no problem for these new cameras to see in living color.  One of the companies leading the charge is Axis Communications.
6. Software that does it all.  The applications available for outdoor security cameras, and surveillance cameras in general have increased exponentially.  Most of these applications have been developed for the commercial side of the business, but some have trickled down to the homeowner side.  Here are just three samples of what software can do for you.

QSEE Fake Security Camera

When using fake security cameras, the number one rule is to remember that it should only be used as an addition to an existing system.  Prices have really come down on camera surveillance systems in the last couple of years and the quality is better than ever, not to mention the fact that the systems now integrate easily with home networks.   So, start with at least two real cameras and then you can add a decoy camera to the mix.  Next, make sure that the camera fits in well with the rest of the cameras in your system.  By that, I mean make sure that the fake looks like other cameras in the system.  If all of your other cameras have LED lights, then make sure that your fake has them too.  You do not want to give criminals any reason to suspect that a dummy camera is on the property and giving all of the cameras in the mix a uniform look is one way to accomplish that.  Make sure that the camera is in a logical and observable position.  A camera that sticks out like a sore thumb might be a clue that it is a fake.  On the other hand, don’t hide the camera as if it were meant to record spy camera videos.  The camera’s purpose is advertising and you do want intruders to know that it is there.  Lastly, tell as few people as possible that you are installing fake security cameras.  Information has a way of getting around and you certainly do not want the fact that you are using fakes to get around. Following these smart tips will go a long way to maximizing the protection afforded by fake security cameras.

Everyone has tight budgets these days and some people might be inclined to buy a system on-line and install it themselves. Surveillance camera installation is easier than ever before.  Yet, because of all of the options and choices available, it is more intricate than it used to be. Proper set-up is the only way to ensure the optimum function of any system. If you really need to save money, then you can designate some of your cameras to be fake security cameras. When you factor in CCTV wireless systems and the need to provide 100% protection over a given area, the need for a professional installation becomes evident. Many insurance companies will provide premium breaks for companies or homes with monitoring equipment, but if the system is improperly installed and a burglary occurs, insurance adjusters can refuse compensation.

CCTV camera installation can be especially tricky. The system is of course on a closed circuit, but this requires a higher level of sophisticated installation. All the cameras must be calibrated, focused and maintained to ensure security. A system that is shoddily installed can not only lead to breakdowns, but corrupted playback evidence as well. Again, adjusters will examine the system to see if the fault lies with owner.

There is also the deterrent factor of a professionally installed system. A would-be burglar will investigate a potential business or home and gauge the level of security. The professional thief will be as well versed on security systems as anyone in the business. Should they spot a system that is obviously put in by an amateur, they know how to find the weak spots and take advantage of any sup-par installation. However, if he sees a system that is installed using top-notch techniques and equipment, he will more than likely move on to find a system that is easier to crack.

Perhaps the most important aspect of a professional security camera installation is the peace of mind that comes with a system that is done by an expert. The company that installs it will stand behind their work. With regular maintenance and check-ups by the installer, a camera system will last for many years, giving the buyer an investment that more than pays for itself.

Professionally installed outdoor CCTV security cameras will deter most criminal elements. In the same way that a dog will scare off someone intent on home-invasion, the simple appearance of a camera will be enough incentive for the thief to look for easier places to break into. An impressive CCTV camera housing that is imposing will let anyone intent on theft know that this business takes security seriously.   An independent market data analyst company, Datamonitor claims that the shrinkage problem is huge, with totals in the billions of dollars per year.  On the inside of your business, you need to be a little more subtle.  A discretely placed bullet CCTV camera may help if you a having a shrinkage problem, without a big impact on employee moral.

Depending on the area to be covered by the CCTV security equipment, the business should determine whether the live CCTV cameras should be fixed or rotating. A day night CCTV camera that pans back and forth might be needed for a parking lot, while a principal back door would require a fixed IR CCTV camera for 24 hour coverage. Businesses that are concerned with employee theft might consider two fixed cameras on every egress to ensure total visual coverage. Using a dome CCTV camera is always an advantage because they keep people guessing as to which way they are pointing.  In fact, a dome camera with two cameras could have 360 degree coverage.  The benefit of two cameras in different locations on an exit is that it will give the company a 3 dimensional view of everyone entering and exiting the premises. These types of videos can be invaluable in catching bulky jackets and abnormal behavior.

Wireless CCTV systems are becoming the favorite for companies that either have a lot of area to cover or need to keep tabs on different parts of the company at different times.  Wireless cameras are harder to compromise. The signals are sent directly to the control center, so there are no cables that could be cut or disabled. IP CCTV cameras offer even more wireless advantages as their signal can be fed directly into the security computer network.  Versatility is the biggest benefit of wireless technology. These cameras can be small and unnoticeable, or blatant and intimidating, dcepending on the situation.

In today’s economy there are people, both outsiders and employees, who will try to take advantage of any weakness in a company.  The use of a CCTV camera surveillance system can be the best insurance that any company can buy.  For the financially minded business owners, you can show that a CCTV camera security system has an ROI.  Just measure your shrinkage levels before and after the install of these cameras.  In 99% of the cases, you will find that the CCTV security surveillance system is a valuable asset of the company.   Additionally, it will most likely prevent break-ins and theft.  That is what I call, “peace of mind.”

No matter what you are looking to protect or investigate, a camera surveillance system can help do the job. Whether it is home or business protection and monitoring or investigative work you need done, camera surveillance systems provide the visual proof needed to prosecute criminals or uncover a mystery.  Also, their mere presences is a factor in reducing crimes around the cameras. In order for this to be true; 1) The criminal must be aware of the cameras and 2) the perceived risk presented by the cameras must be greater than any reward of the criminal activity.  The only reason to hide the cameras is if you need to catch someone in the act of wrongdoing.  In that case a hidden camera is required.

Wireless camera surveillance allows you to install a camera anywhere you need to monitor.  It allows the cameras be be more easily hidden, if you want to go that route.  When you compare home security systems, make sure that you know if you want hidden cameras.  It make a huge difference in the type of cameras you need, and their price.  Keeping an eye on a new babysitter or nanny is easy with a wireless hidden spy camera as part of your system. Ensuring an elderly loved one or is being properly cared for and treated well while you are away from is easy when the wireless surveillance system is in place. Recording and monitoring your home is an easy way to make sure caretakers are responsible, trustworthy and attentive to their charges. Easy to use, there are no wires to worry about and no extensive knowledge about cameras or electronics is needed to install a wireless camera. The small unit size makes using these wireless spy cameras easy and discreet.  You can even buy spy cams pre-installed in common household items such as clocks and books.

Keeping a watchful eye on your home or business is a smart way to stay safe.  A night vision security camera installation can be useful for monitoring driveways, garages, parking lots and loading docks, and to keep track of visitors and employees as they come and go. Home security system installation plans should always include entrance doorways or other entries.  It is a wonderful way to see who is visiting, making deliveries or soliciting business so you can decide for whom and when to answer the door at your discretion.

Do not be afraid to ask experts for help, they will be happy to guide you in the right direction and help make choosing your system easy and stress free.

Basic Terms in Night Vision Security Cameras

Almost all the cameras available today are digital in nature, which means that they record and work in a format compatible with computer systems. Therefore, a night vision security camera is also called a night vision digital camera. Just like other recording and video devices, these cameras will use a compression algorithm to record the video the latest of compression standards is MPEG-4. A camera with MPEG-4 will record more hours of footage per Gigabyte of memory occupied than the one using MPEG-3 compression standard.

Night vision cameras see in the night by working in the infrared part of the light spectrum. Put simply, they do not work with the type of light we use to see objects rather they detect and work with light that has a different wavelength. This is the reason that the footage captured by these infrared security cameras is different from our normal vision; the color red will not be detected as red by night vision cameras, for example. Though the cameras themselves do not work in the same light spectrum, using post-processing in computer, the footage captured can be enhanced so that we can recognize the objects captured. Post processing also comes handy when we use it to detect motion in the captured footage. The computer can go over the footage, and show us only those parts wherein it detects motion. This saves a lot of time for human agent.

Wireless Night Vision Cameras

One of the latest advancements in day night camera is the availability of wireless night vision camera. These cameras will communicate with their receiver system wirelessly, usually using Wi-Fi. You should go for wireless if you do not want to be hassles with installing a system with wires on your premises. For example, if yours is an event management company that has to move around a lot, it would be a tough nut to crack having to install wired systems in temporary venues.

Because of how humans retire during the night, the security requirements of any office or home only increase during that time. By selecting the right camera as outlined in this guide, you will make sure that rather than stress about the security of your establishment, you can actually get a good night sleep as the night vision security camera works silently during the night.

A growing trend in crime deterrence is the use of dummy security cameras. Crime is a serious concern for many, but complete surveillance systems are complicated and expensive. Fake security cameras are a viable option for most people and small businesses, regardless of their security needs and financial means.

Dummy CCTV cameras are more common than many people realize. They have been shown to be a successful method for deterring criminal activity including vandalism and theft. A real surveillance system can be prohibitively expensive for a small business or private landowner. However, most fake security cameras cost between thirty and fifty dollars and are virtually indistinguishable from the real thing once mounted on the wall or ceiling.

There are a wide variety of models for every need. Dummy security cameras can be found in both indoor and outdoor styles. One popular and inexpensive model is the dome ceiling camera. This type of camera is usually seen in retail stores or other public locations, and is a great choice for a shopkeeper who needs a little extra security.

Another popular style is the outdoor model. These dummy surveillance cameras are often seen in parking lots or recreation areas as protection against car theft and vandalism. They have a thicker casing that in a real camera would protect the delicate interior from the elements. Of course, in the dummy security cameras this is all part of the illusion. These models are ideal for frightening off would be vandals around the home.

A slightly unusual variety of fake security cameras is the fake wildlife camera. A wildlife camera is typically mounted on a tree and is motion triggered so that it takes an infrared picture when something passes by. They are designed to help hunters track game patterns. The false version usually has a small LED light to attract the attention of people, and is used to deter poachers and trespassers on private land.

Most dummy CCTV cameras can be found with LED lights to increase their believability. These lights are powered by a battery and last a long time. They are designed to simulate a power button, making the fake security cameras even more indistinguishable from the real thing.

Since the goal of most protection and surveillance methods is to stop crime before it starts, often the illusion of a security system is more important than actually having one. After all, not many people want to be caught on film while committing a crime. The use of dummy security cameras can help create this illusion, and add an affordable extra layer of security to any property.
