Benefits of CCTV Surveillance
Long History of Implementation
The first CCTV system was installed in the 1940’s, and the technology has played a key role in the security industry since around 1970. With an analog CCTV system, you know exactly what you are getting because the technology has already been pushed and mastered. We know its advantages and its limitations, which makes it easy to determine whether a particular application is suitable for a CCTV solution, and what equipment is required.
Lowest Cost Solution
CCTV cameras and DVRs are normally priced lower than network cameras and IP video equipment. Of course, there are other factors to weigh besides initial cost when choosing between analog and IP. Still, depending on the specific needs of your application, a low-cost analog solution might just do the trick and could save you some up-front costs.
Large Selection of Products Available
Analog CCTV cameras come in a broad range of models to meet virtually any surveillance situation. Available offerings run the gamut from covert spy cameras to industrial PTZ domes. No matter how demanding or obscure your video surveillance requirements, odds are someone else has already used CCTV to meet similar needs, so a solution likely exists.
While the ground rules are still being laid out for compatibility amongst IP video products, in the world of CCTV, most products can live in harmony even when a variety of manufacturers are involved. This makes it easy to pick and choose analog cameras and surveillance equipment from different brands, and also incorporate new equipment into existing CCTV systems.
Because the benefits of IP video surveillance are almost too tempting to resist, many analog users are now turning to hybrid systems. With a hybrid analog/IP system, you can ease your way into the IP video world while still using much of your existing analog equipment. In fact, it’s quite easy to incorporate those old analog cameras into your new digital system. By using video encoders (also know as video servers) and hybrid DVRs, it’s possible to integrate analog CCTV cameras into an IP video solution.
Here’s how it works. The video encoder connects to the camera via coaxial cable. It then converts the analog video signals to digital and streams them over an IP network so they can be accessed in the same was as your IP cameras.
By using video encoders, you can reap the benefits of IP video without giving up on your existing surveillance equipment.
