CVBS or Composite Video Blanking and Sync is the conventional analog signal delivered through an analog BNC connector. In English, that basically means a pair of wires can transmit video and power from the camera to the recorder producing video surveillance. This was the first kind of technology introduced into the security industry, and it is still going strong today. When it comes to analog types, there are really two types that you want to keep in mind. CVBS and HD-TVI. Think of CVBS being like Windows 7. Everyone who has ever owned a computer was most likely using it since it was basically the only operating system out there. This means developers and integrators only developed their software and products for this one specific platform. Think of HD-TVI as Apple’s macOS. Mac is newer, cleaner, and more user-friendly (in some people’s opinion), but since Windows 7 is the most adopted software in the world, Mac users will suffer from not all of their products being compatible. This is exactly how it works in the security industry. CVBS has been adopted and used for so long now if you try to match 2 different CVBS brands together, there is almost 99.9% it is going to work. Whereas HD-TVI, there is a good chance it will work, but only if the devices have been developed specifically for HD-TVI and not the standard CVBS.
What is Pentabrid Technology
Pentabrid DVRs house 5 different technology solutions, HDTVI, HDCVI, AHD, Analog, and IP Network Technology. Pentabrids offer flexibility to integrators and installers, with Pentabrid DVR security professionals, who can have a product that capable of solving multiple problems that they may be faced with. Pentabrid DVRs are a great solution generator that would be great for any security professional to add to their product catalog.
HD-TVI stands for High Definition Transport Video Interface
TVI stands for Transport Video Interface and is the latest technology in HD analog transmission. It offers the same plug-and-play ease of install associated with a standard definition analog system, but is capable of delivering up to 1080p (2.1 megapixels) resolution images.
We recommend this for businesses that have existing equipment, as you do not have to do re-cabling. So, for security camera purposes you do not have to change out your old coaxial cables, just the camera, and receiver system to get 1080P minimum sharpness and clarity (up to 5MP).
CVI or Composite Video Interface
This is a brand-new technology in the security camera industry that provides a different method of transmitting video signals over coaxial cables. Until this new technology surfaced, analog CCTV video was limited to 960h video resolution.
AHD or Analog High Definition closed circuit
AHD stands for Analog High Definition. AHD is an analog closed-circuit television video surveillance standard of high definition 720P video, which allows the camera to send an HD signal over a standard coax or RCA cable. Echo Master’s AHD cameras offer a resolution of 720p standard HD versus CVBS cameras, which only offer a resolution of 480p, resulting in crisper, clearer details compared to traditional vehicle safety cameras.

Upgrading From Analog to IP
If you’ve already decided that you’re going to make the move from analog straight to IP, there’s still something else to consider. While Hybrids can be used with IP cameras on all channels, they won’t be able to do it in real-time like the Pentabrid can. If you need/want real-time recording, the Pentabrid is the obvious choice. Hybrids do a maximum of 7fps at 1080p and 15fps at 720p. They will do a full 30fps at D1, but that sort of defeats the purpose of having IP cameras if you can’t utilize their high definition resolution.
