Recently, I wrote 2 articles questioning what the future of analog hi-def video security (pt. 1 HD-CVI and pt. 2 HD-TVI) is or will be. And like part 2, I wasn’t planning on a part 3 or continuing this as a series. But, the speed and enormity of how hi-def analog CCTV keeps growing and changing (and it ain’t over), I felt it was too important NOT to write about. So now I will explain what HD-CVI 3.0 is, why its important and if it is the future.
Dahua Technology HD-CVI 3.0 DVRs and Cameras
Dahua’s HD-CVI has continued the development of patented core technologies that dates back to its launch in 2012-13. Most recently, the big news there is HD-CVI 3.0 which was released overseas in June 2016. This is the next/latest-generation analog hi-def video surveillance solution. HD-CVI 3.0 delivers true end-to-end hi-def video over existing coax systems and, among other things, is the first technology that realizes Pentabrid (5-in-1) XVRs and 4MP resolution over coax cable.
The new Pentabrid XVR series recorders feature compatibility for the five most popular CCTV standards: IP, HD-CVI, analog, AHD, and HD-TVI. Before HD-CVI 3.0, once a standard was chosen (analog, CVI, etc), the customer was committed to using that throughout the entire system. If you were upgrading an older system and keeping existing cameras, you had to stay with that format.
Now, Pentabrid XVRs offers customers more flexibility and choices when adding or replacing system components. For example, if you have older analog cameras that you want to keep, you have the option to add IP and AHD cameras, if you want. Now you can mix and match formats on the same XVR.
HD-CVI 3.0 4MP Cameras and DVRs
Also under the 3.0 umbrella are 4MP Tribrid DVRs. These DVRs can handle 3 CCTV formats (hence the term “tri”): 4MP HD-CVI cameras, Network IP cameras (up to 5MP) and analog cameras or can be setup strictly as a Network IP NVR. Very versatile and exciting.
Other big news came in the fall of 2016 with the announcement of 4MP HD-CVI cameras. Now, the last several weeks (Spring/Summer 2017) have seen the release in the U.S. of many different camera models. These include indoor/outdoor IR dome and bullet cameras with 2.8mm, 3.6mm and 2.8-12mm motorized zoom lenses for example.
Now, more than ever, customers are able to obtain hi-def video security for home and business over a much simpler wiring and setup architecture and at a much lower cost. If you are still using an old, outdated analog system, now is the time to upgrade to hi-def.
HD-CVI 3.0 Competes with IP Systems in Resolution and Features
Now, 4MP HD-CVI 3.0 systems, DVRs and Cameras are finally competing with Network IP systems in resolution, features and functions. Before 3.0, IP systems ruled supreme and will always be preferred by some installers, re-sellers and DIYers. But, the fact that 3.0 can be installed over existing coax (huge cost savings), is less expensive than most IP, doesn’t have the possible tech issues and now records and plays back in 4MP just like IP, it’s easy to see how and why HD-CVI 3.0 is so attractive.
Below are just few of the features found in HD-CVI 3.0 recorders that are normally only found in IP systems.
Intelligence. Facial recognition, people counting, heat map, smart tracking, smart scene adaption, intrusion, virtual tripwire, missing object, abandoned object, scene change, defogging and a voltage overload alarm are included.
Simplicity. The same simplicity and ease of installation as older analog systems, low-cost and easy-to-build and power can be supplied over coax cable.
Transmission distance. Compared to older analog systems, cable can be extended as far as 4,000 ft. by using 75-5 cable.
No-latency. Outstanding real-time performance, no compression processing required, vivid image quality.
Smart H.264+ codec. Savings of up to 70% bandwidth and storage, systems can retain more information for longer periods of time without sacrificing image quality.
Cable infrastructure. Real simple: you can use the same quality coax cable you already have in place to upgrade to hi-def.
So, is THIS the future of analog CCTV? Right now, it looks like it is.
