I finally saw the end. I really saw the analog camera hanging in
there after the emergence of IP high definition cameras as a very
low-cost primitive video security solution. No more, as I now see the
1080p resolution HD-CVI cameras connected with cost lowering every week
will ultimately cause the poor quality video we still see today to
disappear. Finally a chance to rid ourselves of the bad video being
recorded every day, many times for naught as the quality of video is
useless in many cases. I was recently able to deploy HD-CVI, HD Over
Coax, in several locations and clearly saw the video quality as equal to
the high resolution IP I had been deploying. Wow, just connect the
exiting coax cable to the BNC connection and connect the HD-DVR and
boom, bad video to brilliant 1080p video with WDR. Four times the
resolution and 30% more coverage demonstrated that this technology is
every bit as good as the IP Video Security technology we see today.
I was not an advocate of HD over Coax until recently. With the quality of video coming from the new IP cameras, my recommendation was to replace the coax cabling and replace with Cat-5 for IP cameras. I saw customers looking at the high cost of the IP cameras as well as the cost of local security companies charging $100 /hour labor to replace the cable. I heard of issues in the early days (2013) of HD over Coax, and more importantly IP Cameras were making great gains in video quality and price levels. But HD-CVI has certainly gotten the IP folks on the defensive, but the performance over costs equation favoring HD Over Coax cannot be denied.
The benefit of HD-CVI is utilizing the same cabling that currently low resolution analog cameras are connected to and achieving the same benefits of IP cameras with high resolution and detailed video many times 4x the resolution/quality of the old analog cameras. The quality of HD-CVI is outstanding and the coax cabling allows two-way communication with the camera allowing detailed setup with each camera along with PTZ control and two-way audio.
Replacement of an analog camera with a HD-CVI camera takes approximately 10 minutes per camera. The replacement of the old DVR with a new HD-DVR takes approximately 30 minutes to setup. No connections are changed and the new system will offer remote access through the iPhone, Droid, or iPad offering high definition from any device.
Latency issues with IP camera systems are common today. The delay is typically in the live view of the camera coming from the NVR unit and this delay is seen and an issue with security guard monitoring, or critical sire monitoring. In most applications it is not an issue, however in a realtime environment, a delay of 2-3 seconds is critical. There are many IP systems in production today that "dummy down" the system to overcome this lag issue by lowering resolution, framework, etc.. HD-CVI does not experience any lag issues and provides the same quality video.
IP Cameras are an excellent choice in any CCTV Security Video system today. The lagging issues are something to consider and overcome with live feeds and other monitoring integration options. The quality of video and the choice of IP cameras make them "The choice" in any New Installation. However, my recommendation to owners of existing analog camera systems is to strongly consider replacing them with the new HD-CVI technology. With resolutions of 3 megapixel 1080p and the low cost of replacement, today you can get HD-CVI 1080 resolution at half the cost of an IP system, consider the HD-CVI system when you are ready to upgrade.
