Video Security & Surveillance in the Cloud
. . .and then along came Internet Video Recording . . .
Can you remember when your favorite TV programs were recorded onto a VCR? One show, one channel, one time slot ... one at a time. If you wanted to record two shows at the same you needed a second VCR. And all of that is assuming you could remember how to program the VCR to start and stop correctly and you had enough tape remaining on your VHS cassette .... because you never had a spare! And then along came the DVR and voila, you could record multiple shows at the same time, on different channels. No tapes or complicated setup necessary.
An exponential shift occurred in the video security and surveillance market. just like the VCR in your home, for many years businesses had to rely on VCR's to record and playback video. And believe it or not, VCR's continue to be deployed today .... go figure. When digital recording was introduced it changed the video landscape forever. This "new" technology allowed you to connect and record 4, 8, 16 or 32 cameras onto a single unit at the same time. The hard drive on the DVR was the critical piece. It was also the weakest link. Combining analog cameras with a digital recording platform remains a very popular, some may say "old school" method of recording video.
Video recording was upgraded again with the release of the NVR (Network Video Recorder). The main difference between a DVR and a NVR is that a DVR uses analog cameras, and a NVR utilizes IP based cameras. Actually it is the IP cameras that provide enhanced video imaging.
