Let us just have a glimpse of the past history! It was not back when we used to have those extremely complicated VCR systems in our house! It was the workhorse of the security industry. But let me tell you that there are still many VCRs out there working.

In this advanced world that is decked with the culture of all kinds of multiplexes, CD systems and home theaters, people still have VCR systems at their home. That is what I mean to say that this extremely cute VCR was given new life for a time with the advent of multiplexers, but now with the passage of time, it is losing its importance.

The greatest drawbacks that the VCR has to face with are the very poor frame capture rate, the problem of changing tapes, and the very time consuming playback issues. These are some of the very common drawbacks, not to mention the extreme ones. You can yourself understand! In the end, all I have to say is that
the VCR was a great tool for its time, but none of us who have changed really miss it.

Then came the DVR (digital video recorder). It is geared up with loads of added advantage as compared to VCR! They are 4, 8, 9, 16, or 32 channel units that provide individual frame rates, individual quality settings, motion recording, extremely high and accurate search/playback, easy remote viewing, as well as advanced and width requirements.

The DVR is no doubt the workhorse of the industry today. And ;let me now tell you something about the NVR (network video recorder) which is the IP version of the DVR. It holds the same specifications as that of DVR, but is designed to handle IP (Internet protocol/network) cameras only.

And last but not the least the HVR (hybrid video recorder) that is just perfect in the case when regular analog (not IP) cameras are in place. They also play a great role when one wants to migrate to IP cameras and eventually have a NVR system.
