Digital video recorders and network video recorders come in various different models and types. Understanding what to look for is important and even more important is understanding what you need. Lets review the various types of CCTV security recorders to better understand what to look for.
Benefits of Surveillance Camera Video Recorders
Camera Channels - NVRs (Network Video Recorders) and DVRs(Digital Video Recorders) come in various sizes. Typically you will see these systems in 4, 8, 16 and 32 channel (camera) systems. Having 16 channels will allow you to have 16 cameras on one system. This means you can record 16 cameras on one system. Most people tend to go with these recorders because of the large capacity of camera channels they can use. Even if you only need 5 cameras to start, a 16ch NVR or DVR will allow you to have growing room.
HDCVI VS. HD-SDI
Longer Transmission Distance.
Both HD-SDI and HDCVI can transfer HD video @720p/1080p, but HDCVI currently has the distinct advantage of transmission distance. HD-SDI in general transmission of media reaches 100 meters at most, while HDCVI can transmit 500 meters by using 75-3 cable and offers low signal distortion rate.
