CCTV CAMERA FAQ’s
What is a Security DVR?
DVR stands for Digital Video Recorder. A Security DVR is capable of taking the video from digital or analog cameras and recording it into a digital format on a hard drive. It can record high quality video, maintenance free, for weeks or even months. An ideal replacement for time lapse VCRs.
What is a video capture card?
A video capture card or DVR card is a graphic card inside the Security DVR system which captures the signal from the cameras and stores the video on the hard drive.
How many hours of video can the Security DVR store?
The length of archive depends on number of cameras, frames per second (FPS) and amount of available hard disk space. Our preconfigured systems usually provide several weeks of archive on motion detect mode.
How does motion detection work? Through the camera or software?
Motion detection works through the software in the DVR system by recording video when pixels in the image change. Most Security DVRs offer a sensitivity scale so the user can set the sensitivity of the motion detection.
