Understanding digital video recording systems
DVR stands for Digital Video Recorder. A Security DVR takes video from digital or analog cameras and records it in digital format on a hard drive. It records high quality video, maintenance free, for weeks or months.
A video capture card is a component inside the Security DVR system that captures signals from cameras and stores the video on the hard drive.
A Security DVR is digital and records to a hard drive with high quality. A VCR is analog and records to tape with lower quality and limited storage.
Storage depends on camera count, frame rate (FPS), and hard drive space. Our systems typically provide several weeks of archive on motion detection mode.
Motion detection works through DVR software by recording when pixels change in the image. Most DVRs offer adjustable sensitivity settings.
Most DVRs restart automatically when power returns. We recommend an uninterruptible power supply (UPS) for backup power and surge protection.
