Security Labs SLD251B Refurbished 4-Channel Digital Video Recorder With Lan

The SLD251 DVR is the solution for applications that require one to four cameras to be recorded simultaneously. Fully multiplexed, each camera can be played back full screen. Cameras can be viewed live in quad (four per screen) or full screen. Built in video motion detection can be set to place the DVR in record automatically when any camera detects motion. The removable hard drive slides out to allow for archiving or expansion. In quad mode all four cameras can be viewed and recorded at 30 images per second. In mutilplexed mode (MUX), individual cameras can be recorded at 7.5 images per second (7.5 x 4 cameras = 30). Four adjustable compression levels give the user additional control over total recording time. The hard drive can be set to automatically write over the oldest video when full so that recording can be non-stop. Continuous, manual, event, and scheduled recording is available. Four alarm inputs are included to automatically place the DVR in the record mode when event recording. A time and date event search allows for quick location of important video. The DVR can be viewed via the internet with a web browser. Playback, full screen viewing, and operational controls can be accessed from any location.
