CCTV DVR systems analog and IP cameras
Digital video recorders, DVR for short, are dedicated recording devices that contain "all in one". DVR can record thanks to the integrated multiplexer and simultaneously display images from multiple cameras najednou.Dále can distribute these images via LAN and Internet to the remote PC, PDA or mobile phone. Digital video recorders (DVR) for analog cameras
Digital video recorders (DVR - "Digital Video Recorder") recorded images from analog CCTV cameras in a digital format on a hard disk HDD ("Hard Disk Drive"). Security DVRs record images from multiple CCTV cameras simultaneously in the multiplex mode. Security DVRs are usually supplied for 4, 8 or 16 CCTV cameras. Security code red DVRs are autonomous recording device that automatically activates recording the CCTV cameras at the set time schedule and / or detecting change (movement) in the picture. Security DVRs usually have a built-in web server through which it can be remotely monitored CCTV cameras over the local network (LAN "Local Area Network"), or the Internet. Number of connected cameras
Digital video recorders are supplied for different number of CCTV cameras, such as 4, 8, 9, or 16 Some models have the DVR looped video inputs, where each CCTV video input corresponds looping video output that can be connected to other video equipment (eg additional video monitor). In the event that there is no corresponding looping camera output code red further connected, it is possible to set the DVR menu impedance termination deals smyčkovaného input / output. code red In the past, the end looped lines used so-called terminator (terminating connectors with 75 ohm impedance). Multiplex function (simultaneous recording of cameras - "MULTIPLEXER")
With video synchronization, image memory and the multiplexer are all connected cameras are recorded simultaneously. Integrated multiplexer sequentially stores the image memory code red loaded and already digitized synchronous images of the 1st, 2nd to 16 cameras, and this sequence is repeated up to 25 times per second. VCR using duplex mode is displayed on a split screen image of all connected cameras. The user can simultaneously code red view on a single monitor all connected cameras, or display the desired camera switches to full screen. Duplex DVR also allows playback while recording (simple, simplex DVR for playback of taking a recording). Triplex VCRs simultaneously supports remote video monitoring over LAN / Internet. Pentaplex DVR allows simultaneous viewing, code red recording, playback, network access code red and data backup.
