The last 20 years have seen the CCTV market undergo a transformation on the back of a global changeover from analogue to digital recording.
“No longer do video cassettes have to be replaced on a daily basis or fast-cued to find an event,” says Zane Greeff, technical director of Elvey Security Technologies. “Technology has evolved to such an extent that it is not only incredibly user friendly but also highly effective, thereby guaranteeing convenience and a pleasurable interaction between user and digital video recorder (DVR).”
Samsung has now released a new DVR, the SHR-7160. Replete with 16 channel CIF (Common Intermediate Format) resolution and audio and video output, it is a real-time standalone DVR for small to medium-size applications.
With MPEG-4 compression video recording and ADPCM (Adaptive Differential Pulse Code Modulation) compression audio recording, the SHR-7160 delivers high-end video and audio quality on all 16 channels. Its standard 500 GB SATA hard drive can be increased by an additional five drives, thereby accommodating the requirements of businesses wanting to record for longer periods of time before the DVR starts re-writing over older recordings.
Viewing of live or recorded footage is enhanced by the DVR’s spot monitor output, which together with composite BNC, VGA and HDMI output for the main display monitor, allows for playback speeds of 2, 4, 8, 16, 32 and 64 x normal speed.
Back-ups can be done using a range of USB devices including memory stick, external DVD writer, external hard drive or external CD writer in AVI, EXE or DVR format. Alternatively, a DVD writer can be ordered as an optional extra.
Thanks to its built-in Web browser, live images can be viewed via the Internet and event notifications can be received via e-mail, depending on the parameter settings. These settings encompass motion, alarm, video loss on any channel, power on or off, normal recording start or stop, and notification of hard drive problems.
