With the Servalan network video recorder (NVR), uses can record 18 HD cameras in full HD for 31 days in real time, say the manufacturers Tecton.
The makers point out that the 1.5U high, rack-mountable product is not a PC, so that anti-virus software and updates are not required. The hard disks are removable from the front panel while power is on and recording is taking place. The recorder’s disk capacity expandable in 30TB chunks. All disks are hot-swappable, including the disk being recorded to. Individual disks as evidence can be viewed by the police. You set up the product over the network, or directly from the front panel; the recorder accepts remote analogue cameras via Tecton’s Jigsaw, or other codecs. The NVR’s Nucleus IP control centre software can control up to 9,000 cameras.
