Video Server (Encoder) = This enables an analog camera to be converted into an IP camera, able to stream digital video over an office network, phone, or ISDN connection. Therefore, an analog-based surveillance system can be upgraded and networked to function as an IP surveillance system. Video servers are particularly useful when a user has existing analog (CCTV) cameras with BNC (coaxial) cabling, that they are perfectly happy with…they just want to lose their DVR and upgrade to an NVR to gain some features, perhaps the ability to remotely monitor the system. In this scenario, you can get rid of the DVR, and plug the analog cameras into a 1,2,4,8 or 16 port server, which is then configured for your NVR system. ACTi and Axis are two examples of video servers that we offer.
