NVRs (network video recorder) and DVRs (digital video recorder) are what you use to manage, view, and store surveillance videos. Available with a variety of software and hard drive sizes, NVRs and DVRs make it easy to save and review videos. Which one you need, and how it works, depends on having CCTV or IP surveillance cameras.

Plug and play with local PoE ports_NVR

The VMAX® IP Plus™ NVRs can power up to 16 IP cameras locally from the system itself, no need for PoE switches and additional power sources.


DW’s CCIP (Closed Circuit Internet Protocol) camera and recorder encryption is an exclusive DW technology that provides an encrypted RTSP stream between the camera and the recorder , assuring users their cameras, recorders, and data are secured. The feature is available for all MEGApix® single-sensor IP cameras as well as VMAX IP Plus NVRs.

The VMAX IP Plus system sends a request for an encrypt stream from the camera, which in return encrypts its RTSP stream a second time, over the user ID and password. The secured and encrypted RTSP stream can only be read by the requesting NVR.
