Network CCTV recording system by Dahua with 4K resolution and 16 channels. In the case of network video recorders (NVR), the video data processing is done on the connected cameras, which are then transferred to the recorder for remote viewing and storage. This means that NVR systems are compatible with IP network cameras, which offer higher resolution video than an analog camera, and can be connected to the central unit via ethernet cable or wirelessly, when both the recorder and the cameras have Wi-Fi connectivity capability. The number of channels of a recorder corresponds to the number of inputs it has for the wired connection of the system's cameras.

The DMSS application is available on the iOS App Store and Google Play. It makes surveillance easy and simple, allowing you to remotely access back-end devices, view live video, receive push notifications for events, and search recorded videos from an iPhone, iPad, or Android phone at any time from almost anywhere.
