Monitor your home or business with levels of clarity and detail never before possible with Q-See’s completely digital, high-performance 8 channel Network Video Recorder.

The Q-See NVR’s ultimate benefit is the flexibility it affords through its ability to operate and connect with remote IP cameras. This single NVR manages and records up to 8 cameras simultaneously regardless of where each camera is located. In addition to the convenience of monitoring various properties, enjoy an extra layer of security by placing the NVR in a safe, low-risk location to limit access to the system and its critical recordings. 
The QC838 supports IP PTZ cameras through the CAT cable without extra cables for power and control wires. It also supports audio feeds through the CAT cable for cameras that have microphones so no additional audio inputs are needed.
The system is calibrated with 1920x1080 color-rich image quality to maximize the clarity and detail of people and actions including, facial recognition, license plate identification, currency validation and more.
