In addition to its video surveillance functions, the QCN8001B is able to accept input from other devices and either pass their signals back to an NVR, or utilize them to trigger recording or alert actions when it is being used in a stand-alone role. The camera has 32GB of internal memory allowing it to record video and still images without the need for an NVR.
By using the audio input and output to connect both a microphone and speaker - and with similar audio equipment on the user's end, two-way communication can take place. Two alarm sensors can be connected to the alarm block with a single output to an audible alarm, an external alarm input or to a DVR. When used with an NVR or on a network, the alarm signal can trigger recording and its signal can be transmitted via the Cat 5 cable to an NVR.
