The NVR has no built-in audio output. To hear sound, please connect the NVR to an HD TV or monitor via HDMI and ensure the camera supports audio. Two-way audio is available through the mobile app only and requires the system to be connected to the network. The system supports both 2.4GHz and 5GHz WiFi connections.
Dual WiFi System: The cameras connect directly to the NVR through its built-in WiFi, so pairing does not require an internet connection. The NVR is a network video recorder with an integrated WiFi router, designed to handle camera connections independently.
The wireless NVR requires a 12V 2A or 12V 3A power adapter. Using a 12V 1A camera power adapter with the NVR may result in insufficient power, which can prevent the hard drive from operating properly.
