FAQ
- I’ve just hooked up my NVR4CH and I can’t access it—I’ve tried the default password “123456” but it won’t let me continue.
- The NVR4CH comes with no password out of the box. You can simply press enter when asked for a password. Remember to set one up from the menu later!
- The video from my camera is corrupted.
-
By default, the NVR main stream is set to 720P, while your camera stream may be set to 1080P. Setting the NVR’s stream to 1080P solves the problem.
To change the NVR’s main stream format:
- Open the NVR’s settings menu
- Navigate to Device > Device Info
- Change “Video Format” to either of the [1920×1080] options
- Reboot the NVR and the problem should be resolved.
