1. The device does not have the Onvif function enabled. Please find the manufacturer to enable the Onvif function. 2. The device access monitoring software or NVR parameters are incorrect. The current default parameters for the company's camera to connect to the NVR are: username-admin password-123456 IP: can be seen in the device Onvif menu (usually a local IP address, in the WIFI router Below the gateway) Port: 8000 or 8899 (the port may be different for different customers) 3. The device video compression code is H.265, and the monitoring software or NVR does not support H.265.

1. The illumination in the environment where the equipment is located does not meet the triggering requirements. 2. The correct night vision mode is not selected or the night vision mode function is not turned on, and the device cannot switch between infrared night vision or full color night vision. 3. The device’s night vision mode switches abnormally, please contact the manufacturer for resolution. 4.

1. There is audio input/output signal interference near the microphone/speaker. 2. There is a problem with the microphone/speaker hardware, please contact the manufacturer for resolution.

Detect whether there is delay/stuck in the network, such as PTZ rotation, real-time video, and video playback.

1. The equipment testing environment has lights pointing directly at the camera. 2. Light refracts to the camera causing halo.

1. If the camera fogs up, you can place the camera in a place with direct sunlight to evaporate the fog (Note: Do not point the camera lens directly at the sun) 2. The camera heats up severely during operation, which affects imaging components such as CMOS and causes blur. 3. When the light is too dark or too bright, HDR or WDR is not turned on.

1. The brightness of the environment where the camera is located is low, and the IR-CUT switch is activated but the color light mode is not switched normally, causing the picture to appear purple. 2. The effect of light refraction, you can adjust the picture to see if it is effective.

You can put the upgrade program into the TF card for local upgrade. The upgrade process: 1. A TF card with the file format of FAT32 → 2. Put the upgrade program into the source path of the upgraded TF card (not under the folder) → 3. Power off the device, put in the upgrade TF card and then power it on again → 4. The device will be upgraded successfully and restart in about 2 minutes. After restarting, power off and remove the upgrade TF card → 5. Power on and test whether the device is working normally.
