2.1 IR effect is bad.
Possible reason 1:
Users didn’t use specified power supply, and failed to enable all the IR lights.
Possible reason 2:
The object is so far that it is out of the range of IR light.
Possible reason 3:
IR-CUT is set as color mode, which caused the front-end sensor to fail to sense IR light.
Possible reason 4:
When you use the device on the table (especially rough surface), the IR light will shoot back to the lens, which will cause bad IR effect and white picture. At this moment, you should adjust the elevation angle of the lens or place the device on the edge.
2.2 The device failed to record or snapshot.
Possible reason: “Snapshot Schedule” is set wrongly; storage path is not correct; “Record Mode” is set as off.
Solution 1: Set “Record Schedule”, “Snapshot Schedule” in the WEB interface; please refer to the <IPC WEB Operation Manual> for more details.
Solution 2: Check if the “Destination” enable in the WEB interface is checked.
