Issue Description
Applicable Models:
VS-IPC-H14M

Symptom:

The VS-IPC-H14M box camera is configured with an external infrared light to enable 24/7 surveillance. Images of the IPC frequently change from the black/white mode to the color mode after the infrared effect is enabled at night.
Handling Process
Step 1 Decrease the sensitivity for day/night switching of the IPC.

1. Log in to the IPC web page as the admin user.

NOTE:
For details about the default password of the admin user, see the user guide for the device.

2. Select Configuration.

3. Choose Remote Configuration > Camera Settings > Front Para Config.

4. Set Night → Day to low.

5. Check whether the fault is rectified.
   a. If yes, no further operation is required.
   b. If no, go to Step 2.

Step 2 Check whether the infrared light and IPC use the same power supply.
  • If yes, check the voltage and current of the infrared light and IPC and ensure that the voltage and current meet the working power of the infrared light and IPC. If the actual power supply is lower than the IPC's minimum working power, connect the infrared light to another power supply.
  • If no, go to Step 3.
Step 3 Check whether the specifications of the infrared light meet the onsite requirements.
  • If yes, contact your service provider for assistance.
  • If no, replace the infrared light with a qualified one.
NOTE:
If the irradiation distance of the infrared light is too much longer than the actual distance, images change from the black/white mode to the color mode frequently.

Step 4 Check whether the fault is rectified.
  • If yes, no further operation is required.
  • If no, contact your service provider for assistance.

Root Cause
The possible causes are as follows:
  • The sensitivity for day/night switching of the IPC is too high.
  • The voltage of the IPC is insufficient after the infrared light is on because the infrared light and IPC use the same power supply.
  • The infrared reflected brightness is too strong and exceeds the sensitivity value for day/night switching because the irradiation distance of the infrared light exceeds the actual distance.
