SECTION 1: LED Supplement Light Brightness Configuration
NOTES: When the camera is first supplied power, it performs a self-check with the supplement light at
full power, so avoid staring at it.
The LED supplement light will lock in the light-on state for an hour if is repeatedly switched five
times within a short period of time due to manual testing or ambient brightness changes.
1. Enter the following path to go to the configuration settings: Configuration > System > System
Settings > External Device.
1.1 Enable Supplement Light

SECTION 2: Configuring LED Light On Mode
The LED Light On Mode can be set to Timing or Auto.
2.1 Timing Mode
• By selecting Timing in LED Light On Mode, the camera will turn on/off the LED supplement light
according to the Start/End Time.
• Set the schedule time according to application requirements. The Start Time should be earlier than the
End Time. The Start Time can be on the previous day of the End Time.
Figure 4, Configuration > External Device: LED Light On/Timing
2.2 Auto Mode
The camera will detect ambient brightness automatically in Auto Mode and turn on the LED light
automatically. The mechanism is similar to the automatic adjustment of the infrared supplement lamp.
1. Set the Filtering Time in the range of 0−120s.
When the ambient brightness exceeds the light limit and lasts for a period of time (as shown in the
picture below: 5 seconds), the camera begins to turn the light on and off. This setting prevents the
camera from continuing to turn the lights on and off when the brightness changes rapidly.
2. Set Sensitivity in the range of 0−7.
The lower the sensitivity, the greater a change in ambient brightness is required before the camera
will turn the light on/off. The higher the sensitivity, the lower the ambient brightness change required.
3. The default mode is Auto. Adjust the parameters or customize the firmware if the light needs to be
turned off by default.
