Day/Night
Switch the video images for Day (plenty of light) or Night (Low light) scene. In “Auto” mode, camera
will switch to Day or Night vision according to the light intensity.
The switching of Day/Night modes includes 3 actions; switching IR Filter
In / Off , turn Off / On IR
lamp, and switching image to Color / Mono . In day mode, the IR filter is switched in to avoid the
image sensor from receiving the infrared, and the IR lamp is turned off, thus the true color image is
provided. When camera enters night mode, the 15M IR lamp is turned on, and IR filter is switched off
to allow IR illuminations going into the sensor, thus increasing the images light level. The image color
is switched to B/W (Mono mode).
