UVD-IP-XP4DNR(-P) Camera  9 - EN 
Day/Night 
This function controls whether the camera is in automatic day/night 
mode or forced into night mode.  When set to Auto Day/Night mode, 
the camera produces high-quality color video during the day or when 
light levels are high. It then switches to monochrome and removes the 
infrared filter to improve IR sensitivity at night or when light levels are 
low.  Black and white mode forces the infrared filter to stay removed 
therefore the camera stays in black and white mode. 
Resolution 
High resolution produces higher quality images but also increases the 
file size of the video images. 
Flickerless control 
Flickerless control eliminates the flicker caused by the differences 
between the frequencies (60 Hz) of the ionization of the gas in a 
fluorescent light bulb with that of the vertical frequency (59.95 Hz) in 
the camera. Although the difference is very small, it results in a slight 
flicker at the top of the monitor scene or, in video over IP applications, 
it would be interpreted as motion. Flickerless control helps reduce the 
file size and transfer bit rates of compressed video images.
