Video Preference
The video preference bar provides adjustment over the interval between each "I-frame" in the compressed
MPEG-4/H.264 video stream (IP55 does not support H.264 compression). In a sequence of images, there are
inserted I-frames that can show the complete representation of the picture one sees at a particular moment.
Between I-frames are what are called P-frames (which can be decompressed using the data from preceding
frames) and B-frames (which utilizes the data from the preceding and following frames for achieving higher
compression ratio). In essence, the shorter the interval between the I-frames is, the higher the video quality
will be (motion in video will also be smoother). However, shorter I-frame interval will raise the bandwidth
consumption of the video stream and lead to larger file size of the recorded clips.
Also, if you have set up the iDDNS service during the installation of IP camera, you can directly enter the web
address of your IP camera into a web browser’s address field and don’t bother with remembering the IP ad-
dress. (In this example below, replace the “compromk” with what you entered in the installation process.)

White Balance
This controls the camera’s white balance function. Different light source has different colors. White balance
function can make the dominant color light in a scene appear as normal white light no matter what the true
color of the light source is. Available selection: Auto (default), Sunny, Cloudy, Fluorescent Lamp, and Incan-
descent Lamp.
