Glossary
Video Loss: Is regarded as a potential alarm event and is considered to occur
any time your DVR or NVR doesn’t receive an active video signal from any one
of its video inputs.
Video Quality Diagnostics: Enables your DVR or NVR to alert you if the cam-
era has a blurred image, abnormal brightness or unwanted tint in the image
due to the lighting and white balance of the camera (known as Color Cast).
Video Stream: Indicates that your DVR or NVR is recording a video stream
only.
WDR (Wide Dynamic Range): Is technology to balance out images that have
a large dynamic range. An example of this situation would be if an indoor
camera were pointing towards a window or building entrance. The image
produced by the camera during the day would be extremely washed out due
to the high brightness of the incoming light.
