Glossary

UID (Unique Identifier): Is an alphanumeric string that is associated with a

single entity within a given system. By entering your UID into the mobile app

or computer software, this allows you to communicate with your DVR or NVR

without having to remember IP addresses or port numbers.

UPnP (Universal Plug and Play): A network protocol designed to allow net-

work connected devices to automatically configure the router for the purpos-

es of remote access. Not required to be enabled when using UID.

VCA (Video Content Analysis): Is a new method for triggering recording and

events. This uses the image processing system of the DVR or NVR & camera

to set specific triggers for recording (such as line crossing or intrusion). This

system does use more processing power, therefore it may not be available on

all devices.

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.
