True Day and Night (TDN)

“True” Day/Night cameras work by implementing a physical Infra-Red filter that is removed by a small motor. When the camera enters day mode, the filter is placed in front of the camera element, filtering the Infra-Red and providing a true colour image.

When the camera enters night mode, the motor moves the Infra-Red filter out of the way resulting in a black & white night vision image. This provides the advantage of a night vision camera with superior image quality during the day. True Day/Night cameras usually only cost a little more than their regular day/night counterparts.

Smart IR

Automatically adjust the infrared light output required in a scene as the object moves closer or further away from the camera. On the side where the Smart IR is turned off it becomes impossible to make out facial features and details.

Sense up

Sense-Up: An image processing technology which allows user selectable digital slow shutter speeds in order to allow extra light into a camera thereby providing higher sensitivity in low light conditions. Also referred to as “sens-up”,” sensup”, “senseup”, “DSS”, and “digital slow shutter”.

Digital Noise Reduction (DNR)

The chip inside your camera is constantly picking up noise from interference and byproducts produced by other circuits and electronic components within it. These noise artifacts can translate into images and video as fine static, snow or fuzzy images.

Digital Noise Reduction (DNR) is a method by which the camera’s imager digitally removes noise from the image. 3D DNR is an advancement of this technology which enables noise to be filtered even more effectively from the image, even in low light conditions.

wide dynamic range (WDR)

The wide dynamic range (WDR) function of a camera is intended to provide clear images even under back light circumstances where intensity of illumination can vary excessively, namely when there are both very bright and very dark areas simultaneously in the field of view of the camera. WDR enables the capture and display of both bright and dark areas in the same frame, in a way that there are details in both areas, i.e. bright areas are not saturated, and dark areas are not too dark (WIKI)

highlights Compansation (HLC)

Detects bright highlights and masks them out in order to reveal detail which would otherwise be obscured by the flare effect from a strong light source, such as torch light or car headlights
