DSS - Digital Slow Shuttering explained

First, please read the preceding paragraph above (AES) to understand about shuttering in general.

In essence DSS is trickery and at best a trade-off, but not really a technology that enhances any signals. DSS basically electronically spreads the light reflected onto the CCD chip of the camera, onto fewer images per second. This leads to drastic increase of the usuable illumination LUX, often to the point of operation in star light 0.0002 LUX and lower. DSS generally impresses customers more than Infra Red camera video, as it is often producedin colour and seems to give brilliant footage at all times. One has to however consider the trade-off in images reflected per second. Moving objects are therefore displayed a lot less crisp and sometimes completely blurred. If people and moving objects are to be detected by the system, we suggest a demonstration or trial before committing to buy. An easy online video demonstration might do.
