Explanation of the Wide Dynamic
Under the "strong" light environment such as the building entrance and bank entrance, the image performance will become extremely white or blacked. It is due to the camera capture the image is based on the 7 positions .normally, choosing the central positions and "strong"light source. With the Wide Dynamic function camera, it can adapt to every lighting condition automatically without any adjustment.
Explanation of the Slow Shutter
Under the extremely "low" light environment such as the Museum (Prohibited use IR) and Research the animals in forest (night time), so, the Slow Shutter is using as the ram memory technology to accumulate the 3 to 4 blur images (which are caused by the light sources not enough) to perform a clear image. by the Slow Shutter function, the min.illumination is 0.008lux/F1.2.the maximum accumulate frame is 128. Normally, by the international brand camera, currently maximum is around 32 frames.
Explanation of the Line-Lock
Normally, the power supply (DC) and the fluorescent lamp are in different phase (said internal sync).it makes the color of the image is changing continuously and so it seems to be unstable. With Line-Lock function, the power input is AC and the design will make the power phase is keep the same as the fluorescent lamp (said external sync).so ,the color will not "rolling "and keep the image performance constant.
