Wait a minute...
Has anybody checked the actual video bitrate of this mini PTZ?
Here is a comparison with my Hikvision's DS-2CD2142FWD-IS:
Same video configuration:
View attachment 6708
Method 1: Check bitrate through network (DU-meter):
Code:
Huisun: 0.88 Mbps average
Hik : 4.62 Mbps average
Method 2: Save video (10 minutes - NO REENCODING) with BI:
Code:
Huisun: 57 Mb
Hik : 313 Mb
Method 3: Check files (Media Info):

... and I was wondering why I was the only one to find the image quality awfull.......:sad2: Macroblocks all throughout the picture, especially in dark areas and at night. I suspect Huisun to virtually improve image quality with 3D optimization, ie average of several successive frames. This may works with still images, but not when there is movement.
This is not HD.
Sorry to say that, but what are your numbers, you who claim image quality is marvellous??? or... what am I doing wrong?? Is my camera defective?
Maybe I am too much used to HD movie processing, that I am doing everyday... Remember old DVDs that required at least an 8Mbps bitrate.... Whith Huisun, we are talking 10 times less! with a 2Mpix image vs 0.3Mpix !
It goes without saying that I tried all possible configurations from low bitrate, variable encoding to highest bitrate (10240 Kbps that turnsout to be about 2Mbps) and constant encoding.
Please give your numbers using any method.
