This looks like a side effect of owning cams with Chinese interface

What is the alarm function used for? I'm not sure why I would use it.

If they are steppers motors (which is obviously the case), speed depends upon firmware.
Who knows we are currently at maximum speed (allowed by hardware)??

Pretty sure they're not steppers. They certainly don't make the noise of one. Much simpler to drive brush motors.

How would you design such a motorization? I certainly would'nt rely on timings to achieve accuracy in
positionning. So the other alternative would be servomotors.

But I am not sure analog servomotors would lead to such an accuracy... We will see over time when temperature and other elements vary. It will give us a definite answer.

Another clue: https://en.wikipedia.org/wiki/Servomotor
You can extract:

Therefore, on first power up, the controller will have to activate the stepper motor and turn it to a known position, e.g. until it activates an end limit switch.

That's exactly what our mini ptz does at start. A servomotor does'nt need that.

You make very good points. I wonder if their $35 analog camera has the same drive mechanism (probably). I think I'll buy one - at a minimum it will fun to take apart. Might prove to be a good source of replacement parts for the PT portion.

Just got my third Huisun mini ptz up and running. No matter what some may say, I think these are really great cameras for the price. I have three now and will probably wait for the 2nd generation to be released and might order a few more to replace my Hik's and other cameras. You get kind of spoiled with PTZ as others have mentioned. I especially like the capability to zoom in on a subject.

I am spoiled and I want more! Well by more I mean even better

Our 2nd generation mini PTZ camera is in final testing now.
Monica will inform you once it is available.

Peter

Hopefully we get choice to buy v1 or v2. Personally, i'm extremely happy with mine!

Ok, but I want to deal with Candy.

Actually, I sent another request to Lucy couple days ago, but reply came from Peter today

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:

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):

Code:

... 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. The image quality is only acceptable when highly illuminated.

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.
