The Huisun Mini Bullet PTZ cameras do not have auto-tracking. If you want auto-tracking in a Huisun camera, you need to get one of the PTZ Dome models.
I'm now the owner of both.
Had the dome for a while and just received the mini ptz.
First initial thoughts are:
The dome has a quicker ptz mechanism indicated by the word "speed" dome
Also the dome has the day/night option seperate from the ir menu which makes it easier to work out the day/night switching settings .
The mini ptz only have options in the IR settings. I assume they do the same thing as neither can allows scheduled switching just auto, on and off with sensitivity setting.
The image quality looks great on both especially at night!!
I was literally blown away by the night images of the dome when I got that and I was Avon when I received the mini ptz yesterday.
The mini ptz is quite large in comparison to the hik 2032 models.
But I prefer my cameras to be seen, less chance of the crime taking place that way!
In comparison to the hik 2032 purely on picture quality it's a clear winner for me!
The most important thing to me is night image quality and the Huisun is way ahead.
This most likely down to the exir leds.
I'm sure I also read somewhere that Huisun used a better chip than hik as well
