The PTZ cameras are a bit more money but worth the bit extra for the Zoom alone.
The fact that these pan reduce the need for extra cameras so they save you money that way.
I had been using EasyN PTZ cameras and received a XX60A As a late Christmas present.
I had attempted to place this in a trouble spot I experience with a EasyN camera but had the same issue there.
I decided to place this next to another Easyn cam mounted in another location.
On first start up I couldn't get this to connect So my attempt at the trouble location may not have been the location.
After several experiments with antenna angles I unplugged the camera and the plugged it back in.
Viola!
these cameras are almost identical to my EasyN cameras except the EasyN camera has a clear dome verses the smoked Airsight one.
This made me expect a darker picture but as you can see in the attached side by side comparisons that's not the case.
I plan to do some experiments over the next week with night vision and over all performance.
As of now I'm impressed with the day time picture. Attached is one from the Airsight interface and another from the EasyN interface.
I wanted to be sure it wasn't just the Airsight software.
The EasyN cam is mounted directly above the Airsight about 3 feet higher.
