The camera Melvin was mentioning can be
tested here
I don't only own an expensive Axis 214 but also two cheaper IP PT(Z) cameras.
Z in brackets because it's AbelCams digital zoom, no optical zoom:
- LevelOne FCS-0020
available at around 220 USD as well, currently
on display here in a 90° rotated configuration
acceptable image quality, max size 640x480
- LevelOne FCS-1060
available at around 220 USD also, currently
on display here
lousy image quality, but great Pan/Tilt range
- Panasonic BB-HCM311
at around 330 USD,
test it here
There are many different Panasonics with different features (and price tags), the one above does a good job.
Unlike the TrendNet and the LevelOne cameras it has positional feedback. Even if you use the cameras built in
web server to look around AbelCam will keep track of the position.
The LevelOnes linked above are set up at 2fps, they can be faster of course.
The Panasonic runs at around 5fps, the TrendNet at 3fps.
There are many other IP cameras around which also work in AbelCam, but I have not tested any of them.
As long as they can deliver Motion JPEG and/or JPEG images and be controlled with HTTP GET requests,
they can be used in AbelCam.
