I got both of this cams and they work fine in Zoneminder
Mine are both doing 640x480 in colour now.
Settings:
Create a new Montor
set it to be a remote device
as source:
remote host: http://user:pass@ipofcam
port: 80 (or whatever you set it to)
path: /cgi-bin/video.jpg
user:pass must be a combo that has access on the cam wit privielleges to watch pictures. Use the admin user if you don't bother.
Just the PTZ Controls of the TV-240 don't work in Zoneminder here..
