DIGOPTIONS/MASTEN WIRELESS CAMERAS

[FANTUM]

Greetings kids,
I have a DigOptions/MASTEN wireless camera system (3 cameras) and now only one camera, the oldest) will pair with the monitor.
The other two are relatively new.
Until this problem started I was very happy with the wireless system.

If anyone on here has a similar system, have you had a similar problem?

I've been trying to contact DigOptions for several months now with no response at all, despite numerous emails, phone calls etc.

Does anyone know if they are still trading?

Someone suggested that, since my (5") monitor is about 4 years old, the two newer cameras might not be compatible, any thoughts on this possibility?

Cheers
