Well, didn't know it was that easy to make you laugh. The thing that made me laugh is that you took time reading my post, not understanding it, and instead of giving advice you critisized my 600 USD DVR. And that's something that tells more about you than me.
For your information, the PTZ is 100x digital zoom. And the price for it: 263 USD
The DVR, i'm getting it for 366 USD. And the cameras go for around 40 usd each with Sony Super HAD CCD II
Anyway, that all was not the main subject. The subject was to link an alarm system to a CCTV DVR. I'll have a talk with one of the engineers of the factory on Monday to see if the Alarm out can trigger an alarm central.
