Why can't you just have another unit to talk back from near the DVR ? You want record the convo I assume aswell? Just split the mic
I may be way off what I understood of your question tho.....
You may have two companies in one building three groups
Common - only sets of conditions met
Floor one - set by first company , also sets common only if floor two is set
Floor two - set by second company, also sets common only if floor one is set
That's one way of doing it, others will correct me if I am wrong
Dudes anything you can recommend cheap and cheerful is the word , have a customer with some weird NVR that supports onvif so looking for a small ptz that will work via onvif , or you think that will be a mare? Chinese will do if you know is it works .....
Personally , I am a professional house basher , so I got mad lab setup at home and try everything before going out
I havnt used these , but I guessing I prefer the texecom version , more striaghten forward
Regarding the terminal if it's just short then no , if there's electronics involved then maybe
What about the jumpers have you set them right?
Not that I know but guessing
System - engineer
Tamper - engineer
PA - manager
Line Fail - user / manager / engineer on some
Fault - depends on fault
AC Fail - user
Not that a house basher is affected much by it either
I knew that was coming though, come on seriously, I can't sleep much and spend time getting depressed on Tsi only to find it's offline because you won't give it to a real host in Brighton
Does it have an automatic reboot facility so it can miss it's usually crash behaviour
