I know this system has been going for a while but instead of an alarm system with D/C and PIR on every door will the internal PIR with video do the job?

Imo this system connected to the control room is a better option.

Possibly

We have a few out there, but remember they are fully wireless, no they don't make dt (to my knowledge) so that can reduce the environments they they can be fitted to.

We use a system similar but we got it installed on remote sites. 

 

We have them in use in the Sub Stations and Electricity Points,  They now caught a few people now since this system went in as it only records the actual event.

 

Our guys went to a farmer trade show last year and got a few farmers use this type stuff on there sites.  Its ideal to put in a shed, where you park your quad bikes and etc.
