Bin it , and get something you can work on , or as mentioned by yourself being out of trade they won't be to fussed to help you
To be fair , all these house basher's between them have used most of the good equipment, you sure it isn't shenzen job?
Because he hasn't used leisure batteries perhaps , standard batteries you will need to many, they will drain quick and die
What about a battery monitor send a low battery warning
Now you really have lost me , what trick?
You asked what equipment , i was only referring to previous comments of esp equipment
You need to chill man , I already got laser sighting on one leg
So 300 quid you install it, and then have to keep going back when it doesn't work, if components fail then each visit and fault find becomes chargeable agreed? Hence fit your own kit and charge accordingly
Including labour? If your really into that stuff there's stacks of junk on eBay even cheaper ,
But is this really your business model? Stick whatever you normally fit and say you don't fit that
Yes because most diallers will use a neg or pos trigger
I don't know your panel but does it support dtmf contactID ? Otherwise stick to a standard gsm unit
Positive , negative , bell trigger to input of gsm unit will do it
Any gsm dialler , but better get a monthly SIm deal , and then again to get good use of it change the panel so you can get full notifications , otherwise you have keep an eye on a payasyou go chip
