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
Try reinstalling the graphics drivers , I always found that getting the graphic cards drivers from its manufacturer is better and Upto date and other versions are available
Only if its a graphic problem
You could get your self some ir beams if its just an area you want to cover as in someone walking past or across your drive , beams could still trigger a chime or other things depending on how far and techincal you can go

Geezer it won't last
Option1 strip out the bellbox and buy a flashing led kit with battery pack
Option2 drill hole through wall use power adapter to power leds in stripped out bellbox
What your doing as said above won't last
No battery shouldnt make difference, although faulty batteries can damage the panel
You do realise test is just an approx 5sec burst and it will change when you take that off?
