Which is a very fair point but as I said I am retired so the install would be fun even if it took time. Having said that, I have been messing with the existing system which was giving internal tamper alarms when not set. Have run it to ground ( I think) a bedroom PIR that had been taken off the wall by a decorator, put back loosely, and which was behind the door that the dog comes crashing through every morning. In the going, however, I seem to have gelded the outside siren and light.. One loose wire in the main box is I suspect the culprit, but not had time yet to work out where it goes. As you say, an instalkler could well have solved the whole issue in no time at all.

physics degree and ham radio means I am OK with the basics of installing and maintenance, and the existing system has simple walk throug testing and fault codes. So maintenance has been a matter of a check that everything is functioning correctly and the replacement of batteries in both control box and siren box. I would like to DIY a new system - I'm retired and its something interesting to do with my time. Bit if a modern system involves networks etc then I would struggle.

we have a scantronics 9800 in the house we bought in 2005 - it has worked OK but we are now getting a few problems so I need to decide repair or replace. Cant help but think that electronics has moved on leaps and bounds since the 90s when this system was installed and in any case we would like to extend it to give more coverage. Maybe add outside security too. So I am seeking opinions on what to go for. We are talking a three bed detached bungalow. Currently there are 2 magnetic door sensors and 2 movement sensors plus a bedside panic button, inside and outside sounders all hard wired and with the wires installed during building. I dont want to be cutting channels in walls and completely redecorating to extending the system implies wireless. Do any modern systems also link to outside cameras?
