Are they any good, these days?
We've now got a daag and the internal PIR's of our (wired) system are not pet friendly. I'm sure I can probably put new PIR's in their place but the alarm system is now about 15 years old, hasn't been serviced in our ownership of the house, sounder battery is possibly kaput and frankly doesn't give me the features/flexibility I want.
Had held off with any replacement as we were (still are) planning on having an extension built which, with the disruption, meant we could probably fit a new wired system without causing much more hassle. But given the extension process seems to be an ever moving target and the wife sometimes freaks herself out when she hears a noise, I might have to do something in the meantime.
Not bothered about paying through the nose for some pointless monitoring service and not bothered about a police response. A dialler/sms facility might be handy and an easy method of access (RFID tags? Remotes?) for the in-laws too but it's mostly for deterrent value and making things uncomfortable for any miscreant who finds his way into the house (or garage). Not convinced by any of the Alexa/Google integrated stuff like Nest at al. I'd would obviously prefer something decent and flexible which is not necessarily whatever is available from the nearest DIY store, e.g. Yale or whatever.
Last time I looked at them with any seriousness, there were questions over the security of their wireless connectivity and alarm brains being scrambled/overwhelmed by broadcasts on the same frequency. Is that type of thing still an issue.
Are there any pro/semi-pro/respected brands out there that are worth looking at?
