Personally I wouldn't. From experience the various false alarms you get from using 'line crossings' and 'intruder detection' wouldn't make them reliable enough for me to use them purely as an intruder alarm. If he's asleep - he's going to miss the little ping notifications. If he wants an alarm with an auto dialler - look at the hikvision axpro range. They have the option of installing a simcard - which on alarm activation will call your mobile and tell you the alarm has been triggered. Aside from the 'brains' that needs mains power - the rest of the system is wireless with batteries (replaceable) that last around 3 years.
Android you can set custom notification sounds for individual apps, I have Hikvision notifications set to eye of the tiger MP3
. IOS on this part is pretty poor, as it doesn't allow custom app notifications and the default "ping" is all you get. On the "various false alarm point". I have 4 DS-2CD2387G2-LSU/SL configured around my property, I have now got these fine tuned to literally 0 false alarms. Target detection combined with a minimum size is a game changer. I don't have a house alarm as I am pretty confident the audible warning alarm that rings out on all 4 cameras if 1 camera is tripped would be enough to deter any opportunistic burglars. The alarm is set on a schedule between 11.45PM and 5.30AM daily. I work from home so daytime isn't an issue.
I also utilise Blue Iris with Deepstack and MQTT requests to Alexa that turns on all the lights in the property and also turns on 2 TV's with Firesticks connected to them and plays youtube videos at a decent volume on the above schedule.
I also have 4G sim in my router as a backup.
I was burgled in March which was an awful situation. I spent a good chunk of change having all the doors replaced to strong composite and Ultion 3 star plus locks. I have also had the glass replaced on all the ground floor windows to 6.8mm laminated glass
If they manage to get in now without me knowing and without waking me then they are professional burglars, but I have done more than 99% of people so pretty sure they'll move on to the next house.
Having an alarm is ok, but if the alarm is ringing, then at that point they are already in the property and it is too late, your sense of security goes out the window. Deterring them at the perimeter of your property with an alarm from within Hikvision camera and strobing lights is a much better approach imho, but each to their own.
