The integration with HA on the DSC systems I fitted where pretty impressive. You could control most options through the touchscreen media controllers everything done though a 232 BUS link.
Certainly very smooth interface with everything from the one place.
HA has moved on since then, it's cheaper to push everything to a mobile app now, and more people are used to that.
Gone are the days where you had media keypads integrated into your lighting controls on every doorway. More often this is being replaced for plug and play consumer tech like Lightwave and Sonos.
Used the Octoquad things as temporary scaffold protection and some early warning type perimeter protection.
They're OK but wireless is only one way, wired option available, good at picking up foxes...
I normally would suggest active IR beams, it depends on what your protecting and the environment tho.
The sensors are more expensive but compare that to the labour of installing shocks and contacts.
Also as you know aesthetics can be down to how well it's installed wired shock sensors could be installed more discretely than a PIR.
Lot's of variables, hence lots of opinions.
It's relative tho. You say bodge some say budget solution.
I would never guarantee that a pet friendly sensor would be fine there normally see how you go on a retrofit basis.
A new install I wouldn't consider movement sensors unless in combination with perimeter.
As in detection fitted to the perimeter of the room comprehensive enough to detect a break in.
This could be a combination of different detection to detect entry to the room. Contacts, Shocks, Active Beams etc etc.
No.
Dual Tech Pet is what's suggested but none are guaranteed to work hence why they are all sold as "pet friendly".
Never had an issue with sensible location of Bosch ones here for both active cats and dogs.
You can connect whatever detection you want to your alarm.
You need to bear in mind that contacts will only operate if the frame is opened.
If "window sensors" mean shock sensors, consider bird strike and cats jumping on the window ledges.
Coverage on perimeter is generally less so you need to design the system around this.
Perimeter protection in the areas with pets and movement detection in other areas is recommended.
I have had good results with Bosch Blu pet sensors but using a movement sensor and asking it to ignore certain movement is not ideal.
A good option would be installing movement and perimeter protection in the areas required and using panel programming to control the enabled sensors.
This will need planning, good knowledge of the equipment and increase the cost of the system, but well worth it.
So your Uncle removed the waste from the site then?
Seriously, there have been plumbers fined for old radiators in there vans without a license.
If deemed scrap on site you need a waste license to remove.
You shouldn't be looking at the equipment you should be looking at the company and the specification of each job.
Each company should be trained on there preferred kit and most kit does a similar job when it comes to the basics.
Choose the company you feel most comfortable with not necessarily the cheapest.
Your saying SPC is better than I Premier I guess?
Well never really used an SPC but I doubt it's something you would use from a 4 zone domestic right up to a 640 zone hybrid wireless?
As I say I couldn't compare having not used one, but IMO the Premier range is on par with the standard commercial panels you see.
Also it's worth keeping on topic, OP is looking for a suitable replacement for a domestic panel.
