Yes that was the point not graded , it will work absolutely fine , the others are just used to be proffesional lol
But you would be surprised what you find in proffesional installs
I would definitely put the sound in
Assuming your not grade 3 bank or something
Double up the strobe and sounder, and ignore the tamper if you don't need it, but your wrong on power the plus and minus is for an output so it won't do you know good power the Pir and sounder together, that will mean sounder is always on
You need two cores minimum, then two more if you want the tamper used
1. Got any bouncers?
2. Don't worry about child care any online company will do it for a fee
3. Money and headache
Aim for CCTV and alarms as a side earner , commercial CCTV and in general CCTV is a better earner
But definitely worth looking at other equipment aside from hik , unless you prefer to learn nothing else
House bashers perspective of course
You near Liverpool? Have a look at the list on this site, otherwise someone local , one problem is some companies want contracts or not interested so you need maybe a house basher local to you , must be someone advertising locally , although not all may use galaxy
Better to go seperate
Some intruder alarms can send snapshots
Better to have 8core imo
Run a cat5 to every CCTV point next to the rg59 it will prove useful later and it's cheap enough to do
And where ever you might want a camera later run an cat5 there to , you might only want three cameras now but 10 in the future might be nice
