You assumed zone 4 is patio doors by searching online
A zone could be any device in any zone
Ascertain how many sensors you have trigger them one at a time on walk test and tick off each one , you may find magnetic sensors on doors in the frames or on the surface , to try and narrow down what and where your looking for it
Got no idea , I was just commenting on another comment ,
Reality check you have all the answers above so need to make choices choices , always means spending money lol
I meant the device not the aerial , some devices work off a buss like the webway and so , and you can mount it away from the panel but these cards you can't
It's a shame allot of these products can't be mounted further away as you can't extend the data connection
Maybe everyone has to switch back to dial capture and all is well
You think hikvision will start charging some time soon?
Would be good if they did lol
Would you start fitting the agility when they start having to pay?
Blue line is probably what the dudes will recommend but can you install any shocks on the windows or does dog headbutt door?
Why not just omit ,on a newer panel this would all be easier to do , reality you need to scrap that panel even if you think it's good
