Just join crimp , solder and extend cables etc
You could bury them in wall and put a face plate on top after
I would open the plaster up more towards ceiling and fit panel higher up if possible then joins can be inside panel
Do you have a better picture?
Dude
Simple process for you
Swap both keypads round
If keypad one works in position 2 atleast you know for sure to an extent the cable power and coms is good
Then it has to be addressing and programming or the keypad itself
No know jack about them , everyone here has used them plenty
But fastening cables depends on where and how , I still see steel cables above voids , metal trunking in communial walk ways or plastic with d clips or other fixings
As the gorillas here mention , high cameras for overview but only see tops of heads
You need some cameras lower to capture the face and better detail
Don't worry about vandalism , if someone breaks it just buy a new one lol
Houses rarely have there cameras broken by thieves I would say neighbours break them more often lol
Out of curiosity
Swap the strobe- and bell- wires at the panel only , do same test you said you did and what is the difference?
As swb said maybe tampers not closed or some panels require a resistor on the tamper circuit , I don't know this panel either
Ps you sure it's not aG6 bellbox?
Where you panel?
eBay?
amazon?
Think they have returns policy if bits were missing , maybe it was used panel , although resistors are cheap and programming them out is easier
Nah I have messed up sleep pattern, plus one of kids was not well so night shift
But generally poor sleeping habits , haven't done Oncall for anything for years never did that for intruder , only for optical transmission stuff was more of a paid tea break , leave Oncall for the chimps dude
