Just to add to the public search although not completely your case but
Upgrade upgrade upgrade , even those paying monthly contracts paying far to much to maintain rubbish (not everything but most is rubbish) and it's not the installer / maintainers fault no one wants to pay.....
Technology has moved on
Your hardcore
So hiwatch is the DIY market for hik
But will debenhams give you any after sales support , pay a little more and buy from a security dealer
Compatibility is normally done via onvif , if all IP stuff, if it's all analogue then hik uses tvi I think and some of there cheaper stuff might have switchable outputs going from normal video to and and tvi and so on
But if you renovating good time to scrap what you have , as above replace DVR to hybrid type which accepts some analogue and ip
So you like the orisec keypads yeah?
Come on be serious it's not a bad panel , not many firmware issues like texe eh
But hkc is better....
Although I still working on hkc to convince myself to remove my gd48 at home , wired it's hardcore
I thought it will work fine
Only fibs that don't are some texecom ones , something about them writing to the fob Inna certain condition , can never remember what though
It's better than some other stuff lol
Visonic , pyronix , orisec
Wired ion not bad , with few adjustments 2way it's better than the G2 that everyone lashes in lol
Why is alarm going off? Battery back up should stop that, I didn't think veritas had power alarm setting
Pay attention, why is alarm triggering on a short power cut
