You enter eng , remove the keypad , wire up new one and then add new one , system should see no keypad
I assume you have no app system so can't do it from virtual keypad
Or just add new one as keypad 2 and delete keypad 1 , don't really make much difference for you
Or you know who to go see right ?
Some of the keypads had touch sensitivity problems , these are all usually exchanged via the supplier , hkc can't tell you which ones are at fault , and over time the problem gets worse where they keypad starts pressing its own buttons as such
If you bought without warranties unlikely you can exchange and will just have to hope it's just the Illumination bit
Unless you have some knowledge for this it will be difficult.
I would remove the fuse again
You need logically check for electrical power ,
How do you know the mains power is not disconnected somewhere? After inserting fuse that would be your first check , by maybe using a mains tester.
Actually forget that, you're better off with the dahu bell, hikvision doorbell which has on they do various but I'm not sure what you mean by single channel playback as the hic and other recorders do playback more than one channel
I assume you have a limited budget which is fair enough
I think any , but have to connect it manually on the NVR on spare channel using it's IP address etc
Hik connect as seperate unit for the call ring features
Hate hik lol
Although bell can be reconnected within a min or two of you skilled enough
I would have let the old panel hand some how cut the plastic or something got the new back plates in and powered up may odd disconnect but it would have been quick
15min ringing you letting the kettle boil
Depends how it's all wired tho, if your going to take time you can disconnect and send power to it via a battery , otherwise as above I guess
Keep windows and doors closed that way it doesn't bother you lol
