VW SWB Transporter 100ps. Very nice van but only average 33 mpg. Due to adblue the diesel tank is 15 litres smaller so only do 350/380 out of a tank. Nearly 1.5 years old and only put 15k on it from new.
I don't know these panels, But why can't you scroll back through the event log to see whats it shows prior to power outage and when the engineer arrives.
We have done this on a monitored site and had to tell the arc which cameras had the horns. We had 6 cameras in a rectangle car compound with a horn on every other camera.
If we have issues we phone HIK direct now as they have a local number and based in berkshire.
We have fited some of these with the 150m IR leds and I was impressed with the night vision.
We fit loads of hikvision and they picture quality is good. Fitted the 4 and 8 poe version and also the a 32 channel nvr where you need to supply your own poe switches.
