Thinking of doing similar. Most poe nvrs need 240v supply, i think i'd use a 12v nvr or dvr without poe and just power the cameras at 12v, one less inefficient power conversion. when i worked on a few sites that were being surveyed for wind generating sites the wind measurement devices (lidar and ultrasonic anemometers with data logging and a satellite modem) were powered from banks of gel batteries in a bund charged from a few solar panels. The draw at 12v was around 2a and these things were left there for months. I would charge a hefty maintenance fee though.

Is the link light coming on? Can you access its web page? ping it? discover it with the manufacturers ip config software? is there a hard reset procedure? what kind of camera is it? why is my leg wet? is tesco still hiring?

Temperature compensation? you are asking a load of questions over a number of posts would it not be easier to lump them into one post?

Quite often burglars are drug users. The purpose of a strobe is if the burglar has dropped an e recently and they see a strobe light they will stop what they are doing and start dancing like a loon. The strobe can keep them dancing for up to 12 hours, which is almost long enough for police to attend and catch them. If they can be bothered.

So pre 1971? Quality.

this was the actual fire panel in service at a nursing home last time I was there in 2012. the nurse call wasn't much better.

D1ts are good for the price, d5ts are just damn good. Tvi is not as forgiving as analogue, dvrs are solid. Only 1 alarm receiver ip though so if your monitoring arc switch regularly its a no go. Cable faults putting 12v down the video line blow the input on the dvr.

Apologies if you know this already but udl password isn't necessarily the same as eng etc codes

Does a british firm count? A lot are here with me.
