When to know what to use? And what is the difference between a 1 amp and 2 amp power adapter? this is from the manual from my camera My planned setup is for 3 outdoor bullet type cameras at a maximum distance of 50m from the dvr. TIA!

yet one of the technicians from our local shops is saying they had no problems with 50m cables and the cameras run despite the voltage drop. i don't even know what to think anymore. i know under volting power tools or any equipment that need a lot of power would definitely cause damage to them but does this hold true with cctv cameras that draws only 12v?

very difficult to run a 220V line as it is an outdoor cam. any professionals in the field can confirm the voltage drop at 50m is that significant that is harmful to the cctv camera? Hi. 50m is not a problem for 12v ....... Does that no problem It's the amps that plays the part ........ 12v 2amp is not a problem for your half amp cameras ........ You can run two cameras that distance with no problems specifically, what type of gauge (i don't know if that is the right term to use) of wire should i be using to avoid voltage drop at a distance of 50 meters? i assume i would need a special type of wiring for this purpose? people are suggesting to get the correct AWG for this. i don't have a clue what they are talking about.

thank you for the input, the camera is a fixed focus day/night and doesn't have PTZ or any fancy features for that matter. so would it be safe to say that 1 Amp will do just fine even at a distance of 50m?

is battery backup for dvr's a must? i am just concerned because we have frequent black outs in our area. or would avr's just be fine? tia!

if that is the case then another problem would be lightning strikes. how the best way to minimize the damage it may cause to our systems?

which is more damaging? power loss or bad line voltage?

Was just wondering, would power loss damage your dvr? In 20 years, I have never had a computer get damaged due to power loss.

hmmm, thanks for the input guys. what about avr's? it can do the things you mentioned except prevent power loss. is battery backup totally necessary?

my concern is will it get damaged due to frequent power loss?
