I'm about to try out some IP cameras for my future system and since the power supply was not included with them I'm now at a loss.
I am a complete noob when it comes to the electrical part, so I'm hoping to find some insight how it works. When needed I can provide Model type and/or pictures.
There isn't much information regarding power supply for the camera beside the specific line: “DC 12V/500mA”
So my main question would be, what power supply really works – especially what (V or mA) may be higher or lower so it would still work AND I'm also interested what values would damage my camera? For example in a local store I was told that a 12V/1500mA power supplies would work as well, is that correct?
What effects would what values have on the circuit? Is it alright to buy some cheep ones from amazon which simply state these values? There will be about a hand full of cameras installed in the near future, so would it be wise to get some sort of central power supply? Can anybody recommend me anything?
I hope that I've come to the right section here and maybe someone could give me some basic technical insight and an answer to my main question. Please excuse if I got something wrong, it's my first time here.
Thanks in advance!
