[QUOTE="pontiend, post: 1070009, member: 275842"] I have four cameras down the garden.One on the end of a 30 meter lan cable.Never any problems with that one.Three WiFi not so good.Problems keep cropping up. They are all about 25 meters away.I think that one of the problems is that the weather gets at the power connectors..They are not working now, I have reset the router,disabled UPNP. I am going to hard wire them. I have purchased two 30 meter and one 40 meter cables.Also a four port POE injector.Not being up to speed with POE injectors I do not know what voltage and ampage I would need to inject.The first one that I will do is the 40 metet cable the camera is about 35 meters .For that I know that I can just plug its 12 volt one amp power supply in.However the next one will be one of the 30 meter ones.I will eventually get around to fitting the other 30 meter one up too.The question is what voltage and ampage would I need for two cameras then eventually three.I assume that more cameras would need more amps.The power plugs are all 12 v 1 amp. Edit all four will be on the injector eventually. [/QUOTE]
