TEC cctv

I am unfamiliar with them and dont feel comfortable selling something Im new to

There is no place to put a remote dvr as the area doesnt have a secure place to put one. Also, Im not using I.P.

how many cameras will you be using. and what sort of image are you looking to get from the cameras. wired is best. do you have no way at all getting cable to the area. I need 4 to 5 remote cameras. I don't need a High Def quality picture but I'd like it as good as I can get it.

Here's my deal... I need to use wireless cameras at a location that will be outdoors and have power. They will be mounted about 150 yards away from the building where the dvr is housed. What would be a good option for me to look into beside wireless IP cameras? Running conduit to the locations is an option Im trying to avoid.
