Firstly, as I'm new here my apologies if this is in the wrong section. Secondly, hello everyone Now, to the point. I am currently looking into purchasing some wireless cameras to record on a small business site. They are mostly going to be used to spot intruders rather than having the video used as evidence against them so perfect clarity is not as important as it could be to me, also I have no need for audio recording. With this in mind I am wanting to place 4 wireless cameras within a 150m radius and they will be required to transmit through thin metal plates and some brick work to a secure DVR. Night vision would be a plus side, however I do not require anything too great as I have said, it is mostly to detour and spot any would be intruders. Could anyone please advise me on what kind of system may be needed and where I might purchase it online? I am currently looking into it myself though I am feeling somewhat overwhelmed by the amount of CCTV products currently on the market. Any help is appreciated, thanks.
