My first post and I am asking for advice. I have a few bird & small mammal boxes in my garden with CV cameras. I have tried routing the feed via CV cables back to the house which is rather clumsy. I have also tried combining them and routing them through a balun & Cat5e cables but I am experiencing corrosion on the Cat5e contacts. So I thought that a Pi Zero W and camera module in each box transmitting to a wireless hub in the garden which was connected to a Cat5e router in the house might solve the problem. I appreciate that I would need to feed a 5v supply to each box which I can do from a supply in the garden. I am not clear as to what modules I would need to purchase for each box.
