This is not really a letterbox, but I want it to look like one. Here's the existing letterbox:
But there are a number of problems. There's not really much room in the letterbox now and I wish to install a much larger camera that's about 5" long and 3" diameter. Also, heavy rain does get on the lenses. The letterbox is tatty and I'll make a new one.
Even though nobody has noticed the holes in the side, I'd rather have a big slot that goes around maybe three sides of the box and have the cameras pointing through the side slots and have a rain shield above them.
One problem is that if the cameras are level with the main letter slot they will be in the way.
I'd like to think of some excuse for having holes or slots in the side. Currently I'm thinking of having a simple box with a flat roof a couple of inches above it. There would then be a slot all the way around. I can have a partition on each side of the actual letter slot so it's obvious where the letters are to go. And a support in each corner to hold the roof up.
Unless anyone has any better brilliant ideas, as I know someone will!
