Outdoor housing for Telraam Traffic counting camera

I recently found interesting project https://www.telraam.net/ It’s an open source project where a Raspberry Pi with camera counts traffic passing by (pedestrians, bicycles, cars and other heavy vehicles). The device is (as stated by authorts) “mounted on the inside of an upper-floor window with a view over the street. To send the traffic count data straight to the central database, the device needs a continuous Wi-Fi connection to the internet.”
I placed one in my home on the window and it started counting some day after installation.

Next I wanted to install one in my remote location, where I have internet for other IoT purposes. There is no “upper-floor window”, which means I should place my raspberry and camera outside. Here is how I did it…

The housing is simple plasti “junction box”. I drilled hole for the cable gland (IP67, PG7) for supply cable. It will bring 5V inside the box.

Next hole was for the camera:

Camera is not waterproof. I took one small piece of glass from my microscopy equipment (cover glass, really thin and fragile piece of glass!):

This glass will cover the hole for the camera and prevent the elements from penetrating inside the plastic box. Next I placed double side adhesive (I recommend Tesa 4965) around the camera hole and attached the glass.

The glass was finally protected with kapton tape around the edges:

Next, I prepared the cabling (nothing special) – an insert of the micro-usb connector and two wires. The polarity is: red + and black GND.

Camera is fixed with small piece of double sided adhesive tape on the flat cable:

Final piece is 3D printed holder for everything:

This is how it looks when mounted together:

The final step is mounting everything outside:

The 5V power supply is placed inside the house. The voltage inside plastic box is 5V only to keep the installation safe from mains supply.
