Sub £50 IR enabled security camera
Description
This is V2 of the other camera I designed. I've left lots of room inside the case, as some people will be using different SBC's/might want to add a battery as a form of UPS. This version utilises an ESP32-cam to provide the colour image, whilst the IR sensor that goes to the Pi provides a high resolution IR image. What you will need: Pi Zero (preferably W), currently £15 at pi-hut: https://thepihut.com/products/raspberry-pi-zero-w ESP32-Cam £10: https://www.ebay.co.uk/itm/203826423743?hash=item2f750067bf:g:IzoAAOSweFxiAqzd&amdata=enc%3AAQAIAAAA4CEt9tvh9vvX%2F5qI6zbjapQCoE2gKebO01iE%2Fu2zb97SLtT9La59pOhftSPOTUfxB4AF4%2Fp1GjV2Q45661LBzVHH6H2R9dU3xgkI8Kx%2FBt7sO975a5wxmONY1oBrINjCRwZtXYMWscLFuQVNcXTqGaADFjnPncdUfDCbqeye9%2B4ieDlRw4MoxhXL7QzApMpLrVrT%2BpqjvUzsip7V%2F66cgMGKU0Qk5UiZsie5DSRCyhMbNH2AFFawISN5JTB16PyR62iGAAJ%2BmfljERn5wPgQHIc8f%2FTUiG2nDEwoYt2zxtaZ%7Ctkp%3ABFBM7ubTqIxi SD Card £10: https://www.ebay.co.uk/itm/265543046884?epid=223140741&hash=item3dd39956e4:g:qtYAAOSw2uViBP7F&amdata=enc%3AAQAIAAAAwJQ31nRDkoN4DQqf6V6FAWEiKPE2wbxaznBDBh7iTFyIgkmt4R8r6d7NZ%2Fvntz0%2B3gSm01V0HEnsWqyTsxQxWNguBJIC6MW4xrGT3vVKzbI75VDMpnX3NI2vrkrXiNeBSPvfnKaj4svJy5PQc%2FxUe%2BaaPxDBK1HJtm1jGhe%2FQwEzV2F3X%2FKsZ%2BdSz%2BFlvsjUuPKOUGlXM5XExEphreJ%2BQl24BcEqVpBFT75aCYx5m73n4n6NT8KF8s9LFykQRlByTA%3D%3D%7Ctkp%3ABlBMUNy31qiMYg IR sensor at £15: https://www.ebay.co.uk/itm/353947229227?hash=item5268e61c2b:g:4cEAAOSwDWZiIICY&amdata=enc%3AAQAIAAAA4DDMfJ93Y5ELuhW0QNj4CQpuCi0yLGrLGHUKz%2BSx0TZTCGnxzfRwyikzJYfVPImKJyFmTyJwUkCBY8vX7ocPbT9klY8D3oZcaAgM%2Fbv9%2BwSkeTfGwj%2FNL49QUuB0D55WzpMF4okA%2FBCKYfyYf9lSBOjtJZPptNUKQeZws0XS9j7zgdBMz%2Bb86QTP1jcLXmcpQ7q2%2BPbif7TFqOOZ4XUNmcNmFsZ%2FJJ8myei2RAJANELUSAY7lD3oFBTLLf1ac6rtcU7teAq%2F7jOoT2244QoCDmoG3YrythtNRKUqGCUiCQHN%7Ctkp%3ABFBMwrDeqIxi In terms of assembly, I used an ESP32-cam case: https://www.thingiverse.com/thing:4192843 Pi Zero case: https://www.thingiverse.com/thing:1165227 Then for the sensor, I only attached one of them (the left hand one) as I'd heard that using both can burn out the 3.3v rail on the CSI connector. Then, I super glued the sensor to the ESP32 case. At this stage test fit the components to make sure they line up with the holes. I've deliberately left some room, as some people will have different means of powering the units, but I'd recommend a micro-USB splitter into the case; that, or just solder onto the on board connectors if you're feeling bold. Now that you've test fitted the components, it's time to sort mounting out. Again, I've left holes for mounting out of the design, as mine needed to be on the right-hand side. Here's the ball and socket mount I used: https://www.thingiverse.com/thing:67911 Now, glue the small cylinder piece to the ESP32-Cam case. After that, seal up the unit, and use hot glue to ensure that any gaps (which hopefully there shouldn't be any) are plugged, and will stop the weather, and bugs from getting inside. On the software side of things, I'm using a Docker instance of MotionEye as my NVR/VMS, and then on the Pi, I'm using Cam2Web (https://github.com/cvsandbox/cam2web) And on the ESP32, I'm using (https://github.com/BugerDread/esp32-mjpeg-ipcam) The IR sensor is set to 1080p/30fps, and the ESP is set to 800x600/25fps, as the Pi is able to push much more detail reliably over the network, and also does most of the heavy lifting in terms of detail. The purpose of the colour sensor is just to determine clothing colour/redundancy.
