Heat Sink Raspi Zero W IR Cut Security Camera Remix

thingiverse

This is a heat sink remix from lenne0815's "RPi Zero Security Camera" from https://www.thingiverse.com/thing:3874164 You can find the stand and other remixes at the original design. This remix adds 5 mm to the main (haupt) part, so that heat sinks on the IR emitters can be included, furthermore the middle (mitte) part has extra air flow channels, and finally the hat/back (kappe) part has a bigger hole for the RPi CPU heat sink and additional extra spaces to allow better and more air circulation within the back housing containing the RPi Zero W, and there is a back version with extra distancers to avoid screws for the RPi. Several RPi Zero W are being used with a fisheye wide angle IR cut camera, handled by the RPi-Cam-Web-Interface running on Raspbian and the Cam interface's internal motion detection enabled, which basically puts a permanent CPU load of around 20% on the system when using Max View 972p25 (4:3) resolution with low latency streaming, motion detection, motion recording, and high quality streaming. So the temperature of the CPU gets around 70°C and the CPU heat sink then is really needed. MotionEyeOs was not an option, because the frame rates and quality were really too low, and additionally the latency was too high. Extra parts used: - 2 bolts with nuts: 5/32 X 1" (~3 mm too long, e.g. 4 X 20mm should be OK) - 1 screw: 6 X 3/8" (or 3 X 10mm) - 2 zip ties: 200 X 2mm By the way Raspbian had kernel panics related to the camera when using the RPi-Cam-Web-Interface, and the following settings worked around it: cat /boot/config.txt - over_voltage=4 force_turbo=1 RPi Cam Control v6.6.13 settings: cat /var/www/uconfig - annotation pi %Y.%M.%D %h:%m.%s %a hflip 0 vflip 0 width 800 video_width 1296 video_height 972 video_buffer 3000 motion_external 0 motion_threshold 200 watchdog_interval 60 watchdog_errors 6 And these were the homeassistant settings for the RPi-Cam-Web-Interface driven security camera: cat ~/.homeassistant/configuration.yaml - \- platform: generic still_image_url: http://my_ip/cam_pic.php stream_source: http://my_ip/cam_pic.php framerate: 25 username: !secret camera_user password: !secret camera_password name: picam5
