Run

Run Manually

Run Automatically

Run as deamon:

• sudo systemctl start survillancecam.service

How it works

• Take a Photo
• Normaize Image
• Compare last two normalized images
• If motion is detected, Upload image to FTP server

Performance

Raspberry Zero W

• Better take a Raspberry Pi 4 or better
• Take a photo and process it: 8.4 sec

History

• Set time out to 1: 9 sec / image
• Reducing blur: 14 sec / image
• Optimize normalization, reduce colorspace, use faster image format: 23 seconds / image
• Reduce Image size, One complete run takes 23 seconds / image. This mean 2 images per minute.
• Some optimizations: 75 seconds /image
• First try, full image resolution: 90 sec / image

Details

Raspberry Zero W

• take photo: 5.8 sec 0.7 sec
• normalize: 14.7 sec 5.4 sec
• detect motion: 2.8 sec
