Working with larger camera installations can be tricky, but we're presenting here the best practices and some tricks to make everything successful. This applies to Photogrammetry or Bullet-time and it is mostly about connecting over a hundred cameras.
A Raspberry Pi architecture is the way to go when going above 24 cameras. This is how you're going to keep a decent download speed across all of your units. Connect up to 4 cameras per Pi, and all of your Pis to your switches. Avoid daisy-chaining and make sure you're running on a gigabite switch/router. You'll get a slightly performance improvement by using one camera per Raspberry Pi, but the cable and power management will be messier. Over the years, the main issue we've been noticing with larger arrays is the power draw when triggering. If you start losing cameras when you're triggering, simply split your electricity on multiple drops.
If you're experiencing some issues with the software, you can adjust these settings to fit your current installation:
- Image upload timeout: 30 sec
- Ignore extra picture delay: 5 sec
- Download delay (JPG): 600ms
- Download delay (RAW): 1.5 sec
