- These counts are for device software 2.1.4 with 1080p cameras, person, face, and vehicle recognition on, and the default 10 analyses per second. At these counts, live video stays smooth even with people in view on every camera.
- Ryzen 5 PRO 4650G and Mac (Apple M2) are measured. The other PCs are estimates based on CPU performance (PassMark).
- A graphics card lets the same PC handle more cameras. Select the graphics card in AI processor in Settings > Performance (device software 2.1.4 or later).
- 4K cameras, a higher analysis rate, or other programs running on the device reduce the number of cameras it can handle.
- For more cameras than the table shows, split them across several devices.
