Recommendations for camera setup (stored and streaming video)

The codec should be h.264 encoded.

The recommended frame rate is 30 fps. (It should not be less than 5 fps.)

The recommended encoder bitrate is 3 Mbps. (It should not be less than 1.5 Mbps.)

Frame Rate vs. Frame Resolution – If the encoder bitrate is a constraint, we recommend favoring a higher frame resolution over a higher frame rate for better face search results. This ensures that Amazon Rekognition gets the best quality frame within the allocated bitrate. However, there is a downside to this. Because of the low frame rate, the camera misses fast motion in a scene. It's important to understand the trade-offs between these two parameters for a given setup. For example, if the maximum possible bitrate is 1.5 Mbps, a camera can capture 1080p at 5 fps or 720p at 15 fps. The choice between the two is application dependent, as long as the recommended face resolution of 50 x 50 pixels is met.
