I'd also keep an eye on the Rubik Pi 3 as it looks specifically designed to compete with the Pi 5 + AI kit and should provide a faster, cheaper, more efficient option. They're only just starting to ship and no support in Frigate yet, so just something to consider if you're not in a hurry to build a system.
