Ideal Sights for Testing/Recording?

I really like Bradley Phillips' accuracy test videos, and I'd like a sight similar to his, that's both accurate enough to test precision/accuracy at 100ish feet and can either work well with a recording device or has recording capabilities built in. Any recommendations for something I can get in the States? Picatinny compatibility is a must, but something that could also be mounted to other types of rails would be nice.
