Third-party camera compatibility options?

I had an attempted theft of jetskis and wheels off a vehicel in my drive way during the night. Two different cameras/angles one camera was within 10 feet of one of the perps who looked directly at the camera, the other camera within 15 feet but the video quaility is so low, no details of the face could be made out. Out side of the night vision, I like everything else about Xfinity Home. I'm wondering if anybody knows of any 3rd party cameras that are compatible with the system?
