It is fairly cheap option to have some local storage although it won’t have a great deal of time. Day or two. But for cloud storage that is perfect as it can handle then brief internet outages without losing any video. Just might be delayed.

I thought about installing it in our commercial cameras by default. Had a client get their NVR stolen and having local camera storage would have given them two days of recorded video. Was certain it was and inside job or past worker so it could have been effective.
