Are any of you using security cameras at home or work? For your own use, not selling or installing.

I have a couple of Ubiquiti cameras and their DVR, but not happy with it. Cameras used to have audio, but that quit, and the DVR isn't recording. Some of this happened after I poked around with a firmware update, etc.. And I never did get it so I could remote access them. They've been up for several years, and thought I would look into something different.

Would like a camera that records on an SD card so I don't have to mess with a DVR. IP camera with good resolution, remote access. Audio would be nice, but not a deal breaker. I want to stay away from subscription services, if possible (Nest, Ring??), but again, not a deal breaker if that is the way to do it.

Any suggestions?

Thank you.
Jim
