Before anyone currently looking for cameras buys something, spend some time poking around ipcamtalk.com. Those guys can help you avoid buyers’ remorse.
If you’ve never had a security camera system, you’ll likely think a Nest or other WiFi system is great. I did. Then one day, while working in my shop, a pair of people arrived with clear intent to break in. Although my Nest cameras clearly showed their intent, the cameras were completely inadequate to identify them. Worse, that evening, while I was still concerned they may return after dark, every time I opened the app to check what was going on, I’d get the annoying ”pinwheel of bufferring” that had me wondering if it would even open. And of course with those cameras, if your internet goes down, you can’t view your cameras and they aren’t recording.
I decided I wanted a system that would open “right now” and function with or without Internet. I bought a used PC, installed Blue Iris NVR software, and haven’t looked back. Camera image quality is better, and I have complete control over motion detection without any monthly fees.
