Review Summary

Rated 3 out of 5

We've only had the camera

We've only had the camera system installed for two weeks, but so far, once we figured out how to configure it properly, (ie. using the NVR set up for motion zones vs the phone app), it works great. The two 10TB hard drives are supposed to last for about 65 days, but that is obviously yet to be seen. Thus, in response to your review request, I'll only give it 3 stars (an average review. ) The only major drawback I've noticed so far, is when I turn off the monitor connected to the NVR or do certain other things with the NVR, it requires a new sign-in. Since we don't have a keyboard on the NVR, that can become cumbersome. Is there a way to connect a keyboard to the NVR?

Upgraded from 2TB drive to 4TB

Installation was easy and the drive started working as soon as I powered up the NVR. It's been a few weeks and everything is working perfectly. Now I get seven days of 24-7 high-definition recording on six 4K cameras.
