## Customer Reviews

### ⭐⭐⭐⭐⭐ Working but ...
*by D***U on April 23, 2021*

Thank goodness mine is working but you have to sync manually by holding the button down(10 secs.) on the cameras until it flashes amber to add them. Had to turn off night vision for better images using the built-in spotlight. It can be a hit or miss if you buy refurbished or maybe just incorrect configuration. Sometimes app will not find the hub/camera if you have VPN on your mobile device. It has to be turned off.Update: Bought an endurance 256GB Micro SD card, you can now view the videos from the app if you are at home. Set to save on the card and got rid of my subscription. You will not get the fancier options like activity zones and intelligent recognition but still works fine. It will probably hold thousands of hours of recording before it gets full then will replace the oldest. Downside is you can only access the recordings on the SD card if you are on the same wireless network but the cloud recording still works and is good for seven days for free. Overall a very good investment.

### ⭐⭐⭐⭐⭐ Great setup
*by N***A on June 17, 2021*

Setup was nice cameras where super clear but refurb. Unit has bad battery and instead of swapping the battery they returned the whole unit... Just but new to begin with..

### ⭐ Waste of money
*by F***I on May 16, 2025*

They have great quality videos when they work! Most of the time they need reset or restart …terrible experience overall.not reliable!
