Overall

Clear video. Audio is subpar. The app closes down during playback. Would like to upgrade Defender product next time. Good value, however.

Dependable system

This product is an improvement over my first defender system. Easy to install, and easy to view on my smart phone.

Can't connect to a real person

Bought a four camera eight port system, thinking I could add extra cameras later, Cant buy extra cameras. Defender lost a customer. I'll be upgrading with a different company that will sell extra cameras.
