Nice system

The camera install was the hardest part for me. So far the system works great. I like all the features it has and have just started to connect it to the internet.

Better cameras. No subscriptions.

These cameras are just what I was looking for. I had wifi cameras which expensive enough. Then you have to add monthly subscription charges. It seems like it was a ripoff, which I'm glad to get rid of.

just an avearge..

I did not know that it will need a screen to do all the configuration and settings. that is a drawback. Clarity of picture is not as per my expectations. It can't read the number on my car's number plate parked just in front of my driveway.

Hello Rohit, Thank you for your honest review. The system can be monitored from the app, to set the system and for several configuration options, you will want to connect the NVR to a monitor or TV. Please reach out to our support team, we would be happy to assist you with checking your settings to ensure you get true 4K picture quality. Thank you for choosing Defender to protect what matters most. Amanda M. | Defender Customer Experience Expert

Good value quality cameras but Settings limited.

Good quality camera, easy to install. Design needs more flexibility to position anywhere and see image upright. Also gets a lot of false positive “human detection” even though we turned sensitivity to Low.

Do not buy - junk!

Do not purchase this system. I bought this system approximately 1 year ago and it has already quit working. There is also no support number to call for any issues.

Good enough for the discount

Easy installation, besides crawling around the attic. Plug and play not internet access required unless you want to use the app

Overall

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