Review: Looking to upgrade Defender is the way to go - The outer box was ripped in several places had to inspect to ensure the equipment was safe, the inner box with the equipment was intact shipping was fast great security camera system, and it was easy to install. Picture quality was great, cable supplied was 60 feet which is more than enough. The overall value for the money is outstanding.
Review: basic system with decent picture quality - This is a basic security system with decent picture quality. I don't rely upon the AI as I haven't found it to be reliable enough. I typically get a bunch of false alerts. With a 4k picture quality, it gives me a decent picture. I can tell when it is my cat in the yard and not the neighbors. This particular system comes with four cameras, but the NVR can hold up to 8 if you want to expand. Running the four cameras continuously, I'm getting a bit more than a week before it overwrites. The system comes with everything you need for set up. The included ethernet cables are 60 ft, but you can extend them up to 300ft without needing a booster. All in all, the system is easy to set up, decent picture quality, and works decently for home security.

### ⭐⭐⭐⭐⭐ Nice starter kit!
*by A***R on July 4, 2025*

I needed something to record the outside area of our workshop and these fit the bill. They feel like they are nice quality and the hard drive space allows for lots of room for video recording. They app is also super nice and defender is a solid company. The best part is the quality of the video. Both day and night vision videos is superb! Everything is sharp and clear and having 4 cameras also you to cover lots of ground!
