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.

Fantastic security system for monitoring our manufacturing facility. Installation was easy and the cameras have a simple, yet robust UI. Would recommend to anyone looking for a simple yet effective security system.
I would recommend this to a friend!

Great quality 4k camera system

Bought this system for my garage area and Alley. I had the last model for my house and was pretty happy with it, great picture, good value, nice iphone app.
This new model has all the things I liked about the last model, but upgraded software on the NVR box. Its easier to setup, the interface looks sleeker, and setup process was faster. Most of the time I check the alerts and views on my iphone app, and it can show you all the motion alerts with a nice little link that takes you to the right spot in your recording, from there you can watch, skip back or forward to get more context.
I like the look of the cameras, they feel pretty sturdy, and you can set them up to have a security light type response, or go more stealth with just the infrared option. Setting that up took a bit of poking around in the menu, but now that its setup, I have it setup differently per camera, which is nice. I like that I can add up to 4 additional cameras if I need later, 4 was enough for my needs now though.
I also really like the POE format, power of ethernet, which means one cable sends power and picture/sound signals, no need for extra wires, and you can use most any cat5 type ethernet cable (this comes in handy if you need to setup outlet plates and a few dis-connectable wires). Another bonus to having this wired system is its harder for thieves to use wireless camera disrupters to block signals.
II was already able to get footage right off my phone for a neighbor when someone broke into their adjacent property to send to the police.

Excellent Security Camera System

Excellent Security Camera System to protect your home. I have been a long time Defender systems user and love them. These model specifically has wide angle cameras and great night vision capabilities. the sensors work great and picks up movements immediately. If you are using for inside the home, i would recommend to turn off the lights for night vision. Access from app works nice and very quick/easy to setup. Audio feed, although works only from one camera at a time, is a good feature to have.

Overall is ok.

Overall is a good system but it’s a bit cheap material and they can make it better. Included cables could be longer.

Super easy to install, and love the crisp picture. Only quip I had is that 60’ runs are tight when going to opposite ends of the house, 80’ cable runs would have been much better as I had to extend 2 of my camera runs.

You changed your hookup technology, this new system can't be run in parallel with my previous Defender system. That's of little consequence, I'll run them side by side, but it wouldn't have been nice to have had a certain consistency.
Regardless, I'm a kern patron of your technology, and will be buying more as my business grows.
