This is an incredible system. The image quality is great, set up was simple and its working extremely well for us! The system comes complete with everything needed and all looks to be very high quality product. We are thrilled with this 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.

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

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

The cat5 cables that came with the equipment is garbage and is not connectorized for 568A or B standard.

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

Camera system was easy to set up, program, and utilize. Provided added security with good HD video recordables.

I installed it over a week and have been please with it . The system was easy to install and setup . Will add cameras at a later time .

That's audio camera

We've used Defender systems for many years and run a number of their systems and devices. We recently updated to the Defender 4K Sentinel POE system and pleased to have done so! The setup was simple, well documented, great image quality, ease of updates and love the functionality coupled with the Defender Empower App, that we use on both IOS and Android devices.
