I purchased this for my home and it is easy to set up and install defender makes good quality products. The app is easy to use and everything is easy to configure. You just need to be able to know how to install it and or hire a professional.

Love these cameras. The set up is super easy and straight forward. The hardest part of it all is running the wires lol other than that you connect them and scan the QR code to download an app to your phone. The hardware is set up to detect the cameras once plugged in all you have to do is adjust time and settings. It’s fairly easy to do yourself. You do need internet and power for them to display. Just in case anyone is wondering. Other than that I am very happy with them and the way the display.

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 disconnectable 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.

I have several Defender camera systems because they are quality made and user friendly. The Defender 4K Sentinel system is no exception. Putting the system on the monitor and online took less than 30 minutes. If I can do that, anyone can. Running the lines, of course, can take more time depending on your set up. The picture is crystal clear , the color is great and the human detection was effective, even my cat didn't set it off. The audio pickup on recordings is good and when detecting movement, using the option of flashing red and blue light or white light is a nice touch to alert people they are being watched. Over the years Defenders customer support has been greatly appreciated with their reliability and perseverance in helping me with a variety of issues. Phil

This was an upgrade from a BNC-wired security camera, and I must say I have definitely no regrets upgrading to a PoE system. Whereas my previous security system was only video data, the Sentinel 4K also recorded the audio -- making it more useful when needed. The casing for the cameras were a metal alloy, whereas my previous system was made of plastic, so I feel more comfortable with the durability of this system in the Texas weather. The spotlight/flashing lights feature is an added bonus, and when needed, I can imagine the lights surprise sending instruders running. Because our house is almost 5,000 sq ft, the included 60-ft of ethernet cables were not enough on 2 of the cameras that were installed unto the farthest end of the house. However, the advantage of having a PoE is that I can use my spare ethernet cables lying around in my office and connect them to the included 60-ft cables to make a longer run; I just had to buy an ethernet/RJ45 coupler that supported PoE, which was relatively inexpensive. I was very surprised by the plug-and-play ease of installation, and after following the setup wizard, I was up and running in no time. Overall, I would recommend this Sentinel 4K security system, especially if you're in the older BNC-wired 1080p systems. Performance, value, and quality wise, this was a needed upgrade for me!
