Customer Ratings & Reviews

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!

The Defender - AI POWERED Sentinel 4K Ultra HD Wired 8 Channel PoE NVR Security System is an outstanding investment, delivering exceptional value for the price. Its 4K Ultra HD resolution provides nearly four times the clarity of 1080p, ensuring sharp, detailed images with impressive zoom and night vision capabilities. Whether I’m viewing footage on my home network or remotely from my phone, the system offers seamless accessibility. One of its standout features is its AI-powered object detection, which identifies people and vehicles based on their shapes. This intelligent filtering significantly reduces unnecessary alerts—eliminating notifications triggered by animals or shadows—so I only receive relevant security updates. Additionally, the continuous 24/7 recording feature adds another layer of reliability. With its pre-installed 1TB HDD, I can trust that every moment is captured, whether through constant recording or motion-triggered events. Having used an older version of this brand’s security system for over a decade, I decided to upgrade to this latest model—and the image quality and advanced technology have made it well worth the switch. For anyone seeking a high-quality, dependable security camera system, this is an excellent choice, making monitoring my home effortless.

5 STAR HISTORY I have enjoyed our family’s Defender Security Camera system and due to our experience, I recently purchased the Defender - AI POWERED Sentinel 4K Ultra HD Wired 8 Channel PoE NVR Security System, 8 Metal Cameras & 1TB HDD. This system will help me keep an eye on my rental property and help keep them safe. The clarity of the 4K footage is simply breathtaking, capturing every detail with remarkable sharpness—day or night. The user interface is intuitive, making it easy even for those less technically inclined to navigate through recordings or adjust settings. The motion detection is reliable, minimizing false alarms and giving real peace of mind. In short, Defender continues to earn my trust through both innovative technology and a genuinely caring customer service team. It's rare to find a company so committed to their customers' security and satisfaction, and my family and I are grateful to have found them.

Works great. Clear picture. Big upgrade from our older unit and definitely more user friendly on setting up. We used to have a hard time everytime we got a new router. The newer technology systems have all that port forwarding and ip addresses taken care of for you. Only thing I saw that could be improved is the drywall anchors were too small for the screws. But I only needed one mounted on drywall in the garage. Got it about 50% off though so I can't complain.

I was so impressed with the previous Defender camera system I purchased. So I decided to purchase this system for my parents house. The AI system is great because it recognizes humans and will only alert you if there's someone near by. This will cut the random alerts on the mobile app. Since my parents aren't so technology savvy, this feature will only alert them for people being close by and eliminate all the random stuff that passes by. Highly recommend this system who want reliability and peace of mind.

I have been using Defender Security Cameras for over 9 years, and I can confidently say this company is truly excellent. Their cameras use advanced AI technology, which provides crystal-clear images and high-quality video. The customer service has always been outstanding, fast, and reliable. I highly recommend Defender to anyone looking for a trustworthy and professional security camera system.

This was a great upgrade from our original Defender security system. The image quality is great and the night vision on these is a great improvement to what we used to have. Having them being powered by Ethernet is also a great plus. Overall happy with our new system!

Easy use. Great images. Very easy to install. Activate as they are supposed to at all times!

I have been working with Defender for nine years, and it is by far the best company I have ever worked with. I own three stores, and all of them are equipped with Defender cameras. The system I currently use — the AI Powered Sentinel 4K Ultra HD Wired 8 Channel PoE NVR — is one of the best on the market. Defender truly represents the pinnacle of AI technology in security systems. The video quality, reliability, and advanced features are exceptional. Their customer service is outstanding, always professional, and ready to assist. I confidently recommend Defender to anyone looking for a top-tier security solution. This is a company that delivers on its promises.

Great security system, Best Buy price matched so we saved a ton of money, and it was a easy install.

Would be 5 stars however, if you go to do the software update, it renders everything useless and you cannot use the cameras or even get into the dvr to stop it. Just have to unplug and dont update. 2nd, there is no way to put a 60ft section of POE cable onto another, they dont make or include a POE coupler. You can get one on the internet though Not really a bad thing just would be nice. Last but not least, all the QR codes on the packaging do not work. For instance, 1 says to scan code to learn how to instal the waterproof connector. They all just route you to, (in my case, since i am an android user) samsung notes where you'll find nothing but a bunch of meaningless numbers. Overall though, GREAT equipment and dang good, crystal clear high quality video. I wish the user interface, within the dvr, was a bit more user friendly and more simplified though. If you are thinking about getting this, its worth it. Most the stuff I "complained" about up yonder isn't all that bad and i think its a great system so far

These cameras do not swivel and therefore need to be strategic with placement all in all work as intended

I have had it about a month and it works perfectly. The app takes a minute to figure out but once you do it works well. Cameras have a nice picture. Good system.

Excellent camaras. All the features I needed for my security. Image quality is amazing, and installation guide was pretty easy. Application remote connectivity is super-fast.

I had this camera system installed over the weekend and could not be happier with it. The night vision on the camera is in color and crisp. The deterrent red and blue lights are a big help since we live in an area with constant construction, and they help chase away unwanted company. The AI detection helps eliminate the false alarms of detecting passing cars and only alerts when people are near them. In the couple of days we have had he camera up, it has brought me great peace of mind when I'm at work or asleep at night. Highly recommend.

Quick and easy setup. I love the single cable POE connection. My only complaint is that it does not appear to connect to my old Defender Sentinel cameras. I hoped to slowly migrate to the new camera after switching to the new NVR.
