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

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

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 .

The video quality on this system is great and setup is a breeze. Motion detection is somewhat hit-and-miss so as part of a security system you would still want more precise intrusion sensors, however, this works great to provide recordings of past/event activity for future reference.

My overall impression of the 8 Channel 4K Sentinel NVR is very good. The system came well packaged with each camera packaged in it's own box. It was a breeze to setup with the cameras truly being plug and play. The NVR and accompanying app were configured within 10 minutes of unboxing. By far the most difficulty is running your cables to your camera locations. Take your time and plan where you'd like your cameras and the routes you have access to for the cable runs! The image quality of the cameras is fantastic and far surpasses the wireless cameras I used previously. The accompanying app is intuitive and easy to use. I was surprised at how little bandwidth this system uses. There are many options which can be configured around motion detection, notifications and schedules. Setting up and using this system has been a great experience and has provided a lot of value in a nice DIY package.

Installed in a day and very happy with the video quality. I don't use any detections, it's something I'm still on the fence about but I'll probably work on setting it up soon. Also, there is a way to use the app on the computer though using the software Bluestacks, it's a phone emulator for your computer and it's free.

My husband and I purchased the 16 POE camera set and have been enjoying the many options. The ease of installation was the first thing we noticed. I especially like the following: audio recording, footage in vivid color, white spot light, sharing the NVR, and the ability to view the detection page or my notifications prior to viewing playback. I am an old defender customer. When I listed my house to sell that was one of the features asked if it was staying. This is my second set since selling my previous house. The 4K color is great (clear and vivid). My preference is the wired set. I would definitely recommend this product to others.

The Sentinel system is exactly what I have been looking for! We loved the easy set up with 1 cable for footage and power! We didn't have to worry about power adapters or power bars. The great 4k resolution with motion detection is awesome! I have 1 camera in the backyard to check what critters that may be running by after the winter thaw!

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.

I purchased a couple months back and I got to tell you it's a great product. It's relatively user friendly. The only downside is customer service which I understand and respect and hopefully that will change the staff is good at getting back to you ASAP when confronted with an issue..
