Security Cameras

So far the cameras and NVR are working great. Much better than my 2K system.

Good Luck

The 2 year warranty is not legit. Be aware if you have an issue they will say you only have a 1 year warranty, good camera system but poor warranty claim took 2 weeks of steps for them to claim it's out of warranty, but I still have 5 months of the warranty left.

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.

Defender 4K Sentinel

I have been using this sentinel camera set up for about a month now. The installation of the cameras was easy to do. It did take some time to hide all the wires, which is to be expected. The NVR was very simple to set up and I did it without any problems. The picture quality is amazing on a 4K tv. I had no issues with setting the app up either. The steps are very well layed out. The quality of the picture during the day is absolutely beautiful. There is an option to record with black and white, or colour, or in smart mode. It’s crazy how in smart mode when motion is detected at night, the scene gets lit up in colour and it is just as good as in the daytime. This was a nice surprise. For most of the camers I kept the sensitivity level on low. When turned up it will pick up rain and you will get a lot of notifications. Turning down the sensitivity helped with this issue. The cameras that are semi protected under an eve also help reduce false alerts. Just something to think about when doing the camera placement. I really like the app. It’s easy to find and play your motion alerts. It has a playback feature that you can watch all your alerts for each camera. After playing the first video, it jumps to the next one automatically. We’ve had problems with bears in our neighborhood, so I use the playback feature to view captured motion alerts that happen at night. Overall I have had a good experience with the defender 4K Sentinel security system. I highly recommend this system if you want or need a good quality system with the best quality of picture. It’s nice that the price doesn’t break the bank too!

RUN AWAY! Low quality, Breaks often!

I would give this ZERO stars, but the customer service response is worth at least the ONE star. This system is pure trash. It works so haphazardly. I've had each and every camera replaced since having this system installed. Even after replacing the cameras, the replacements went out as well. Not all cameras went out at the same time, but they went out in days or sometimes weeks of each other which resulted in the installer having to continuously return, resulting in service fees. We had some of the cameras replaced 4 times that were in the same spot. During the first year the customer service had no problem sending the replacements, but having to have the installer repeatedly return was a headache. They run you through a lot of steps because the camera's are continuously offline before they send the replacements. Once year 2 hit, they didn't honor the 2 year warranty they had with Sam's, but with some negotiation the sent the replacements. Mind you those replacements didn't last 3 months. The app suck big time. It thinks everything is a person. The alerts are insane and so constant that you go numb to them. Some things it thinks are humans are your grill, the patio umbrella, a downspout, and trees amongst a variety of other things. I could go on about how unreliable and horrible this system is, but I think you get the point on this low quality system.
