![]() ![]() The footage can be accessed from anywhere with an internet connection.Ī: Typically, the reset process involves holding down a reset button on the camera or using the smartphone app. Most seem to agree that the image quality is really good and they also like how easy it is to use with the Defender app.Ī: The Defender Sentinel 4K PoE Security Camera System is powered using Power over Ethernet from the NVR.Ī: You can access the footage through the smartphone app or web browser, which allows for remote viewing. This is a fairly new system when I write this but there are a few reviews on Amazon and it seems like people who bought it are happy with it. This surveillance system works without internet however if you want to use the app for remote viewing and get notifications you need to connect the NVR to your router. The NVR comes with a pre-installed 1TB hard drive and according to defender it should give about 400 hours of recordings before it starts to overwrite the old recordings. When there is no detection they will use Infrared lights for normal black and white night vision. And you can set the cameras to only turn on the spotlight when motion is detected. Since they have built-in spotlights they can record in full color at night. And they have a working temperature between -40 ☏ ~ 122 ☏.Īnd like most modern cameras they support AI human detection, which means they can tell the difference between a human and other moving objects. The cameras are made of metal with an IP66 rating so you can place them outdoors in the rain. So this Defender Sentinel 4K system comes with 8 cameras that records in 4K at a maximum of 15fps. Installation is so much easier using POE. And that’s why POE security systems are so popular. If you are not familiar with POE (Power Over Ethernet} it basically means you only need one Ethernet cable between the camera and the NVR for power, data and audio.
