  • Thanks to the camera's powerful 8MP image sensor, you'll experience the difference that 4K resolution makes when it comes to your security, 4K means there are more than 8 million pixels, and that results in sharper video, realistic color representation and superior digital zoom capabilities
  • Limit motion detection notifications with smart motion detection plus, this feature offers the option of either face detection or person and vehicle detection
  • Perfect for front doors and entranceways, face detection will only notify you of motion events when a face has been detected, this prevents motion notifications from people or vehicles simply passing by and not coming towards the camera
  • With person and vehicle detection, this innovative feature, you will only get a push notification whenever a person or vehicle is detected on your property
  • Take an active stance against uninvited guests
  • Built-in speaker and microphone allows for crystal-clear audio functionality, listen-in audio recording will add a whole new dimension to your overall security monitoring, as it can provide additional details (like a voice) should an incident occur
  • Lorex's Safeguard technology is perfect if you have very specific objects or areas that you need to monitor, the feature allows you to set-up to 3 missing areas and 1 left behind area, the missing feature allows you to select important objects of value that you would want to be notified if they are removed from the area, conversely, the left behind feature allows you to select an area to be notified if something is added
  • Camera features our revolutionary Color Night Vision (CNV) technology, which will produce full-color video with the help of external lighting around the camera, CNV also adds a further level of detail (the color of clothes or cars, for example), and increases contrast for easier detection and recognition of people and objects
  • While this camera is suitable for both indoor and outdoor use, it has been especially designed to withstand the harsh impacts of nature, it has an IP67 rating, meaning it can tolerate extreme temperatures ranging from minus 22°F to 140°F (minus 30°C to 60°C), It also has a durable, all-metal housing for added protection
  • Feature-rich system is designed for use with our innovative, hassle-free Lorex Home app, using Lorex Home, you can quickly and easily view your security system remotely from your smartphone or tablet and control smart deterrence features
  • Get faster access to you security system with hands-free voice control, use simple voice commands to activate camera features with Amazon Alexa and Google Assistant, use it with Chromecast or Firestick to monitor your security camera footage on a larger screen
  • Watch your Lorex system in new ways. Don't have an option of hooking up your Lorex recorder directly to your TV, no problem, simply make sure your Lorex recorder is on the same network as your Apple TV (Gen 4 or newer) and watch your Lorex recorder on your TV through the Lorex Home Apple TV App
  • 4K security camera system will be up and running in no time thanks to Power-over-Ethernet (PoE) technology, all that is required to connect each of your security cameras to your NVR is a single Cat5e ethernet cable run, this cable provides both power and video transmission up to 300 ft. / 91 m
  • NVR brings your security camera system to the next level with an easy-to-use panic button located on the front of the recorder, by pressing and holding this button you can activate all lights and sirens on your compatible Smart Deterrence cameras at 1 time to deter potential intruders

Can you watch footage from a smart phone?

Asked by Dee November 29, 2020

Yes, you would need to connect the NVR to your router and have an Internet connection first. Once you do that you would need to download the Lorex Home App and you would be able to view it from your smart phone.

Big Mistake
If you don't mind a noisy fan running constantly this unit is for you. Customer support is a absolute joke and non existent with clueless tech people. Stay far away form Lorex.

I read reviews online about this w having loud fans....
I read reviews online about this w having loud fans. Its actually not that loud. We have put the DVR in a closet and can’t hear anything at all. Even if it was outside, the fans aren’t loud enough to cause disturbance. Video quality is spot on. Crisp and clear day and night. It also has a pretty decent night vision. Night vision looks better with black and white video. During daytime the video looks fine with color as well as black and white. Highly recommended system for home security.

The motion detection picks up absolutely everything within the cameras field of vision. Spent 2 hours on the phone with customer support and even they don't understand why it's happening. The zones are clearly marked but the system isn't using them. Also, there's no way to turn off the LED feature, so since the cameras seem to even pick up air movement, the lights are continuously going on and off every 30 seconds. I hate these cameras and I will be returning them.
solid system
Good beginner camera set, if you plan on adding more cameras you should probably consider a set that comes with more

The NVR is loud
Buyer be aware: There's a small cheap fan inside the NVR. I can here it running about 20 feet away. Lorex says that's normal. I say that's ridiculous.
