Advanced Motion Detection This system comes with advanced person and vehicle detection that helps identify more important objects that enter the camera's field of view. Thanks to this innovative feature, you will only get a push notification to your Lorex Cloud app whenever motion from a person/vehicle is detected on your property. This effectively reduces the number of unwanted false alerts caused by moving branches or animals.

Ultra HD Resolution Nocturnal security cameras use an 8MP image sensor that delivers exceptionally detailed 4K Ultra HD resolution video. Long-range IR night vision This camera will use it's infrared LEDs in regular nighttime conditions that are too dark for CNV to render full-color images. High Dynamic Range (HDR) HDR improves video clarity in high-contrast lighting, revealing details in extremely bright and dark areas of the image. High Efficiency Video Coding (HEVC) HEVC compresses video file sizes without any noticable difference in quality, which will save you lots of hard drive space. Full Metal Exteriors Heavy-duty aluminum exteriors will extend the life-cycle so you can count on years of uninterupted service. Easy PoE Installation IP cameras only need a single Cat5e ethernet cable to connect it to a compatible NVR for video, power and a stable network connection.

Designed to meet the high workload demands of continuous security monitoring, this heavy-duty hard drive can reliably record weeks (even months) of footage without taking a break. All recorded footage is then safely stored on the hard drive where only you can access it, so there are no surprise fees or monthly cloud subscriptions. Regional Motion Zones Using the NVR, you can program specific motion zones so that they are customized for heightened sensitivity (the amount of motion needed to register that movement) and threshold (how much motion is needed before creating a motion "event"). Privacy Masking In the event that the camera is facing areas that you do not want recorded, simply activate the privacy masking option. Use the NVR to draw a square around the spot(s) you don't want the camera to record. Multiple Recording Options Record security footage continuously, during scheduled times, or when movement is detected. Motion recordings include a pre-recording function that will go back to record the five seconds before activity is detected. Â
