With the latest in Color Night Vision technology and encased in an aluminum exterior built to withstand the harshest weather conditions, this camera is designed to provide 24/7 surveillance year-round.Varifocal cameras can zoom in and out using their 4x optical zoom lenses. Optical zooms mean that no video quality is lost when you are zoomed in, making these cameras extremely versatile.Smart Motion DetectionThis system comes with Smart 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.Ultra HD ResolutionNocturnal security cameras use an 8MP image sensor that delivers exceptionally detailed 4K Ultra HD resolution video and incomparable low-light performance.Long-Range IR Night VisionThis camera will use its 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 noticeable difference in quality, which will save you lots of hard drive space.Full Metal ExteriorsHeavy-duty aluminum exteriors not only provide additional protection against vandalism, but they will also extend the life cycle so you can count on years of uninterrupted service.Easy PoE InstallationIP cameras only need a single Cat5e ethernet cable to connect it to a compatible NVR. This cable provides video transmission, power to the camera, and a stable network connection.Extreme Weather CapabilitiesRated IP67, Nocturnal security cameras can endure anything from torrential downpours to freezing snowstorms.

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 which only you can access it, so there are no surprise fees or monthly cloud subscriptions.Regional Motion ZonesUsing 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 MaskingIf the camera is facing areas that you do not want to be recorded, activate the privacy masking. Use the NVR to draw a square around the spot(s) you don't want the camera to record.Multiple RecordingRecord 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.
