4K smart IP security camera
 

4K sharpness gets you the details you need

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.

Person and vehicle smart motion detection

Person and vehicle smart motion detection

Your cameras come 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 and image screenshot to your Lorex app whenever a person or vehicle is detected on your property. This effectively reduces the number of unwanted false alerts caused by moving branches or animals. All recorded motion alerts can easily be reviewed by using the Smart Search function in the Lorex mobile app.

security system with motion detection
deterrence security camera

Stop trespassers in their tracks with Smart Deterrence

Bright LEDs, a remotely triggered siren, and two-way audio make this security camera an extremely valuable asset to your IP security system. For example, the LED lights can be customized to always be on or triggered by motion. You can also choose a strobe light setting, in addition to setting a schedule for when the deterrence LEDs should automate. The remote-triggered siren is also designed to stop trespassers right in their tracks. When motion is detected within the sensor range, the system sends an alert to your Lorex app, allowing you to remotely access the camera and set off a siren to deter crime.

two way audio 4K security camera

Listen-in Audio and Two-Way Talk

A 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. This camera also has a speaker that allows you to communicate with others through the camera through the Lorex app. *


*Audio recording is disabled by default. Audio recording without consent is illegal in certain jurisdictions. Lorex Technology does not assume liability for any use of its products that fails to conform with local laws.

Lorex app

Remote viewing from your mobile with Lorex™

This feature-rich system is designed for use with our innovative, hassle-free Lorex™ app. Using Lorex, you can quickly and easily view your security system remotely from your smartphone or tablet and control smart deterrence features. Simply download the free app, scan the QR code on the NVR and your cameras will appear for you to monitor (or review footage). You can also program the app to send you motion-activated push notifications with screenshot attachments straight to your phone to keep you connected to your property at all times.

color night vision (CNV) bullet 4K IP security camera

Full-color video, even at night

There is usually an automatic shift from full color video to black and white when lighting conditions change at night. This is not the case for this security camera. It features our revolutionary Color Night Vision™ (CNV) technology, which will produce full-color video in low-light conditions*, provide a further level of detail (the color of clothes or cars, for example), and add increased contrast for easier detection and recognition of people and objects


*Please note that ambient lighting is needed for full-color night vision. The image will typically switch to black and white infrared in total darkness to ensure maximum quality night vision.

easy PoE IP camera installation

PoE plug-and-play installation

This 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 feet / 91m.

HEVC 4K IP security camera

H.265 / HEVC encoding

Your security camera and NVR are both equipped with High-Efficiency Video Encoding (HEVC) or H.265 video compression. This encoding technology efficiently compresses file sizes. In fact, it can compress file sizes up to 50% more than files using the previous encoding technology (H.264), without any noticeable degradation in quality. HEVC encoding will also save you plenty of bandwidth while watching live or recorded video remotely.

weatherproof 4K smart IP camera

Built for the outdoors

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 -4°F to 122°F (-20°C to 50°C). It also has a durable, all-metal sheath for added protection.

2TB security hard drive

Reliable security-grade hard drive preinstalled

A 2TB security grade hard drive (expandable up to 6TB) comes preinstalled within this NVR. 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.
