Six 1080p HD security cameras comprise this exclusive security system from Lorex. Don’t miss a thing with smooth real-time 30 frames-per-second (FPS) on-screen movement.

PTZ security camera

Versatile PTZ lens

Your PTZ security camera has the ability to move its lens in virtually any direction, as well as being able to zoom in on objects in the distance. This PTZ camera features full 360° panning rotation, a -15° ~ 90° tilt ability, and an incredible 25× optical zoom lens.


Create PTZ Tours

Preset Tours Mobile

Expand your security coverage with fully automated PTZ tours. These tours are designed to cycle through a number of user-defined location presets. All of the pan, tilt, and zoom features can be used during a tour. You can also create a simple "pattern" movement that will automatically cycle the camera's viewpoint between two presets. These automated tour and pattern settings can be found in the NVR's PTZ settings menu.

Do not fear the dark with 1080p HD night vision security cameras from Lorex

See through the dark with outstanding night vision

The dome cameras included here contain cutting edge infrared (IR) LEDs that make it possible to see clearly through the dark up to 130ft / 40m in ambient lighting and up to 90ft / 28m away in total darkness. ClearNight imaging technology assists with low light operation and recording efficiency. SmartIR functionality helps with close up recognition, so you can be confident that your security cameras are watching even when you cannot.

See in color - even at night

The PTZ camera includes high powered infrared LEDs that can see up to 300ft at night with the help of ambient lighting. If there is plenty of ambient light, these cameras will automatically utilize our revolutionary Color Night Vision™ (CNV) technology. This important feature will add an additional level of visual information that can help identify people or objects and increase contrast for easier detection and recognition.

1080p metal PTZ IP camera from Lorex

Built for freezing climates

Both types of cameras included in this system can withstand extreme temperatures and feature an IP66 weatherproof rating. The PTZ security camera, in fact, can withstand freezing temperatures as low as -40°F / -40°C.

Easy Analog HD security camera installation

Single cable camera connection

Each analog security camera comes with a siamese BNC cable that provides video transmission and power to the camera. This cable can be run through walls to give you the flexibility to install the camera where you need it most. A wired video / power connectivity means constant connection to your cameras, so your recording never misses a beat.


Advanced motion detection

Be aware whenever motion is detected on your property with advanced motion detection. This system features person/vehicle detection on up to 4 channels which helps reduce unnecessary alerts and false alarms from moving branches or animals. Important motion events that are recorded can easily be found using the Smart Search feature, which organizes events by type (e.g. person/vehicle motion vs. general motion, etc.).
