4mp dome security cameras

4K Ultra HD resolution

An 8MP image sensor is at the core of this security camera. This means that it is capable of recording a 4K pixel resolution of 3840 × 2160 at 15 frames-per-second (FPS). This resolution will deliver extremely detailed video and allow for greater digital zooms while reviewing recorded video.

4K dome audio security camera

Built-in microphone

This security camera allows for listen-in audio recording.* Audio monitoring can provide you with additional information (such as voices), which could prove to be invaluable should an intrusion or event occur on your property. Audio can also help you interpret events, even if the action takes place away from the camera's field of view.

*Please note, audio recording without consent is illegal in certain jurisdictions. Lorex Corporation assumes no liability for the use of its products that do not conform with local laws.

PoE security camera installation

Easy PoE installation

Only a single Cat5e ethernet cable is required to connect this security camera to a compatible NVR. This cable provides video transmission, power to the camera, a stable network connection, and installation flexibility up to 300ft* (as the camera does not need to be plugged into a nearby power source).

*Click here to purchase extension cables. You can also incorporate a PoE switch if more distance is needed.

HEVC / H.265 compression

This camera uses cutting-edge HEVC compression technology. High Efficiency Video Compression (also known as H.265 or MPEG-H Part 2), is used by the camera to compress video file sizes without any noticeable difference in quality. This allows you to keep the 4K resolution video without the 4K file size. Please note that an NVR capable of receiving this type of compression is necessary to utilize this feature.

Long range color night vision

Trust this security camera to protect your property around-the-clock. Not only will this security camera allow you to clearly see up to 130ft / 40m away with the help of ambient lighting (or up to 90ft / 27m away in total darkness), it will also take your night vision security coverage one step further with our Color Night Vision™ (CNV) technology. This feature will provide full-color video in low-light conditions that will add an extra level of visual detail that can help identify people or objects.*

*It is important to note that CNV requires ambient light - the camera will typically switch to black and white infrared night vision if the area is too dark.

2K weatherproof security camera for year-round protection

All-weather security camera

This security camera is rated IP66 (weatherproof), which means that it can withstand both torrential downpours and furious snowstorms. It will even continue to operate in freezing climates as low as -22°F / -30°C. This allows you to place it where you need it most - indoors or outdoors. Its heavy duty housing is also well equipped to withstand vandalism, providing additional protection for safe outdoor installation.
