4K Ultra HD resolution

Capture high clarity footage with this top-of-the-line 4K IP security camera. This camera is equipped with an 8MP image senor at its core and will record 4K resolution video. With this high quality resolution, every detail will be captured with clear precision, assuring you that nothing will be left to question.

4K resolution chart

The 4K difference

This new 4K resolution camera records 4× the amount of pixels as compared to a 1080p security camera. This means that while a 1080p camera records at a pixel ratio of 1920 × 1080 (2,073,600 pixels), this 4K security camera records at a pixel ratio of 3840 × 2160 (8,294,400 pixels). This translates into much better quality video, especially when you need to digitally zoom in on particular details such as facial features. This is because there are simply more pixels available, so details will remain legible for longer as the digital zoom is applied.

4K audio security cameras

Listen-in audio

This security camera has a built-in microphone that can help provide additional information in case an event or intrusion occurs on your property.* This valuable feature is instrumental in providing extra evidence, such as voices. Having audio will also expand your security coverage beyond the camera's field of view, so even when something happens off-camera, you may still gain some additional information.

*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.

Long range color night vision

Rest assured that this security camera will protect your property even after the sun goes down. See up to 130ft / 40m away or up to 90ft / 27m away in total darkness with this camera's IR night vision range. With the help of exterior lights, you will also receive extra details that can help identify intruders or disturbances with Color Night Vision™ (CNV).*

*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.

PoE security camera installation

Easy PoE installation

Only a single CAT5e (or higher) ethernet cable is required to connect this security camera to a compatible NVR. No need to worry about multiple cables, as the camera doesn't need to be plugged into a power outlet (the NVR itself powers the camera through the ethernet cable). This cable also provides video transmission and a stable network connection up to 300ft from the NVR.

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

HEVC / H.265 compression

HEVC encoding helps compress 4K video files without losing the 4K video quality. HEVC, aka High Efficiency Video Compression, H.265 or MPEG-H Part 2, is an innovative compression technology that will compress video file sizes to free up space by using less data. In order to utilize this feature, the NVR must be compatible with this technology.
