4K MPX security camera

Ultra HD security camera

The main reason to purchase a security camera is to capture useful evidence should an incident ever occur on your property. Well, your 4K cameras will do just that. They are capable of recording a 4K pixel resolution of 3840 × 2160 - that's 4× the amount of pixels of 1080p resolution. A foremost benefit of this higher resolution is that it allows for greater digital zooms while reviewing video. This means that details in the distance of the video will remain visible for longer as the digital zoom is applied.

4K resolution is here

These powerful MPX security cameras are capable of 4K video. This ensures the highest level of detail in your recordings. The higher pixel count will not only provide you with a new level clarity, it will add an increased ability to digitally zoom in on distant objects. So if an incident occurs, 4K resolution will offer the best chance to capture distinct details for evidence.

See at night - in color!

With the help of some external lighting, your security cameras will automatically utilize our Color Night Vision™ (CNV) technology. CNV provides extra details for evidence, such as the color of clothes or the color of a car. Without any external lighting sources, the camera will automatically switch to infrared black and white night vision.

Long-range infrared night vision

Expect to see up to 150ft (46m) in ambient nighttime conditions and up to 100ft (31m) in total darkness thanks to the large 1/2" image sensor and two especially powerful 850nm infrared LEDs. These LEDs essentially flood the scene in front of the camera in infrared light, which, although invisible to the naked eye, can be detected by the camera's image sensor. Smart IR imaging also ensures that close-up objects or people will not be over-exposed by the infrared lights.

Expanded coverage with built in microphone

Not only will you receive 4K video footage with your security cameras, a built-in microphone will let you capture audio as well.* This feature can provide you with more information (such as voices) should an intrusion ever occur. It will also help you to interpret events (even if they occur off-screen).
