Metal nocturnal security camera housing

Durable metal camera housing

This housing of this security camera is built using high grade aluminum. This ensures that it is strong enough to withstand violent impacts, unlike conventional plastic security cameras.

Installation and Customization

easy to install IP security camera

Easy PoE installation

This security camera only needs a single Cat5e ethernet cable to connect it 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).

Regional motion zones security camera

Regional motion zones

Use your NVR to program this camera with up to four different motion zones. These zones can be customized to adjust the sensitivity (the amount of movement required to register that movement) and threshold (how much movement is required before creating a motion "event") of the camera. This means that more important areas, such as a doorway, can be set to make any movement at all trigger recording (or create a motion event), while other sections of the frame, like a tree, would need a much higher level of motion.

Privacy masking security camera

Privacy masking

In some cases, there are sections of the camera's field of view that you simply do not want it to record. Inside windows or perhaps your pool / hot tub, are good examples of this. Thankfully, you can use your NVR to literally mask out these sections by drawing a square or rectangle over the areas you don't want to record.

nocturnal security camera custom video orientation

Custom video orientation

Don't worry about installing this camera the "right side up." In fact, there is no right side up. You can easily change the visual orientation with the NVR after installation. The video feed can be rotated 90°, 180°, and 270°. It can also be flipped upside down and mirrored.
