System Overview

The IR Megapixel Vari-focal Eyeball camera delivers 4MP resolution with a motorised 2.7mm – 12mm varifocal lens. The camera’s elegant blend of aesthetics combined with a range of easy mounting solutions provides an excellent choice for a variety of small to mid-size applications at an affordable price.

True Day/Night

A day/night mechanical IR cut filter makes this camera ideal for applications with fluctuating lighting conditions, delivering colour images during the day and automatically switching to monochrome as the scene darkens

Regions of Interest (ROI)

Regions of Interest (ROI) is a user defined feature that allows the operator to monitor specific areas of a scene while still maintaining overall situational awareness of less important areas

Smart IR

With IR illumination, detailed images can be captured in low light or total darkness. The camera’s Smart IR technology adjusts to the intensity of camera’s infrared LEDs to compensate for the distance of an object. Smart IR technology prevents IR LEDS from whiting out images as they come closer to the camera. The camera’s integrated infrared illumination provides high performance in extreme low-light environments up to 30m (98ft).

Environmental & Protection

Supporting ±10% input voltage tolerance, this camera suits even the most unstable conditions for outdoor applications. Its 6KV lightning rating provides protection against the camera and its structure from the effects of lightning

Image Flip

Capturing unnecessary data such as surrounding hallway walls can increase storage requirements without any added value. The image flip feature allows the camera’s image to be rotated in 90° increments for better video optimisation.

Wide Dynamic Range (WDR)

Embedded with industry leading wide dynamic range (WDR) technology, vivid pictures are achieved even in the most intense contrast lighting conditions. For applications with both bright and low lighting conditions that change quickly, True WDR (120dB) optimises both the bright and dark areas of a scene at the same time to provide usable video.
