Johnson Controls has added four new models to its Tyco Illustra Essentials IP camera range. The new fourth-generation Essentials mini-dome, varifocal mini-dome, bullet, and varifocal bullet cameras, which supersede their respective older models, are all equipped with built-in adaptive IR illumination which enables them to capture up to two-megapixel HD resolution images of objects in total darkness up to a distance of 30m (98ft).
