Pixim Inc., a leading provider of imaging technology for enterprise security cameras, launched its Nightwolf imaging solution specifically designed for IR-assisted CCTV and IP cameras. Nightwolf eliminates hot spots common to IR cameras with near-field reflective objects in the scene and correctly exposes highlights as well as darker background details simultaneously—an unprecedented capability in the large market for IR-assisted video security cameras.
A typical IR-assisted CCD camera attempts to solve the hot spot problem by either closing down a mechanical iris or dimming the infrared LED lights. While either of these compromises can help avoid hot spot saturation, the resulting side effect is that the camera loses critical shadow detail greatly reducing the utility of the captured video. With innovative digital imaging technology, Pixim Nightwolf is able to capture both foreground and background details even in cases where very strong IR lighting is deployed. In fact, Nightwolf capability is so effective, that use of expensive mechanical DC iris lenses or adjustable infrared LEDs is no longer necessary.
