You know the problem: as soon as it gets dark the images of your surveillance camera are useless. That your camera can provide you with clear images you require a light source. Solution: An infrared illuminator supplies your camera with light, inconspicuously and in absolute darkness. Thus IR-Illuminators are especially suitable for security relevant applications, where the presence of surveillance cameras should not be noticeable. No standard camera provides you with a good picture without suffucient light source. The application of bright and large-area spotlights is not always preferable as some applications require inconspicuous, discrete surveillance – even at night. VTQ’s IR-Illuminator are the ideal solution for this problem. As an IR-Illuminator is a light source that emits light in spectrum that is invisible for the human eye. The light is generated by a modern diode that is characterised by very high light power and low power consumption, despite the small size. Another advantage of this technique is the extreme long durableness of the diode. Our IR-Illuminator with up to 10 high-performance diode ensures the optimal illumination of the area monitored in the darkness and due to different wavelengths (850 or 940nm) they are suitable for almost all day/night – and black/white cameras. The coverage varies depending on the angle of radiation but also on the light sensitivity of the camera. Illumination between 15 and 70m are achieved by standard with a radiation angle between 17° to 120°. All VTQ IR Illuminator feature a controllable twilight switch. It switches the Illuminator on if the light strength is below an adjustable value. The adjustment is made by rotary switch. That saves energy and extends the durableness of the LEDs. The Illuminator may even switch to permanent operation. An optional synchronisation output for day/night-cameras ensures that the camera simoultaneously switches to night mode when switching on the Illuminator. The Illuminators are power supplied by a 12V voltage. Due to the optional integrated mains adapter the device may also be directly power supplied with 230V. All IR Illuminator are splash water protected and dustproof. The Illuminators of our “Professional Line” include mountig sets, so that they can be installed at walls or masts without problems. You may install it without hesitation in temperatures between –25°C to +50°C |
