Gold Medal of Securex for Redbeam IR illuminators
Redbeam IR20 is a modern IR illuminator for outdoor applications. The employed IR LED array generates a powerful (range up to 20 m) wide-angle (100o ) IR beam at 850 nm wavelength.
Distinguishing features:
- IR LED array
- Output power: 2400 mW,
- Maximum operational distance: 20 m
- Beam width: 100o (half-power beam width: 50o)
- 8-times longer life than of conventional IR LEDs
- Outdoor aluminum housing
IR illuminators of Redbeam series are modern devices for providing homogeneous IR light in the monitored area in order to enable CCTV cameras to capture images in low-light or no-light environments. The advantage of the series is application of a specially designed LED array (instead of a conventional set of diodes) which, together with optical lens/es, ensures desired operational angle and distance.
The IR illuminators of the series, cooperating with day/night cameras, make perfect sets for night surveillance. Their twilight sensors in combination with high-efficiency IR LEDs provide very good results, with relatively low power consumption.
A typical IR LED provides output power between 5 mW and 15 mW, so, even in the case of short operational distance, an IR illuminator has to employ many such diodes. The Redbeam IR20 illuminator provides 2400 mW! This means a much longer range, in spite of the small size of the device.
Comparison of IR illuminators with similar output power
The array of small size makes it easy to shape the beam with lenses. In the case of a traditional IR LED illuminator, the angle of the beam depends on the arrangement of LEDs, which is not a flexible solution. Using this LED array, virtually any angle can be achieved. The examples are the dome models M1642 and M1643, with beams of 180o.
Another advantage of the arrays is the lifetime of the materials used. Standard heavy-duty IR diodes operate around 6000 hours. In the case of the arrays, the expected lifetime is about 50000 hours. It means that they can work for over 10 years (12/24 cycle)!
The water-tight casing is made of aluminum. To prevent overheating, the body is formed as a radiator. The light beam is shaped by a lens system.
The illuminator should be mounted on a camera bracket (using one of the two 1/4" holes), or directly screwed to an outdoor housing, using M9950 screw (the distance between holes is 22 mm).
