In surveillance industry, with the growing popularity of the all-weather monitoring, the requirement of IR LED is getting higher and higher. And the brightness, reliability as well as lifespan become vital indexes for camera’s quality. Perfect night view is important to professional surveillance systems, it built up from advanced technology, not just a thing of LED chips.
Initially, DIP IR LEDs with diameter of 3 mm, 5 mm, 8 mm were wildly used by camera manufacturers. However, Hikvision, as forerunner of the infrared camera, took the lead in developing EXIR camera a few years ago. With the boost of market demand and continuous technical progress, based on EXIR 1.0, Hikvision officially launched the new generation infrared technology, EXIR 2.0.

No IR Reflection or Bleeding. Having the IR LEDs housed independently from the camera lens completely eliminates the chance of internal IR reflection and IR bleeding which can be a problem with dome cameras in particular. A curved, reflective glass dome cover can inevitably reflect the IR back and blind the camera which we've covered before, and an EXIR camera doesn't suffer from this, allowing Hikvision to install stronger EXIR LEDs with no risk.
Better IR Coverage. Traditionally, IR has been integrated in a circular array of many LEDs around the lens. This brought with it the common problem of a circular overexposed area in the centre of the image, with the corners being underexposed due to an uneven IR coverage. The rectangular EXIR LEDs provide a much more even coverage across the entire image, eliminating this issue.
Long lifespan. Under the condition of the same heat dissipation, EXIR 2.0 enables longer lifespan because of its better heat dissipation performance. For EXIR1.0, its lifespan is about 20000-30000 hours, while for EXIR 2.0, it’s about 30000-40000 hours. Compare to DIP LED which is less than 20000 hours.
Long infrared distance Benefit from the improvement of software and hardware, EXIR 2.0 provides better infrared effect for near-to-mid-range cameras (infrared distance within 80m, focus with 25mm), better meeting the needs of the near-to-mid-range market.
Better weather resistance and temperature resistance. The main ingredient of DIP LED’s sealing glue is epoxy resin. While for EXIR 2.0, it is silica gel which enables better weather resistance and temperature resistance.
Higher brightness, less power consumption. Luminous power which refers to the optical radiation power under nominal power consumption is an important parameter to evaluate LED chips. Larger luminous power means higher brightness. The luminous power of EXIR 2.0 LED is about 350mW. And for DIP LED, it’s about 25mW. Thus, one EXIR 2.0 LED’s brightness is equal to that of 14-16 DIP IR LEDs. The brightness of EXIR 2.0 is higher, so compared with DIP LED, its infrared board is smaller under the same brightness. Consequently, it can be applied to camera with smaller size, bringing customer more choices.
