The ir illuminator comes standard with a 1/4" threaded mounting to attach it to your sionyx aurora camera. additionally, you will also receive a weaver/picatinny mount, two rechargeable batteries with a charger and a transport case. When do i need ir and when not? Despite the fact that the sionyx auroras are equipped with very light sensitive cmos sensors: a certain form of residual light (such as moon or starlight) remains necessary. in some situations there may be no residual light at all, for example in a dark house or in a remote forest in complete darkness. therefore, extra infrared light may sometimes be necessary. with this ir set you create that extra light, which is visible through the night vision cameras but not with the human eye. this way you are still able to see. However, there are also situations that ir is certainly not desired, such as airsoft or paintball. the infrared light is not visible to your own eye, but your opponents are able to see it through their night vision camera. obviously you can still use an ir illuminator for those purposes and turn it off when desired.
