The anti-dew heater strip is used for anti-dew on front window of cooled cameras. This kit includes zip-tie, anti-dew heater strip and an Y power cord:The thickness of anti-dew heater strip is 0.2~0.3mm. The "Y" power cord is designed to connect in-line with cooler power supply for convenience. We recommend a DC adapter giving 12V at 0.35 A resulting in a heating power on strip that is around 4.2 watts. You can use one and same power cord to power both fan and heater simultaneously, but make sure not to exceed recommended amount of Ampere. NOTE: for many cameras a heater strip is not necessary since they have one that is built into cameras themselves. ASI071MC-P/ASI6200/ASI2600/ASI2400 cameras come with an anti-dew heater that heat protective glass to avoid any dew problems. For ASI183/ASI1600/ASI294/ASI533 cameras, the heat emitting from TEC be conducted to camera case and avoid any dew problems when TEC cooling system is working. How to use it? 1.
