The anti-dew heater strip is used for anti-dew on the front window of the cooled cameras. This kit includes the zip-tie, anti-dew heater strip and an Y power cord:The thickness of the anti-dew heater strip is 0.2~0.3mm. The "Y" power cord is designed to connect in-line with the cooler power supply for convenience. We recommend a DC adapter giving 12V at 0.35 A resulting in a heating power on the strip that is around 4.2 watts. You can use one and same power cord to power both the 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 the cameras themselves. ASI071MC-P/ASI6200/ASI2600/ASI2400 cameras come with an anti-dew heater that heat the protective glass to avoid any dew problems. For ASI183/ASI1600/ASI294/ASI533 cameras, the heat emitting from the TEC be conducted to the camera case and avoid any dew problems when TEC cooling system is working. How to use it? 1. Tear out the protective film on adhesive tape 2. Put the anti-dew heater strip on the front facing of the camera and make sure the black cable is in the right position (lining next to the DC plug at the rear end) 3.
