Yes. There is any difference of heater performance depending on power source.
Outdoor PTZ camera has two built-in heaters.
When PoE+ is used, one built-in heater will be started.
When 24VAC or the Tested PoE injector (60 W) is used, two built-in heaters will be started.
Two heaters are suitable for low temperature.
Therefore in the low-temperature environments such as -30 degrees Celsius (-22 degrees Fahrenheit) and less,
or in the region with strong wind and heavy snow,
please use 24VAC or the Tested PoE injector (60 W).
