IP camera with heat-conducting element for preventing dew condensation
An IP Camera includes a heat-generating element, a lens holder, a lens assembly and a heat-conducting element. The lens assembly includes a lens, a front portion and a rear portion opposite to the front portion. The front portion surrounds the lens. The lens assembly is disposed on the lens holder with the rear portion. The heat-conducting element has a thermal conductivity greater than 5 W/mK. The heat-conducting element is in contact with the heat-generating element, and a portion of the heat-conducting element surrounds the front portion.
1. An IP Camera comprising:
a heat-generating element;
a lens holder;
a lens assembly comprising a lens, a front portion and a rear portion opposite to the front portion, the front portion surrounding the lens, the lens assembly disposed on the lens holder with the rear portion; and
a heat-conducting element with a thermal conductivity greater than 5 W/mK, the heat-conducting element being in contact with the heat-generating element, a portion of the heat-conducting element extending towards the front portion and laterally surrounding the front portion, wherein the portion of the heat-conducting element is spaced from the front portion with an annular gap having a width less than 5 millimeters.
2. The IP Camera according to claim 1 , wherein the heat-conducting element comprises at least one heat-dissipating fin arranged around the lens assembly.
3. The IP Camera according to claim 1 , wherein a rated power of the heat-generating element is greater than 0.5 Watt.
