Outdoor smart security camera is constantly exposed to scorching sunlight. Temperature changes of the external environment can easily lead to a large amount of heat being accumulated inside the casing, resulting in pressure differences, lens rupture, seal failure and equipment damage. If the device is completely sealed, then internal water vapor cannot disperse, which will form condensations and affect lens performance. Therefore, the cavity is usually not completely sealed but leaving channels connecting to the external environment for pressure equalization. However, this leaves the device vulnerable to dust and rain intrusions, which may result in electronic components damage and short circuits, posing safety threats. IPRO screw-in vent can provide effective waterproof and dust-proof solutions, quickly equalize pressure, and reduce lens fogging caused by vapor condensation. What is more, it also prevents sealing structures failure, casing deformation and lens rupture, thus ensuring the long-term reliability of smart security cameras.
