When it comes to outdoor camera installations, ensuring their resilience against the elements is paramount. Here’s why silicon sealing plays a crucial role in safeguarding these camera mounts:

  • Protection Against Weather: New Zealand’s weather patterns, particularly on west and south-facing walls, can pose significant threats to outdoor camera installations. Rain and wind are common elements that can damage camera mounts, potentially compromising their stability and effectiveness.

  • Silicon Sealing: To address these weather vulnerabilities, silicon sealing is employed to create a watertight barrier around the camera mounts. This protective seal serves as a safeguard against moisture intrusion, ensuring that the mounting holes in the structure remain secure and unaffected by adverse weather conditions.

  • Sustaining Structural Integrity: Silicon sealing not only preserves the functionality of the camera mounts but also contributes to the structural integrity of the installation. By effectively sealing the mount, it minimizes the risk of water damage, which could weaken the mounting points or the surrounding structure.

Mounting Challenges: Outdoor cameras are often placed in elevated positions, which can be challenging to access. Installers may need to drill mounts into roofs, underhangs, light poles, or directly onto walls. This requires careful consideration of where to drill to ensure optimal surveillance coverage while minimizing any potential risks associated with height.

Silicon sealing is a critical step in weatherproofing outdoor camera mounts. It provides a reliable barrier against the elements, preserving the structural integrity of the installation and ensuring the continued effectiveness of the surveillance system, even in the face of New Zealand’s variable weather conditions.
