What's the difference between VESA and proprietary camera mounts?
VESA (75/100/200 mm) are universal screw-hole patterns used by monitors and some IP cameras, allowing mixed-brand bracket compatibility. Proprietary mounts are manufacturer-specific and often integrate cable routing and power connectors for a given camera family. Always verify your camera's mounting interface before ordering; mixing standards can misalign the lens or create cable stress.
How do I choose between wall, pole, and ceiling mounting?
Wall mounts suit indoor hallways and perimeter coverage; ceiling mounts provide overhead overview angles; pole mounts enable tall outdoor installations for parking lots and large perimeters. Consider viewing angle (DORI distance), cable routing (PoE run length), and environmental exposure (rain, wind, UV). Outdoor deployments typically require pole or soffit brackets with stainless hardware and weatherproof conduit seals.
What wind-load rating do I need for rooftop or pole-mounted cameras?
Most outdoor brackets are rated 60–80 mph; rooftop and tall-pole installations in high-wind zones (hurricane, mountain, or exposed coastal areas) require 100–150+ mph ratings. Consult local building codes and weather records for your site. Undersized brackets allow camera drift, misaligning views and degrading identification accuracy over distance.
Why should I use stainless steel brackets in coastal or humid climates?
Standard steel and galvanized coatings corrode within 2–5 years in salt-spray or high-humidity zones, causing bracket failure and camera drop hazards. Stainless 304 resists general corrosion; 316-grade adds molybdenum for superior marine tolerance. The upfront cost (typically 20–40% more) prevents emergency replacement and liability exposure.
What's an IP67 cable gland, and why does it matter for outdoor mounts?
IP67 means the gland prevents dust and temporary water submersion at cable entry points. Water ingress corrodes connectors and shorts PoE circuits, causing mid-deployment failures. Pair IP67 glands with silicone gaskets and stainless fasteners; test seals before final installation to confirm weatherproofing.
Can I use the same mounting bracket for different camera brands?
Only if both cameras share VESA or ISO mounting standards. Proprietary mounts (common in Axis, Vivotek, and Hanwha models) are not interchangeable. Mixing brands often requires adapter plates, which add bulk, cost, and potential optical misalignment. Standardize on one or two manufacturer families per project to simplify spare-parts inventory and on-site troubleshooting.
