The bracket carries wind load, vibration and the weight of the unit — the most underrated part of any outdoor installation.

• Load headroom: choose a bracket rated for at least twice the combined weight of the camera and accessories, and more where wind load applies — especially on tall poles or roof mounts.
• Material and finish: outdoors, prefer stainless steel or treated aluminium. Plain steel corrodes quickly in humid or coastal environments and becomes a breakage risk.
• Fixing method: expansion bolts into concrete; hollow brick and plasterboard need proper anchors or a backing plate. Never rely on self-tapping screws alone.
• Water management: fit a sealing washer between bracket and wall, keep the cable entry pointing down, and use a waterproof gland so water cannot run down the bracket or cable into the housing.
• Adjustability: a bracket with three-axis fine adjustment makes accurate framing much easier. Use thread-locking compound or spring washers on the fixing screws.

Acceptance check: give the mounted camera a gentle push sideways. Any visible movement or rattle means it is not secure and the work must be redone.
