Vancouver Island doesn't destroy security cameras with anything dramatic. It does it slowly, with eight months of rain, fog and condensation working on every shortcut the installer took. The failures we're called to fix follow the same short list every winter: domes that fog from the inside, connectors green with corrosion, water that walked down a cable into a junction box, and infrared night vision blinded by its own reflection in the mist. Every one of those failures is preventable — not with exotic equipment, but with installation practices designed for a marine climate. Here is each failure, and the practice that stops it.

The cause is rarely rain getting in from outside — it's moist air that was sealed in, or drawn in, and condensing on the inside of the dome when the temperature drops. Coastal air carries moisture year-round, and a housing opened on a damp day traps that day inside it forever.
Prevention is about discipline at install time: housings closed up with their desiccant packs in place and gaskets seated properly, cable glands actually tightened rather than finger-snugged, and no drilled holes in the housing body for a convenient cable path. A camera rated for wet environments only performs to its rating if every seal the factory designed is intact when the installer walks away.
Network and power connectors are the most vulnerable centimetres of an entire camera system. Left exposed — dangling behind a camera, coiled in an eave, resting in an unsealed box — the contacts corrode in marine air, and the symptoms arrive months later as intermittent dropouts, cameras that reboot in heavy weather, and image glitches nobody can reproduce on a sunny day. Intermittent faults are the most expensive kind, because they're the hardest to find.
The fix is to treat every connection as if it will spend a decade in fog, because it will. Connections live inside sealed, rated junction boxes or inside the building envelope — never in open air. Where a connection must sit outside, it gets a gel-filled or gasketed weatherproof coupler, mounted so water drains away from it rather than pooling on it. Done once, done properly, it simply never becomes a service call.
Water is patient and cable is a highway. Rain landing anywhere on an exterior run will follow the cable — along its jacket, down its slope, through any penetration — until it finds something expensive: a connector, a junction box, or the hole in your wall. Some of the worst damage we see isn't at the camera at all; it's inside the wall where an unsealed penetration let a wet cable drip into the framing for two winters.
Two old-school practices prevent nearly all of it. First, the drip loop: the cable dips below its entry point before rising into it, so water falls off the bottom of the loop instead of following the cable inside. Second, sealed penetrations: every hole through cladding or soffit gets a proper gland or sealant around the cable, checked as part of any later service. Neither costs anything to speak of. Both are routinely skipped by installers in a hurry.
Infrared night vision works by flooding the scene with light your eye can't see. In fog, mist or heavy rain, that flood reflects straight back off the water droplets into the lens — a whiteout that turns the recording into a glowing wall exactly when visibility matters most. Rain streaks on a dome, and even a single strand of spider silk in front of the IR array, produce the same blinding glare.
The design answers: mount cameras under shelter — eaves and soffits — so lenses stay dry and the IR array isn't firing through a wet dome; prefer turret-style cameras over domes in exposed positions, since they separate the IR emitters from the lens window; and on important sightlines, use separate external IR or white-light illuminators placed away from the camera, so the reflection bounces away from the lens rather than into it. Good placement beats raw IR power every time on this coast.
Weather ratings on the box are entry criteria, not the whole answer. Equipment for exposed Island positions should be rated for sustained wet and built with metal housings and proper gaskets — but an honest install spec matters more: the same camera lasts years longer under a soffit than bolted to an exposed fascia taking horizontal November rain.
That's why our exterior layouts start with the building's sheltered geometry — eaves, soffits, covered entries — and work outward, reserving fully exposed mounts for positions that genuinely can't be covered any other way, and specifying them accordingly. A wet-coast camera system isn't a parts list. It's a set of decisions about where water will go, made before the first hole is drilled.
