Is Your Unifi Camera Exposed to the Elements?
Unifi cameras are renowned for their performance within the Unifi Protect ecosystem, but not all models are designed to withstand the rigours of the great outdoors. Using a camera that isn't weatherproof in an exposed location can lead to significant damage from rain, humidity, dust, and extreme temperatures. This guide will help you understand the risks and take the necessary steps to protect your investment.
If your Unifi camera has been exposed to weather and is now malfunctioning, you may be facing a difficult situation. Water damage can often be irreversible, but let's explore the issue and see what can be done.
## Understanding Weatherproofing in Unifi Cameras
It's crucial to know the capabilities of your specific camera model. Unifi produces a range of cameras, and their suitability for outdoor use varies significantly.
- Indoor-Only Models: Cameras like the G3 Instant and G4 Dome are not rated for outdoor use. They lack the seals and durable casing required to protect against moisture and dust.
- Outdoor-Rated Models: Cameras such as the G4 Pro, G4 Bullet, and G5 Pro have IP (Ingress Protection) ratings that specify their resistance to solids and liquids. An IP67 rating, for example, means the device is dust-tight and can be immersed in water up to one metre deep.
Always check the official specifications for your camera model before installation. Assuming a camera is weatherproof without confirmation is a common and costly mistake.
## Common Symptoms of Weather Damage
If you suspect your non-weatherproof Unifi camera has been compromised by the environment, you'll likely notice one or more of the following symptoms:
- Condensation Inside the Lens: A foggy or hazy image is a classic sign that moisture has penetrated the camera's housing.
- Complete Failure to Power On: Water ingress can short-circuit the internal components, leading to a dead device.
- Intermittent Connectivity: The camera may frequently disconnect from the Unifi Protect controller due to corrosion on the Ethernet port.
- Image Artefacts: Distorted colours, lines on the screen, or a completely black image can indicate damage to the image sensor.
- Physical Deterioration: The plastic casing may become brittle and crack due to sun exposure or extreme cold.
## How to Protect a Non-Weatherproof Camera
If you must place a non-weatherproof camera in a location with some exposure, such as a covered porch or eaves, taking protective measures is essential.
- Strategic Placement: Install the camera in the most sheltered position possible. Place it high up under deep eaves or within a porch, away from direct rainfall and prevailing winds.
- Use a Protective Housing: Consider purchasing a third-party weatherproof enclosure. These cases are designed to seal the camera from the elements. Ensure the housing you choose is compatible with your camera model.
- Seal Cable Entries: When running the Ethernet cable, ensure the entry point into the wall or soffit is sealed with silicone to prevent water from travelling along the cable to the camera's port.
- Drip Loops: Create a 'drip loop' with the cable before it connects to the camera. This involves making a small U-shaped dip in the cable so that water drips off the bottom of the loop rather than running into the camera's connector.
## Attempting to Recover a Damaged Camera
If your camera has already been exposed to moisture, here are some steps you can try, although success is not guaranteed:
- Disconnect Power Immediately: The first and most important step is to unplug the Ethernet cable to cut the Power over Ethernet (PoE) supply. This can prevent further short-circuiting.
- Dry the Device: Bring the camera indoors. If you can safely open the housing (note: this may void your warranty), do so to allow air to circulate. Place the camera in a warm, dry place, such as an airing cupboard, for several days. You can also place it in a sealed container with silica gel packets to help absorb moisture. Do not use a hair dryer or other direct heat source, as this can damage the components.
- Inspect and Clean: Once thoroughly dry, inspect the Ethernet port and any other connectors for signs of corrosion (a green or white powdery substance). You can try cleaning this off carefully with a soft brush and isopropyl alcohol.
- Test with Caution: After waiting at least 48-72 hours, try reconnecting the camera to a PoE switch. Monitor its performance closely.
Unfortunately, if the internal electronics have been short-circuited, the camera is likely beyond repair. In this case, you will need to replace the unit with a model that is appropriately rated for the installation environment.
