Are CCTV Cameras Waterproof? Understanding Weather Resistance

Closed-circuit television (CCTV) cameras are commonly used for video surveillance both indoors and outdoors. But can these security cameras withstand exposure to water or moisture? While most indoor CCTV cameras are not waterproof, many outdoor models are designed to be fully weather-resistant.

In short, the answer is yes and no. Some CCTV cameras are waterproof, while others are only water resistant. CCTV cameras have varying degrees of waterproofing and protection based on the intended usage environment and housing construction.

By selecting proper camera housings rated for wet conditions and utilizing weatherproof installation techniques, both analog and IP CCTV systems can be deployed in rainy, humid, or very wet locations.

Are CCTVs fully Waterproof or They are Water Resistant?

The difference between waterproof and water-resistant is important to understand when choosing a CCTV camera. A waterproof camera can be submerged in water without being damaged, while a water-resistant camera can only withstand splashes of water.

Most CCTV cameras are water resistant, not waterproof. This means that they can withstand rain, snow, and other mild weather conditions, but they should not be submerged in water. This is because water-resistant cameras have seals that keep water out, but these seals can be compromised if the camera is submerged for too long or if it is exposed to high-pressure water.

Fully waterproof CCTV cameras, on the other hand, are designed to withstand immersion in water. These cameras have special seals and gaskets that keep water out, even at high pressure. Fully waterproof CCTV cameras are typically used in harsh environments, such as swimming pools, marinas, and construction sites.

Water Resistance Level for Different CCTVs

The water resistance level of a CCTV camera is typically indicated by its IP rating. The IP rating is a two-digit number that indicates the level of protection that the camera has against dust and water ingress.

The first digit of the IP rating indicates the level of dust protection, while the second digit indicates the level of water protection.

Indoor CCTV Cameras

Most CCTV cameras designed for indoor use only are not waterproof or weatherproof:

Standard indoor CCTV cameras have an IP rating of IP00, meaning no protection against water or dust ingress.
They are typically rated for dry environments only with maximum humidity of 90-95%.
Indoor camera housings are made of plastic or light metal, allowing moisture intrusion.
CCTV cameras meant for interior spaces can be damaged by direct water contact or very high humidity.
Features like exposed ports, uncovered vents, and open bases make typical indoor CCTVs vulnerable.

Unless specifically rated as water-resistant, indoor CCTV cameras should be kept dry and never exposed to rain or sprinklers.

Outdoor CCTV Cameras

In contrast, CCTV cameras marketed as outdoor or weatherproof models are designed to withstand wet environments:

Outdoor CCTVs usually have an IP66 or IP67 rating, meaning totally protected against dust and protected against immersion in 1+ meters of water.
Housings are made of waterproof materials like hardened plastic or aluminum.
Rubber gaskets and seals prevent moisture from entering camera bodies.
Most exterior CCTVs can operate in heavy rain, snow, high humidity, and wet locations.
Features like covered ports, sealed vents, and no openings keep internal components dry.

Check manufacturer IP ratings, but most outdoor CCTV cameras can handle full water and weather exposure.

IP CCTV Camera Resistance

For IP network cameras:

Look for IP66 or IP67 ratings to indicate water and dustproofing.
Metal vandal-resistant domes offer protection for outdoor IP cameras.
Avoid models marketed only for indoor use.
Ensure all network cable openings are properly sealed.
Power over Ethernet (PoE) IP cameras have higher waterproof ratings than older wired CCTVs.

IP CCTVs meeting outdoor IP ratings provide reliable operation in wet and rainy conditions.

Analog CCTV Camera Resistance

For analog CCTV cameras:

Analog cameras rely more on watertight housing designs rather than high IP ratings.
But many durable, weatherproof housings are available.
Dome bubbles and camera “cans” protect external analog cameras.
Ensure coax connections have weatherproof BNC connectors and sealing.
Avoid models with more exposed wiring.

While rated lower than IP cameras, rugged analog CCTVs in protective housings can also withstand water and moisture.

Improving Water Protection

To augment protection:

Use outdoor-rated housings for indoor cameras installed under eaves or porches.
Seal any openings with silicone caulk.
Add a clear conformal coating to circuit boards.
Install waterproof conduit for wiring.
Provide an overhang above the cameras.
Check the condition of housings and cables periodically.

Extra measures like protective enclosures and routine maintenance can waterproof indoor CCTV cameras for uncovered outdoor use.

End Thoughts

Whether or not a CCTV camera is waterproof depends on the make and model of the camera. Most CCTV cameras are water resistant, but there are some that are fully waterproof. When choosing a CCTV camera, it is important to select one with an IP rating that is appropriate for the environment in which it will be used.
