The short answer
For outdoor CCTV in Bangalore, choose cameras rated at least IP66. That covers dust and heavy monsoon rain. IP67 adds protection against short immersion, which matters where water can pool or where cameras are hosed down.
How to read an IP rating
IP stands for Ingress Protection and is defined by the international standard IEC 60529. The first digit is protection against solids such as dust (0 to 6). The second digit is protection against water (0 to 9). So IP66 means dust-tight (6) and protected against powerful water jets (6).
| Rating | Dust | Water |
|---|---|---|
| IP65 | Dust-tight | Water jets from any direction |
| IP66 | Dust-tight | Powerful water jets, such as heavy driving rain |
| IP67 | Dust-tight | Temporary immersion, up to 1 metre for 30 minutes |
| IP68 | Dust-tight | Continuous immersion, to a depth the maker specifies |
IP67 is not simply 'better' than IP66
This surprises people. Jet tests and immersion tests are different tests. A product that passed the immersion test (IP67) has not necessarily passed the powerful-jet test (IP66). Good outdoor cameras are tested for both and say so as 'IP66/IP67' on the datasheet.
For a camera on a wall or pole, driving rain is the real risk, so IP66 is the number that matters most.
Which rating for which place
- Covered porch or parking under a slab: IP66 is plenty; even IP65 cameras manage, but IP66 costs little extra.
- Open walls, gates, boundary poles: IP66 minimum.
- Factory areas that are washed down, food processing, car wash bays: IP66/IP67, with stainless or well-sealed housings.
- Low positions where water can collect or splash heavily: IP67.
- Dusty sites — cement, stone crushing, construction: the dust digit must be 6; also plan regular lens cleaning.
The weak point is usually the cable, not the camera
Most water damage we see on outdoor cameras comes in through the cable joint, not the camera body. The camera's pigtail connector is exposed to the weather unless it is sealed properly.
Good installation means a proper junction box behind or under the camera, the waterproof cap supplied with the network connector fitted correctly, cable glands that grip the cable, and a drip loop so water runs off before it reaches the joint. Cable entering from below is far safer than cable entering from above.
Monsoon-proofing outdoor cameras and gate motors →Other outdoor factors
- Heat: check the operating temperature range, and avoid mounting where the camera sits in full afternoon sun against a dark wall if you can.
- Corrosion: near the sea or chemical plants, choose metal housings with good coatings and stainless fixings.
- Impact: if the camera is within reach, look at the IK rating as well — IK10 is the vandal-resistant grade.
- Sunshields: they reduce glare and heat and keep rain off the lens.
Planning outdoor cameras
During a site survey we look at where each outdoor camera will sit, how cable will reach it and how the joint will be protected. That is what keeps cameras working through the monsoon year after year.

A camera on an exposed terrace in Banashankari failed twice in one monsoon, even though it was rated IP67. Inspection found the problem was not the camera body: the cable joint behind it was wrapped in tape, with no junction box and no drip loop, so rainwater ran along the cable into the connector. The fix was a weatherproof junction box mounted behind the camera, a sealed connector, a drip loop and silicone at the wall entry. The same camera model has worked ever since. The IP rating protects the camera; installation protects the connection.
Monsoon-proofing outdoor cameras and gate motors →Quick answers
Is IP66 good enough for rain?+
Yes. IP66 is tested against powerful water jets, which is tougher than heavy rain. It is the standard choice for outdoor CCTV.
Can I use an indoor camera outside under a roof?+
It is risky. Wind-blown rain, humidity and dust still reach covered areas. Use an outdoor-rated IP66 camera.
Why did water get into my IP67 camera?+
Usually through the cable connector or a badly sealed junction box, not the camera body. Proper sealing and a drip loop prevent this.
Is IP66 enough for Bangalore weather?+
Yes, for wall and pole mounted cameras exposed to rain. IP67 adds protection against temporary immersion.
Why does water get into rated cameras?+
Usually through cable joints and connectors that are not sealed, rather than the camera housing itself.
