In the case of IP66, here's what each digit signifies:
1. Solid Object Protection (First Digit):
The first digit in IP66 represents the level of protection against solid objects, such as dust, dirt, and other foreign particles. In the case of IP66, the digit "6" indicates a high level of protection against solid objects. The "6" rating signifies that the camera or enclosure is fully protected against dust and other particulate matter. It implies that the camera is dust-tight and will prevent the ingress of any solid objects that could potentially interfere with its functioning.
2. Liquid Protection (Second Digit):
The second digit in IP66 represents the level of protection against liquids, particularly water. In the case of IP66, the digit "6" indicates a high level of protection against water. The "6" rating signifies that the camera or enclosure is protected against powerful jets of water from any direction. It implies that the camera is water-resistant and can withstand heavy rain or water splashes without being affected.
Overall, an IP66 rating for a CCTV camera or kit indicates that it is highly resistant to dust and water. This rating makes it suitable for outdoor use and ensures reliable operation even in challenging environmental conditions.
It's important to note that while an IP66 rating provides a high level of protection against dust and water, it does not guarantee complete submersion in water. If you require a higher level of water resistance, you may need to consider cameras or enclosures with a higher IP rating, such as IP67 or IP68.
