      Protection is very important! Teach you awareness and testing of security products IP protection class
      Security products are now microelectronic products, especially security monitoring devices, these products have a high density, high speed, low voltage and low power consumption. Therefore, these products are very sensitive to IP protection class requirements are relatively high, if these parameters oversight standards, will affect operation of the entire security system or security products. IP represents Ingress Protection (ingress protection), protection class IP system provides a method for electrical equipment and packaging dustproof, waterproof and anti-collision extent to which the product classification. 

When we conduct security equipment selection, we must first determine that the product is suitable for indoor or outdoor, and then based on the introduction of security products provider to select a product, so it is important parameters on the product, the product will be on some parameters indicate the degree of protection standards, we are determined to this standard. Protection class that contains the two concepts, one is dustproof, the other is the water level.

IPAB wherein A represents a dustproof, B represents the water level, generally based on figures to represent the meaning of such a product. For example, a camera specification protection class IP67, indicates that the product can completely prevent dust entering and prevents flooding of water intrusion.

Test security products IP rating Standard Specification

(1) IPA 1 Method Name: Vertical dripping test

Test Equipment: dripping test device
