When choosing an intercom, speaker, or door phone for an outdoor area, you will often see codes like IP66 and IK10. These are not just marketing numbers, but durability standards that determine whether a device will survive at your location.
What does the IP rating mean?
IP (Ingress Protection) has two digits. The first is resistance to solids and dust (0 to 6), the second to water (0 to 9). IP66 means fully dust-tight (a 6) and resistant to strong water jets from any direction (a 6). IP65 is similar but for lighter water jets, and IP67 even survives temporary immersion.
What does the IK rating mean?
IK (Impact Protection) measures resistance to physical impact, from IK00 to IK10. IK10 is the highest level, resisting a fairly large impact energy. This matters for public or unsupervised areas where a device could be a target for vandalism.
Why it matters for your choice
Fanvil outdoor devices like the A11/A12 intercoms and the A233 horn speaker are designed with high ratings (IP66, and IK10 for the intercoms) plus a wide working temperature range. Choosing the right rating ensures the device is not quickly damaged by weather or impact, lowering the total cost of ownership.
Match it to the install location
For a sheltered indoor area, a standard rating is enough. For gates, parks, or open parking, prioritize IP66 and IK10. If in doubt, our team can help match a device rating to your site conditions before you buy.
