Some customer found we have Retevis RT29 4 versions on our www.retevis.com. When they order, they don’t know how to choose. Today we will have a explanation here:
UHF：Ultra High Frequency It means 400-480MHz frequency band.
UHF frequency band has a better penetration ability, it’s more suitable to use in the surroundings that has more barriers, like inside the city, inside the building, inside the rolling mountains,noisy neighborhood, etc.
VHF: Very High Frequency It means 136-174MHz frequency band.
UHF frequency band has a better diffraction ability, it’s more suitable to use in the surroundings that has less barriers, like in the farm, on the sea, on the beach, on the island, anyway, in a “open” site that has very few barriers, VHF is more suitable.
So you need first choose UHF or VHF based on your communication surroundings and terrains.
So what do you mean IP67?
IP67: What is IP67 waterproof and dustproof?
IP67 is a protection level for electronic product enclosures. IP is the abbreviation of Ingress Protection Rating, which refers to the protection capability of an interface against liquid and solid particles.
The two digits behind IP67, the first digit is the solid state protection level (its range is 0-6); the second number is the liquid protection level (its range is 0-8). The larger the number, the stronger its protection capability.
Do I need choose IP67 version?
If your communication environment is mostly outdoor， sometimes it has rainy or snowy weather, then IP67 version is better.
If you mostly communicate indoors, then no need IP67 waterproof, common UHF version is ok.
