I am planning to install (Security Camera Wireless) outdoor.
1- Is there something call (UHV).
2- What kind of product should I get that doesn't be affect with other frequencies (mobile, radio)?
Answer
For wireless stuff, it would normally be "UHF". Typically this is for good audio equipment. UHF video is still used for television stations and you would need to be licensed even if only low power.
There are only two consumer wireless video methods:
1) shared band in the 2.4 GHz environment.
2) wifi (wireless compute local area network)
Both can get interference from other sources. If you want no chance of wireless interference, then you need to use a wired camera. Also, remember that "wireless" generally means only the video (and audio if the camera has a mic) signal is wireless - you still need a wire for power unless you set up some sort of battery and solar recharge equipment.
You want cameras that are rated for outdoor use... Do they need to have "night vision"?
Are you just monitoring the video?
How many cameras?

If you are recording, are you looking at a multi-channel DVR

or are you turning a computer into a multichannel DVR?
If the power goes out, are you expecting this camera system to continue working? What are your battery back-up plans?
There's more, but this is a start...

Answer
It depends on the requirements. But your question is confusing. IP (Internet Protocol) is merely the network connection the camera has. Usually, an IP camera - for home use - is not "outdoor rated". Some are... Usually, the IP camera has nowhere to store the video, so a video server or dedicated computer is required if the video needs to be stored.
A "dome camera" is a camera in a dome. It can be IP or analog. If it is an IP camera, then the above paragraph applies. If it is an analog camera, it will need some sort of connectivity to a DVR for video storage and the DVR can be connected to the computer network.
We don't know:
what computer network might be available;
whether you need outdoor rated cameras;
how long - if at all - the video storage needs to be;
whether computer or smartphone access is needed... and lots more.
Without this information, selecting *best* is impossible.
