outdoor security camera?




csm


I want to set up a security camera outside of my house. However i want to have it mounted on a tree in my yard rather than on the house itself. Does anyone know of a camera that i could mount on a tree and still have function well. Also i would dont want to have to run a cable to my house, so if the camera could save to a memory card in the camera that would be great. It would also be great for the camera to work in the dark and/or to have a motion sensor that only records when it senses movement. picture quality is important as well

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...
