It is not going to work if you try to set it up somewhere where there is no power source available. Because of the way that they work though they can be moved around quite nicely without the need to worry about that.
Some wireless doorbell cameras are also equipped with "panic" buttons that can be pressed if there is trouble. This is great for a wide variety of reasons. The first thing is that it helps to protect the wireless cameras from being accidentally disabled. Panic button operations are also something that people who have a home alarm system in place would typically want to have.
Something else to consider when looking at wireless doorbell cameras is the audio. If the owner or user wants to have some added audio features to their system then that can be done as well. For example, they can record the incoming signal and then play it back later. It is even possible to get systems that allow you to use your voice over the system.
