Hi quanghieu,
If you are talking about a wireless spy camera that is battery powered, as I remember tech related to this, this only last few hours around 2hrs more or less in operation. It is because of the capacity of battery that is quite limited considering its size. There are some that last almost 24hrs but kinda bulky with the energy storage and some components. You may consider the possible setup you are trying to build.
Try to check spycams online, same to this one link->

Hope it helps.
Best,
