Using Keychain Camera
I'd buy something at lazada and i have use it several times and here is the results and the quality of the pictures.
The camera is like a spy camera or is it? No one can suspect you using it but the quality is not that good yet reasonable for the very cheap price they offer online.
You can put the camera on your car keys so if there is an emergency you can use it to take pictures and videos.
The memory size of the camera is 4gb, but you can replace it if you have some memory card that is bigger than 4gb
