What is timer cam?

Timer cam is a feature found in some camera devices that allows users to set a timer before taking a picture automatically. This is especially useful in situations where the photographer wants to be included in the shot but doesn't have anyone else to take the picture. The timer cam usually allows users to set the timing for picture-taking, ranging from a few seconds to several minutes, depending on the camera. It is a common feature in smartphone cameras and point-and-shoot digital cameras. In addition, some advanced cameras also offer remote control options that enable users to control the camera from their smartphone or tablet, allowing them to use the timer function quite extensively.
