How does Canon SLR take a selfie without a remote control?

There are two methods (excluding wireless cable release):

1, the SLR camera can choose self-timer/remote control in driving mode, and can set the camera delay 10 second or 2 seconds to take self-timer, that is, after pressing the shutter, the camera will wait 10 second or 2 seconds before starting shooting.

2. If the SLR camera has built-in WIFI, you can remotely control the camera shooting through special software on your smartphone. This self-timer is very easy to use, you can set camera parameters through your mobile phone, and it is also convenient to view and compose.
