Hacks that can be performed by a phone camera.

Imagine you are banging the door and your friend is inside and he is not responding.

you are worried, all doors and windows are closed from inside.

you wanna see inside, you wanna know is he in danger.

just tie mobile to a stick firmly and start camera recording, when camera starts recording slowly take mobile up to the air ventilator by using maximun length of the stick.

keep mobile for few secs let the mobile record whats inside the room through air ventilator.

bring mobile down and stop recording and play the video and see whats in the room.

This would help when we need a emergency instant help.

 

If you have a small opening in window and you are not able to see inside fully, you can start recording and take mobile into the opening and move mobile 360 degree and see complete view of room.
