How to focus every thing in dslr (hyperfocal focus)?

Hi… We make hidden camera prank show on youtube.com/unglibaaz
I have a nikon d5200 with 18-55
And thats sufficient zoom for my shoot because we usually hide the dslr
I want to know How to do hyperfocul focus in dslr
Because every person should be in focus
The target and all the people
And thats very difficult in dslr because of dept of field focus
In simple words my question is Like in camcorder or mobile camera every think is in focus from front to back there's no dept of field or sharp focus subject
But in dslr only the subject is in focus
So how to do everythink in focus in dslr
It this possible or i need to switch to a camcorder
It will really help if its possible in anyway in dslr because i just bought it… Thanks in advance

There are lots of apps that will calculate the hyperfocal distances for you, but you really should read up on the relationship between aperture, depth of field and focal length. Fwiw, I (almost) always use a camcorder to record video and a stills camera to record stills - I'd never buy a DSLR to shoot video.
