Affordable Locksmiths in Kensington has Bolt Buddies. You can buy them and install them yourself if you'd like. Added bonus - it's next to Chicken on the Way...

It's all going to depend on the underlying door and quality of install so I'd take the battering ram video with a grain of salt.
Don't forget security film for glass areas on the ground floor that are vulnerable (ie sidelight for your door which get smashed and then they reach around to undo the deadbolt)
