Brands like Samsung and Bosch are adding internal cameras to their refrigerators to help customers know what they've got at home and what they need to buy

Many of us have made a quick grocery trip on our way home from work, only to discover once we open our fridge at home that we didn't grab most of what we actually needed. ‘Shelfies' to the rescue! According to retailer John Lewis, sales of fridges with internal cameras have tripled in the last year and are growing more popular than ever.

Every type works a little differently. The Samsung Family Hub uses three cameras to capture the top, middle and bottom compartments, and will send a picture to your mobile phone every time the door is closed. The Bosch Home Connect uses two cameras and in addition to sending photos of the fridge's contents, it also sends alerts if you accidentally leave the fridge door open.

Nick Bevan, head of Product Management at Samsung Electronics, told The Daily Mail that this feature is as much about helping the shopper as it is the environment:

“It stops you doubling up and cuts down on food waste, which is a big problem. It also means that if you see something unexpected on offer, you can check to see if you have the rest of the ingredients already in your fridge to make a certain recipe, or if you need to stock up.”
