A rolling shutter is a type of image capture in cameras that records the frame line by line on an image sensor instead of capturing the entire frame all at once. The rolling shutter sensor scans from the top of the image to the bottom, so the top of the frame is recorded slightly earlier than the bottom.

A roller shutter, security shutter, coiling door, roller door or sectional overhead door is a specialized type of door or window shutter consisting of multiple horizontal slats, bars, or web systems interconnected through hinges. The mechanism involves lifting the door to open it and lowering it to close.

Roller shutters, which can be fitted onto windows or doors, provide excellent protection from intruders. First, they prevent intruders from peeking into your house or building to see any valuables lying around.
