CCTV

The Raspberry Pi has made many different types of projects possible and one that’s popular is CCTV. The official Pi Camera, along with the Pi offer a low cost, high quality and low-power project you can build quickly. In this project, we used motion to stream our webcam to a webpage, but motion can be used to search for motion and stream as well, eg we can record a video stream to a local or cloud device which will be triggered by a burglar, baby or Jack Russell terrier. Add a Passive Infra Red (PIR) sensor to this code, such as the one used in our delivery watch project, and you have a powerful application that can alert you to incidents and record the evidence. Another great application to use with a webcam is Zoneminder ( which also works with the Raspberry Pi. Using Zoneminder, you’ll be able to monitor multiple streams and set up zones which will trigger an alert, eg a zone drawn around a door frame would trigger if a person used the door, but the surrounding area wouldn’t be monitored for activity.
