Building a DIY Raspberry Pi security camera is much easier than it might sound thanks to open-source security camera software. We use several such cameras placed around the house, as part of our DIY CCTV security camera system.
One such camera is placed at the foot of our driveway at the cabin. It uses the security camera software described in this post to detect cars. Then, it uses our alert system to notify us when a car comes up the driveway. Or when people are at the door.
But first, we need a high resolution camera to hook up to the Raspberry Pi.
High Definition Security Cameras
One advantage to using a Raspberry Pi security camera is the ability to choose from many different camera options. There are “official” cameras for the Raspberry Pi, which connect using a ribbon cable. The original v1 option provides a 5mp security camera (1080p). The v2 8mp security camera costs almost three times as much. But even a high resolution security camera is not much use at night.
The best night vision security camera(s) need to automatically switch between day and night mode. The basic NOIR models cannot do this, and therefore will look tinted during the daytime. Unfortunately, most of the day/night cameras are 5mp. Still, as I showed in the DIY dashcam post, these cameras are good enough for our needs.
