I need help in selecting the right TVS diode. I am working on a home security system with a D-Link DCS-5222 camera.
I have built an IR LED array to provide night illumination. The IR LED array is powered by 12VDC and uses about 1000mA. I want to use a relay to power the IR LED array only when motion is detected. The camera had DI/DO pins. The user manual has some instructions about usin the DO pins with external relay. See below.
I am seeking help in selecting the right diode and relay. Any help will be greatly appreciated.
