Using Camera Output Power

By: Brian Rhodes, Published on Jul 25, 2013

Do you realize that your camera can power and integrate PIR sensors, accelerometers, lights, sirens and strobes?

Camera input/output ports make direct integrations with other devices simple. Even though camera output voltages are modest - less than 5 VDC, they allow direct connections with components like alarm sensors, lights, strobes, and even high voltage machinery. In this note, we look at camera output power and examine its usefulness in security designs.
