Using a Sick WS15-D1130 Infrared Diode pair to act as a hardware motion detection sensor for Zoneminder. Also testing out an Omrom photo electric sensor, the E3F2-R2C4. This is a tripwire alarm sensor. When the beam is blocked, the alarm is activated.
You can not select more than 25 topics Topics must start with a letter or number, can include dashes ('-') and can be up to 35 characters long.
