# Send the open signal to the camera

`POST https://api.parklio.com/v2/lpr-cameras/{id}/state`

This enpoint sends a OPEN operation to the camera. The open
      operation will trigger a signal on the LPR Camera output which can be
      used as input into any supported hardware, triggering an operation on the
      device. For example, if the LPR Cameras output is connected to a Gate
      input, it will trigger a change of state on the Gate.

**Auth:** `Authorization: Bearer <token>`
