State of the TELEMETRY object | Description of the object state |
LOCKED—locked | Control of telemetry Telemetry control is locked with some priority. It is forbidden to control telemetry with a priority lower than the specified when locking one during the lock time (see the table above) |
UNLOCKED—unlocked | It is allowed to control telemetry with any priority |
Examples of using reactions of the TELEMETRY object:
Set autofocus when video camera is armed.
| Code Block |
|---|
OnEvent("CAM","1","ARM")
{
DoReact("TELEMETRY","1", "AUTOFOCUS_ON");
} |
Rotate video camera to the position specified in the first preset with the relay enabled.
| Code Block |
|---|
OnEvent("GRELE","1","ON")
{
telemetry_id= GetObjectParam("CAM","1","parent_id");
DoReact("TELEMETRY","telemetry_id","SETUP","GO_preset<1>");
} |
Record the patrol route for Camera 1 corresponding to the PTZ device 1.1. The route consists of two points, such that to go from point 1 to point 2, you need to rotate the camera to the left at speed of 6 for 2 seconds. Patrolling must be performed at speed of 10. The time at each point of the route is 25 seconds. It is supposed that when the program is started, the camera is set to the position corresponding to the first point of the route.
