# Motors and PTZ

OpenIPC has support for motors on many devices through a variety of means. Many of these can be found in the [motors](https://github.com/OpenIPC/motors) repo. 

## Types of control

### Vendor binary/module

Some motors can be controlled through a binary or kernel module. [ingenic-motor](https://github.com/OpenIPC/motors/tree/master/ingenic-motor) is an example of this. Hex messages are sent to the module that in turn move the motor. [xm-kmotor](https://github.com/OpenIPC/motors/tree/master/xm-kmotor) does this as well. View their READMEs for more information on configuration. 

### UART

Some motors can be controlled through a UART TTY device. See [xm-uart.](https://github.com/OpenIPC/motors/blob/master/xm-uart/)

### GPIO

This is a simple and direct method to control a stepper motor by setting off GPIOs to a component on the board that assists in driving the motor. As long as you can probe your board and determine which GPIOs are connected to something like a ULN2803, there's a good chance you'll be able to control it.

## Configuring ONVIF

With [onvif_simple_server](https://github.com/roleoroleo/onvif_simple_server) you can easily gain access to PTZ controls through ONVIF (simple [example](https://github.com/OpenIPC/sandbox/tree/main/scripts/onvif)). Functionality will vary depending on the motor control package you use. See the server's example config in it's repo for all of the available commands.
