### Connect to ONVIF Device

Source: https://github.com/use-go/onvif/blob/master/README.md

Establishes a connection to an ONVIF device using its IP address and port. Requires specifying the device's network address.

```go
dev, err := onvif.NewDevice(onvif.DeviceParams{Xaddr: "192.168.13.42:1234"})

```

--------------------------------

### Call ONVIF Service Method

Source: https://github.com/use-go/onvif/blob/master/README.md

Executes an ONVIF service method on a connected device. Requires the device object, authentication, and the defined data type for the method.

```go
createUsers := device.CreateUsers{User: onvif.User{Username:"admin", Password:"qwerty", UserLevel:"User"}}
device := onvif.NewDevice(onvif.DeviceParams{Xaddr: "192.168.13.42:1234", Username: "username", Password: password})
device.Authenticate("username", "password")
resp, err := dev.CallMethod(createUsers)

```

--------------------------------

### Authenticate ONVIF Device Connection

Source: https://github.com/use-go/onvif/blob/master/README.md

Connects to an ONVIF device with authentication credentials. This is necessary for services requiring user login.

```go
device := onvif.NewDevice(onvif.DeviceParams{Xaddr: "192.168.13.42:1234", Username: "username", Password: password})

```

--------------------------------

### Define CreateUsers Data Type

Source: https://github.com/use-go/onvif/blob/master/README.md

Defines the data structure for the CreateUsers function in the ONVIF Device Management service. It requires a User object with username, password, and user level.

```go
createUsers := device.CreateUsers{User: onvif.User{Username:"admin", Password:"qwerty", UserLevel:"User"}}

```

--------------------------------

### Define GetCapabilities Data Type

Source: https://github.com/use-go/onvif/blob/master/README.md

Defines the data structure for the GetCapabilities function of the ONVIF Device service. The 'Category' parameter filters the capabilities returned.

```go
capabilities := device.GetCapabilities{Category:"All"}

```

--------------------------------

### Define GetServiceCapabilities Data Type

Source: https://github.com/use-go/onvif/blob/master/README.md

Defines the data structure for the GetServiceCapabilities function of the ONVIF PTZ service. This function does not accept any arguments.

```go
ptzCapabilities := ptz.GetServiceCapabilities{}

```
