```
When using CPU detectors, you can add a CPU detector per camera. Adding more detectors than the number of cameras should not improve performance.
## OpenVino
The OpenVino detector allows Frigate to run an OpenVino IR model on Intel CPU, GPU and VPU hardware.
### OpenVino Devices
The OpenVino detector supports the Intel-supplied device plugins and can specify one or more devices in the configuration. See OpenVino's device naming conventions in the [Device Documentation](https://docs.openvino.ai/latest/openvino_docs_OV_UG_Working_with_devices.html) for more detail. Other supported devices could be `AUTO`, `CPU`, `GPU`, etc.
```yaml
detectors:
ov_detector:
type: openvino
device: GPU
```
### OpenVino Models
The included model for an OpenVino detector comes from Intel's Open Model Zoo [SSDLite MobileNet V2](https://github.com/openvinotoolkit/open_model_zoo/tree/master/models/public/ssdlite_mobilenet_v2) and is converted to an FP16 precision IR model. Use the model configuration shown below when using the OpenVino detector.
```yaml
model:
path: /openvino-model/ssdlite_mobilenet_v2.xml
width: 300
height: 300
input_tensor: [B, H, W, C]
input_pixel_format: "bgr"
labelmap_path: /openvino-model/coco_91cl_bkgr.txt
```
