## Optimising resources
[Image processing components](/components/image_processing/) process the image from a camera at a fixed period given by the `scan_interval`. This leads to excessive processing if the image on the camera hasn't changed, as the default `scan_interval` is 10 seconds. You can override this by adding to your config `scan_interval: 10000` (setting the interval to 10,000 seconds), and then call the `image_processing.scan` service when you actually want to perform processing.
```yaml
# Example advanced configuration.yaml entry
image_processing:
- platform: tensorflow
scan_interval: 10000
source:
- entity_id: camera.driveway
- entity_id: camera.backyard
```
```yaml
# Example advanced automations.yaml entry
- alias: Tensorflow scanning
trigger:
- platform: state
entity_id:
- binary_sensor.driveway
action:
- service: image_processing.scan
entity_id: camera.driveway
```
