Meraki IoT Script Collection: MV Cameras and MT Sensors

This script collection helps you getting started to get data out of Meraki MV cameras and Meraki MT sensors from the Cloud and via MQTT locally.

Prerequisites & Installation

(1) Python dependencies: Install on your own the required Python libraries which are different for each script.

(2) Running Mosquitto MQTT broker (for MQTT scripts only)

docker pull ecplipse-mosquitto:1.6
docker run -p 1883:1883 eclipse-mosquitto:1.6

(3) Setup MQTT broker on the Meraki dashboard (for MQTT scripts only.

Get historical sensor readings from MT sensors

Script: mt_get_historical_sensor_readings.py

Get historical sensor readings based your defined timespan and granularity.

Get latest sensor reading from MT sensors

Script: mt_get_latest_sensor_reading.py

Get the latest sensor reading from your desired sensor.

Machine learning inference with RTSP stream

Script: mv_custom_ml_model_inference_tensorflow.py

This script shows how you can get the live video stream from the MV camera and check the received video frame against your ML model built with Keras/Tensorflow.

In this example, the image will be cropped at first and then predicted against the model.

Getting MQTT data from MV camera:

Script: mv_get_mqtt_data.py

Connecting via paho MQTT client to the MQTT broker (e.g. Mosquitto) and getting all plain MQTT topics / sensor data from the MV camera.

Try out this fire alarm video for the MV camera to record the audio and detect the fire alarm.

Sample Output:

Lux: 7.0
In zone Zone_Right are 1 person(s).
ALARM! fireAlarm
Lux: 7.0
Lux: 7.0
Audio Level (dB): -45
Lux: 7.0
Lux: 7.0
In zone Zone_Right are 1 person(s).
ALARM! fireAlarm
Lux: 7.0
Lux: 7.2
In zone Zone_Right are 1 person(s).
Lux: 7.0
Audio Level (dB): -42

Get RTSP stream from MV camera

Script: mv_read_rtsp_stream.py

Simply receive the RTSP video stream from the MV camera with OpenCV.

Get camera snapshot when door sensor got triggered

Script: mv-mt_get_snapshot_when_door_was_opened.py

Specify the serial number of the MT door sensor and also the serial number of the MV camera where the snapshots should be taken.

The snapshots will then be downloaded, the name of the .jpeg file is the UNIX timestamp.
