Motion Controlled Motorised Camera Base:
The idea behind AutoCam is to provide 360 degree rotatable camera base which will monitor and rotate the camera to the intrusion detected (Change in human movement) regions as instructed by the sensors.

Project summary

Project ’AutoCam’ is a security camera module which applies the motion detection technology. It consist of a camera module with a motorized base and 5 PIR sensors at various angles to detect human presence and movement. On detecting any movement in the surrounding environment the camera in the module rotates to the respective direction. The client will receive the notification in the phone making him aware of intrusion in his absentia. MQTT protocol is used to send the notification and live streaming allows the client to outlook the unwelcomed movement and take a note once notified.

Project Content

AutoCam Model


  • Control the movement of the servo motor in light of the motion identified by the PIR sensors.
  • Set the camera module as indicated by the servo motor.
  • Send notice and notification link to the client’s phone using MQTT.
  • Live stream the video over the net accessible in the phone, computer or any electronic gadget connected to Internet.


The 5 PIR sensors and Servomotor are connected to the WizFi310 which is mounted to the wizwiki-W7500.  The camera is placed on the Servomotor which enables the camera to rotate. the camera is connected to the Raspberry Pi to achieve live streaming.  

Design Modules:

1) Sensing Module:      

  • PIR motion sensors are connected to Wizwiki-W7500 to detect any movement in a 360º radius.
  • The PIR acts on intrusion detection and sends digital data to device (’1’ for object presence).
  • PIR has to be calibrated with empty room before so that it indicates once a presence is detected.

2)Surveillance Module:

  • The video live streaming was achieved using the I-Ball webcam and raspberry pi3.
  • The raspberry pi3 was configured to the webcam and the live streaming was achieved using the motion package available in the pi3 library.
  • The live streamed video was available in all devices connected to the local network.

3)Control module: 

  • The servo motor is attached to the stand where the camera sits, and rotates the camera to align with the active PIR sensor. Once the motion is detected, a servo motor rotates the camera base to a point in that direction.

4)Monitoring module:

  • Notification was sent using MQTT protocol and was tested at client’s end. The localhost link was provided in the app to connect to live streaming.

NOTE: The complete architecture and working of the project with demo is explained in the video . The link of the video is provided below.
