How to make Human Detection Security camera with under 1$ Human Detection Senser, 2$ USB Webam & Raspberry Pi





and Raspberry Pi connected to Internet,



You can make Web Base Security Camera System as followsing:


PIR Sensor

There are many type of Human Detection Sensor, some of these watching infrared light ray and cache shutting out of this, or some these using Millimeter-wave radar.
PIR(Passive Infrared Ray) Sensor is on of these Human Detection Sensor which watch the change of thermal infrared emitted from hot object like Humans, Birds, and Mammals.

The sensor consist of lens for thermal infrared (white plastic tip in the picture below) and detector device.

Both parts are inexpensive parts and detector is low current consumption parts.
So, the advantage to use PIR sensor for Human Detection is:

- Inexpensive
- Low current consumption

How to setup

Step 1. Get account of MONITOR™ and your view_id


On your Web browser, Sign up to MONITOR™, then you can seen following display.



Keep the "view_id" shown in the display, you are setting your Raspberry Pi to take Camera Image & send it to the view.



Step 2. Install & setup View software in your Raspberry Pi.

The Software is available here. Install & it on your Raspberry Pi as following the steps of 1,2,3,4, and 6 (without 5) here. Then PIR Sensor and WebCam are set up to take Image and send when someone is detected.

Please note that you shoud use the view_id which you get at last step, as parameter of setuid.sh command.



Step 3. Connect PIR Sensor to Raspberry Pi.




HC-SR501 has 3 of GPIO PIN for Vin, Signal, and GND. Connect each pin by Female to Female Jumper Cables as:

- Vin and RPi 5V
- Signal and RPi GPIO18(BCM)
- GND and GND

Please refer following pictures:

In case, you can adjust sensitivity and duration by rotary switch as follows:


Step 4. Setup your Raspberry Pi & webcam.


This webcam has a useful clip,



So you can setup these easily.



After Raspberry Pi power on, View software running on the Raspberrry Pi, send Camera Image to the MONITOR™ service at 5 minute interval
On your Web Browser, MONITOR™ keep refresh the display with latest Camera Image.
