Raspberry Pi Security Infrared Camera (Python Edition)

Infrared security camera installed in my home It is a memorandum when it was created. (The content of the initial introduction is quite different from the current one)

[Things to use]

Raspberry Pi 2 Model B: Amazon 5,562 yen Infrared camera NoIR Camera Board 790-2811: Amazon 4,590 yen Pyroelectric motion sensor: Akizuki Denshi 400 yen Red LED (3mm): Akizuki Denshi 10 yen Carbon resistance (220kΩ): Sengoku Densho 16 yen

[Prerequisites]

・ "RPi.GPIO" has been introduced ・ Camera is already connected to the CSI camera port -The camera must be enabled in "raspi-config" -The VCC and GND terminals of the pyroelectric motion sensor have already been connected. The OUT terminal is connected to any GPIO (No. 5 is used here) ・ LED for sensor detection confirmation is connected (Here, connect to port 6 with a resistor in between)

[Camera operation check: command]

Still image $ raspistill -o test.jpg 　 ** Video ** $ raspivid -o test.h264

[Python camera control environment]

$ sudo apt-get update $ sudo apt-get install python-picamera

[Still image test of Python alone]

StillTest.py

# coding: utf-8

import picamera
import time
 
camera = picamera.PiCamera()

camera.led = True
camera.start_preview()
time.sleep(3)

camera.capture('test.jpg')

camera.stop_preview()
camera.led = False

camera.close()

[Video test of Python alone]

MovieTest.py

# coding: utf-8

import picamera
import time

camera = picamera.PiCamera()

camera.led = True
camera.start_preview()

camera.start_recording('test.h264')
camera.wait_recording(5)
camera.stop_recording()

camera.stop_preview()
camera.led = False

camera.close()

[Sensor test of Python alone]

SensorTest.py

# coding: utf-8

import RPi.GPIO as GPIO
import time

SLEEP_TIME = 1
INTAVAL_TIME = 1

GPIO.cleanup()
GPIO.setmode(GPIO.BCM)

SENSOR = 5
GPIO.setup(SENSOR, GPIO.IN)

LED = 6
GPIO.setup(LED, GPIO.OUT) 

intaval = time.time() - INTAVAL_TIME

while True:
#	print GPIO.input(SENSOR)
	GPIO.output(LED, GPIO.LOW)

	if( GPIO.input(SENSOR) == GPIO.HIGH ) and ( intaval + INTAVAL_TIME < time.time() ):
		intaval = time.time()
#		print "!! Detection !!"
		GPIO.output(LED, GPIO.HIGH)

	time.sleep(SLEEP_TIME)

[Python sensor & camera cooperation test (still image)]

StillSensorTest.py

# coding: utf-8

import datetime

import picamera
import time

import RPi.GPIO as GPIO
import time

SLEEP_TIME = 1
INTAVAL_TIME = 1

GPIO.cleanup()
GPIO.setmode(GPIO.BCM)

SENSOR = 5
GPIO.setup(SENSOR, GPIO.IN)

LED = 6
GPIO.setup(LED, GPIO.OUT) 

intaval = time.time() - INTAVAL_TIME

camera = picamera.PiCamera()

while True:
	if( GPIO.input(SENSOR) == GPIO.HIGH ) and ( intaval + INTAVAL_TIME < time.time() ):
		intaval = time.time()

		GPIO.output(LED, GPIO.HIGH)

		camera.led = True
		camera.start_preview()
		time.sleep(1)

		NowTime = datetime.datetime.now()
		camera.capture(NowTime.strftime("%Y%m%d_%H:%M:%S") + '.jpg')

		camera.stop_preview()
		camera.led = False

		GPIO.output(LED, GPIO.LOW)

	time.sleep(SLEEP_TIME)

[Remaining memorandum]

・ Sensor detection time stamp (Python → MySQL) -Store the image save destination in the date folder (Python → File) ・ Camera control from PHP, refer to DB & image, execute Python 　（PHP → DB or Python or Command or File） ・ Control and reference from the outside with a smartphone app (JavaScript → PHP)
