Home surveillance and use of microphone to trigger camera - Raspberry Pi Forums

-

hello there

have used wonderful recipe making home surveillance system @ home http://www.pyimagesearch.com/2015/06/01 ... nd-opencv/.

in takes photos every time there motion in front of camera. following. ideas how accomplish ?
  • use usb microphone trigger camera start
  • i off course record laud sound alarm system , use sound triggering

hi,
interested in similar project (perhaps). want listen sound , trigger following once threshold has been reached:
1- record 1 second sample
2- start capturing images every second
3- perform fft , compare fft of several possible sources
4-save sound sample, fft image, camera images , possible source
5- keep doing above until sound level drops below threshold.

if have ideas on of these steps happy hear them. figure place start sound triggering

hello everyone, name kedi.. make system connecting raspberry pi 2 , arduino uno arduino adc of 1 dust sensor sharp gp2y1010au0f , 4 gas sensor. want show decision of air quality system in running text @ p10 16x32 led dot matrix display. in raspberry pi 2, connect p10 pins in gpio25, gpio12, gpio16, gpio13 & gpio26. now, i'm finish circuit , don't know must connect p10's vcc & ground (red & black wire). can me? , code in python controlling p10(1r)-v706 dot matrix?.. regards, kedi i can't python code (did mine in basic on risc os) regarding power, panels each require 2.5a, you'll need separate supply them. if attempted power them pi, pi's polyfuse blow immediately. alternatively, use supply capable of giving 10a supply both panels , pi. raspberrypi

hi, thank help. question simple: how convert raspistill data opencv processing. code: select all def capture(settings, width, height): command = "raspistill %s -w %s -h %s -t 200 -e bmp -n -o -" % (settings, width, height) imagedata = stringio.stringio() imagedata.write(subprocess.check_output(command, shell=true)) imagedata.seek(0) im = image.open(imagedata) buffer = im.load() imagedata.close() return im,buffer code: select all image1, buffer1 = capture(camerasettings, testwidth, testheight) cv2.imshow('image',image1) want use different opencv processing techniques, before need know doing wrong. bests svato raspberrypi
