I would like to record videos using this code:
RecordIntervalTime = 30*60 # 30 min def camRecord(): with picamera.PiCamera() as camera: camera.resolution = (640, 480) camera.framerate = 24 camera.rotation = 90 camera.annotate_background = picamera.Color('black') camera.annotate_text = dt.datetime.now().strftime('%Y-%m-%d %H:%M:%S') camera.annotate_text_size = 16 date_string = time.strftime("%Y-%m-%d_%H-%M") device_name = socket.gethostname() # device (sensor) name print('Start recording with' + device_name + '_' + date_string) camera.start_recording('/home/pi/' + device_name + '_' + date_string + '.h264', quality=20, bitrate=2*1000000) start = dt.datetime.now() while (dt.datetime.now() - start).seconds < RecordIntervalTime: camera.annotate_text = ' (' + device_name + ') ' + dt.datetime.now().strftime('%Y-%m-%d %H:%M:%S') + ' ' camera.wait_recording(1) camera.stop_recording() print('end recording') time.sleep(1) if __name__ == '__main__': while True: print('Recording start') camRecord() time.sleep(10)
My intention is recording the videos with 30 minutes interval until running out of battery. When I conducted an experiments with 10 sensors and the code, there are different results of the recording. For example, while one device recorded videos from 9:00 to 14:00 (not the time of running out), the other recorded that from 9:00 to 24:00 (the time of running out, I would like to make that).
Do you think that the differences from the code?
