| 131009 - 808 HQ30 Battery Discharge Time Tests |
| Dirk in Germany did these
battery discharge tests. The camera is configured to
record video in 10 minute AVI files. Battery test starts
charged. Summary: The battery lasted 47 minutes and produced 5 AVI files (6.65GB) at about 141MB per minute. The battery lasted 41 minutes and produced 5 AVI files (5.93GB) at about 145MB per minute. ========== 131009 - I just finished another "battery draining" test, this time it was fully loaded. I got 47 Minutes and ~10 seconds (first four files varying between 9:58 minutes and full 10:00 minutes). The last file is closed gracefully and correct after 7:18 Minutes. This resulted in 6.65 GByte video files on the SDcard. 131008 - The battery was used very little before starting the test. 41 Minutes of recording done, last file closed and saved correctly. I set the camera to 10 minutes splitting, the files were ~1.39 - 1.45 GByte each now in a "stationary environment". ~41 minutes take up 5,93 GBytes (summed up by Windows Explorer for all 5 files). Last file has 208 MByte. As you can see in the "Video: MJPEG ...."-framerate, there is a little frameloss, also the framrate would be 29,97/30fps. Upon file close and heading to the next file a few frames get lost. Merging such files into a single one results into tiny jumps and noises at that spot. The battery isn't completely drained. The cam starts up afterwards again. I don't dare draining the battery completely now because that can damage a LiPo battery massively (and I don't have the USB cable for the HQ30 with me here at work). Data from the snippets: 1) Overall bit rate : 20.7 Mbps Duration: 9mn 59s Frame rate: 29.970 fps (Video: MJPG 1280x720 29.95fps [Video]) 2) Overall bit rate: 20.8 Mbps Duration: 9mn 58s Frame rate: 29.970 fps (Video: MJPG 1280x720 29.968fps [Video]) 3) Overall bit rate: 20.6 Mbps Duration: 9mn 58s Frame rate: 29.970 fps (Video: MJPG 1280x720 29.969fps [Video]) 4) Overall bit rate: 20.0 Mbps Duration: 9mn 58s Frame rate: 29.970 fps (Video: MJPG 1280x720 29.969fps [Video]) 5) Overall bit rate 20.4 Mbps Duration: 1mn 25s Frame rate: 29.970 fps (Video: MJPG 1280x720 29.974fps [Video]) |

2013/07/03 12:13:14 photo=3M frequency=60 tv=p timestamp=0 workmode=1 cycle=5 • Date and time are self explanatory. • photo megapixel can take the values 1m, 3m or 5m (only for 1m the image doesn't get scaled). • frequency is the one of the flicker filter (50 or 60 Hz). • tv type is for TVout (via special cable, for "live" FPV), p=PAL, n=NTSC. TVout can cause more battery drain. • timestamp is off by default, can be switched on: 0 (off), 1(on). • workmode is the mode the camera is in after powering it on: 1= 1280x720 (30fps), 2=640x480 (60fps), 3=Photo, 4=Sound recorder, 5=Dashcam mode (when SDcard is full, delete oldest file). • cycle is the time in minutes after which the current file is closed and a new one opened. 2, 5 or 10 minutes are available. |

Objective Data All metrics are subject to change |
|
|
Metrics taken from a sample outdoor-light AVI. Video Wrapper: Video: AVI. Overall bit rate : 23.1 Mbps for an outdoor-light sample, about 173 MB per minute. The data rate varies; you have seen the absolute maximum there. I observed data rates between 70-120 MByte/minute. In darkness, the data rate drops significantly, in bright areas and with much movement, the codec has no chance to "compress movement" and thus produces higher bitrates. Video Stream: MJPG, Bit rate : 22.9 Mbps, 1280x720, 16:9 (1.78), FPS 30.151. Audio Stream: PCM. Bit rate : 176.4 Kbps. Sampling rate : 11.025 KHz. Bit depth : 16 bits. Interleave, duration : 93 ms (2.80 video frames). Video filename format: SUNP0001.AVI Photo filename format: SUNP0001.JPG ---------- Other Features SPCA12627A processor. OV9712 image sensor. The missing frame rate seems to be about 0% (best). Date time stamp can be disabled or enabled. Generic webcam mode. No driver needed. Uses SDHC card up to 32GB. Composite video output with optional cable. Can be externally powered with optional cable. Can record audio only. Flight recorder mode, 5 minutes segments, then overwrites. Battery LiPo 502035 (5.0 x 20 x 35mm). Four LED indicators in red, green, yellow and blue. The 8 pin connector on the HQ30 is not a standard USB connector. Label the cable HQ30 and don't use any other 8-pin cable with the HQ30. |
