发帖数: 461 | 17 我总结了一个记录仪的功能列表，大家看看补充一下吧:
通电自动录，断电继续记录几秒，然后停。
有内部电池，可以手动开始记录。
循环记录
至少720p的清晰度
可以当场回放
带夜视
高级一点的功能:
带碰撞感应器
带GPS，可以track走过的路
多个摄像头
其实大部分的功能手机软件都具备，甚至超越，只是每次都要放到架子上比较烦。 |

别人闯红灯造成的车祸就很有用，特别是没有证人的情况下。
有人闯红灯了，他一般不会承认，如果你幸运有人作证，不走运那就看法官怎么判了。
这是我的亲身经历，我的运气还不错，有人证，即使这样对方的保险还来恶心我。要是
当时有摄像头就更好了。

Expect Chinese quality engineering, September 30, 2011
By Steely Blue (Darien, IL, USA) - See all my reviews
Amazon Verified Purchase(What's this?)
This review is from: DOD F900LHD Full HD Car Black Box DVR Camera 1080P LCD
(Electronics)
Pros:
-It works. It supports loop recording, automatic recording upon power-on,
and a car mount - these are the only reasons why I purchased it over a
conventional camcorder. In fact, I have two of these in automated operation
- in the front and rear of my car.
-Automatic exposure control seems to work well.
Cons:
-The included user manual is not too informative. It is also written in
broken English.
-The user interface is not too friendly, but it works if you use it right.
You'll get used to it. The only time I ever have to touch is when correcting
for daylight saving time changes.
-Don't expect the best optics. With the device mounted on my windshield, I
would have liked for the video to be good enough for me to read the license
plates of cars, but the only plates I can read are those of the car
immediately ahead of or behind me, and only if the light is right. I guess
not all HD camcorders are the same.
-The video capture angle is reduced when recording at 1080p. "Wide angle" is
available only with 720p. Personally I have been recording at 1080p instead
so I have a better chance of capturing readable license plates.
-The video is written to files with the MOV extension. This is less
preferable than say MP4, etc.
Bugs:
-Loop recording mode seems like it has a software bug. It breaks the video
file even though the specified period of time has not elapsed for a
particular video. I believe it does this because it counts time cumulatively
(this would be the wrong way to do it), rather than resetting the count at
the start of every file. If this theory is correct, and I'm not a 100% sure,
but if it is, then in practice, this should be less of a concern if you
have a large video card and have selected the largest available loop time.
-In automatic recording upon power-on mode, if the car/power is turned on
and then turned off before the recording has had a chance to begin, the
right thing to happen would be for the device to shut down, but this doesn't
happen. Instead, the device starts and idles displaying the current view on
the screen. If the device is then ignored, it may technically drain its
entire internal battery and lose all its non-default settings thereafter.
You therefore never want to leave it indefinitely in this state. To reset
this state and have the device shut down (or begin recording), restart the
car/power, wait till recording begins, and then turn off the car/power as
necessary. Alternatively, manually power the device off using its power
button. To avoid entering this state altogether, always make sure that you
allow recording to begin before you turn the car/power off.
Comments:
-The file format is MPEG-4 QuickTime. The video encoder is Ambarella AVC
with a variable bit rate of about 8000 Kbits/s at 29.970 fps. The audio
encoder is Ambarella AAC with two channels and a constant bit rate of 128
kbps. The file can be played with VLC media player. If your computer is old,
just play the file at a reduced play speed, e.g. 0.67x or 0.5x.
-Be sure to check the website dod-tec.us for more info about this model
before purchasing it.
-I picked this over the GS600 model because I intentionally did not want GPS
recording, and I wanted an integrated display.
-In addition to SDHC cards, an SDXC card is also technically usable, but a
128GB SDXC card was formatted by the device to only a 26.96GB FAT32 volume,
as if it were a 32GB card. I manually formatted this card to have a ~128GB
FAT32 volume, but the card was then not recognized as being usable by the
device. I currently use a 32GB SDHC card.
-I'm currently using it in 45 minute loop recording mode with automatic
recording upon power-on.
-FAT32 has a max file size limit of 4GiB. Given the max observed data rate,
a 45 minute file can typically be expected to be no larger than about 2.8Gib
, which is safely less than the limit.
-There was an unrated seller on eBay advertising this item for a much lower
price, but the seller turned out to be fraudulent. Don't fall for such scams.
I will update this review if I have more to add. If you know of an
alternative car camcorder that you believe is superior, please let me know!

现在市场上的低价记录仪都是1/4" CMOS，720p也是差值出来的。而且这种清晰度根本
做不到实时压缩和存储。
相对于车灯，记录仪上的LED就是渣
带这个功能起码要100+了
