Car Keys Micro Camera Review
hope it can help your life safe and happiness
808 #9 Camera
The #9 is one version of the 808 car keys micro camera.
It is sold by Meritline and DealExtreme and the processor seems to be a Sunplus variant.
The processor is labeled Generalplus or is potted and unlabeled.
|131031 - #9 Variant with Cyan Date Time Stamp|
|Neil reported this 808
#9 with Cyan date time stamp.
Same as the yellow #9, but the different camera module seems to show vignetting. The focal length of the lens seems somewhat longer than the #3 & the #23 I presently have. I have not managed to set up shots with exact alignment or anything like that. That is just my impression. I have not had a Yellow #9 and the Cyan variant at the same time to test in low-light. The Cyan #9 is a smeary mess but a #3 copes quite well on a dull autumn day or inside a store. In summer the Cyan #9 handles a sunny day without the crushed black & clipped white which affects the #23, MD80 and also that mystery camera I sent details of. That issue is one I wish I could compensate for.
|130703 - 808 #9 report|
sunny Greece sent me this information about a defective 808 #9
he bought October 2012. The video and images have strange
colors, probably caused by a broken connection in the internal
data path. He could not get a refund from the seller.
The PWB is labeled JH 1203E 12/04/23. Video 720x480, 30.000FPS. Audio 352.8 Kbps. Photos 1280x1024.

|130718 - #9 Report|
|Report from Neil in
I was going to write and volunteer the #9 as a candidate for the worst keychain camera based on the poor video quality. I have bought a keychain camera from two different places and both turned out to be #9s on arrival. One has the usual yellow time-stamp & the video was as poor as I have come to expect. In sunny conditions the contrast goes mad, which doesn't help the general lack of sharpness.
The other one has the usual two crystals, encapsulated CPU, No version mark on the PCB. "12/08/29-E" & "1315" on the PCB and the only marking on the camera module ribbon cable was "80". It had a Hynix SDRAM chip. The PCB is laid out like the images in the report dated 130501. The camera also displays the time-stamp in cyan and the picture quality/and exposure is much better than the first camera.
When I tested the two #9's for video quality it was done with the same micro SD card. I took a shot with one camera and then the other as quickly as I could switch the card to the other camera.
My comment on the cyan stamp #9 still stands. The JH10C camera module of a yellow stamp #9 seems to be poor. I haven't managed to focus one to be sharp yet & believe me I have tried on two different examples

|130331 - #9 report|
|Stefano in Italy has
this #9 report:
|I recently bought a
keychain camera, 5 Euros on Aliexpress, China vendor.
Unfortunately is #9.
But I have a good new. My camera is able to record videos or take still images while charging from a phone charger or even from a computer USB port.
Steps to take:
1) Shut down the camera
2) Press and hold shutter button
3) While holding shutter button, plug the camera to the charger (USB port or charger). (PC must be ON, phone charger already connected to wall plug)
4) Led will light ON. It will be steady light (mine's yellow/orange)
5) Release shutter button. the led must be steady at this time
6) Now you can record a video or take a still image as usual
7) If you press the shutdown button, you have to repeate the procedure.
This way I've been able to record 4 hours video, splitted in 30 minutes chunks.

Stefano wrote some Linux scripts. Other people could find them helpful.
They need GNU/Linux OS, ffmpeg and md5sum.
The first script acts like a player, or like avidemux: it plays/decodes the video and save the frames to a directory.
Then it checks for copied frames and calculates the rate of missing frames. This script is the slower.
The second script extracts the real frames from the video and calculates the expected number of frames.
Then you'll get the missing frames ratio ---> expected_frames/real_ frames.
He will reply to users questions about the scripts at "email@example.com".

|120825 - #9 but 640x480. JH_1203E 12/04/23|
Dávid from Austria
received a #9 from
640x480 video and 352.8 Kbps audio.
The internal label says: "JH_1203E 12/04/23".
The missing frame rate is about 18%
The AVI file data rate is about 78MB per minute.
|120410 - #9 with 352.8 Kbps audio. JH_1203E 13/12/11|
an 808 from a UK eBay seller. He received a #9 but the
audio is 352.8 Kbps (22050, 16 bit like the 808 #3). #9
cameras have been 128 Kbps. So it seems
the developer might be trying to make a #9 impersonate an #3 camera,
maybe with different firmware. The missing frame rate
measures 23%, similar to other #9 cameras.

|120219 - Setting the date time stamp|
|LM wrote me with these
instructions about setting the date time.
Simply enter the TAG.txt file on flash card and edit the numbers on it with the current date and time. Do not modify the format. Do not perform any other modifications but only rewrite de current time and date. :) That's all! Disconnect the USB cable and make a new record and verify! :)

|111102 - #9 Report|
|Shaun from Scotland
sent me this #9 report.
I have bought an 808 camera and after taking it apart have found that it is a #9. I have looked at the videos and images that it records. The videos are missing the bottom part and are scaled up to 720 by 480 with no aspect distortion. The images make full use of the image sensor and are scaled up to 1280 by 1024 with distortion, but when re sized to 640 by 480, the distortion is gone. It works with any computer as a generic webcam. I needed no drivers for it. On the webcam video feed it has "DV V2. 18B" imposed onto the video in yellow font in the bottom left corner.
|110901 - #9 JH_1103E|
Norway received an 808 #9 from DealExtreme and sent me photos and video.
The camera has the characteristics of the 808 #9 with a newer circuit board (JH_1103E). The date time stamp is a new color, cyan. Other #9 cameras have a yellow or white date time stamp.

|www.gadgets2u.net provided me a sample AVI and photos. The missing frame rate of this video sample is about 16% which is better than other #9 cameras. #9 cameras have either white or yellow time stamp in the lower right. The yellow font is a different font than used in the #3.|

|110318 - Another #9 variant|
Martin received a slightly different #9 camera.
Differences include a Chip-On-Board (potted) processor,
the photo JPG is 1280x1024 (not 1024x768).
The missing frame rate is bad at about 28%. That is about 3 times an acceptable %.
It is very interesting that potted CPU (COB) is being used. The parts count is maybe much less than other 808 cameras.
The JPG image taken by the camera looks "mottled". My guess is that the camera module is producing a lot of image noise, and the MJPEG compressor is filtering that noise, resulting in the mottled appearance in both the JPG and AVI.
The hardware ID (1b3f 0c52) matches the #9 mass storage device.

|2010 Oct 12 - #9 Processor, Generalplus, Sunplus|
101012 - Jared produced this information about Sunplus and Generalplus.
I looked up the Generalplus and Sunplus companies. They are in the same location, and have the same CEO, leading me to believe they are the same company using 2 names, both "owned" by " BEIJING SUNNORTH TECHNOLOGY CO., LTD":
Sunplus: Chairman and CEO Mr. Chou-Chye Huang, http://mcu.sunplusmcu.com/
Generalplus: Chairman & President -- Mr. Chou-Chye Huang, http://www.generalplus.com/about/0102.htm
Sunplus: Science Park, Hsin Chu, Taiwan Science Park, Hsin Chu, Taiwan
Genplus: 3F, No.8, Dusing Rd., Hsinchu Science Park, Hsinchu City 30078, Taiwan, R.O.C.
|The processor is made by
It is "GPL32080A-703A-QL091". It is part of the family of
GPL32XXX 2-bit ARM7 TV Game / Handheld Game / ELA LCD Controller.
From the product guide the GPL3XXX has 96 MHz clock, hardware MJPEG codec, SD card interface, USB interface, and other features.
This site seems to imply a relationship between Sunplus and Generalplus.

|2010 Sep 28 - #9 - An 808 #5 Syntek Variant Generalplus from Meritline|
|101006 - Jared requested a webcam driver from TGF for his Meritline 808 camera but they sent an SPCA_1528 driver that does not work.|
|100930 - Jared did some
research and noted that this camera could not be put into webcam
mode in the usual way. Jared discovered that the hardware
ID of the mass storage device is VID 1B3F PID 0C52.
This VID does not match any existing 808 camera. Existing
808 webcam drivers will not work with it because the hardware ID
VID does not match existing 808 webcam drivers.
|100928 - Raj Sent me
this detailed info about this #5 variant.
Just wanted to let you know that I received what may be a new variant of #5 from Meritline
They have it advertised as a #3 camera but the specs don't match.
The camera-mode pictures are 1024x768 with a resolution of 96dpi (horizontal and vertical) and a bit depth of 24.
The videos are 720x480, 30.000fps, bit depth of 8, and the audio is 128kbs, sampling of 8khz, and bit depth of 16.
Also, the time/date stamp is placed in the lower right hand corner and is white.
A file named "time.txt" is automatically written to a blank card when inserted with the format of
"YYYY-MM-DD HH:MM:SS" with a default value of "2010-10-01 23:59:59".
If deleted, the file reappears on the next power cycle. If modified to the correct date and time, and power cycled, it stamps the correct date and
time to the pictures.
However, if the device is power cycled again, it reverts back to the default date of "2010-10-01 23:59:59" in the "time.txt" but still displays the accurate time and date in the pictures. Pretty bizarre.
The manufacturer property shows up as "GENPLUS" and device description property shows up as "USB-MSDC DISK A".
|100926 - Christian received a
camera from Meritline described as a #3.
It is not a #3. The video quality and the missing frame rate is visibly worse than a #3 camera. The audio is worse than a #3.
It is a new variation similar to the #5 camera.
It is probably a Syntek Generplus processor.
It is mostly like the #5 because of the 720x480 undistorted aspect ratio.
It is unlike the #5 because it has1280x768 undistorted photos and 16 bit audio.
