MD-80 Camera
MD-80 tear down
The MD-80 camera electronics are similar to the 808 car keys micro camera.
I don't review the MD-80.  There might be many versions. 
Some are similar to the 808 #3.

I get some email tips and I pass them along here.
Please don't ask me questions about the MD-80.  I don't have one.




      
140108 - Report - MD80 like the 808 #19
Franco from Italy sent me this information about his MD80 with electronics like the 808 #19.

----------------------------

I bought a MD80 Mini DV camera from eBay. Searching on Internet  I found your site that it seems to me the best on information about this class of cheap cameras. So I write to you just to share my findings.  

Looking in your table of 808 cameras, it seems a #19 model. Attached is  a frame taken from video that shows the time that is very close, if not  the same, as show as #19.
 

The time set is identical.
 

The AVI looks  like in your description. I was able to import in virtualdub using  commands File Open and choosing Direct Show as format (I have the  plugin). If you open normally you obtain black frames and virtualdub  doesn't play it, like you described.
 

Audio is like your description,  noisy whit a slow card, without noise with a faster card.
 

I opened it  to see the internals.
 

Processor is labeled A618323.1 1223 instead of  A616408.1 1225 that is described in your #19 page. I found in Russian  forum (http://www.taker.im) other similar processors like A618321.1,   A625853.1 for the same camera. I was unable to understand who is the  producer. Google and Bing where not my friends, maybe I have to use a Chinese search engine. USB give me this  USB\VID_1908&PID_3281&REV_0100&MI_02, in USB.IDS i found that 1908 is  GEMBIRD that has only one PID, 1320. So no usable information from it. 

There is only one crystal but RTC works also when the camera is off. The SPI flash is a eight pin Winbond 25Q40B

the mcu is:  AX3231 - 32-bit Video MCU


AX3231 is a highly integrated single-chip digital video microcontroller with a high-performance 32-bit RISC MCU and a dedicated image processor. It supports video input from CMOS image sensors with resolution up to 1.3M pixels. The image processor contains a JPEG and Motion JPEG encoder/decoder for handling still images or video. Audio is received by a microphone interface and converted by an internal ADC with digital AGC. The encoded video and audio are stored to an external non-volatile memory such as an SD card for video recording. The captured image or video can be displayed on an LCD by the integrated LCD controller and passed together with audio to a PC through a USB 2.0 interface supporting UVC and UAC device class definitions. The audio can be played back to headphones or speakers from the on-chip DAC.

The image/video captured from CMOS sensor is optimized by the image signal processing features of the AX3231 such as auto exposure, white balance, defect pixel detection and cancellation: configurable noise reduction, image sharpness enhancement, color correction, brightness, contrast, color saturation and hue.

AX3231 contains an internal hardware image acceleration engine which provides image manipulation functions like rotation, mirroring, virtual display, picture-in-picture with overlay, zoom in/out.

Rapid application development is supported by a complete development toolkit which includes a GCC compiler and a GDB debugger with on-line debugging through JTAG and USB.

The high integration and performance of this digital video SoC solution enables popular consumer products such as drive recorders, baby monitors, wireless cameras, surveillance cameras, web cameras, and digital video recorders.

MD80 720p 60FPS - JoyHonest
131104 - The camera producer sent me a 3.36 second sample video in outdoor light, taken with a class 4 SanDisk card.  This camera is still in development so a delivered cameras might be different.
Summary - The video is AVI, MJPG, 1280x720 at 60FPS and the missing frame rate of the sample video is about 8%.  It has an AVI data rate of about 5.5 MBps.  The audio is PCM 352.8Kbps, 22050Hz,16 bit.
Comment -  A data stream of 5.5 MBps is extremely high.  Some class 4 cards will not write that fast.  The producer needs to clearly specify what the minimum requirements are for quality video.

131027 - Joyhonest is producing an MD80 with 720p 60FPS video based on the 5MP OmniVision OV5640 image sensor .  Release data is TBD.

"The OV5640 delivers a complete 5-megapixel camera solution on a single chip".  This is the first micro camera that I know of that has 5 megasensels, 4:3,  2624 x 1956.  The width of the image array is used, and scaled down to 720p video.  It also does embedded JPEG (MJPEG) compression in hardware.

FEATURES:  5.0 mega pixels high resolution.  Support PC camera and chatting function.  Voice control function, more than 60db begin.  Support AVI video format.  It can carry out high definition image recording under low illumination.  Support Sound control video and Take video when charging.  Support 60 fps for 1280*720 video shoot and output.  Mobile U disk and Card Reader function.  Support MAX 32GB T-flash card.  Built-in Li rechargeable battery lasting for about 60 minutes.  Color: black.


  
130821 - MD-80 like the 808 #19
Roberto from Italy sent me this information about an MD-80 that is electronically like an 808 #19.

Corrupt AVI - The camera produces a corrupt AVI file.  It plays in some players.  It loads into VirtualDub but does not display.  Avidemux can be used to partially clean up the AVI file but not un-corrupt it.  The missing frame rate is about 33%.  A sample AVI file (10.1MB) is in the MD80 folder of the vault.

It installed in windows 7 64 bit downloading drivers from Microsoft.  Drivers are universal and made by Microsoft so I can't have any  information from them.

There is only one crystal but RTC works also when the camera is off. The SPI flash is a eight pin Winbond 25Q40BVSIP  1233. Strange, it seems a 4kbit (512 bytes) flash. It is a 4Mb (512K byte) SPI flash.

111113 - MD80 Schematic
A person in  Ukraine sent me this PDF (170K) schematic of the MD80.  It is probably similar to the 808 #3.  It might be useful to someone who is modifying the camera.  In the vault in the MD80 folder: MD80_3_2.4.Sch.pdf

http://adv-md80.at.ua/ is a Ukraine forum (Russian, so you might need Google Translate) about modifications to the firmware of the micro cameras (MD80, 808, ...) that use the Sunplus SPCA1527A and SPCA1528 processors.

OV7670_MN is the camera module 24 pin connector.
SPCA1527A is the processor.
K4S641632K is the 8 megabyte (64 megabit) SDRAM.  16 data lines and 12 address lines.
W25X80 is the 1 megabyte (8 megabit) serial (SPI) flash memory where the firmware is stored.

  MD80ExternalBatteryMod 
110928 - MD80 External Battery Mod
CAUTION - DO THIS MODIFICATION AT YOUR OWN RISK.  A LiPo battery can explode, cause a fire or cause personal injury if not used correctly.  A monitored bench test must be done,  The test must go through a full charge and discharge cycle to insure that the modification is safe.  Any replacement battery must have a protection circuit.

Sasha created this mod to an MD80 to replace the internal LiPo battery with a larger external LiPo.  Before the mod, the internal battery is connected to ground and +bat on the circuit board.

The internal battery was removed.  The 10K resistor was removed (see photo) and a wire was soldered from +bat on the circuit board to pin4 (ID pin) of the internal mini USB.

A mini USB cable was modified to support the external battery.  The type A (4 pin) connector was removed from the cable.  The external LiPo battery red positive lead is connected to pin 4 (unused ID pin) and the black negative battery lead is connected to pin 5 (ground) of the cable mini USB connector.

The camera is powered by the modified cable and external battery.  Whenever this cable is removed, the camera date time defaults and needs to be set again. To set the date time connect the modified cable then insert a flash card that has a date time file on it.  Power the camera off and on.

To connect the camera to a computer use a normal mini USB cable.  The camera will be powered from the power on the USB cable.

  110731MD80
110731 - MD80 Anonymousie Comments
Anonymousie in Russia reports the following about his MD80.
I have a MD80 clone (#3 camera), and I have a few things about it that I would like to share:  

- It has a mode (which stays on until you turn the camera off) where you can record while it's plugged into USB (computer, charger, battery pack)--just hold down the record button while powering the camera on (with either power button, or plugging USB in).  

- I happened to brick mine while trying to get the camera to upgrade its firmware from the microSD card (because I use Linux, and I don't know of any firmware upgrade tools for Linux...). The lights were off, all the buttons did nothing, and it was not detected by the computer anymore. I managed to get it detected again by pressing the reset button while shorting the 2 pins of the spi flash chip (the ones nearest the USB port). I then somehow got the ISP bootstrap (or whatever it is) loaded and running on the camera, but don't know what to do after that to reload the correct firmware. Time to look for a Windows computer :(  

Here's the webcam/programming mode dmesg output before the bricking:  

USB 1-7: new high speed USB device number 60 using ehci_hcd
Linux media interface: v0.10
Linux video capture interface: v2.00
gspca: v2.12.0 registered
gspca: probing 04fc:1528
spca1528: Omnivision 3.1M Sunplus CA1528
gspca: video0 created
usbcore: registered new interface driver spca1528  

And here's the dmesg output after the reset with my method:  

USB 5-1: new full speed USB device number 53 using uhci_hcd
Linux video capture interface: v2.00
gspca: v2.12.0 registered
gspca: probing 04fc:1528
spca1528: �A�p8U"��>����r�i��0�%R�^�Z�i��0�%R�^�Z�
gspca: video0 created
usbcore: registered new interface driver spca1528    

In Linux, the webcam driver is not needed to program the camera.  

By the way, the Russians have figured out a way to make this camera do loop recording as well as autostart and other neat features/hacks. They have also figured out a way to put the camera into programming mode via the usb port (the 5th pin that is normally unused on other devices).    


MD80TimestampRemoval  
110210 - MD80 Timestamp Removal and Firmware Swap
Bob (BobFlyman on YouTube) in Brixham Devon England has an MD80 camera. The electronics are almost identical to the 808 #3.  Using the 808 #3 methods, he removed the timestamp from the firmware. 

His comments:

I downloaded the 1528.bin.raw file from the MD80 and found it to be exactly same size (1696 kb's) as in the type #3 808. Plus 'verify' worked in ISP.  I took a gamble and tried the files for 808 date time stamp removal (in your 30 October 2010 post) on the MD80.  Success.  Date stamp removed. Process worked exactly as described in the videos linked.
 
Function now - Red and blue operation lights now work differently and it behave more like the 808.  The blue is on when powered up. Short press of 'record' makes a jpeg and long press, results in 3 blue light flashes and it's in record mode. One short press stops record mode. It no longer works sound activated mode.  The  'mode' switch no longer switches the camera to webcam mode. Red light has no function. The jpeg's have a blacked out area where the time stamp should be, as is the case with the 808.
 
I have yet to test all 5 of cameras to see how the frame rate is now, but short tests seem to indicate it's ok.

      
110526 - MD80 Firmware
Angelo from Italy contributed this MD80 firmware.  See the 808 #3 page for instructions about installing firmware.  Use at your own risk. 

The attachments are MD80 firmware, seems to be a #3 clone, extracted from my cam, one is the original and the other is NoTimeStamp, tested on my cam.

110418 - MD-80 Photos
Christian in Germany provided these MD-80 tear-down photos.

Here are some pictures of the Mini DV80 that I bought on ebay. Video files are saved as SUNP0001.AVI and a multi-language manual that also describes the sound triggering function can be found here: http://www.playdeluxe.de/bilder/Bedienungsanleitungen/minidv-md80_usermanual.pdf Although I don't know if it is sound or motion triggered as the manual on the driver CD (which I had to translate via Google translator into English) says it is a motion trigger while the above link that I found on the internet describes a sound trigger.


  
110315 - Buyer Report
110302 Jurgen from The Netherlands received an MD-80 camera today from: kkwfvp. $10.50. "Has blue/red led (no yellow) and records in MJPEG. Use it wit Optoma 4GB Class 4 microSD. Battery gets a bit warm.  I think it's (like) a 3. Motion isn't that good and it looks a bit telephoto."

2010 Sep 10 - MD-80 USB External NIMH battery Pack
Joao created a battery pack with four NIMH batteries that he connects to the MD-80 by the mini USB connector.  The battery pack can be used to charge the MD-80 battery.  The battery pack can also power the camera while taking a video (the 808 camera can't do that). 

Caution:  When fully charged an unloaded NIMH cell is about 1.43V.  So 4 cells could be as much as 5.72V which is above the USB 5.25V maximum.  Although this mod might work, I am not endorsing it.  Use it at your own risk.

I've got 3 MD80 cameras, bought on different occasions and from different sellers, and all can be set to record a video and be powered from and external source.

I've rigged an USB power source using a 4 AA battery holder, 4x AA 2100 mAh NiMh batteries, and a mini USB cable.
I've attached the construction photos (5 minutes, all in), so you can publish on your site, if you wish.
Mind you that a note should be included, stating that this will work with 1.2v rechargables ONLY, as USB specs state voltage should be between 4.75v and 5.25v. If AA 1.5v cells are meant to be used, a 1A diode, with 0.7v forward drop  should be used.

Used materials:  1x mini USB cable,  1x 4 AA battery holder,  4x AA batteries,  shrink tube

Tools needed:  Soldering iron,  Heat gun (or lighter)

2010 Sep 08 - MD-80 PIC Micro Mod - Optical Sensor Starts and Stops Recording
Anix in Russia sent me this MD-80 PIC12F629 mod.  It uses an optical sensor to start recording in the light, and stop recording in the dark.  Opto couplers are used to control the camera buttons.

Shematic circuit - photorelay.jpg

My MD-80 DVR can start record 2 minute video at sound detection. If background noises in this place, many fault detections appears.
For surveillance in seldom visited place, for instance storehouse I make the small device, which start the camera recording, when the light-on and switches off if dark. The Photorelay is assembled on PIC12F629 and several components. Also I have connected external more powerful Li-Pol battery for feeding the camera and photorelay. PIC output are connected to button PWR and REC through optocouplers TLP120. Optocouplers has miniflat formfactor and placed inside DVR case with smd resistor 200 Ohm. Internal battery was disconnected and removed. For correct connection optocouplers to buttons, measure the polarity of the voltage on them. 4 wires with minijack, connect DVR with photorelay and external battery (+U, GND, PWR, REC). Also You can use these wires for remote control of DVR, just connect few at a time PWR or REC wire to +U wire, for pushing corresponding button. DVR buttons also work.
Photorezistor CDST18 or CDST05 used as light detector. You can use any photoresistor with dark resistance 100kOhm and light resistance 5 kOhm. Also You can use Phototransistor or Photodiod, but I don't recommend, since its Infrared sensitive devices, and do not working if You use florescent lamps. Use it only if sunlight or bulb lamp used for illumination.
This detector very sensitive, to reduce his sensitivity, connect between base of the transistor and GND variable resistor about 1 Mohm and adjust sensitivity level.
Before power-up of photorelay, make sure that DVR is switching-off.
The Algorithm of the work:
- At power-up with switch S1, microcontroller push button REC and waits 32 seconds. (This is made to in the event of hovering the controller, he was able when initializing to stop recording and DVR itself was switched off. If DVR is switched-off this does not render on it influences but gives You possibility to come out of room and switch off light).
- Microcontroller start light detection procedure. If light-on, microcontroller push PWR button and after 1,7 sec push REC button. This delay need for initialization DVR after power-on.
- If light-off, microcontroller push REC button and after 3,5 sec push PWR button. This delay need for resume recording and SD card writing processes.
Photorelay current consumption in "light" mode around 1ma, in "dark" mode around 0.25ma, then buttons pushed 15ma.

MD-80 Notes
2010 March 19 -  Notes from Johan
The camera works a little different from the 808 becase it has 3 buttons: 1 power, 2 mode and 3 shutter/start

1 power is obvious:) a blue led is visible, if you have tag.txt in themain root a red 0ne blinks fast for a second(it blinks like the led on a reading/ wriitng hard drive)
2 mode selects video via shutter or video via sound treshold
3 the shutter button starts and stops the recording a red led is on while recording
 
After you stop a video recording the red led blinks again like a hard drive led while writing.
 
Photo mode seems not to be possible
 
The camera seems similar to a type #3.
Time is like a #3 camera resolution is 740x480.
It has  a  webcam mode that is activated via the mode button when linked with a usb port.
 
Also the TAG.text file that is on the CD
The file doesnt work until you rename it tag.text  the chinese had capslock on i think :).
There is an = after the timemark, maybe something to do with remove??
I tried N after the = but that didn't work.

The chips have these markings
 
The big one beneath the camera reads: SIEMENS, HYB39S641608T-8, USA B, W22318, 9938
 
The tiny one in the bottom reads: cFEON, F16-100HIP, E32749G, F941HSD
 
The big one on the other side is a: mM SPCA1527HL091, W01F967 1, 0949
 
This camera comes with some extra's as described in the manual.  The spca driver is included in the cd-rom.
 
My personal opinion is that the build quality is better, the camera feels solid and not as flimsy as the keychain fob.
The weight is a little heavier at 18 grams (without the camera stand that is an extra 10 grams)

MD-80 TIPS
2010 Apr 30 - Mick's tip about external power through the mini USB connector
I am using one of the cheap MD-80 clones from JOYMYFUN and have found a way to plug in and run an external battery supply. I have tried a single AA battery mobile phone charger and a 2 battery AA phone charger. I can even record while powering from USB and AC.
The trick to it is so simple.
Firstly, with the camera powered off, press and hold the record button in.
Next, insert the power supply  into the mini USB port in the camera.
Keep holding the record button in while the blue L.E.D comes on and  the red L.E.D. flashes a bit.
When the blue L.E.D. in stationary and red L.E.D. is off, you are ready to go.
 
So simple and this has revolutionized the way I use this camera now.
