Mate808, 1080p, 20 gram class, 808 Micro Camera


MANDATORY READING: POSTS 1,2,3,4.

The purpose of this thread is to discuss Aerial Photography applications of the Mate808 camera. The Mate808 is off-topic at the 808 #16 thread, but it has been discussed there since it might be of interest to #16 owners. Bring the discussion here. I use this format for dates: YYMMDD.

LATEST NEWS
160929 New firmware JH_7556_0363F554.bin.
160707 The MATE808 producer says the Mate808 supports UHS-1 type micro SD cards.
160622 New firmware JH_7556_036410C9.bin.
160506 New firmware JH_7556_035C31A0.bin. Fixes CORRUPTED LAST RECORDED FILE.
160426 Concern: CORRUPTED LAST RECORDED FILE. Symptom: When the Mate808 records video files to fill the flash card, the last file written is corrupt. The maximum size of each file is 2GB. The last file does not play at all, or it plays in some players but without random access. The producer has been notified of this problem.

OVERVIEW
The Mate808 is a high definition video camera (sensor 1600x1200) that re-scales and writes a 1920x1080 AVI MJPG video file. It is small in size, very light weight (20 gram class) and low cost. The low power design means it records for a long time on a battery charge, and the camera does not get hot. The video has some some JPG artifacts and the video files are very large. The video is not H.264.

CONFIGURATIONS
Case, 70 degree lens.
Case, 120 degree lens.
No case, 70 degree lens, 3 cm extension camera-flat-cable.
No case, 120 degree lens, 3 cm extension camera-flat-cable.
No case, 120 degree lens, 15 cm extension camera-flat-cable.

The 120 degree lens in 1080p video mode measures 110 degrees.

Note that the camera producer says that the Mate808 video quality has been designed to be better than the 20 gram class 808 #18 but less than the 40 gram class 808 #26.

PROS & CONS

PRO
High resolution - The camera uses a high resolution 1600 x 1200 image sensor.
No aspect ratio distortion - Round objects appear in the recorded video as round objects.
Light weight - The Mate808 is amazingly light and small for a 1080p camera. It weighs about 17 grams, about 2 grams lighter than an 808 #16. With the case and battery removed, it weighs about 6 grams, hence usable with light Radio Control devices.
Low cost - The low power design results in a smaller battery, lighter weight and lower price.
Long record time - Empirically, 72 to 75 minutes per full charge. The camera has a power-efficient image sensor and video codec (MJPG). This results in lower power consumption, small battery, long record time, and light weight.
Does not run hot - The camera does not get very hot while recording. Some micro cameras like the Mobius and 808 #26 get very hot.
No missing frames - With the 30 FPS firmware, the 1080p file seems to have 30 real FPS and no missing frames.
Good video quality - See sample video and you decide. The video frame quality seems "good", with good detail and reasonably real color.
Good Audio - PCM, 32000 sample per second, 512 Kbps, audio quality seems good, with little to no camera-induced background noise.
USB is standard - The USB is a standard micro USB port.
Has webcam video - Webcam mode works, and works with with Skype, video only, no audio.
Has video out - With the Video out cable connected, the camera output NTSC 480i composite video and simultaneously records at (720p or 1080p) to the flash card. No audio at the cable. Four output modes: video, photo, motion detect video, playback.
Many cables - Comes with 4 cables: Micro USB, FPV, video out and OTG cable. The OTG cable (micro USB male to USB A female) and the micro USB cable together allow you to charge the Mate808 from a cell phone. The cell phone acts as a power source. Only some cell phones support OTG.
Some class 6 cards work - No problems with my Samsung class 6 32GB SDHC FAT32 card formatted by Windows 10, Crystal Disk Mark write benchmark about 12 MBPS.
Lens selection - The camera is sold with a 70 degree or 120 degree lens. The 120 degree lens OD is 10mm, the same as the 808 #16 D lens. Both can use the same lens cap.
Photo mode - in 720p mode 1280x720, in 1080p mode 1920x1080.
Micro SD flash card - FAT32 only. Support for SD, SDHC and SDHC 64GB.
In-Camera-Formatting - In standby mode, holding the shutter button for 10 seconds will format the SD card.
UHS-1 SD cards - The MATE808 producer says the Mate808 supports UHS-1 type micro SD cards and protocol.
1080p or 720p - The user can configure the camera to produce 1080p or 720p video files.
Configuration file - The TAG.TXT file in the card root is created by the firmware. Then the user can edit it to configure the camera. It configures: stampMode, poweron_record, auto_poweroff, recording_indicator, rotate photos, loop recording and video size.

CON
Up-scaled video resolution - The image chip is a 1600x1200 GalaxyCore GC2145. The recorded video file is 1920x1080. So, there is cropping and up-scaling. My analysis: For video, the sensor image 1600x1200 is cropped to 1600x900. Then it is up-scaled to 1920x1080. Objects in the video are not aspect-ratio distorted.
MJPG file size efficiency is low - The 1080p video files are very large, about 400 MB per minute. Video codec is MJPG, not H.264, so the compression efficiency is low and the file size is large. But MJPG offers more power efficiency and less hardware cost, so the camera can be smaller, lighter and cheaper. The AVI file consists of a series of video frame chunks stored as JPG images, and the audio is stored as chunks of PCM data. The video player reconstructs all this interleaved information.
MJPG atrifacts - The video MJPG codec introduces JPG-type compression artifacts into the video. But, you might not even notice them.
Enormous video file - MJPG and high resolution means the AVI video files are enormous. Flash cards are cheap, right? Expect about 6.6 MBps, 400 megabytes per minute, 80 minutes on a 32 GB flash card. Re-encoding AVI to MP4 (H264 or H265) using Handbrake or equivalent can reduce the file size by 60% or more (H264 multiply by 0.4, H265 multiply by 0.32).
Dim LED - LED is small and somewhat difficult to see through a small hole in the case in outdoor light.
Webcam no audio - Webcam mode works but there is no audio driver.
No Lens cover - 120 degree lens (10mm OD) does not come with a lens cover, but needs one. The 808 #16 lens cover works.
Mounting - No camera mounting bracket. Velcro is provided.
Case rocks - Case bottom is a rounded surface, so the camera rocks back & forth on a flat surface. The 808 #16 case is similar but with a flat bottom.
Photo size - Photo mode always takes 1280x720 photos, it never takes 1920x1080 photos. The producer says this will be corrected in a future firmware release.
Requires fast flash card - The producer tested this camera with class 10 and faster flash cards. Use a class 10 or faster card, or benchmark your flash card to verify it writes 7 MBps or faster.
No 60 FPS - 30 FPS only.

==========

Camera Producer - Matecam Tech. co., Ltd. Brand is Matecam. Camera name is Mate808. The producers website (under construction) is www.MateCamera.com. The parent company is Hetai Digital Technology Co.,Ltd, www.Htinter.com.

2016 April 11 - The producer of the Mate808 camera notified me that the camera is available and being sold on eBay and Amazon. As far as I know, it is the first 808, 20 gram class, 1080p camera. The light weight makes it suitable for use on very light weight RC devices, for example, where a Mobius Action Camera might be too heavy. The producer also made the 808 #11, #18 and #26.

The producer gave me a Mate808 120 degree and 70 degree camera to review. I have an non-commercial 808 review site at www.chucklohr.com/808. My Mate808 page is at www.chucklohr.com/808/Mate808.

I don't plan to be the "moderator" of this thread and don't want that career.

INTERNAL INFORMATION & INTERNAL IMAGES

Case
The case has "#18" text molded into the bottom. The Mate808 and the 808 #18 have the same producer and use the same case. Newer Mate808 cameras have a sticker over the bottom to hide the #18 text.
PCB
The button side of the PCB seems to be glued to the case, making dis-assembly difficult or impossible.
Battery
Lipo with protection circuit, 250 mAh, cable and connector, 5.4 gram, 502030 (5.0x20x30 mm).
120 Degree Lens
Camera assembly is socketed, not soldered to the PCB. Camera assembly has glue on the lens tube threads, probably factory focused, and not refocus-able. Camera assembly is held in place on the PCB with hot melt glue. The OD of the lens is 10.0 mm. The front of the lens seems to be a flat glass surface, flush with the plastic OD. Camera does not come with a lens cap, but the lens cap for the 808 #16 fits.
70 Degree Lens
This lens is totally internal and peeks through a 2.5 mm case hole.
Image Sensor Information
GalaxyCore GC2145 - 1/5", 1.75 um pixel, Very low active power 180 mW. 1600 x 1200. GalaxyCore Slide Show.
SOC Information
Labeled 40 MP49837.00 1552. Probably a fab number.
Other IC Information
12.000 oscillator flat can. Black part might be a resonator.
Firmware Flash Chip
The binary firmware file JH_7556_03543459.bin file is 514340 bytes. All the text of the TAG.txt file is in the firmware file. The flash chip for firmware is probably 512K or 1024K bytes.
RAM Chip
TBD
Microphone
Electret. The case hole for audio to get to the microphone is very very small. Maybe too small.

producers documentation & firmware

To install firmware:

Summary: Copy files on the flash card to some other storage. Save the tag.txt file if you want to re-use it. Reformat the flash card. Copy the firmware bin file to the flash card root. With no USB connected turn the camera from off to on. The camera LED will flash for a few seconds. The firmware has been installed. Delete the bin file from the flash card root. The tag.txt file is default so edit it as needed.

Updated 15 May 2016 - Part of the procedure requires deleting the firmware BIN file while the card is not in the camera.
1. Save what you want from the flash card. Reformat the card FAT32. Copy the firmware BIN file to the card root. Make the camera off, no USB connection and the card in the camera. Turn the camera on, then the LED will fast blink for about 8 seconds. The new firmware has been installed.
2. Turn the camera off. Remove the card. Next, the BIN file needs to be deleted. Insert the card into a USB card reader, insert the reader into a computer and delete the BIN file. The card root will have: PHOTO folder, VIDEO folder, and a new tag.txt file. Edit the tag.txt file as desired. Insert the card into the camera.

Firmware releases. The firmware file extension is ".bin".
JH_7556_03543815 - original firmware 23 good FPS, 7 missing FPS.
JH_7556_03543459 - 30 good FPS, no missing frames.
JH_7556_035C3182 - Photo is 720 in 720 mode, 1080 in 1080 mode. Support for SDXC 64GB FAT32. Camera can format flash card.
JH_7556_035C31A0 - Fixes: last recorded file on a full SD card is corrupt.
JH_7556_036410C9 - In motion detect mode, no-motion-timeout changed from 10 to 120 seconds. Also improved the color balance issue.
JH_7556_0363F554 - Camera producer says: One customer complain that the video and audio can't be synchronous.

OPERATING PROCEDURE

IN-CAMERA-FORMATTING - CAUTION: In-camera-formatting will delete all video and photos on the flash card.
To format the flash card, in standby mode, press and hold the shutter button for 10 seconds. This does a quick format.

Button Timing
If (the camera is off and the power button is pressed for at least 1.5 second) then the camera turns on.
If (the camera is on and not recording and the power button is pressed for at least 3.0 seconds) then the camera turns off.

Switching Modes
The camera has three modes: video, photo and motion detect video.
The camera powers-up in video mode and the LED is ON.
Then, press the power button once to go to photo mode.
Then, press the power button once to go to motion detect video mode. Video starts to be recorded.
Then, press the power button to go back to video mode.

Motion detect video mode - Motion is based on optical change, not acceleration change. Motion sensitivity is not configurable.
o While recording in motion detect video mode, if there is no video motion detected for 10 seconds (in firmware JH_7556_036410C9.bin this is increased to 120 seconds), then the video file is closed and the camera stops recording and waits for motion.
o If there is motion, then a new video file is created and opened and motion detect video recording starts.

LED
o While recording in video mode the LED flashes at 1 flash per second.
o While recording in motion detect video mode the LED flashes 2 flash per second.
o While in photo mode, when the shutter button is pressed, the LED flashes once.

Exceptions
If the camera powers on and there is no flash card, a bad flash card or an un-formatted flash card, then the LED will flash 5 times and the camera powers off.


Q & A

Q. Where can the Mate808 be bought.
A. Search the internet for "Mate808" or "Matecam 808". Sold on eBay and Amazon.

Q. Can the 70 and 120 degree lenses be interchanged on the same camera?
A. The producer says: Yes,the lens is plug-able. we have the Lens F/ON=2.0 70& wide 120. (I think the producer means the lens F number is 2.0). People can change the lens by himself. But sorry, this is not available for #16 camera.

Q. Can you confirm that the image sensor is really 1080p? What image sensor is being used?
A. The producer says: Yes, this is the really 1080p image sensor, GC2145.
A. The sensor is 1600 x 1200. So, the SOC must be re-scaling to 1080p (1920 x 1080).

Q. Photo resolution is 1280 x 720. Can the photo be larger?
A. The producer says: Sorry for this not incomplete function, the BUG can be improved by the FW, we will send the FW to you later.

Q. What is the video quality of the Mate808 compared to the 808 #18 and 808 #26?
A. The producer says: The video quality is better than #18 camera, but inferior to #26 camera. as this is a cheap 1080p camera. But this Mate808 camera, with minimal work consumption (minimizing processing reduces battery drain), and won't have such hot issue (the 808 #26 gets very hot). Low power consumption, it can record long time when full charged.

Q. Can a SD, SDHC and SDXC card be used?
A: The producer says: SD, SDHC, SDXC, all can be used.
A. Someone needs to verify if SDXC cards with 32GB, 64GB, etc. can be used.

Q. What is the micro SD card requirement for the buyer? What is the minimum speed?
A. The producer says: It would be class 6 or better.

Q. What is the recording time on one full battery charge?
A. The video data rate and recording time is highly variable, but is typically about 450 megabytes per minute.
The recording time will be shorter if the video image is complex or the flash card is small. The camera uses the MJPG video CODEC, so when the video image is more complex, is more random or has more noise, the data stream is larger and the recording time is shorter.
RECORDING TIME TESTS - Each test starts with an empty 32 GB flash card. Video is recorded until the battery is exhausted. If the card becomes full during testing, the camera shuts down, I delete the files and testing continues. The camera writes many AVI files. The firmware limits each file to less than 2 GB, which is about 4 to 5 minutes.
Test0: 99 minutes. Stationary camera, black image (lens cap on), 120 degree camera, 1080p. 7.55E9 bytes, 76.3E6 bytes per minute (not typical).
Test1: 75 minutes. Stationary camera, daylight street scene with little activity, 120 degree camera, 1080p. 36.3E9 bytes, 484E6 bytes per minute.
Test2: 74 minutes. Battery still had charge. Camera Velcro under cap visor, daylight, while driving car, 1080p, 20.4E9 bytes, 276E6 bytes per minute.
Test3: 72 minutes. Filled the card. Camera Velcro under cap visor, daylight, while walking, 1080p. 30.1E9 bytes, 418E6 bytes per minute.

Mate808 Sample Video, 120 degree lens, 1080p, New 30 FPS Firmware


Here is a sample video file. Mate808, 120 degree lens, 1080p with the new 30 FPS firmware JH_7556_03543459.bin that seems to have no missing frames. The original file is 36.6 seconds long and 240812032 bytes.

Note that YouTube re-encodes the video so there is some quality loss.

Thank you!

I played the video and it is impressive for $28! It is clearer on the Vimeo site than by clicking the view above. Click on Vimeo, lower right corner to get there. I tried download of the original, but it wouldn't allow that. Instead it streamed live from the original 228mb source, in which the background is definitely clearer.

That looks pretty good for such a tiny camera. Is the #16 GUI useable on this one?

The download worked perfectly for me, using firefox, but you have to add the file extension, i.e. rename the downloaded file to 517345394.avi.

Obviously not There is no USB communication.
In the text file you can set 5 parameters:
  • Date and time.
  • Date/time stamp - on or off.
  • Recording indicator - on or off.
  • Power On Button Press - fast (1 sec) or slow (3 secs.).
  • *Rotate Photos 180 - yes or no.
*Rotate Photos likely means Rotate Video and Photos?

I don't have the camera but it would be interesting to see the manual and know where one can download the firmware files. I'm sure Chuck will add this info to one of his first posts when he has the time.

I would like to see a video comparison between Mate808 and 808 #16V3 D-lens. Might be interesting.

"video quality has been designed" - does this mean the video quality can be changed higher and lower? I have a class 10 card and would be happy with higher video quality - however, the codec that this camera uses is not efficient, resulting in large file sizes.

I wonder if the developer can make a H.264 firmware with the ability to choose quality?

I think H.264 encoding is usually done with special hardware on chip, and that is probably not in the Mate808.

There is a design trade-off.

H.264 encoding is very processor intensive and that translates to lots of power, heat, large battery and weight. If you have used a 1080p H.264 small camera like the Mobius or the 808 #26 you know the camera gets too hot to hold, and they weigh double the Mate808.

MJPG is as not as processor intensive. The Mate808 is technically amazing. 17 grams and 1080p, small case, small battery, low power chips, low power MJPG video encoding and HUGE file size. Today flash cards are cheap.

Also, if the excellent 808 #16 H.264 720p was upgraded to 1080p, all other things being equal, it would probably get too hot and the battery run time would be terrible.
