Mate808
808 Mates Micro Camera Mate808 with 120 Degree Lens
The Mate808 is one version of the 808 car keys micro camera.

160411 - What's new - This 808 claims to be 1080p, 30 FPS, and is the same 20 gram weight and size (32 x 52 x 15 mm) of the original 808 camera released in 2009.  Uses a micro USB connector, not the mini USB, not the 8-pin USB. Available with a 70 or 120 degree lens.

160419 The Mate808 is a high definition 1600 x 1200 video camera up-scaled to 1920x1080. It is small in size, very light weight and low cost. The low power design records for a long time and the camera does not get hot. The video has some some JPG artifacts and the video files are very large.

160411 The producer of the 808 #11, #18 and #26 notified me that the Mate808 is being sold on eBay and Amazon.  Produced by Hetai Digital Technology Co.,Ltd, www.Htinter.com, eBay: hxelepro360 and eletech086, MateCam, Matecam Tech.co.,Ltd, www.MateCamera.com.

160417 - Received two cameras.                  
160411 - I have ordered the camera and will review it when it is received.  Delivered from China.

160418 - Mate808 Metrics, 70 and 120 cameras
160418 I received two Mate808 cameras, one with 70 lens and one with 120 lens.

WEIGHT
Weight of camera without flash card. 
70 - 16.31g
120 - 17.06g
Weight of my Samsung SDHC 32GB is 0.24g.
Weight of my 808 #16 V1 camera with D lens, no lens cap, is 18.6g.

SIZE & CASE
120 camera - Dimensions empirical 56.5 x 32.9 x 15.2 mm.  The lens has an OD of 10.0 mm.  A lens cap is not provided but one should be used.  The 808 #16 D lens OD is 10 mm and the lens cap fits the Mates808 lens. 
70 camera - Dimensions empirical 56.2 x 32.9 x 15.2 mm.
The plastic case has approximately the shape of the original 808 from 2009.  The bottom surface is rounded so it does not sit flat like the 808 #16.  The case bottom is embossed with "#18", probably because the producer of the 808 #18 makes the Mate808.


INITIAL USB CHARGE CURRENT
When received, I started charging the cameras.  The 120 camera took longer to charge, so the initial charge might have been lower.  Initial charge current:
70 - 175 mA
120 - 325 mA
