Walkera DV04 the 27$ HD video recording + FPV camera in 13 gramms only

I did not find much info about this camera, and as you can see from the price, is looking excellent for FPV, and recording: http://www.banggood.com/Wholesale-Wa...r-p-66221.html

It is state to be 1280x720p microSD recording , encoding in MJPEG (that has some pro and cons, mainly it produce monster big video files, and as well it require a fast SD card)

It should be a 576i composite output ...

Only 13 gram .... perfect for small application

Works straight from 5V .. so perfect for be connected to normal RC gears

PS: Found some specs:

I found some specs for th DV04 that say: , .DV04 Specification:
‧Pixel: 200 Mega pixel (this number is wrong, but is repeated very often as a spec of DV04 .. probably is just 2.00Mega Pixel
‧Definition: 420TVL
‧Storage card: Micro SD
‧Working voltage: 5V - 8V (warning, somebody on the net state it destroy his DV04 using 7.8v ... so better stay with 5v or 5.5v max)
‧Resolution ratio: 1280*720
‧Color: Color
‧Working temperature: -40°C - +85°C
‧System: PAL / NTSC (I can't get anywhere how can be this switched, or if there are two type of this DV04 ... somebody reported 576i , this is PAL not NTSC)
‧White balance: Auto
‧Weight: 14g
‧Dimension: 44*36*10mm





EDIT: Now this is sold also by HobbyKing for a decent price: http://www.hobbyking.com/hobbyking/s...elicopter.html

So with this cable is possible to have:

Get a clean 4 cable for video ... +5v , GND , Video out , Audio out

MJPEG? I'll pass on this one. Nothing else about the camera matters when it uses such a terrible video format.

I know, MJPEG sucks ... mainly it make monster big video, and indicate a poor processing power ... still ... each single frame is independent and almost in photo quality mode

If I remember right, gopro also use MJPEG , at least old version of gopro

I have a #11 keycam ... I know, with #18 I can get video out too ... but .. this camera is lighter due to no battery ... it has direct 5v power, and direct connector ... on top it has a better housing for mount more easily, plus the camera is looking orientable ...

For 27$ is a no brainer for me

I order it from banggood, and I hope it can come soon, once I get I can make a comparison to my old but still solid #11 808 keycam

comparison to 808 #16V2

I wonder what is the video quality difference between this Walkera and Key Chain 808 #16V2. Do you know what FOV does DV04 have? And there is one more camera, that Walkera started to produce-smaller and without AV out.

Once I will get my DV04, I will compare the video quality with my #11, I don't have #16 or #18 to compare ... but based on what I can see on youtube, quality is going to be a bit worst then these, even then #11 ... still ... it cost less and weight less ... and is better designed for RC with movable inclination ....

Gotta wait still 2 or 3 weeks ... since I look on backorder

Here is a link to a Walkera camera that I came across. The price is much lower than anyone else that I have seen so I don't know if there is a catch.

I did not update here ... since there was not much to update.

I got few days ago the DV04 ... after a HUGE delay ... and a fake statement from BangGood about when it was shipped.

And I got a defected item ...


Hoping to get a refund from PayPal (that I did not got, since PayPal asked me to send back the DV04 over a traced shipment, that would cost almost as the 27$ paid, and plus I need to waste time on packing and go to a postal service with proper tracking (only DHL around me)) ... hoping to get a refund I did order a second DV04 ... and again ... shipped on the BangGood web site shown after 2 days from the order ... but ... per China Post (this time they used China Post, the other came from HongKong post) ... show that my parcel has been received few days ago ... almost 2 weeks after per BangGood it was shipped

I was lucky with my previous 6 order from bangGood ... but... due to this ... BangGood even if offer sometime very competitive price ... it is as good as dead for me ...

BE AWARE !!!

Sorry to hear of your difficulties. Has anyone bought this camera elsewhere than Bangood?

I see that now it is available for decent price also from eBay (29.99$)
http://www.ebay.com/itm/WALKERA-DV04...-/171040426136



Anyhow ... judging from the feedback on this thread, this camera it is not very popular ... I guess FPV people and camera people are looking for more advanced and expensive gears ... even if ... #16 + #11 , #18 and #3 are very very popular here in RCgroups

Finally I got a working DV04 cam.

Here are a couple of video, one from a 600mm EPP Wing (Bonsai) .. less then 180g bird .. and one on my new TriCopter

On a tricopter the video is way more stable then compared to #18 ... but ... quality is a bit lower then #18 ... but mainly the AoV ... it is very narrow ... it is like a 4x zoom compared to #18 that it is already not a wide angle cam.

Anyhow ... here are the video for reference ... later I may add some further comment over this cam:

HobbyKing X900 Tricopter with KK2.0 and Walkera DV04 cam (0 min 0 sec)


HobbyKing Bonsai, 600mm EPP wing, onboard video from DV04 (0 min 0 sec)
