View Full Version : For Sale: Dog Cam Bullet Camera & JXD Recorder
Up for sale as I don't want to take it with me! I ordered it for the Lydden track day we did in October but the video recorder never arrived in time.
I got the recorder from China, it's the:
JXD 638 mp3/mp4 player
The Dog Cam came from Dog Cam sports:
DogCam Pro 520 bullet camera package
1 x DogCam Pro 520 Camera
1 x 8 x AA Battery Holder
1 x Fixed Mount
1 x Stereo mic splitter
1 x 12v A/V Microphone
1 x DogCam Suction mount
At the time the vid recorder cost £68 & the dog cam £145. This wasn't including p&p.
I have used them twice - once for a 10 min ride around the block to make sure they worked & the second time for the 30 min ride around London.
£130 to an orger incl. Recorded P&P.

You got any clips of it?
Are you interested in selling the bullet cam by itself? Price?
If so, first dibs :D
Just so as I don't put anyone else off, I'm looking at a multi-cam rig, I already have the JXD, although not the exact one Kinvig is selling.
I regularly use mine as an MP3 player whilst on the bike.

Arrived today. Cool toy :-D
What sort of recording times can you get from it?
I think the next purchases/bodgings will be a couple of decent sized SD cards, and a regulated 12v and 5v power supply.
Any ideas?
I just picked up a 4 GB sdhc card from curry,s for ?27 and thought id done well till i saw this www.7dayshop.com (http://www.7dayshop.com) check out the prices for memory, Ive used them in the past and they were very good, fast to deliver and good value

There was a thread last week about *really* cheap sd cards - you'll want one with quick writing capabilities (san disk ultra II etc)
I never got around to using the dog cam properly so I have no idea about setting up to the bike battery. As for recording times - there were probably loads of settings on the jxd that I never got round to figuring out - I was recording something silly like 10 meg a minute. Good size & quality at that rate though....

be careful - I think that the max memory card size for the JXD unit was 2 gig

My little ATC2000 does about 105 minutes at 640x480 30fps on a 2gb SD card, should give a rough idea I'd guess.
Cheers Mark.

Mine (JXD921) will happily play with 4GB.
As for recording formats, can't remember, but the default on the 921 is OK. Approx 3mb/min. On a 4Gb card, that works out at 22hours total. I can't speak for other versions of the JXD though.
www.dogcamsport.co.uk (could be .com) do some good regulators, a little expensive, but you want better quality otherwise you'll get the images on the cam messed up by interference.

hmmm....I'll check when I get home. Not sure what that is then.
It came from China so it could be some chinese format stuff.

This is doing way more than that, more like 9mb/min, thats at 320x240 in avi, more than that in asf. Will mess about with it a bit more when my nimo's are charged.

It could be that it takes nes games & they included those as an extra, maybe.

Make sure you fit a fixed voltage regulator ... the camera might not like 14odd volts from the bike! ;)

20-02-08, 07:38 PM
Indeed, read about a page back... :-P
Btw. Dogcam's website doesn't mention what end fitting is on that 5v regulator they sell, anyone got any idea?
I'm not sure whether to get dogcams regulator, or just a regulator IC and a big lump of a capacitor to smooth it out, that way could just mount them to a plate for heatsink and pot it in epoxy, for about £4 rather than £25

dude ... fixed voltage regulators, no piddling about, no risk - 77p - Job done ;)

I have a 9v and a 5v, but don't use the 5v (on JXD) as it seems to cause interference.
But they have internal battery, so I tend to let the JXD run on its own steam and the camera on the bike 9v regulated.
I then put the JXD on charge between sessions ;)

Having a bit of bother with it, can't seem to get a smooth vid no matter what settings I play with on it.
I know a good signals getting to the recorder, as the LCD shows a good, smooth picture, but when you replay it, its got blurred squares any time there's a lot of movement.
The only settings I can find are asf/avi and 2 resolution settings.

Dogcam I got was 12V regulated - runs from 8xAA batteries also - an AA battery being 1.5V - so x8 and its 12V
Maybe your cam is a bit different tho

Kinvigs just said he got excellent results using an SD card instead of internal memory which is only 25 minutes at low res avi.
Both, same problem any time there was movement, on the road and as I walked through the garage.
yorkie_chris
03-03-08, 03:26 PM
Same problem occured with any movement at all, as I walked through the garage and on the road.
Kinvigs said he got good quality using a sandisk SD card rather than the internal memory. Sounds like a plan, as the ability to swap SD cards on longer rideouts to film the whole thing will be good.
Running it on 8x 2200mAh 1.2V NiMH cells, technically same setup as dogcam offer on the website @ 9.6v. Confident its not a power issue or a bike electrics interference issue, as the problem is affecting only the recording. LCD is clear and "true" at all times.
Edit: as for interference I'm going to get a decent sized smoothing capacitor on the 12v and 5v supplies, anyone know where to find waterproof connectors? The wiring loom coming out of my head is starting to take the Pi$$, what with mp3, mic, and cam. Needs neatening up a little.

If you look at the spec (http://www.rfconcepts.co.uk/21cph.pdf), they have a working voltage range ... 8-15v in that case.
Yours might be a bit more fickle, but the one I have got is fine on a strong 9v. 8)

It's the same 8 AA batteries one.
I think it's just the JXD trying to process the image & record it to its internal disk at the same time, so an Ultra II SD card will cure it.

Seems to work down to about 8.5 when the NiMH are getting quite low.

Try recording off the telly!! (i.e. take the input from TV/DVD/PC, not the cam) ... if it is still plops then the JXD is goosed, if it is ok, then the cam is goosed ;)
Try

You can see a good image on the LCD screen of the JXD at all times, it's only playing back a previous recording that causes problems.
However I'll give it a go later for the sake of it.

It makes no difference internal or SD on mine ... so it'd still be a problem ... (but if it works with SD, then it is not a show stopper ;)).
you need to use a diff external source to see if it is the JXD or the CAM.
Oh and finally you have built-in camera, try recording using that (don't plug bullet cam in) and the play it back .....

External screen is the uncompressed version - so make me think the cam is fine.
Does sound like compression is the issue.
Bear in mind that the movement you are putting it through, may actually be more extreme than when on the bike - so where a quick pan across your living room might break up, normal riding may be different

I actually think the problem could be that the 520 line cam has too much data for the JXD ... ok when sat still, but wave it about and 'computer says no' ... perhaps?!!?? Dunno, just trying to think a bit 'outside the box' ...
Taking data from TV should narrow this down ...

It arrived too late to take to the Lydden track day so I tested it going around the block before putting it to one side.

If you mean on the JXD itself, the hole is hidden under a rubber flap :p
If you mean to buy one that you can use to plug in (given the questions about regulators etc), pop down to Maplin. They have multi-packs of DC jack connections, the one with a yellow circle on the tip fits my JXD921.
yorkie_chris
04-03-08, 05:02 PM
Standard charger uses a choke, and Im presuming an internal smoothing cap, this could be why blue had inference if you were just using a regulator?
Edit: No rubber flap on the 638 thing that I've got. Just a connection fora really tiny yellow tip barrel jack.
Ideally would be a cable with a moulded right angle end on the input side and a grommet on the other end so I can fit it nicely into the project box. But what's the chances of that :-P

I actually think that its coz the input to the 5v regulator was too high ;) If you read the spec the 5v reg can only handle a max of 12v(think it was 12) and as we all know when running bike is at 13-14v ;)
Either that or it was between the earth of the cable and earth of the casing ..

Ah right I'm going to run the 5v reg off the regulated 12v with capacitor and choke.

Ah right I'm going to run the 5v reg off the regulated 12v with capacitor and choke.
I ran them both separtaly off the battery. I am thinking of running the 5v one of its own parent 9v one and see if this resolves the interference problem ...
When the bike is not running it works fine, its only when bike is runnig I get a problem ...
