Bullet cam question ver 2.0

[Primaris]

Hello all,

Can I use this bullet cam with the Neuros MPEG4 Recorder 2? http://tinyurl.com/hpxnz Will I be able to record sound? 

How would the quality compare to this in car footage? http://tinyurl.com/jsaz8

Lastly power?  How would I be able to power the device in car?

Thank you.

If the bullet cam has composite video out and left or right audio out, then you should be able to record the video and audio signal.  About using the device in a car, using anything other than the supplied power source will void your Neuros warranty.  The recorder 2 is solely designed to be used indoors on a desktop to record video.  We cannot guarantee the recording quality if the device is taken out of the recommended settings.

Thank you for the quick reply.  However, I am new to video recording so I included the link above to the bullet camera so I could get a yes or no answer. 

How about the quality?  Any chance a current user of the v2 can download the video in the second link above and give me their opinion as to the comparable quality? 

About the power, I understand if I use a device with a power source that is not approved by the manufacture I will be tossing out the warranty.  I guess I was looking for an quick answer on how to give the unit the correct voltage using the 13-16 volts a car provides. 

And upon further researching this device I have another question.  When trying to record in car video would I need a view screen of some type?  Or, is there a one touch record button?

 
Thank you

I'm surprised no one has answered you this far.  olson-engineering.com has information and http://wiki.neurostechnology.com/index.php/User:ExNavy has done a lot of this kind of stuff.  You might try to PM him on this, he's normally on these forums, but maybe hasn't re-registered on the new forums yet.

Hi there Primaris,

Had a look at your link to the ebay camera and it would work fine i noted that the deal included a mic which would be an inline powered mic which again would be perfect for this application.  Just a note the Neuros leads are rca so 'might' need an addaptor for the lead form the camera. cost you a dollar from any Tandy store or alike.  Also the neuros records in stereo so get a 2-1 rca connector to get the audio on both channels again easy to get and cheap.

The recorder comes with a remote with a one touch record when the unit is live so no need for a screen in car just be sure of the position of camera.  Don't connect it upside down like I have in the past.

Power will have to come for a reguated source again shop around for a 12vt to 5vlt pos centre REGULATED source especially it you use the car bty as it can spike with rev changes etc.

The device is marketed as an in home unit so extreme sports will put any claims against defect at risk but I have done lots with mine without failure so live a little

PS there is a little red light on the recorder which comes on when its recording - very handy

Hi,

The video clip does not look to be very good quality and plays at a bit rate of 659kbs. This is much lower than the 900+ available on the highest Neuros setting so I would imagine that you will get better results. Naturally a higher resolution camera will give a better picture and there are some excellent 520 line cameras on the market.

Cheers

Pat

   Thank you very much for your answers 

FYI the video is copied from a Handycam Video 8 then edited in MS Movie Maker.  The original video is of course better quality.  Since my intent is to use Neuros video for the web all it needs to do is match the edited quality I currently have.

On a different note.  Where can I find tips on how to capture, edit, and publish video?  I stumble through it ok, but I'm always looking for better ideas.

I realize this thread is several weeks old, but I wanted to comment on picture quality since this is one of my few peeves with this device.

I use it on a motorcycle with a Rainbow BC33W bullet cam (480 TV lines).  I've tried setting the resolution to 640x480 and quality to the highest, but the video quality looks no better than when the quality setting is at "normal" (which is not that great).  It looks like 320x240 blown up - you can see all the jpeg-type pixel compression.  If I reduce the size to 320x240 it looks decent.  Or, if the video image has relatively little movement in it, it looks pretty good at 640x480.

Is this a limitation of the R2 processor to compress at high quality when there is a lot of movement?

Anyone else experience this?

Hey Mxracer95,
I noticed the same thing and it turned out to be my camera. I have a Sony Exview and noticed what you described,
especially at nite. It really shows pixels.
I got another bullet cam, (generic Taiwan manufacturer) for $90 and it has crisp images even at night. It is wider in
diameter.
I replaced the camera cable with double shielded and got even better results.

The Taiwan cam has a lower lux rating than the Sony Exview.

Maybe that helps, good post by the way, on the 12V pc supply, I never thought of that.

After finally upgrading my firmware to make use of the fixed auto-record feature, I tested recording from cable TV.  The pixel compression artifacts is the same.  Although, I was able to notice a slight clarity improvement from Fine to SuperFine, but even on SuperFine, the pixel compression kept the video quality far from broadcast quality.  But again, if I reduce the playback size to 320x240 (when recorded at 640x480) it does look pretty good.
