F355GTS Posted January 19, 2003 Share Posted January 19, 2003 I'm using an RF Concepts bullet cam which is currently fed by a block of Ni-MH rechargeables totalling around 10.4v, batteries are rated at 1700 mAh. The camera will run at anything between 8v and 15v and the manual suggests the operating current is 130 mAh input regulated. Anybody know if I can run it straight off the cars 12v electrics? or do I need some sort of regulator to reduce the current? Mark Link to comment Share on other sites More sharing options...
mav Posted January 19, 2003 Share Posted January 19, 2003 I too have recently bought one of these bullet cams, and was wondering the same. It will runn off Duracells for now. How long will tehy last Mark? Is it not worth trying some 2100mAh rechargeables? Link to comment Share on other sites More sharing options...
Andrew Dent Posted January 19, 2003 Share Posted January 19, 2003 Mark A regulator will not reduce the current. It will take a higher voltage and stabilise it into a lower voltage. There are low drop our regulators about which will drop about 1v, but typical is around 3v. I've never looked at the supply with a scope, but with that battery on board, I would have thought you would be able to run straight off the car +12v. Hopefully someone who has done this will be along to correect me. Andrew 4 wheels on my 7 Link to comment Share on other sites More sharing options...
F355GTS Posted January 19, 2003 Author Share Posted January 19, 2003 Mav it lasts all day on the 1700's it would just be easier to wire it in, They suggest it will last about 10 hours on 8 AA Alkaline or 1 hour on a single 9v Alkaline Mark Link to comment Share on other sites More sharing options...
Ian Barkley Posted January 19, 2003 Share Posted January 19, 2003 Sorry to hijack this thread temporarily.. Can you tell me if there is a quality loss in using a bullet camera over the 'normal' video camera lens? Do you set the exposure? white balance? focus? or are they fully automatic? Thanks Ian Link to comment Share on other sites More sharing options...
Red SLR Posted January 19, 2003 Share Posted January 19, 2003 From my calculations you should get about 12 hours. I ran my bullet cam off a 12v gel cell - it was about 2.5 A hr I think. However it did not like the charging cycle so I have now switched over to a battery box with AAs. I am hoping to get it all up and running again around march.

charlie1 Posted January 19, 2003 Share Posted January 19, 2003 I wired mine to the battery and have had no problems. Link to comment Share on other sites More sharing options...
F355GTS Posted January 19, 2003 Author Share Posted January 19, 2003 thanks guys looks like it will work then, I'll give it a go Ian I've just bought the 'better' Sony CCd type and quality is very good, probably not quite as good as Video lens but plenty good enough. Exposure, white balance etc are automatic Mark Link to comment Share on other sites More sharing options...
