Bullet cam supply
Having just bought the 4Kam package I am looking at connecting it to the car 12v supply to do away with the separate 12v battery pack.
My question is do you need a 12v regulator or can you fit directly into the car electrics.
Some of the bullet cam suppliers say yes some say no!!!
Any sugestions

i would recommend you use a regulator, car voltage can vary quite a lot and im sure its best to protect delicate equiptment. I ran mine on batteries
specifically to keep it seperate from my bec regulator!

i was thinking exactly the same when i was in stainsburies paying out for 16AAA batteries
I'll be interested to see the responses

Depends what the input voltage range for the camera is, if its say 10-16V then you will be fine. But if its 11.5-12.5volts then you will need a
regulator.
Voltage regs are available off the shelf, they basically look like a big transistor and cost a couple of quid.

Plonk it on a heatsink in a box with a switch on, and you have yourself a 12v regulated output.
I did something similar with a 12v and 5v ouput on for my cam and recorder, works a treat.

You can buy a complete unit with switchable voltages for about £7 - got mine at a local accessory shop - for the price not worth taking the risk IMO
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

Having looked at the 4Kam website there 12v pick off is just 2 wires and a plug which they recommend for cars and bikes.

Maybe I should er on the side of caution and fit a regulator. I dont want to fry the cam having only just got it

They sell a wire implying you can wire it straight up to your car, which implies it has quite a wide operating voltage.
Also since they imply it's okay, then if it does go pop you've got a claim for a replacement surely.

Just got an e-mail back from 4Kam and they say that I can fit a regulator if I want but the camera can cope with an un regulated supply.
Problem solved.
