12v Voltage Drop?

Morning!
I'm looking to install CCTV at the front of the house (long story,
involving kids, eggs, and rather bizarrely, comedy penis's drawn in
butter on the car!)
I bought a camera which runs on 12v and comes with a transformer. But
the lead on the transformer is only about 7' long, which for an outdoor
camera makes it pretty hard to position and still plug in.
I have 3 options I guess, site it somewhere else, buy a new transformer
with a longer lead, or extend the existing one.
My question is, if I simply cut the cable and extend it, will there be a
noticeable drop off in voltage to the camera?
Cheers

Ive got a camera with 6 IR leds on about 30M of .75mm 3 core screened
flex, had it lying around.
Biggest drain in a camera think is probably the LEDs, some have a
small wirewound resistor that is meant to act as a heater to stop
misting.
Speaker cable is a good low cost cable for the power and RG58/59 is
lot thinner than standard coax if you need to extend the signal.
