Static cameras are operational 24/7, as long as a camera is installed and it has film. Vans only work dawn to dusk, although Cumbria (& somewhere else 
) have been trialling cameras that work in the dark

Are speed cameras still film? I just assumed they would be digital by now.
If they are does anyone know how they are downloaded?
Not asking for any illegal reason just wondering if they are digital and fully automatic download to a central system somewhere.

The new Mini-Gatso's and Spec's I believe are digital with remote downloading. AFAIK the older Gatso's and Truvello's still use film and have to be manually loaded and processed.

I was under the impression the vans cameras didn't work in the dark but my sister normally passes a van on the way home from work in the dark. Hopefully someone can clear this up once and for all.

As I understand they use a invertor to convert video from black to white, so that registrations can be read. I am not sure that this has been type approved by government, but when did that stop the scammers topping up their pension contributions

I'm sure a laser gun would have no problem in obtaining your speed even in the dark as its works by receiving pulses of light produced by an infra-red laser diode reflected from very highly reflective surfaces on your car such as the number plate. So getting the speed isn't a problem in the dark
What i think is probably the limiting factor is the digital camera equipment used to photograph the front of the car. It would require good enough illumination to ensure a usable picture on the recording equipment. Not much use getting a speed reading if you can't photogrpah the offending car. Although some digital cameras are very sensitive to light now so working in low lighting (such as street lighting) wouldn't be an isssue.

Good question. I'm not sure if there is a minimum wattage limit on the bulb for the number plate. I reckon that as long as the police can read it at night you'll get away with it.

- 1. Number:
- 2. Position:
- 3. Angles of visibility:
- 4. Alignment:
- 5. Markings-
(a) A motor vehicle first used on or after 1st April 1986 and a trailer manufactured on or after 1st October 1985:
(b) A motor vehicle first used before 1st April 1986 and a trailer manufactured before 1st October 1985:
No requirement
- 6. Size of illuminated area:
- 7. Colour:
- 8. Wattage:
- 9. Intensity:
- 10. Electrical connections:
- 11. Tell-tale:
So, no minimum wattage, but a vague requirement to "adequately illuminate"
