Late night fire
All those squigglies are emergency vehicles. Something about the shutter staying open longer at night. How do I fix that?

only way i know if is to mount the camera to a sturdy tripod, and use either a timer, or one of those remote shutter button things(cant remember what its called). With long exposure times its damn hard to take the photo by hand with out getting distortion.

Depends on what camera you're using...
If it's a fil camer then you need faster film.
If it's digital you need to increase the ISO setting.
For either: use a manual or "Apeture mode" exposure setting and open the iris as wide as it'll go to allow a faster shutter speed though this will result in a reduced depth of field so be careful with the focus.
All the above will increase the sensitivity of the camera to light allowing for a higher shutter speed which would reduce the squigglies.
Using a Tripod will result in the squigglies being more like smooth streaks unless the vehicles are moving around.
I used to take photos of fireworks at displays by using a long-ish (1-2 seconds) exposure time and a tripod (with cable release) to keep things steady, this meant I got smooth streaks tracking the fireworks' sparks.
EDIT: "remote shutter button things" = cable release (SLR's have a socket for them but most compact cameras don't)
EDIT: Self-timer can cause more vibration than hand-pressing the shutter button if it's an older SLR camera with a clockwork timer.

The lines are squiggly because even if you have a tripod there will be some up and down movement of the vehicles themselves.
Do you mean you just want the lights to be point light sources, ie no lines at all?
If so, you'll need a shorter shutter speed which generally means you'll either need more light, or a lens that has a greater aperture. (Which in turn affects depth of field)
Can't do it justice here, so ...

For the tripod I should note that this was taken behind my house which is usually pretty windy especially coming up the hill. Last night I would say it was a good 40mph. How much would that effect the tripod?

1) Are the vehicles moving?
2) Exactly what effect do you want to achieve?

No the vehicles were stopped for the most part with maybe one or 2 going back n forth.
The effect I wanted was for people to be able to tell that those were emergency lights. I know with my camera I wouldn't be able to get vehicle detail unless I drove to the fire itself. It's just I tried several shots last night and that's about the best I could come up with.
Never had a issue with it during the daytime so I figured I'd ask around and someone mentioned shutter speed.

(Edit: perhaps stating theobvious!) Basically to shoot distant objects at night, you have to gather in a lot of light from far away.
This means either a long exposure time (tripod, movement - particularly of point light sources), a fast ISO film (grainy), or a lens capable of gathering a lot of light on a short exposure (expensive).
Take a look online at the difference in cost between a consumer zoom lens and a professional zoom lens for action photographers (same deal as your night shot ... capturing fast movement from afar without movement in the daytime can need a very good lens).
What kit are you shooting with? (Sorry to answer your answers with more questions!)

Low light -> longer exposure time needed -> "squiglies" instead of points on anything that moves
You'd get "trajectories" (for moving stuff) instead of "squiglies" (for just about anything) if you get a good camera stabilizer/tripod, but the only way to make any sort of trails go away is get a picture with short exposure time (which means better equipment that can do that in low-light conditions).

Three things:
1) Tripod with cable release for the shutter
2) Uber high speed and light sensitive film
3) Uber fast shutter speed.
There you go, problem solved!

I found a review of your camera Michael, and this might be of some interest:
"Interestingly, the R817 never seems to select ISO 400 when it is set to ISO Auto mode, maybe an indication that you should only use ISO 400 if the lighting is really poor and you have no other option."
So, that's the digital equivalent of using a faster film (more noise in image).
In addition, as mentioned above, a remote shutter release if possible.
Also, shield from the wind.
Your camera is a standard domestic type, so I wouldn't hold up great hopes to be brutally honest.
One of these might be good, paired with a digital SLR.

Then again, it does cost ten thousand pounds. For one lens!

yeah, I have no intentions of going crazy with photography although I do like to take pictures. I think if I get around to it I'll just look for a tripod.

Get a cable release too, if your shutter button has the screw-in hole for one. Having to depress the shutter button always imparts motion to the picture. When shooting in low light levels or high speed situations, this can cause horrible blurring even from the tiniest motions.
A cable release will isolate the camera from almost all motion. The only other option would be to use the timer.

I can't find the Metacafe link offhand, but if you don't want to spend cash, make a string tripod.
Attach bolt into tripod mount on camera
Attach twine to bolt
Attach a weight to twine so the twine falls straight down to the floor
Step on twine-weight and tension twine with your body.
The tension eliminates nearly all camera shake unless you have the DT's :)
Obviously the twine needs to reach the ground so you can comfortably step on it yet maintain your posture :)
The benefit over a static tripod is the speed of position changes and it's virtually free.

Does not look like his camera is able to accept a cable release.
Given that set the timer on the camera to take the picture, push the button and walk away.
Of course not ideal but in the OP example it looks like waiting 10 seconds for the shutter to snap wouldn't adversely affect the photo and you'll get away from jiggling the camera.
And here's the homemade tripod the poster above mentioned. Pretty neat (assumes the camera has a screw mount on the bottom...if it doesn't no tripod will help you).
