However, with all the technology on board the N900, is it possible that it could detect when a camera is actually pointed at it. Perhaps the proximity sensor could detect that the lazer is hitting it or something.
there is an application i don't recall its name but its on every phone on the planet except n900 (java - symbian - iphone - ....) where users puts the locations of the cameras they saw or know about it somehow and place it on the map, other users can rate this info how true it is (and there are many users so you will be sure about the cams in that location),,this map works in that application's gps with alerting voice, so its not just google earth there are many participants. your only shot is to use any java emulator to run that application.

The app you speak of is RoadRunner, it uses the location that people have put on Google Earth or that authorities have put up, this is available on N900 Now. However it only tells you when you are in a zone, that does not mean that the van is there.
I want to know and have a right to know if someone is pointing a device at my car tracking my personal information.
camera detectors are completely legal in many countries and are used to reduce accidents not just to get out of speeding tickets.

Legal or not, what you want is a radar detector - most devices either use radar, or literally laser-like beams, or they're CAMERAs in that they just record light that comes in - not send any out. Here's the problem with each:
Radar - requires special gadgets to detect the frequencies you're looking for. N900 hardware can't do it, as far as I know, and can't even come close.
Laser - is actually a tightly focused light beam. Either it hits the N900's light sensors, or it doesn't - if those sensors can actually detect the wavelengths used, can take it without giving an error from it being too bright, and can distinguish it from all the other wavelengths of light, you still have to get lucky and have the N900 get hit directly with the beam. And not just the N900, but the exact camera lens / brightness sensor / proximity sensor, which are the only three remotely likely to be able to detect it.
Camera - an actual plain camera, that just records light, is invisible in terms of emissions of the kind N900 hardware could pick up, unless it's in night vision mode and blasting infrared everywhere. In which case even if the N900 can detect those wavelengths, it can't necessarily distinguish them from a flashlight.

Thats exactly what I am wondering, by the sounds of it its not possible.
Basically most Police use either Cop on road holding gun, if it records you over limit he pulls you. Other is van at side of road, again lazer detects you speed, if you are over limit the the normal camera that on the van take your picture, this is the same process for a fixed speed camera, its a lazer camera combo.
Its a pitty that this is not possible as would be very handy to know.
The legals etc I only mention as while i dont speed I just want to know whats going on around me but there are a lot of do gooders and just annoying people that just have to stick their ore in.
Thanks for the info

Ok looks like not possible....lets close this then.
Regarding Sygic..good to know..RoadRunner Id say is still best/only standalone app to warn of zones and its light too....
Thanks for everyone for commenting

I know we have RoadRunner and its a great app, however the problem with this is that its based on Google Earth KML files etc, so it can get out of date and it just alerts you that you are in a zone.
However, with all the technology on board the N900, is it possible that it could detect when a camera is actually pointed at it. Perhaps the proximity sensor could detect that the lazer is hitting it or something.
It would be really cool to have built in detector like this.
Any ideas....if possible anyone want to make it ?
Thanks
