someone told me the flashing ones are surveillance. they sense the motion of the car and take photos of each and every car approaching them. they id car registration among other stuff. linked to registrar of motor vehicles (among other database) they can even know it is masukuma's car heading to a server farm. the someone further claimed that it is easy to know the last known location of any vehicle they are after in a 'blink' (as long as it is within the area covered). do note that it was in a bar and i was very drunk and the someone was even drunker than me. so cannot vouch for any of it.

The best form of policing, and its very effective where its used, is not where people commit crimes, are arrested and jailed. Its where fear is instilled into people's brains and hence commit no crime.

Example.
Place a spy police in front of a bank, thieves will try to steal, maybe successfully or not.

Now, place a uniformed cop outside the same bank, with guns etc. Every thief will notice, and will not attempt to steal.

In short, the cameras are a means of deterring you Subaru owner from commiting a traffic offence more than arresting you if you commit that offence.

Those are SPEED CAMERAS.... they take photos of vehicles that are coming - OK! Could they be used to check who was driving the vehicle - yes. but their primary reason of manufacture is SPEED detection.
The real surveillance ones are the ones safcom setup. they look like CCTVs. They can zoom - change direction like 360 degrees. These are the ones that are useful 'kutafuta watu'. The flash in the speed cameras is for usiku - number plate lazima ikuwe legible. The big issue i have with the 'speed' cameras (over and above that they have been placed in places where the road naturally limits speed) is that we don't have a way to really send the results of the system to the unsub. where they have been implemented well - the results are sent to your mail box and then you go pay ama contest in court. hapa sasa kabla upatikane ni lini?

Hahahahaha. I thought i was the one committing that crime alone.

It took me 3 years to change my langalanga from the previous owner to mine.

Its normal behavior kabisa, even insurance issues cover based on a sale agreement and old logbook.

Until that logbook process isnt automated and instant, such photo collecting is worthless.

Its the same case with most issues in Kenya...they are left inefficient/manual so someone can EAT!
