Ohhh, Doc. I am concerned about you. If you get an email from a Nigerian prince, ignore it. If you get an email similar to the one I have received numerous times per year for the past eight years, ignore it. They don't have any videos of you jerking it.
Your speed/red light camera is a similar scam: "We have video evidence of you running a red light, and we are going to send it to your insurer so your rates go up $50 per month. But if you send us $200, we will not contact them." Bogus. 100% bullshit.
Do you know how easy it is to get the make/model/color of your car, photoshop that same vehicle at a major intersection in your area, and claim it is picture evidence of you breaking the law, so you better pay this random company? Mass mail those out, and I assure you that 3% - 10% of people who receive that professional looking letter will send that $200 payment.
