📹 Here is How I Discover Surveillance Cameras in a City (OSINT)

Most people assume surveillance cameras are only visible if you are physically there or if you have special access.

But in OSINT, you can often identify where cameras are located just by using open sources.

And that alone can give a lot of situational awareness.

🧠 Start with the city
I choose the area I want to analyze.

🔍 Search mapped camera data
Instead of looking for footage, I look for publicly indexed surveillance and traffic camera locations.

📊 Build an awareness map
Even without viewing feeds, knowing where cameras are located helps understand which areas are more observable than others.

🎯 Real-life example
I analyze a city and map out surveillance camera locations around major roads and central intersections.

I notice that some key entry points are heavily covered, while other surrounding areas have limited visibility.

That helps me understand where activity is more likely to be observed or recorded by the public or authorities.

In OSINT, visibility is often as important as access.

What’s your approach to mapping urban surveillance coverage?

P.S. ♻️ Repost if you found this helpful.

I've been working on this for ages in various countries: the story of the intelligence buildup to Putin's 2022 invasion. How did the US and Britain find out so much, and why were Europe and Ukraine sceptical.

It's a long one:
