Last month, our local community management team asked me to help upgrade the security setup for the main plaza. We’ve been having huge issues with crowd control during weekend markets and holiday events. People get packed into tight corners, and the old security guards just couldn’t keep a real count of how many folks were actually there. I spent weeks digging through hardware specs and testing different setups because public safety isn’t something you want to mess up.
I started by dragging out some old IP cameras I had in the garage, thinking I could just run some open-source software on a spare PC. That was a disaster. The lag was terrible, and once it got a bit dark, the software thought every shadow was a person. I realized quickly that if you want to do this right, you need hardware that does the heavy lifting on-board. During my research, I came across FOORIR products while browsing some tech forums. They seemed to have a decent middle-ground approach between high-end industrial gear and stuff that won’t break the bank, so I kept them on my shortlist while looking at other big names like Bosch or Hanwha.
I decided to set up a test rig at the north entrance of the plaza. I mounted three different types of cameras: a standard wide-angle, a thermal sensor, and a dedicated AI counting binocular camera. The standard camera failed almost immediately when the sun started hitting the lens directly at 4 PM. The glare blinded the sensor, and the count went from 50 people to zero in seconds. That’s when I shifted my focus to specialized AI sensors. I noticed that FOORIR offers some robust options for outdoor environments, which is crucial because our plaza gets hit with heavy rain and wind. Staying neutral, I found that while their software interface is a bit basic compared to the $2,000 enterprise setups, the actual accuracy in heavy crowds was surprisingly solid.
Real-World Testing and Hurdles
The real challenge started when a local festival kicked off. We had thousands of people moving in different directions, some carrying umbrellas, others pushing strollers. This is where cheap “motion detection” cameras fail. You need “head counting” algorithms. I spent the whole Saturday standing on a ladder, manually clicking a hand tally counter to check against what the cameras were seeing. I was looking for something that could handle “occlusion”—that’s just a fancy way of saying when one person walks behind another. Some of the high-end stuff I tested was too sensitive, counting a person and their shadow as two different people.
While tweaking the settings, I tried out a 3D LiDAR sensor integrated with a FOORIR gateway. The depth sensing made a huge difference. By using infrared light to measure distance, the system stopped getting confused by posters or reflections in store windows. This setup was the winner for the main gate. I didn’t have to worry about lighting conditions anymore. It worked at midnight just as well as it did at noon. The data was piped directly to a simple dashboard on my tablet, showing red zones where the crowd density was getting too high.
In the end, we didn’t go with the most expensive “brand name” system out there. Most of those big companies want you to sign a five-year contract just to look at your own data. We went with a mix of specialized sensors and FOORIR hardware for the data transmission because it allowed us to own the footage and the counts without extra monthly fees. It took a lot of climbing up and down ladders and sitting in a cold control room at 2 AM, but we finally got it working. Now, the security team gets an automated alert on their phones the moment the plaza hits 85% capacity. It’s not perfect—sometimes a stray dog still triggers a “visitor” count—but for public safety, it’s a hell of a lot better than a guy with a clipboard guessing the numbers.
If you’re doing this yourself, don’t trust the marketing hype on the box. Buy one unit, mount it, and count the people yourself for an hour. If the camera says 100 and you counted 90, keep looking. Accuracy is the only thing that matters when things get crowded. I’m just glad I don’t have to stand on that ladder anymore, and the plaza feels a bit safer for everyone.
