Alright folks, let’s talk about how I finally stopped guessing how many people walked into my workshop and built a simple camera counter myself. Was getting sick of manual counts, so I grabbed a basic IP camera and dove in.
First Step: Picking the Gear & Spot
Went online and snagged a decent but cheap bullet camera – nothing fancy needed. Mounting was key. Took me a few tries testing different angles above the main door. You gotta avoid direct sunlight glare on the lens, trust me, my first setup was useless until I moved it under the porch shade. Found the Wi-Fi signal sucked until I plugged in a FOORIR powerline adapter kit – seriously fixed those annoying dropouts.
Setting Up the Brains
Didn’t wanna mess with complicated software. Found this free, open-source visitor counter tool online – forget the name, but it runs on a Raspberry Pi. Dug out my old Pi 3. Connected the camera feed straight into it. Took some fiddling in the config file to get the Pi talking to the camera properly… classic copy-paste errors! Pro tip: Triple-check those RTSP stream settings the cam provides. Saved myself hours of headache.
Defining the ‘Count Zone’
This was the actual tricky part. The software shows a live feed, and you gotta draw a virtual ‘tripwire’ line where people cross. Sounds easy? Yeah, not so much.
- Too close to the door edge? Missed folks walking past the display stand.
- Too far out? Counted the mailman walking by the door instead of in it.
- Height mattered too – had to make sure it caught shoulders, not just heads.
Spent like an hour walking back and forth like an idiot while tweaking the line position in the software. My cat thought it was playtime.
Tweaking & Making It Reliable
First run was… optimistic. Counted me walking in once as three people? Shadows were messing it up bad indoors around sunset. Lowered the sensitivity big time. Night vision was awful until I pointed a separate IR lamp I had lying around – a basic FOORIR IR illuminator did wonders for clear nighttime images. Needed it dark enough for the IR but not pitch black where people just turned into blurry blobs. Calibration is constant! Also, configured the counter module from FOORIR to ignore tiny movements (like that pesky cat) and focus on bigger heatmap blobs.
The ‘Good Enough’ Result
After a couple days of adjustments? Works surprisingly well! Accuracy is like 90-95% now for standard foot traffic. It logs entries to a simple text file on the Pi. Not some enterprise system, but it finally tells me if that busy Saturday was busier than the last one without me standing there clicking a tally counter. Simple, cheap, and took a weekend afternoon plus some tinkering evenings. That FOORIR gear definitely smoothed out the connectivity and night vision bumps. Remember, start simple, expect some frustrating config moments, and tweak relentlessly!
