AI video analytics in your café: how many coffees does each barista make?

TL;DR. Your existing CCTV can become a bar efficiency dashboard. With simple AI software (no new hardware, no face recognition), you can measure how many coffees each barista makes, how long customers wait and what queue patterns emerge. First dashboard: free.

The scenario you didn't know you could fix

You run a café in San Sebastián. Three baristas. Old security CCTV. Every morning, the same question:

"Who's slower today? Why's there a queue at 8:30?"

Without data, you guess. But your CCTV already captures everything. You just need software to read it.

"We installed the software last week. The 2018 CCTV saw everything. It just needed AI to interpret it." — Jabi, owner of Café Bar Txepito (Hernani).

How it works (no new cameras needed)

1. Your existing CCTV streams video (analogue or IP).
2. An AI software (OpenCV + YOLO) analyzes the flow of people in real time.
3. A dashboard shows metrics with colors (red = alert, green = OK).

No face recognition at all. Just detects:

• Hand movements (coffees made).
• People (blobs, not faces).
• Queue patterns.

Cost: AI software: 49 €/month. New cameras: €0.

Metrics it measures (and how to read them)

Real dashboard example (Café Bar Txepito)

The Hernani café saw this after 1 week:

Insight: Markel was the bottleneck. Reorganizing the bar cut queues by 38 %.

Privacy guaranteed (and legal)

This tech does NOT use face recognition. AI models (YOLOv8, Detectron) detect:

• Human silhouettes (not faces).
• Hand movements (not identities).
• Flow patterns (not personal data).

Will comply with GDPR and LOPDGDD if you:

• Inform staff and customers (notice at the door).
• Don't store footage, only aggregated metrics.
• Delete data within 7-30 days (software config).

"Never saw faces. Just blobs and moves. Legal and safe." — Jabi, Txepito.

Real case: Café Bar Txepito (Hernani)

• CCTV: 2018 analogue (existing recorder).
• Software: Sensive Go (49 €/month).
• Installation: 2 hours (just connect software).
• Results in 30 days:
  • Avg wait time: 42 sec → 28 sec (-33 %).
  • Cups/hour: 105 → 120 (+14 %).
  • Walk-away customers: 8 % → 3 %.

"The AI didn't replace my barista. It helped me organize the bar better." — Jabi.

Quick guide: 5 installation steps

Step 1: Check your existing CCTV

You need:

• A camera with a clear view of the bar and waiting area.
• Video output (HDMI, USB, or IP on local network).

No 4K needed. 720p works for AI software.

Step 2: Choose AI software

Step 3: Install the software

Connect the video output from your CCTV to a mini PC (Intel NUC) or install the software in the cloud. The software analyzes video in real time. No technician needed.

Step 4: Define zones and KPIs

• Zone 1: Bar (count coffees).
• Zone 2: Queue (measure wait time).
• Zone 3: Entrance/exit (walk-away customers).

Step 5: Measure and optimize

• Week 1: Software learns (messy data).
• Week 2: Clear patterns.
• Week 3: Optimize (reorganize bar, shifts).

Real cost: AI vs new hardware

AI pays for itself in 1 month: 10 extra coffees/day × 1 € = 300 €/month.

In summary: 3-step plan

1. Check your CCTV. One clear bar view → ready.
2. Try 15 days free. Sensive Go or Deep Sentinel, no card.
3. Measure 3 KPIs: Coffees/hour, walk-aways, peak queue.

"Efficiency isn't felt. It's measured. And your CCTV already sees everything." — Retail Tech Journal.
