Case Study: How a 300-Camera Upgrade in Barcelona Cut Theft by 41%—and What It Means for Your Next Project

The Challenge

Mercat Central de Barcelona, a 19th-century iron-and-glass market, welcomes 45 000 visitors a day. But its narrow aisles and heritage façade made conventional CCTV towers impossible, and legacy analog tubes gave guards nothing but grainy silhouettes after 6 p.m. Shoplifting losses hit €1.2 M in 2023 alone.

The Gcraftsman Solution

Working with local integrator TecnoSeguridad, we replaced every analog feed with 4 MP varifocal domes (GC-VD4X) and 12 MP fisheyes (GC-FE12) in custom matte-black housings that blend into the cast-iron trusses. Key innovations:

• 180° corridor mode: A single fisheye now covers three 40-m aisles, cutting camera count by 38%.

• AI-powered “shopping-bag left-behind” algorithm: Alerts guards in <2 s when a bag is unattended for 60 s, reducing false bomb scares.

• PoE++ daisy-chaining: Two Cat6 cables power 18 cameras along each beam, eliminating the need for conduit drilling in a protected UNESCO façade.

• Remote firmware sign-off: City heritage officers reviewed low-light footage via VPN before granting final installation permits—no scaffolding needed for second visits.

The Results (6 months post-installation)

• Theft incidents down 41% (market security log).

• Insurance premiums cut 18%.

• ROI achieved in 11 months—two months ahead of forecast.

Why this matters to you

Every city has a Mercat Central—an architecturally sensitive site where aesthetics, compliance, and performance collide. Gcraftsman’s flexible optics, discreet housings, and AI firmware allow integrators to quote heritage boards with confidence. And because we keep 200+ units of each SKU in our Barcelona forward warehouse, TecnoSeguridad received the last 30 cameras overnight when the city accelerated the go-live date.
