THE SILICON ARSENAL

Engineered for the absolute extremes of Southern Africa. 83% of commercial rangeland and wildlife reserves sit in the cellular void—where imported consumer trackers die in mountain ravines and dry riverbeds.

Every node below runs autonomous Sub-1GHz Wi-Fi HaLow and kinetic mesh telemetry. Zero SIM cards to recharge. Zero US Dollar cloud fees. 100% sovereign hardware reporting directly into your on-premise or sovereign cloud HOTEYE 3D GIS.

"In 1989 on the Sand River, we learned the brutal physics of the veld: a 450kg Boran bull rubs against camelthorn trunks with crushing torque. Cheap plastic enclosures snap in 48 hours. If hardware cannot survive feedlot slurry, lightning strikes, and 65°C Karoo heat, it does not belong on your boundary."

TACTICAL ECONOMICS & DETERRENCE DOCTRINE

THE 1:9 DUAL-COLLAR MOAT

Why spend R1.95 million tracking 1,000 cattle with fragile individual subscriptions? HOTGROUP deploys 10% active smart collars combined with 90% laser-etched decoy sentinels. Identical in weight, tooling, and serial typography—paralyzing theft syndicates while preserving over 75% of your capital.

CONVENTIONAL INDUSTRY MODEL FRAGILE & COSTLY

100% Active Collar Deployment

Every single animal carries an expensive foreign-made tracker requiring individual cellular SIM contracts, fragile antennas, and recurring monthly cloud fees.

100 Smart Collars (10%) + 900 Decoys (90%)

Every animal in the herd wears a collar. 10% are active HC-C1 Sub-1GHz nodes tracking herd velocity, water troughs, and panic flight. 90% are HC-D1 decoys identical in weight, casing, and serial engraving.

FIELD WORKFLOW VELOCITY

THREE-STEP VELDFIT DEPLOYMENT

Zero complex field programming. No laptop in the crush pen. Designed for fast livestock processing during morning branding or dipping.

01
CRUSH PEN REGISTRATION

Scan & Bond (8 Seconds)

Scan the laser-etched QR code using the HOTEYE mobile app. The collar node bonds instantly with the animal's ear tag, breed pedigree, and pasture paddock.

02
TAMPER & BREAKAWAY FITMENT

UV Shear Seal Lockdown

Fasten the ballistic polyurethane strap with calibrated 65kg safety breakaway shear. Internal optical fiber circuit arms the anti-cut tamper detector automatically.

03
AUTONOMOUS MESH LOCK

Live 3D Telemetry Sync

Release animal into the camp. Within 12 seconds, the node acquires dual GPS/Galileo lock, handshakes with the nearest koppie repeater, and glows green in HOTEYE 3D GIS.
