Regulatory framework
The framework that decides whether a project works
The question that determines whether a road enforcement project works is not which camera is bought. It is who may sanction on which road, on what evidence, under which standard, and where the revenue goes. We set out the framework here as we understand it, with the sources in plain view.
Two chains of authority over one road
Enforcement of speed and driver conduct runs through the public-security chain: the Guardia Nacional on federal roads, state or municipal traffic authorities elsewhere. Enforcement of weight and dimensions runs through the infrastructure and metrology chain: SICT (DGAF) and CAPUFE on federal roads, state transport authorities elsewhere. Two distinct chains over the same asphalt, with different standards, competences, and procedures. Our systems are designed accordingly.
Dynamic weighing: NOM-198-SCFI-2018
A mandatory standard, published in the DOF on 9 March 2020. It sets the technical requirements, components, specifications, calibration and verification methods, and installation-site characteristics for dynamic vehicle weighing and dimensioning systems. It applies to anyone who installs, operates, or administers one. Model approval is processed through CENAM. The standard is not equivalent to any international standard: there is no automatic recognition of foreign certifications. Related standards: NOM-012-SCT-2-2017, NOM-008-SCFI-2002, NOM-001-SEDE-2012.
Speed and photo enforcement: what exists and what does not
No mandatory NOM for speed-measuring devices exists in Mexico. PROY-NOM-215-SCFI-2017 was published as a draft and never finalised. Technical infrastructure standards do exist within the SICT framework: N·EIP·1·01·011 (plate recognition cameras) and N·EIP·1·01·012 (automatic incident detection). The legal defence of a citation is therefore built on the chain of evidence and on validation by an authorised agent, not on a metrological certificate that is not currently issued.
Agent validation: not an obstacle, but the correct design
Several Mexican jurisdictions require an authorised agent to validate the evidence before a citation is issued; others expressly permit photo-enforcement by certified electronic equipment. Our systems operate well under either regime, because in no case do they sanction on their own: they produce a case file and hand it to whoever holds the power to sanction.
Revenue
Revenue from citations belongs entirely to the authority. We take no share of it. Our commercial model is supply and service, not fine-sharing.
Our role is to produce technical evidence that is defensible, traceable, and auditable. Nothing more, and nothing less.
A note on method
A note on method. We do not publish third-party effectiveness figures as if they were our own results, and we do not present foreign certifications as equivalent to Mexican ones. If a fact is not verified, we do not publish it.
