Discreet, lawful and documented to evidential standards.

Exero Group s.r.o. carries out surveillance and activity verification in Prague, across the Czech Republic and, where a matter requires it, elsewhere in the European Union, for law firms, businesses and private clients. Every deployment starts with a written lawful purpose, an operational plan and a proportionality assessment. Before an operative leaves the office we answer four questions in writing: who the subject is, what observable conduct will be documented, which legitimate interest justifies the intrusion, and what measures will limit incidental recording of uninvolved people. Observation takes place in public space only. We do not trespass, intercept communications, fit tracking devices or use databases reserved for the police. We deliver three kinds of work: mobile surveillance of subjects in motion, static observation of a defined location, and counter-surveillance to detect hostile coverage of executives, witnesses or legal teams. Each operation closes with a written report, a time-stamped and hashed media archive and an exhibit catalogue. Deployment timing depends on the brief, the location and team availability, and we confirm it in writing before work begins. What the findings mean for your matter remains a decision for you and your advisers. ## Core Capabilities ### Mobile Surveillance Multi-vehicle teams across CZ, SK, AT, DE, PL. ### Static Surveillance Discreet long-term observation from documented vantage points. ### Covert Foot Coverage Urban deployments with rotating operatives. ### Time-Stamped Reporting Daily logs, video index and exhibit catalogue. ### Cross-Border Operations Coordinated deployments with local partners abroad. ### Counter-Surveillance Detection of hostile surveillance against your team. ## Technical Methodology 1. 1 ### Briefing & Legal Basis We document the lawful purpose, scope and proportionality before any operative is deployed. 2. 2 ### Reconnaissance Vantage points, traffic patterns and likely subject behaviour are mapped in advance. 3. 3 ### Deployment Two or three operative teams maintain discreet coverage with rotating roles to avoid burn. 4. 4 ### Capture & Logging 4K video and stills are time stamped; the observation log notes every change of position. 5. 5 ### Reporting Daily after-action notes and a final structured report with exhibits. ## Regional Context & Compliance ### Public-space rule Observation is conducted in public space only; no trespass, no concealed audio, no devices that intercept communications. ### GDPR balancing test Each engagement carries a written Article 6(1)(f) legitimate-interest assessment. ### Personality rights We respect §81-§90 of the Czech Civil Code and minimise capture of uninvolved third parties. ## Specific Use Cases Audience ### Private Clients Document observable conduct relevant to a family, matrimonial or personal matter. Audience ### Legal Counsel Build evidence packages for civil and family-court matters. Audience ### Risk Managers Document unauthorised activity by employees or contractors. ## Frequently Asked Questions ### What is covert surveillance? It is the discreet observation and documentation of a subject in public space without alerting them, conducted under a documented lawful purpose by trained operatives of a licensed agency. ### How much does surveillance cost in the Czech Republic? A two-operative mobile team typically runs EUR 950-1,400 per operational day, including vehicles, equipment and post-day reporting. ### Is private surveillance legal in the Czech Republic? Yes, when conducted in public space by a licensed agency under a documented legitimate interest. Audio interception, trespass and use of police-only databases remain prohibited. ### Will the subject know they are being watched? When operations are properly resourced, no. Counter-counter-surveillance protocols and operative rotation are designed to keep coverage invisible. ### How do you preserve evidence? Raw video and stills are hashed and archived under chain-of-custody; working copies are used for redaction and reporting. ## Related Services ### Private Investigations Discreet fact-finding for individuals and families: matrimonial concerns, custody-related matters, missing persons and background checks.
