Face surveillance is a service frequently requested by individuals and businesses for various reasons — suspicions of infidelity, disappearances, employee monitoring, and more. Before making a decision, it is important to understand the cost and the steps involved in the process so you can make an informed choice.
How much does it cost
Based on data from various Greek agencies:
The hourly rate typically ranges from ~€50 to ~€180‑200 per hour for monitoring an individual, depending on the area and complexity.
For daily surveillance services, the cost can rise from €500 to several thousand euros.
Additional charges may apply for overnight stays, travel (especially outside of Attica), use of specialized equipment (e.g. night vision cameras, GPS trackers), or the addition of technological tools.
Process followed
Initial meeting / assessment
Details of the case are discussed: who you want to monitor, why, what hours, which areas, what information is already available.
Surveillance planning
Selection of methods (physical monitoring, digital investigation, use of equipment), determination of time and cost.
Execution
Surveillance, collection of evidence (photos, videos, timelines), use of technology if needed.
Reporting / documentation
Delivery of a report to the client with all the data, written evidence, possibly for use in legal proceedings if required.
Legal framework & ethics / discretion
The private detective must operate within the law, respect privacy, and ensure that nothing illegal is used (e.g. illegal wiretapping).
Monitoring a person is not just a matter of cost but also of responsibility. Proper evaluation, transparency in pricing, and thorough documentation form the foundation of a safe and legal investigation.
