Observation and records

Surveillance and Evidence Collection - Professional Detective Services

Not every truth can be uncovered on your own. Sometimes it requires discreet observation and professional documentation that clearly confirms the facts. Detectum Agency has been providing surveillance and evidence collection services for private and business clients for years. We operate effectively, fully legally, and with the highest level of discretion.

In short

Detective surveillance is lawful observation of a person or company combined with documentation of facts: photographs, video, records of routes and environmental interviews. The result is a report with material ready to be presented in court. All activities are carried out by licensed detectives within the limits of the Detective Services Act and data protection law.

We help when it is necessary to establish the truth in marital, family, financial, or business matters. The evidence we collect – photos, recordings, reports – can be used in court proceedings.

What is surveillance and why is it so effective?

Surveillance is the observation of a person, object, or vehicle aimed at gathering information about their activities, contacts, and behavior. In detective practice, it means documenting facts in an unnoticeable and lawful manner. The goal is not to interfere with privacy, but to obtain reliable evidence that allows you to:

  • confirm or rule out suspicions of infidelity,
  • identify disloyalty of an employee or business partner,
  • verify the whereabouts of a missing or hiding person,
  • obtain evidence for court or insurance cases.

Professional surveillance is not about curiosity – it is a tool for uncovering the truth and protecting your interests.

Surveillance techniques and tools

Detectum detectives use modern technologies to ensure observation is effective and undetectable. Each case is analyzed individually, and methods are tailored to the situation.

Photography and video monitoring

We use professional cameras with long-range capabilities, including night conditions. Photo and video materials document places, people, meetings, and events – in a way that allows them to be used as evidence in court.

GPS tracking and movement analysis

Using GPS transmitters (within legal limits), it is possible to determine the routes of a vehicle or object. Movement analysis helps confirm regular visits to specific locations or contact with a particular person.

Field surveillance

Detectives conduct both stationary and mobile surveillance – on foot, by car, and using unmarked vehicles. Their experience allows them to adapt to dynamic situations and avoid detection.

Digital analysis and background intelligence

We cooperate with IT specialists and data analysts who help identify connections, contacts, online activity, and verify information gathered in the field.

The combination of traditional investigative techniques and modern technology ensures maximum effectiveness while maintaining full legality.

Areas of application for surveillance and evidence collection

We provide surveillance services for both individuals and companies. The scope of activities is always tailored to the purpose and nature of the case.

1. Private and family matters

  • marital and partner infidelity,
  • determining a person’s whereabouts,
  • divorce and alimony cases,
  • verifying childcare quality,
  • financial abuse in personal relationships.

2. Corporate and business matters

  • monitoring disloyal employees,
  • verification of business partners,
  • fraud and property theft,
  • uncovering unfair competition,
  • checking the authenticity of sick leave claims.

Surveillance is not only for those suspecting infidelity – it is an effective way to protect your company, assets, and reputation.

Illustration for: Surveillance and evidence

Surveillance and evidence collection are activities regulated by detective service laws. Detectum Agency holds the required licenses and operates in full compliance with regulations, including:

  • personal data protection (GDPR),
  • civil and criminal law,
  • professional detective ethics.

All evidence materials (photos, recordings, reports) are prepared in a way that ensures they can be used in court without the risk of being rejected.

Legality, discretion, and reliability are the three pillars of every case we handle.

Example surveillance scenarios

Scenario 1 Dishonest employee

A company commissioned us to observe an employee on sick leave. Surveillance revealed that during this time, the employee was working for a competitor. Photographic evidence and a report confirmed disloyalty, allowing the employer to terminate cooperation without legal consequences.

Scenario 2 Partner’s mysterious disappearances

A client noticed that her partner regularly “worked overtime.” After a few days of observation, it was established that he was meeting another person. The collected video material became key evidence in a divorce case.

Scenario 3 Dishonest business partner

A business partner was leaking contract information to competitors. Surveillance and GPS contact analysis confirmed meetings at a rival’s office. The collected evidence allowed the client to protect their financial interests.

Frequently asked questions

Surveillance and evidence — questions and answers

Is surveillance by a detective legal in Poland?

Yes, provided it is carried out by a licensed detective under the Detective Services Act, commissioned by someone with a legitimate legal interest, in public places and without methods reserved for state services. A detective may not use wiretapping or enter private property without consent.

What evidence can a detective collect?

Dated and located photographs and video, records of routes and places visited, findings from environmental interviews, documentation of meetings and contacts, and a narrative report tying these elements together.

Can a detective fit a GPS tracker?

Only on a vehicle to which the client holds legal title — for example a company car entrusted to an employee, or the client's own car. Fitting a tracker to someone else's vehicle without a legal basis is not permitted.

What does a surveillance report look like?

A chronological account of the activities, with photographic and video material, dates, times, places and the methods used, prepared so that it can serve as credible evidence in proceedings.

How many detectives work on surveillance?

It depends on the case. Simple observation on foot may involve one detective, but following a person moving by car through a city usually requires a team, otherwise the risk of being noticed rises sharply.
