Evidence Gathered from Surveillance, Documentation and Surveying

A company cannot take legal action on a hunch. We believe companies have the right to know when a member of their team is not adhering to a contract or is committing foul play. ISRA has extensive experience in undertaking discreet surveillance and has the technical resources to produce documentation that separates facts from suspicions.

Businesses commonly require surveillance services when they suspect issues among employees or contractors. Examples of this are: fraud, pilferage or other cases where there is a need for professional documentation of someone’s activity by the means of photography, videography or sound recordings.

When is Surveillance for a Company Necessary?

Different industries hire ISRA for different reasons. Law firms hire ISRA to acquire factual evidence for a court case while other companies do so if they have suspicions that an employee is committing foul play. This means this person could be leaking valuable, secretive information to a competitor or could be claiming unjustified sick leave. ISRA also works with authorities such as social institutions to confirm whether or not people claiming disability compensation are eligible for it. We also provide tailored services for individuals needing surveillance services. For more information visit our Surveillance for Individuals Page.

Technical Surveillance Vs. Physical Surveillance

Technical surveillance uses technology to track and locate a person. This can involve numerous techniques and each case requires specific equipment. Physical surveillance is the act of physically tracking someone. This means, one of our experts would physically track, survey, photograph and document a person’s movements. Both surveillance techniques are efficient methods of tracking a person and these can be tailored to our clients needs.

Our surveillance team is experts and the leading in the field and have at least 10 years of experience.
