Technical Surveillance

What happens when you are not around? Technical surveillance from Andrew Crown Investigations lets you know.

What happens when you are watching does not always reflect what happens when you turn your back.

With that in mind, technical surveillance lets you monitor people using the latest investigative technology, from CCTV cameras to phone and internet monitoring devices.

Andrew Crown Investigations combines powerful technology with rich analysis to let you see what is really going on, even where obstacles would prevent traditional surveillance methods.

Put Your Trust in Technical Surveillance

Everything we do is centred on trust and ethics. That remains the case when it comes to technical surveillance.

Whether you are using high visibility cameras as a deterrent and monitoring tool, or need to see what is going on in an email thread, our technical surveillance team balances intelligence gathering against intrusion.

So you get the information you need and the transparency you seek, without compromising your integrity.

Our technical surveillance services include:

  • Covert CCTV and audio
  • Debugging and bug sweeping
  • Telephone, computer and mobile phone surveillance

We use one or more of these platforms to deliver a complete technical surveillance report.
