This involves following a subject on foot or in vehicles to monitor movements and activities throughout the day. Ideal for tracking behaviour and patterns.

Static Surveillance

Observation from a fixed position such as a parked vehicle or nearby property. Often used for monitoring addresses and proving cohabitation.

Progressive Surveillance

A highly specialised technique used to avoid detection when a subject may be surveillance-aware. Conducted in stages over time.

Technical Surveillance

We utilise advanced equipment to assist operations and improve accuracy, ensuring we never lose sight of the subject.

Professional Surveillance You Can Trust
