Advanced Surveillance Techniques

Next-Generation Surveillance Equipment

Surveillance is a fundamental aspect of private investigations, and technology has significantly enhanced its effectiveness. High-resolution cameras with night vision, motion detection, and long-range zoom capabilities allow investigators to capture clear footage under any conditions. Miniature hidden cameras, disguised as everyday objects, enable discreet monitoring without drawing attention.

Drone Surveillance for Hard-to-Reach Areas

Drones have revolutionized surveillance, allowing investigators to track movements from the sky. Whether monitoring secluded properties, conducting asset searches, or discreetly observing a subject’s activities, aerial surveillance provides unparalleled coverage. Peakpi ensures that drone usage complies with Australian privacy laws, collecting evidence legally and ethically.

GPS Tracking for Movement Analysis

GPS tracking is one of the most effective tools for monitoring a subject’s movements. When legally permitted, these devices provide real-time location updates, allowing investigators to track behavioral patterns. This technology is invaluable in cases of infidelity, fraud, and corporate disputes, offering detailed movement analysis and geofencing alerts when a subject enters or leaves a designated area.

Digital Forensics & Cyber Investigations

Recovering Digital Footprints

A person’s digital activity can reveal more than what’s immediately visible. Investigators use advanced forensic tools to retrieve deleted messages, call logs, emails, and browsing histories. This information is critical in legal cases, financial disputes, and background checks, providing evidence that might otherwise remain hidden.

Social Media Investigations

Social media is a goldmine of information. Investigators use AI-driven analytics to track user behavior, uncover hidden relationships, and verify online activities. From identifying fraudulent social media accounts to detecting inconsistencies in testimonies, these tools offer powerful insights into a person’s digital presence.

Deep Web & Dark Web Monitoring



Cybercrime and illicit transactions often occur on the dark web, which traditional search engines cannot reach. Experienced investigators navigate encrypted forums and hidden marketplaces to uncover stolen identities, financial fraud, and corporate data leaks, helping businesses and individuals protect their assets.

Audio & Voice Analysis

Covert Audio Recording for Discreet Evidence Collection

Miniature audio recorders hidden in everyday objects enable private investigators to capture critical conversations. These recordings can be used in cases involving corporate fraud, legal disputes, and workplace harassment, providing undeniable evidence to support claims.

Voice Stress & Lie Detection Technology

AI-powered voice analysis tools can detect micro tremors in speech patterns, helping assess whether a person is being deceptive. Unlike traditional polygraph tests, these tools analyze vocal stress levels, providing a scientific approach to lie detection during interrogations or interviews.

Artificial Intelligence & Predictive Analytics

Facial Recognition for Identity Verification

AI-driven facial recognition software helps investigators identify individuals by matching them against extensive databases. This technology is particularly useful in locating missing persons, verifying identities in fraud cases, and confirming suspect information in criminal investigations.

Pattern Recognition & Predictive Behavior Analysis

Big data analytics allow investigators to identify unusual activity within financial records, online transactions, and communication histories. By detecting anomalies, private investigators can predict fraudulent activities and uncover hidden connections that might otherwise remain unnoticed.

Cybersecurity & Ethical Hacking

Penetration Testing for Corporate Security

Businesses frequently hire private investigators to test the strength of their cybersecurity defenses. Ethical hackers simulate cyberattacks to identify security weaknesses, helping organizations prevent costly data breaches and intellectual property theft.

Employee Monitoring & Fraud Detection

Internal fraud is a growing concern for businesses. Investigators use forensic accounting, network monitoring, and digital surveillance to detect unauthorized transactions, data leaks, and potential corporate espionage. By uncovering fraudulent activities, companies can take action before financial damage occurs.
