CCTV & Alarm System Forensics
Reconstruct the sequence of events.
Preservation and examination of CCTV recordings, native exports and available alarm or monitoring logs. We assess recording continuity, clock differences and event sequences, correlating video with activation, arming, disarming and response records where available.
CCTV recordings and alarm or monitoring logs can show when people arrived and left, when a system was armed or disarmed, and the order in which events took place. They are also easily lost: many systems overwrite recordings automatically under their retention settings.
Where possible, we arrange preservation of the original recordings or native exports rather than relying on copies, screen recordings or compressed clips, and we document the system, its time settings and the export process.
We examine recording continuity and gaps, differences between system clocks and actual time, and the sequence of events across cameras. Where records are available, we correlate the video with alarm activation, arming, disarming and monitoring-centre response, producing an event timeline that can be followed and checked.
Questions this examination can help answer
- Is the recording complete, or are there gaps?
- Does the time shown on the footage reflect the actual time of events?
- Does the alarm log match what the cameras recorded?
- In what order did events happen across different cameras and systems?
What the evidence can and cannot establish
Image quality, camera position, recording settings and missing or overwritten footage limit what can be established. A phone recording of a CCTV screen is a poor substitute for the underlying recording.
Our examinations are independent and objective. We report material findings whether they support or challenge the position under examination. We explain what the digital evidence supports, the limitations that apply and what cannot be established.
Before you instruct us
What should I do with a device that may contain evidence?
Contact us promptly for advice specific to the device and its current state. Avoid unnecessary use, resets, updates, deletions and attempts to recover data yourself. Seek guidance before changing its power or network state, and record who has handled it. The appropriate preservation steps depend on the source and circumstances.
What does a forensic report include?
The report addresses the agreed questions and identifies the material examined, methods, significant findings, supporting references and limitations. It separates observations from technical interpretation. Timelines and exhibits may accompany the report where relevant. A discussion with your lawyer and court testimony can be arranged where required and agreed.
THE APPROACH
A traceable process.
From source to finding.
A defensible finding needs a traceable basis. We document the acquisition, tools, procedures and limitations so that the examination and its conclusions can be independently assessed.
- 01
Define
Agree the authority, questions, relevant sources and scope with you and your legal adviser before examination begins.
- 02
Preserve
Document receipt, handling and transfers. Preserve source material and use verified forensic copies or appropriate exports wherever practicable. Record acquisition methods and appropriate integrity checks, including cryptographic hashes where applicable.
- 03
Examine
Check material findings against their sources. Correlate records and timelines, test alternative explanations and document examination coverage.
- 04
Explain
Report findings objectively. Distinguish observations, interpretation and limitations, with references that allow the reasoning to be followed.
A keyword result or a device event needs context. Our conclusions reflect the available evidence and the limits of the examination.
