SIA CCTV Evidence Handling 2

Question 1

What is the main risk of using digital enhancement on CCTV evidence?

Accepted Answer

It could be argued that the enhancement has altered or fabricated evidence

Answer

Digital enhancement can be challenged in court as potentially altering the original evidence. Any enhancement must be documented, the original preserved, and the process must be transparent and repeatable.

Question 2

What is the correct procedure for storing CCTV evidence that has been secured for an investigation?

Accepted Answer

Store it in a secure, access-controlled location with a documented chain of custody

Answer

Evidence must be stored in a secure, access-controlled location to prevent tampering or unauthorised access. Every access must be documented in the chain of custody log.

Question 3

What type of media is commonly used to export CCTV evidence for police?

Accepted Answer

A write-once disc (CD-R or DVD-R)

Answer

Write-once media such as CD-R or DVD-R is preferred because once data is written, it cannot be altered. This helps prove the evidence has not been tampered with.

Question 4

An operator is asked to produce a witness statement about CCTV footage. What should it contain?

Accepted Answer

Factual details of what they observed, their actions, the equipment used, and the evidence handling process

Answer

A witness statement should contain factual information: what the operator saw, what actions they took, the equipment and camera details, time stamps, and how the evidence was handled and secured.

Question 5

What could happen if the chain of custody for CCTV evidence is broken?

Accepted Answer

The evidence could be deemed inadmissible in court

Answer

If the chain of custody is broken, the defence can argue that the evidence may have been tampered with or contaminated, potentially making it inadmissible in court.
