Question 1

What is the 'chain of custody' in relation to CCTV evidence?

Accepted Answer

A documented trail showing who has handled the evidence and when

Answer

The chain of custody is a documented record of every person who has handled the evidence, when they handled it, and what they did with it. This ensures the evidence has not been tampered with.

Question 2

When exporting CCTV footage as evidence, what format is generally preferred by UK courts?

Accepted Answer

The native format of the recording system with the proprietary player

Answer

UK courts generally prefer footage in the native format of the recording system, along with the proprietary player software. This preserves the original quality and metadata, and demonstrates the footage has not been altered.

Question 3

What should a CCTV operator do immediately when they witness a crime on camera?

Accepted Answer

Continue monitoring, alert the relevant authorities, and begin documenting the incident

Answer

The operator should continue to monitor and record the incident, alert police or security as per their procedures, and begin documenting everything in the incident log.

Question 4

Why is it important to record the time and date stamp when exporting CCTV evidence?

Accepted Answer

It provides a verifiable timeline that can corroborate or contradict witness statements

Answer

Accurate time and date stamps are crucial as they provide a verifiable timeline of events that can corroborate or contradict witness accounts and other evidence.

Question 5

What is a 'contemporaneous note' in relation to CCTV evidence?

Accepted Answer

A record made at the time of or shortly after the incident

Answer

A contemporaneous note is a record made at the time of or very shortly after the event being described. Courts give greater weight to contemporaneous notes because memories are freshest at that time.
