SIA CCTV Evidence Handling 1 — Questions and Answers
Question 1: What is the 'chain of custody' in relation to CCTV evidence?
- The physical chain used to secure the recording equipment
- A documented trail showing who has handled the evidence and when (Correct answer)
- The order in which cameras recorded an incident
- The custody process for arrested individuals
Correct answer: A documented trail showing who has handled the evidence and when
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?
- The native format of the recording system with the proprietary player (Correct answer)
- Any common video format like MP4
- Only photographs from the footage
- Audio-only recordings
Correct answer: The native format of the recording system with the proprietary player
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?
- Delete all non-essential footage
- Continue monitoring, alert the relevant authorities, and begin documenting the incident (Correct answer)
- Leave the control room to intervene
- Switch off the recording to save the footage
Correct answer: Continue monitoring, alert the relevant authorities, and begin documenting the incident
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?
- It makes the footage look more professional
- It provides a verifiable timeline that can corroborate or contradict witness statements (Correct answer)
- It is only needed for insurance claims
- It helps identify the camera model
Correct answer: It provides a verifiable timeline that can corroborate or contradict witness statements
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?
- Notes written weeks after an incident
- A record made at the time of or shortly after the incident (Correct answer)
- Notes shared on social media
- A pre-written template filled in later
Correct answer: A record made at the time of or shortly after the incident
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.
Question 6: If CCTV evidence is required for a court case, what must the operator be prepared to do?
- Delete the footage after copying
- Attend court to give evidence about how the footage was obtained and handled (Correct answer)
- Send the footage anonymously
- Only provide a verbal description of what was seen
Correct answer: Attend court to give evidence about how the footage was obtained and handled
CCTV operators may be required to attend court as witnesses to explain how the footage was captured, stored, and handled, confirming the chain of custody and authenticity.
