SIA CCTV System Maintenance 1 — Questions and Answers
Question 1: How often should CCTV cameras and equipment be inspected as part of routine maintenance?
- Only when they break down
- Regularly, according to a planned maintenance schedule (Correct answer)
- Once a year
- Only after a major incident
Correct answer: Regularly, according to a planned maintenance schedule
CCTV systems should be inspected regularly according to a planned preventative maintenance schedule. This helps identify and resolve issues before they lead to system failures.
Question 2: What is the most common cause of poor image quality on outdoor CCTV cameras?
- Outdated software
- Dirty or obstructed lenses and camera housings (Correct answer)
- Too many cameras on the system
- Excessive lighting
Correct answer: Dirty or obstructed lenses and camera housings
Dirt, dust, cobwebs, and condensation on camera lenses and housings are the most common causes of poor outdoor image quality. Regular cleaning is essential.
Question 3: What should be checked when testing a CCTV recording system?
- Only the live view
- That footage is recording correctly, time stamps are accurate, and playback quality is acceptable (Correct answer)
- Only the external cameras
- Just the colour settings
Correct answer: That footage is recording correctly, time stamps are accurate, and playback quality is acceptable
A thorough recording system check should verify that footage is being recorded properly, time and date stamps are accurate, playback quality meets operational requirements, and storage capacity is adequate.
Question 4: What is the purpose of an Uninterruptible Power Supply (UPS) in a CCTV system?
- To improve image quality
- To provide backup power during mains power failures (Correct answer)
- To boost the internet connection
- To control camera movements
Correct answer: To provide backup power during mains power failures
A UPS provides temporary backup power during mains electricity failures, allowing the CCTV system to continue recording and giving operators time to safely shut down equipment if necessary.
Question 5: Why is it important to maintain accurate time synchronisation across all CCTV cameras?
- It makes the footage look professional
- Consistent time stamps are essential for evidence integrity and correlating events across multiple cameras (Correct answer)
- It reduces storage requirements
- It improves image quality
Correct answer: Consistent time stamps are essential for evidence integrity and correlating events across multiple cameras
Accurate time synchronisation ensures that footage from different cameras can be reliably correlated, and that time stamps are accurate for evidential purposes in court.
Question 6: What should an operator do if they notice a camera has stopped recording?
- Ignore it until the next maintenance visit
- Log the fault, report it to the appropriate person, and attempt basic troubleshooting if trained (Correct answer)
- Try to fix it themselves regardless of training
- Wait for someone else to notice
Correct answer: Log the fault, report it to the appropriate person, and attempt basic troubleshooting if trained
The operator should log the fault in the incident log, report it through the proper channels, and attempt basic troubleshooting (such as checking connections) only if they are trained to do so.
