CSC Surveillance & Monitoring Systems 2 — Questions and Answers
Question 1: What is the primary advantage of using IP-based cameras over analog CCTV cameras in a modern surveillance system?
- Lower initial installation cost
- Remote access and higher resolution imagery (Correct answer)
- Immunity to network-based attacks
- Simpler wiring requirements
Correct answer: Remote access and higher resolution imagery
IP cameras transmit digital video over a network, enabling remote access from any internet-connected device and offering significantly higher resolution than analog CCTV.
Question 2: A security consultant discovers that a client's PTZ camera can be accessed via a default manufacturer password. What is the FIRST corrective action?
- Disable the camera until a solution is found
- Change the default credentials immediately (Correct answer)
- Replace the camera with a newer model
- Block all inbound traffic to the camera's IP
Correct answer: Change the default credentials immediately
Changing default credentials is the immediate, least-disruptive fix that eliminates one of the most exploited vulnerabilities in networked cameras.
Question 3: Which lighting condition is BEST addressed by selecting cameras with Wide Dynamic Range (WDR) technology?
- Complete darkness in an interior space
- Scenes with simultaneous bright and shadowed areas (Correct answer)
- High-speed motion in a brightly lit exterior
- Low-contrast monochrome environments
Correct answer: Scenes with simultaneous bright and shadowed areas
WDR technology balances exposure across bright and dark regions within the same frame, such as a building entrance with bright outdoor light and a dark interior.
Question 4: In video surveillance, what does 'edge storage' refer to?
- Storing footage on central NVR servers
- Recording video directly on the camera using onboard SD cards (Correct answer)
- Backing up footage to an off-site cloud provider
- Encrypting video at the network perimeter
Correct answer: Recording video directly on the camera using onboard SD cards
Edge storage means video is recorded on storage media (such as SD cards) built into the camera itself, reducing dependency on continuous network connectivity.
Question 5: A consultant is designing a surveillance system for a parking structure with poor lighting. Which camera type is MOST appropriate?
- Day/night camera with IR illumination (Correct answer)
- Standard color box camera
- PTZ camera with optical zoom only
- Fisheye camera without IR
Correct answer: Day/night camera with IR illumination
Day/night cameras with integrated IR illuminators are specifically designed to capture usable footage in low-light or complete darkness without supplemental white-light fixtures.
Question 6: What is the purpose of a video management system (VMS) in a surveillance infrastructure?
- To physically secure camera housings against tampering
- To centrally manage, record, and review footage from multiple cameras (Correct answer)
- To increase wireless signal strength between cameras
- To generate synthetic video for system testing
Correct answer: To centrally manage, record, and review footage from multiple cameras
A VMS is software that integrates multiple cameras into one platform, enabling centralized control, recording schedules, playback, and alerts.
Question 7: Which standard governs the interoperability of IP-based security cameras and video management systems from different manufacturers?
- ISO 27001
- ONVIF (Correct answer)
- NIST SP 800-53
- H.265/HEVC
Correct answer: ONVIF
ONVIF (Open Network Video Interface Forum) is the industry standard that ensures interoperability between IP-based surveillance products from different vendors.
