Direct Answer

CCTV Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT) and commissioning provide a structured verification process to confirm that CCTV equipment and the installed integrated system comply with the approved design, specifications, functional requirements and agreed test procedures.

1. Engineering Overview

CCTV Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT) and commissioning provide a structured verification process to confirm that CCTV equipment and the installed integrated system comply with the approved design, specifications, functional requirements and agreed test procedures.

2. FAT–SAT–Commissioning Flow

Approved Design & Documentation → Equipment / Configuration Verification → FAT → Delivery & Installation → Pre-Commissioning → Point / Device Testing → Network Testing → Recording & VMS Testing → Functional Integration → SAT → Defect Closure → Final Acceptance → Handover

3. FAT Objective

FAT verifies equipment, software, configuration and defined functions before dispatch or site completion. The scope should be based on the approved FAT procedure, technical specification, approved drawings and agreed inspection requirements.

4. FAT Documentation

FAT documentation may include approved datasheets, equipment schedules, test procedures, camera schedules, network architecture, storage calculations, VMS configuration, test records and applicable manufacturer documentation.

5. Camera FAT

Where applicable, camera FAT should verify model, resolution, lens, imaging functions, environmental characteristics, communication interface and other specified features. The exact test scope should follow the approved FAT procedure.

6. NVR / VMS FAT

NVR / VMS FAT may verify channel capacity, recording functions, storage configuration, user permissions, live viewing, playback, export, alarms, PTZ functions and approved integrations.

7. Network Equipment FAT

Network equipment FAT may verify switch model, port capacity, PoE capability, uplink interfaces, configuration, VLAN functions and other approved network parameters.

8. FAT Witness & Records

FAT may be witnessed by the client, consultant or authorised representative where specified. All test results, observations, deviations and corrective actions should be recorded and signed by the relevant parties.

9. Site Pre-Commissioning

Before SAT, site readiness should be verified, including camera installation, cabling, network availability, power supply, equipment installation, recording infrastructure, workstation availability and approved system configuration.

10. Camera Installation Verification

Each camera should be checked for correct location, model, mounting height, orientation, lens, focus, field of view, environmental protection, cable termination and network connectivity.

11. Network Commissioning

CCTV network commissioning should verify IP addressing, PoE, switch connectivity, fibre links, uplinks, VLANs, routing / firewall communication and network stability according to the approved architecture.

12. NVR / Recording Commissioning

Recording commissioning should verify camera registration, recording profiles, recording schedule, storage availability, retention configuration, playback, export and recording failure indications.

13. VMS Commissioning

VMS commissioning should verify live viewing, camera registration, user permissions, graphics / layouts, playback, alarms, events, PTZ control, analytics and approved integration functions.

14. Image Quality Testing

Camera image quality should be checked under representative operating conditions. Verification may include resolution, focus, field of view, lighting, WDR, IR / low-light performance and target visibility as applicable.

15. PTZ Testing

PTZ cameras should be tested for pan, tilt, optical zoom, focus, presets, tours and authorised operator control. Limits and programmed functions should be verified against the approved configuration.

16. Alarm & Event Testing

Alarm and event testing should verify event generation, annunciation, priority, acknowledgement, logging, recording linkage and return-to-normal behaviour where applicable.

17. Analytics Testing

Where video analytics are included, each approved analytic function should be tested using representative scenarios. Analytics results should be assessed against the approved application and configuration.

18. Storage & Retention Testing

Testing should verify recording storage, configured retention, automatic overwrite behaviour, storage health, RAID / redundancy where applicable and playback across the required recording period.

19. Integration Testing

CCTV interfaces with access control, IBMS, intrusion detection or other approved systems should be tested against the interface matrix. Each interface should be verified for the defined status, alarm, control or event exchange.

20. User Acceptance / SAT

SAT should demonstrate that the installed CCTV system operates as an integrated solution under site conditions. Test results should be documented and compared with the approved acceptance criteria.

21. Failure & Recovery Testing

Where required, controlled tests should verify camera communication loss, switch failure, network interruption, recording failure, power interruption and redundancy / recovery functions. Testing should not compromise live safety or security operations.

22. Defect & Punch List

All defects identified during FAT, commissioning or SAT should be recorded in a controlled punch list with responsible party, corrective action, target closure and retest status.

23. Retesting & Closure

Corrective actions should be followed by retesting of the affected function. SAT / commissioning items should be considered closed only after the required functionality has been demonstrated and documented.

24. Handover Requirements

Handover should include approved as-built drawings, camera schedule, IP address schedule, network topology, NVR / VMS configuration, storage and retention information, test records, defect closure records, software / configuration backups and O&M documentation.

25. Maintenance Baseline

Commissioning results should establish the baseline condition for preventive maintenance. Camera image quality, storage health, network status, VMS operation and alarm performance should be recorded as applicable.

26. Change Control

Any change to approved camera models, locations, network architecture, recording parameters, VMS configuration, analytics or integrations identified during commissioning should be reviewed and documented through the approved change-control process.

27. Documentation

CCTV FAT, SAT and commissioning documentation should include, as applicable:

• Approved test procedures
• FAT records
• SAT records
• Camera test sheets
• Network test records
• NVR / VMS test records
• Storage / retention verification
• Alarm and event test records
• Analytics test records
• Integration test records
• Punch list and closure records
• Final acceptance records
• As-built documentation
• O&M manual

28. Engineering Objective

The engineering objective is:

Verify Equipment → Confirm Installation → Test Network & Devices → Validate Recording & VMS → Verify Alarms, Analytics & Integration → Conduct SAT → Close Defects → Obtain Acceptance → Establish Documented & Maintainable CCTV System

Frequently Asked Questions

What is the difference between FAT and SAT?

FAT checks equipment, software, configuration and defined functions before dispatch or site completion; SAT demonstrates the installed system under site conditions.

What happens to defects found during testing?

Record them in a controlled punch list, assign responsibility and corrective action, then retest affected functions and document closure.

What should handover include?

As-built drawings, schedules, network and NVR/VMS details, storage/retention information, test and defect-closure records, backups and O&M documentation.
