Best CCTV System for Offices in Australia
Office Buying Guide
Quick answer
A small office may only need 4 to 6 cameras. A typical office often lands around 6 to 12. A larger multi-level office can move into 12 to 24 or more. The key zones are usually reception, main entry, staff entry, corridors, comms or server rooms, car parks and after-hours access points, not blanket desk-by-desk monitoring.
Recommendation Table
| Site type | Typical camera count | Recommended system | Notes |
|---|---|---|---|
| Small office suite | 4 to 6 cameras | 8 channel PoE NVR | Front entry, reception, rear door and one restricted area often matter most. |
| Professional services office | 6 to 8 cameras | 8 or 16 channel NVR | Reception, waiting area, secure rooms and after-hours entry are common priorities. |
| Multi-room office | 8 to 12 cameras | 16 channel NVR | Corridors, staff entry and comms rooms add meaningful extra zones. |
| Multi-level office | 12 to 24 cameras | 16 or 32 channel NVR | Lift lobby, car park and several restricted entries often need separate treatment. |
| Office with showroom or warehouse | 10 to 16 cameras | 16 channel recorder path | Front-of-house and rear operational spaces should not be treated as one scene. |
4 vs 8 vs 16 Camera Office CCTV Systems
4 cameras
Enough for a small suite with one entry, reception and one rear or secure area. It becomes tight once parking, staff doors or several rooms matter.
8 cameras
Often the practical office starting point. It gives cleaner coverage of entry, desk, staff path, rear door, secure room and some shared circulation.
16 cameras
Better once the office has multiple floors, comms or records rooms, parking, several controlled doors or mixed office and operational space.
Coverage Zones That Matter
| Area | Recommended camera type | What to capture | Notes |
|---|---|---|---|
| Reception | Turret or dome | Visitor interaction and desk incidents | Usually needs a more stable view than the external entry camera. |
| Main entry | Fixed or varifocal | Arrival and face view | Often best paired with reception, not replaced by it. |
| Staff entry | Fixed or low-light camera | After-hours access | Commonly more important than buyers first expect. |
| Corridors | Turret or dome | Movement between key zones | Useful when tied to restricted rooms or access control. |
| Server or comms room | Fixed camera | Access line | Often better on the door line than deep inside the room. |
| Storeroom | Fixed camera | Controlled access and asset movement | Useful on selected offices. |
| Car park | Bullet or varifocal | Vehicle and person movement | Lighting and low-light performance matter here. |
| Lift lobby or fire exit | Fixed camera | Common-property movement | Important on larger office buildings. |
Camera Type Recommendations
- Turret or dome cameras: ideal for reception, corridors and internal shared areas.
- Varifocal cameras: useful at entries, car parks and wider waiting areas.
- Bullet cameras: practical on external approaches, rear doors and after-hours paths.
- Intercom and access-control crossover: often worth considering at reception or staff-only doors.
NVR and Recorder Planning
| Camera count needed | Recommended recorder | Why |
|---|---|---|
| 1 to 4 cameras | 8 channel NVR | Leaves room for another secure room or external view later. |
| 5 to 8 cameras | 8 or 16 channel NVR | 16 channels is safer where parking, several doors or more secure rooms exist. |
| 9 to 16 cameras | 16 channel NVR | Common office size once the site becomes more structured. |
| More than 16 cameras | 32 channel path | Better for multi-level offices or mixed-use commercial spaces. |
Storage and Retention
Office footage is often reviewed for entry disputes, safety incidents, contractor access, after-hours events and restricted-room questions. Storage depends on resolution, codec, frame rate and recording style.
| System size | Recording approach | Storage planning note |
|---|---|---|
| 4 to 6 cameras | Usually continuous on key entries | Still large enough to need deliberate HDD planning. |
| 6 to 12 cameras | Often continuous plus selected event logic | Car parks and after-hours paths usually increase storage use. |
| 12 to 24+ cameras | Mixed continuous and event recording | Needs stronger retention assumptions and user permissions. |
PoE, Network and Cabling
Wired PoE is usually the safer office path. Respect the 100m Ethernet limit, keep the recorder and switch path in a secure cabinet, and consider UPS backup where entry review or after-hours access matters. Avoid treating Wi-Fi cameras as the default commercial answer where proper cabling is practical.
Recommended System Paths
Entry / small site
Typical path: 4 to 6 cameras on an 8-channel NVR.
Best fit: HiLook or value-led business systems where the office is simple.
Standard / recommended site
Typical path: 6 to 12 cameras on a 16-channel NVR.
Best fit: Hikvision, Dahua or Uniview where secure rooms and stronger commercial depth matter.
Larger / higher-risk site
Typical path: 12 to 24 cameras with broader PoE planning.
Add-ons: access control, intercoms, UPS and stronger user permissions.

IP Cameras
Browse indoor and outdoor cameras for office entries and shared areas.
NVRs
Choose recorder size around office growth and retention.
PoE Switches
Useful on larger or multi-area office layouts.
Access Control
Useful for staff-only doors, server rooms and after-hours access.
Intercoms
Helpful where reception, visitor or after-hours door management matters.
Common Mistakes
- Watching desks instead of the real security zones.
- Skipping the server or comms room access line.
- No secure NVR or switch location.
- No notice or staff policy around footage access.
- Ignoring car parks or after-hours staff entries.
- Buying an NVR with no spare channels.
Compliance, Privacy and Governance Note
Office CCTV may capture staff, contractors and visitors. Employers and site managers should think about signage, purpose, footage access, retention and workplace expectations. Avoid intrusive monitoring of private or low-value desk scenes unless there is a genuine reason. This page is general buying guidance, not legal advice.

Office CCTV FAQs
What is the best CCTV system for an office?
For many offices, the best answer is a wired PoE IP CCTV system covering reception, main entry, staff entry, key corridors and restricted rooms, backed by a correctly sized NVR and sensible user permissions.
How many cameras does an office need?
A small office may only need 4 to 6 cameras. A typical office often lands around 6 to 12. Larger multi-level offices can move into 12 to 24 or more.
Should offices use dome or turret cameras?
Either can work. Turrets and domes usually suit internal areas, while bullets or varifocals often make more sense outside or across wider car-park views.
Can CCTV record staff desks?
Offices should be careful not to treat desk-by-desk coverage as a default. Entries, reception and restricted rooms usually matter more.
What NVR size does an office need?
Small offices can start around 8 channels, many standard offices suit 16-channel planning, and broader multi-level sites may need 16 to 32 channels.
Should office CCTV link with access control?
Often yes. Secure doors, visitor management and CCTV review usually work better when they are planned together.
How long should office CCTV footage be kept?
Retention should match the real review window for incidents, access disputes and after-hours events rather than a random number.
Do offices need signage?
Offices should think about notice, signage and permissions because the system captures staff, contractors and visitors.
Are Wi-Fi cameras suitable for offices?
They can suit some edge cases, but a wired PoE path is usually the better commercial answer where reliability matters.
Can office CCTV integrate with intercoms?
Yes. On some offices, reception entry, visitor doors and after-hours access work better when CCTV is planned alongside intercoms.
