Introduction
One of the most common questions we hear at Garrison Alarms is: “How many cameras do I actually need?”
The answer isn’t “as many as possible”—it’s about strategic placement and complete coverage of your property’s vulnerable areas. Too few cameras leave blind spots; too many waste money and storage.
In this guide, we’ll help you determine the ideal number of cameras for your Auckland home, walk through placement strategies, and explain how different property types affect your needs.
The Quick Answer
For most Auckland homes:
- Small apartments or units: 1–2 cameras
- Average 3-bedroom houses: 3–4 cameras
- Large homes or properties: 5–8 cameras
- Properties with multiple outbuildings: 8–12+ cameras
But the real answer depends on your specific layout, entry points, and security priorities. Let’s walk through how to calculate what’s right for you.
Understanding Your Coverage Requirements
Principle 1: Identify Vulnerable Entry Points
The first step isn’t deciding on camera count—it’s mapping where intruders could enter your property.
Primary entry points to always monitor:
- Front door
- Back door
- Garage entry
- Side gates
- Windows at ground level (if accessible)
- Any external stairs or fire escapes
Why this matters: 90% of burglars enter through doors or windows. Cameras at these points deter criminals and capture evidence.
Principle 2: Establish Perimeter Coverage
After entry points, consider monitoring your property's perimeter:
- Front boundary/fence line
- Side boundaries
- Back boundary
- Driveway
- Car parking area
Commercial properties need more comprehensive perimeter coverage due to higher theft risk and insurance requirements.
Principle 3: Identify High-Value Area
Most homes have a few high-value zones worthy of dedicated cameras:
- Main living areas (visible from exterior)
- Garage/workshop (tools and vehicles)
- Outdoor entertaining area
- Swimming pool or hot tub
Principle 4: Consider Night-Time Coverage
Auckland's winter brings early darkness. Night vision capability is essential:
- All cameras should have infrared/night vision capability
- Ensure adequate lighting or professional IR setup
- Budget 10–15% extra for quality night-vision cameras
CCTV Camera Calculation by Property Type
Small Apartment or Townhousely Home Smart Lock
Property profile: <100m², limited outdoor space, single entry
Recommended cameras: 1–2
Setup:
1. Front door camera (doorbell-style or turret)
- Records all visitors and entry activity
- Captures package deliveries
2. Optional: rear/courtyard camera if you have a back entrance or outdoor seating area
Rationale: Apartments typically have managed security, so basic entry coverage is sufficient. One quality camera often provides enough deterrent and evidence.
Cost: $1,500–$2,500 including installation
Average 3-Bedroom Auckland House
Property profile: Suburban property, ~700m², typical 4-6 entry points
Recommended cameras: 3–4
Optimal setup:
1. Front door camera (highest priority)
- Captures all front approach activity
- Must include doorstep area
2. Back door/patio camera
- Covers rear entry and outdoor entertaining area
- Typically second-most-common break-in point
3. Driveway/garage camera
- Monitors vehicles and garage entry
- Captures number plate activity
- Deters catalytic converter theft
4. Optional 4th: Side gate or corner camera
- Monitors alternate escape routes
- Covers blind spots
Rationale: This creates comprehensive coverage of primary entry points plus vehicle protection. The 4th camera is discretionary based on your property layout.
Cost: $3,500–$5,500 including installation
Large Auckland Property
Property profile: 1000m+, multiple structures, large grounds
Recommended cameras: 5–8
Comprehensive setup:
- Front entrance – perimeter coverage
- Back door/patio – rear exit coverage
- Garage/driveway – vehicle and tool security
- Side gate/boundary – perimeter access
- Pool area (if applicable) – entertainment space protection
- Rear corner/outbuilding – shed or workshop coverage
- Secondary driveway (if applicable)
- Alternate rear exit (if applicable)
Rationale: Larger properties have multiple vulnerable points and greater perimeter to protect. Strategic placement ensures complete coverage without excessive blind spots.
Coverage: Typically 360° perimeter coverage
Cost: $7,000–$12,000 including installation
Multi-Level or Complex Properties
Property profile: Townhouses, villas, steep sites
Recommended cameras: 6–10
Special considerations:
Rationale: Larger properties have multiple vulnerable points and greater perimeter to protect. Strategic placement ensures complete coverage without excessive blind spots.
- Multiple entry levels require staggered coverage
- Upper-level balconies need monitoring
- Different sightlines require careful placement
- May need pan-tilt-zoom (PTZ) cameras for flexibility
Consultation recommended: Properties with complex architecture benefit from professional site assessment.
Commercial Property Sizing
Small Retail Shop (150m²)
Recommended: 4–6 cameras
- Includes: Cash register area, entrances, storage room, stockroom
Office Building (300m²)
Recommended: 4–8 cameras
- Includes: Front entrance, hallways, parking lot, storage areas
- Note: Workplace camera policies must comply with NZ employment law
Warehouse (500m+)
Recommended: 8–16+ cameras
- Includes: All entry/exit points, perimeter, high-value storage areas
- Note: May require specialist positioning and thermal cameras for large spaces
Camera Placement Strategy: The Three-Zone Approach
Professional installers use a three-zone strategy:
Zone 1: Entry Point Cameras (MUST HAVE)
These cameras capture facial features and identify visitors/intruders.
- Placement: 1.5–2 metres high, 1–2 metres from door
- Field of view:90–120 degrees
- Distance capability: 2–3 metres in front of entry
- Number: One per main entry point
Zone 2: Perimeter Cameras (SHOULD HAVE)
These cameras establish boundary monitoring and deter approach.
- Placement: 1.5–2 metres high, 1–2 metres from door
- Field of view: 120–160 degrees
- Distance capability: 5–8 metres coverage
- Number: Typically 1–2 per property edge
Zone 3: Wide Coverage Cameras (NICE TO HAVE)
These cameras provide situational awareness and context.
- Placement: 3–4 metres high, overlooking large areas
- Field of view:140–160 degrees
- Distance capability: 10–15 metres coverage
- Number: One per distinctive area (driveway, patio, pool)
Application: A typical 4-camera Auckland home might use:
- 2 Zone 1 cameras (front + back doors)
- 1 Zone 2 camera (side boundary)
- 1 Zone 3 camera (driveway overview)
Common Camera Placement Mistakes
Mistake 1: Cameras Too High
Problem: Can’t see faces or identifying features Solution: Mount 1.5–2 metres high at entry points, lower than you think
Mistake 2: Pointing Directly at Sun
Problem: Washout and glare make footage unusable Solution: Angle slightly to avoid direct sun; position shade if possible
Mistake 3: Insufficient Night-Vision Setup
Problem: Footage is dark and useless at night Solution: Use infrared cameras or install supplementary lighting
Mistake 4: Too Many Cameras with Weak NVR
Problem: System can’t process all feeds effectively Solution: Match camera count to recording equipment specifications
Mistake 5: Overlooking Audio Privacy
Problem: Recording audio may breach NZ privacy law Solution: Check Privacy Act requirements; audio on private property is complex
Mistake 6: Placing Cameras Where They're Easily Disabled
Problem: Criminals obscure lens or cut cables Solution: Mount higher, out of easy reach; use wireless systems for vulnerability reduction

Special Circumstances Requiring More Cameras
Properties in High-Risk Areas
Auckland suburbs with higher burglary rates may warrant additional cameras:
- Additional perimeter cameras
- 360-degree pan-tilt-zoom (PTZ) camera for flexible monitoring
- Consider professional 24/7 monitoring integration
Properties with High-Value Items
- Valuable vehicles (garage needs dedicated camera)
- Tools or equipment storage (workshop monitoring)
- Outdoor valuables (pools, garden furniture)
- Budget: Additional 1–2 cameras, $1,500–$2,500
Properties Undergoing Renovation
- Site security during construction
- Monitoring equipment storage
- Access control to work areas
- Typically temporary: Rental systems available
Rental Properties
- More durable camera housing needed
- Monitoring common areas is essential
- Privacy compliance more complex
- Typical setup: 3–5 cameras, with privacy signage
The Role of Camera Resolution and Features
Camera count isn't the only variable—quality matters tremendously.
1080p vs. 4K Economics
1080p cameras:
- Cost: $400–$600 per camera
- Resolution: Adequate for 2–4 metre coverage
- Suitable for: Apartment entry, basic residential
4K cameras:
- Cost: $700–$1,200 per camera
- Resolution: Excellent facial recognition up to 5+ metres
- Suitable for: Most residential, commercial
Decision principle: Fewer 4K cameras often provide better security than more 1080p cameras.
Advanced Features Worth Considering
AI Person Detection
- Filters alerts to only human activity (not animals or leaves)
- Cost: Add $200–$500 per system
- Value: Reduces false alerts by 70–80%
Night Vision with Infrared
- Essential for Auckland's winter darkness
- Integrated in most modern cameras
- Cost: Included or add $100–$200 per camera
Wide Dynamic Range (WDR)
- Handles high-contrast scenes (sunlit driveway with shadowed entry)
- Cost: Usually included in mid-range+ cameras
- Value: Critical for entry point cameras
Frequently Asked Questions
Can I use my smartphone camera instead of CCTV?
No. Smartphone cameras have limited field of view, poor night vision, lack continuous recording capability, and inadequate storage. Professional CCTV is essential for security and evidence.
How far away can a camera identify someone?
High-quality 4K cameras can identify people at 5–10 metres. Standard cameras manage 2–3 metres. This is why placement is more important than camera count.
Should I use a mix of camera types?
Yes. Garrison Alarms typically recommends:
- High-quality entry-point cameras (identify faces)
- Standard perimeter cameras (deter approach)
- Optional PTZ cameras for large areas (provide flexibility)
Can I monitor multiple properties with one system?
Yes. Cloud-based systems allow multi-property monitoring through mobile apps. However, each property needs independent local recording for evidence preservation.
Do I need permission from neighbors to point cameras at their property?
NZ privacy law is complex. You can monitor your own property, but pointing cameras at neighbors’ houses or properties requires care. Discuss with Garrison Alarms before installation.
What storage capacity do I need?
This depends on camera count, resolution, and retention period:
- 4 cameras, 7-day retention: 1–2 TB
- 4 cameras, 30-day retention: 4–6 TB
- 8 cameras, 30-day retention: 8–12 TB
Is wireless better than wired?
Both have advantages:
- Wired: More reliable, no WiFi dependence, professional appearance
- Wireless: Easier installation, flexible placement, fewer cables
- Best practice: Most professionals recommend wired for critical entry points + wireless for flexibility
What if I want to add cameras later?
Expansion is straightforward and typically costs $500–$1,200 per additional camera (cheaper than initial installation). Plan for future scalability during initial setup.

Summary
The ideal number of CCTV cameras depends on your property’s size, entry points, and layout—not a one-size-fits-all number. Most Auckland homes need 3–4 cameras, while smaller properties may need just 1–2 and larger estates might require 6–8+.
Strategic placement at entry points, perimeters, and high-value areas is more important than camera count. One high-quality camera at the right angle beats three poorly-positioned cameras.
