Quick Comparison

Feature Burglar Alarm CCTV
Primary Function Real-time intrusion alerts Visual surveillance
Detection Door/window sensors Camera recording
Deterrence Loud sirens Visible cameras
Response Instant alerts Delayed (review footage)
Evidence No visual proof Video evidence
Cost (typical) R3,000 - R10,000 R5,000 - R20,000

How They Work

Burglar Alarm Systems

Components:

  • Control panel
  • Door/window sensors
  • Motion detectors
  • Siren
  • Keypad
  • Optional: Armed response connection

How it works:

  1. Sensors detect entry/motion
  2. Control panel triggers alarm
  3. Loud siren activates
  4. Alert sent to owner/response company
  5. Armed response dispatched

Types:

  • Wired systems (R3,000 - R6,000)
  • Wireless systems (R5,000 - R10,000)
  • Hybrid systems (R6,000 - R12,000)

CCTV Systems

Components:

  • Cameras (indoor/outdoor)
  • DVR/NVR recorder
  • Hard drive storage
  • Power supplies
  • Cabling
  • Monitor (optional)

How it works:

  1. Cameras record continuously
  2. Video stored on DVR/NVR
  3. Motion alerts sent to phone (smart systems)
  4. Review footage after incidents
  5. Evidence for investigations

Types:

  • Analog systems (R3,000 - R8,000)
  • IP camera systems (R8,000 - R20,000)
  • Wireless systems (R5,000 - R15,000)

Detailed Comparison

Detection & Response

Burglar Alarm:

  • Immediate detection of intrusion
  • Instant siren and alert
  • Seconds to armed response dispatch
  • No visual verification

CCTV:

  • Records all activity
  • Motion detection alerts (smart systems)
  • Visual verification of threat
  • Evidence for investigation

Winner: Alarm for speed, CCTV for verification

Deterrence

Burglar Alarm:

  • Alarm company signage deters
  • Sirens scare intruders away
  • Less visible to criminals

CCTV:

  • Visible cameras deter
  • Criminals avoid being recorded
  • May encourage masks/evasion

Winner: Both effective, different approaches

Evidence Collection

Burglar Alarm:

  • No visual evidence
  • Log of events only
  • Limited for insurance claims

CCTV:

  • Video of incident
  • Face/vehicle identification
  • Strong for insurance/police

Winner: CCTV clearly

Cost Comparison

System Initial Cost Monthly Cost
Basic alarm R3,000 - R5,000 R0 (self-monitor)
Alarm + response R4,000 - R8,000 R200 - R500
Basic CCTV (4 cameras) R5,000 - R8,000 ~R100 electric
Smart CCTV (8 cameras) R10,000 - R20,000 ~R150 electric

Insurance Impact

Burglar Alarm:

  • Often required by insurers
  • Armed response connection may be mandatory
  • Premium discounts available

CCTV:

  • May reduce premiums
  • Helps with claim processing
  • Evidence speeds payouts

Winner: Alarm often required, CCTV helps claims

South African Context

Crime Statistics

  • 50.9% of households fear burglary (StatsSA)
  • Armed response crucial in high-crime areas
  • Evidence collection increasingly important

Load-Shedding Considerations

Burglar Alarm:

  • Battery backup (4-8 hours)
  • GSM communication unaffected
  • May need to re-arm after outage

CCTV:

  • UPS required for continuous recording
  • Some cameras have battery backup
  • Cloud storage protects footage

Best Approach: Combined System

Security experts recommend both:

How They Work Together

  1. Alarm detects intrusion
  2. CCTV captures footage
  3. Armed response gets visual verification
  4. Evidence preserved for police
  5. Insurance claims supported

Combined System Benefits

  • Immediate detection AND evidence
  • Visual verification reduces false alarms
  • Comprehensive protection
  • Better insurance position

Combined System Costs

Level Cost
Basic (alarm + 4 cameras) R8,000 - R12,000
Standard (smart alarm + 8 cameras) R15,000 - R25,000
Premium (full integration) R25,000 - R40,000
