DIY Security Camera Installation: The Real South African Guide (With Photos)

🛠️ Tools You Actually Need (And What You Can Skip)

Here’s what I pack for every installation:

Essential Tools (R800-R1,200 total if buying new)

What You DON’T Need (Despite What Forums Say)

• Expensive cable pulling rods (coat hanger works)
• Professional crimping kit (R2,000+ overkill)
• Fusion splicer (that’s fiber, not ethernet)
• Oscilloscope (seriously, who suggested this?)

📦 Shopping List: Everything You Need

Based on a typical 4-camera home system:

Pro tip: Buy 10% extra cable and connectors. You WILL make mistakes.

📍 Camera Placement: Where Criminals Actually Enter

After analyzing 100+ break-in videos from SA properties, here’s where cameras must go:

Priority 1: Entry Points (80% of intrusions)

1. Front gate/driveway
   • Mount 3m high, angled down at 30°
   • Must see faces, not tops of heads
   • Cover gate motor (popular theft target)
2. Back/side doors
   • Most forgotten, most targeted
   • Include any servant quarters access
3. Main entrance
   • Doorbell height = useless (hoodie blocks face)
   • Mount 2.5-3m high instead

Priority 2: Vulnerable Areas

• Ground floor windows (especially hidden ones)
• Garage side door (always forgotten)
• Pool pump/equipment area (copper theft)
• Boundary walls near trees/poles

🔌 Step-by-Step Installation Process

Step 1: Plan Your Cable Routes (1 hour)

This is where most DIYers mess up. Measure twice, drill once:

1. Map the route from each camera to NVR
   • Shortest path isn’t always best
   • Avoid running parallel to electrical cables (interference)
   • Stay 30cm away from fluorescent lights
2. Check for obstacles
   • Use stud finder to avoid water pipes
   • Look for electrical conduits in walls
   • Plan around steel beams in roof
3. Calculate cable lengths
   • Add 2m extra per camera for connections
   • Maximum PoE distance: 90m (keep under 80m)

Step 2: Install Conduit (2-3 hours)

SA weather destroys exposed cables. Here’s what works:

1. Exterior runs: 20mm PVC conduit mandatory
   • UV-resistant grey type (not white)
   • Secure every 1m with saddle clamps
   • Use proper bends, not 90° elbows
2. Drilling through walls
   • 16mm hole for single cable
   • Angle down slightly (water runoff)
   • Seal with silicone after cable install
3. Roof/ceiling runs
   • Follow existing beams where possible
   • Keep away from hot water pipes
   • Use cable trays for multiple runs

Step 3: Pull Cables (2-3 hours)

The most frustrating part. Here’s how to make it easier:

1. Label EVERYTHING
   • Both ends: “CAM1-FRONT”, “CAM2-BACK”
   • Use permanent marker on tape
   • Trust me, you’ll thank yourself later
2. Pulling technique
   • Attach cable to fish tape with electrical tape
   • Create smooth “nose” – no sharp edges
   • Pull steadily, don’t yank
   • Have someone feed cable to prevent kinks
3. Common obstacles
   • Insulation: Use coat hanger to create path
   • Tight corners: Pull back 30cm, try again
   • Full conduits: Use cable lubricant (R45)

Step 4: Terminate Cables (1 hour)

Where most DIY installs fail. Follow this exactly:

Common crimping mistakes:

• Wires not fully inserted (connection fails intermittently)
• Wrong wire order (camera won’t power up)
• Jacket not inside connector (wires pull out)
• Over-crimping (damages connector)

Step 5: Mount Cameras (1-2 hours)

1. Test before mounting!
   • Connect to NVR temporarily
   • Check image quality and angle
   • Verify night vision activation
2. Mounting process
   • Mark holes with template (usually included)
   • Drill 6mm holes, 40mm deep
   • Insert wall plugs flush
   • Leave 5mm play for adjustment
3. Weatherproofing
   • Run cable loop below camera (drip loop)
   • Seal wall entry with silicone
   • Use junction box for connections

⚡ NVR Setup & Configuration

Initial Setup (30 minutes)

1. NVR placement
   • Locked cabinet/room (not visible)
   • Well ventilated area
   • UPS protected (load shedding)
2. First boot
   • Connect monitor and mouse
   • Set admin password (write it down!)
   • Set correct date/time
   • Configure network settings
3. Add cameras
   • PoE models: Auto-detect when connected
   • Assign meaningful names immediately
   • Set recording quality (Main Stream)

Critical Settings Most People Miss

• Motion detection zones
  • Exclude trees/bushes (false alarms)
  • Set different sensitivity day/night
  • Test with actual movement
• Recording schedule
  • Continuous for high-risk areas
  • Motion-only for low traffic
  • Higher quality during crime hours (10pm-6am)
• Network security
  • Change default ports
  • Disable P2P if not needed
  • Use strong passwords (not admin/12345)

🚫 Common DIY Mistakes (And How to Avoid Them)

Mistake 1: Buying the Wrong Cameras

• WiFi cameras for outdoor: Connection drops constantly
• Non-PoE cameras: Double installation work (power + data)
• 2MP in 2025: Can’t identify faces beyond 3m
• Fix: Stick to 4MP+ PoE cameras from known brands

Mistake 2: Cable Run Disasters

• Through roof without conduit: Rats feast on cables
• Parallel to power lines: Video interference
• No drip loops: Water runs into connections
• Fix: Plan routes properly, use conduit everywhere

Mistake 3: Poor Camera Positioning

• Too high: See tops of heads only
• Facing into sun: Blinded morning/evening
• Behind burglar bars: IR reflection ruins night vision
• Fix: Test positions before final mounting

Mistake 4: No Backup Power

• System dies during load shedding: Criminals know schedules
• Fix: Minimum 1200VA UPS for 4-camera system

🔧 Troubleshooting Guide

“No Video” on One Camera

1. Test cable with tester (usually the issue)
2. Check PoE power budget not exceeded
3. Try different NVR port
4. Re-terminate connectors

Intermittent Connection

• Bad crimp job (redo termination)
• Cable exceeds 90m
• Water in connections
• Loose connector

Poor Night Vision

• Spider webs (clean monthly)
• IR reflecting off nearby surface
• Camera behind glass/bars
• Dirty lens cover

💰 Real Cost Breakdown: DIY vs Professional

🎓 Skills You’ll Learn

Beyond saving money, you’ll gain valuable skills:

• Basic networking (IP addresses, ports)
• Cable termination (useful for home network)
• Power calculations for load shedding
• Troubleshooting methodology
• Understanding your security system fully

⚖️ When to Call a Professional

Be honest – some situations need experts:

• 3-story house: Safety risk not worth it
• Listed building: Special requirements
• Complex integration: Alarms, access control, automation
• No tools/skills: Buying all tools costs more than labor
• Warranty requirements: Insurance may require certified install
