1. What You Need Before You Start

A successful CCTV installation starts with the right equipment. Buying cheap, undersized kits leads to blurry footage, frequent failures, and wasted money. Here’s what a complete system requires:

Core Equipment Checklist

• CCTV Cameras — Choose between Analog (AHD/TVI) or IP cameras. For most Kenyan homes, 2MP–5MP AHD cameras offer the best balance of cost and image quality.
• DVR (Digital Video Recorder) for analog cameras, or NVR (Network Video Recorder) for IP cameras.
• Hard Drive (HDD) — 1TB handles approximately 15 days of continuous recording on 4 cameras at 1080p. 2TB is recommended for businesses.
• RG59 Siamese Cable (for analog) or Cat6 Cable (for IP cameras) — buy quality cable. Poor cable is the number-one cause of signal loss in Kenya’s hot climate.
• BNC Connectors & Crimping Tool (for analog), or RJ45 connectors (for IP).
• Power Supply Unit (PSU) — centralized 12V DC power distribution board is cleaner than individual adaptors.
• Monitor or TV — any HDMI/VGA display for initial configuration.
• Drill, wall anchors, and cable clips for mounting.

Pro tip from our AreaSpy installation team: Always buy cameras and the DVR/NVR from the same brand family (Hikvision, Dahua, or Uniview are our top recommendations in Kenya). Mixing brands causes compatibility issues especially with smart features like motion alerts and colour night vision.

2. How to Plan Camera Placement

Camera placement determines whether your system actually catches intruders — or just records empty walls. Most break-ins in Nairobi happen through gates, perimeter walls, back doors, and ground-floor windows. Plan your coverage around those entry points first.

Priority Coverage Zones

• Main gate and driveway entrance — use a wide-angle camera (2.8mm lens) positioned to capture faces and number plates.
• Front door and back door — a 3.6mm lens gives a focused corridor view.
• Perimeter corners — position cameras to cover two fence lines simultaneously by mounting at 90° corners.
• Parking area — a varifocal camera (2.7–13.5mm) lets you zoom in on vehicle registration plates.
• Interior (optional) — reception areas, server rooms, or cashier desks for businesses.

Mounting Height: The 2.5–3 Metre Rule

Mount cameras between 2.5 and 3 metres high. Too low and they’re easily tampered with or spray-painted. Too high (above 4m) and downward angle distorts facial recognition. Angle the camera slightly downward — approximately 15° to 20° — for the best field of view.

Avoid These Placement Errors

• Pointing cameras directly at bright light sources (sun, security lights) — causes lens flare and washed-out images.
• Placing cameras where rain will drip directly onto the lens — always install a small drip ledge above outdoor cameras.
• Overlooking blind spots at corners — walk your perimeter and physically look through each camera angle before drilling.

3. Cable Routing & Power Supply

Cable routing is where most amateur installations go wrong. Poor cable management leads to signal interference, weather damage, and difficult future maintenance.

Best Practices for Kenya Conditions

• Use conduit outdoors — Kenya’s UV radiation and occasional heavy rains degrade unprotected cables within 12–18 months. PVC conduit is inexpensive and significantly extends cable lifespan.
• Route cables through walls or ceiling spaces where possible — surface-mounted cables are vulnerable to tampering.
• Keep video cable away from power cables — run them at least 30cm apart to prevent electrical interference causing lines or noise on your footage.
• Label every cable at both ends — this saves enormous time during future troubleshooting.
• Leave a 30cm service loop at each camera point — allows adjustment without cutting and re-terminating cables.

Power Calculation

Standard AHD cameras draw approximately 300–500mA each at 12V DC. A 4-camera system needs at minimum a 3A power supply; an 8-camera system needs 5A–8A. Always size your PSU 30% above calculated load to account for surge current at startup.

4. DVR/NVR Setup & Configuration

Once cameras are mounted and cables are connected, configuring your recorder correctly ensures you actually capture usable footage when you need it.

Initial DVR/NVR Setup Steps

1. Connect the DVR/NVR to your monitor via HDMI or VGA.
2. Connect power and wait for the startup wizard — most modern Hikvision/Dahua units auto-detect connected cameras.
3. Format the hard drive — new HDDs must be initialised through the DVR menu before recording begins.
4. Set the correct date, time, and timezone (East Africa Time, UTC+3) — critical for footage to be legally useful.
5. Configure recording mode: choose “Continuous + Motion Detection” for most Kenyan residential setups. This records at low frame rate continuously, but switches to full quality when motion is detected — balancing storage with coverage.
6. Set the overwrite policy — enable “auto-overwrite oldest footage” so the system doesn’t fill up and stop recording.
7. Change the default admin password immediately — a critical security step many people skip.

Recording Resolution Recommendations

• Entrances and high-priority zones: 1080p (2MP) at 15fps minimum.
• General overview cameras: 720p at 10–15fps is sufficient and saves storage.
• Avoid setting everything to maximum resolution — it fills your HDD in days and gains nothing for most applications.

5. Setting Up Remote Viewing on Your Phone

Remote viewing lets you monitor your property from anywhere via Safaricom, Airtel, or Wi-Fi. This is one of the most valued features for Kenyan homeowners managing properties or businesses remotely.

Steps to Enable Remote Access

1. Connect the DVR/NVR to your router via Ethernet cable (Wi-Fi is unreliable for recorders — always use wired).
2. In the DVR network settings, note the device serial number — modern systems use cloud P2P (Hik-Connect, DMSS, or iVMS-4500) and don’t require port forwarding.
3. Download the manufacturer’s app: Hik-Connect (Hikvision), DMSS (Dahua), or XMEye (generic brands).
4. Create an account, then add your device by scanning the QR code from the DVR menu or entering the serial number manually.
5. Test live view on both Wi-Fi and mobile data (4G). If live view works on Wi-Fi only, check your router’s UPnP settings or contact your ISP about a static IP.

Data usage note: Live HD streaming uses approximately 1–3GB per hour. Enable sub-stream (low-resolution) view for remote monitoring on mobile data to reduce costs.

6. Common CCTV Installation Mistakes to Avoid

• Using indoor cameras outdoors — they fail within months. Always check the IP rating: IP66 minimum for outdoor use in Kenya.
• Skipping the HDD — some cheap kits ship without a hard drive. No HDD means no recording.
• Not testing night vision before final mounting — test infrared coverage at night before sealing cable entries.
• Weak or shared passwords — a common entry point for DVR hacking. Use a unique 12-character password.
• No surge protection — Kenya’s power supply has frequent surges. A UPS or surge protector at the DVR significantly extends equipment life.

7. DIY vs Professional CCTV Installation in Kenya

For most Nairobi homes and businesses, professional installation pays for itself through better camera placement, neater cabling, and avoiding costly re-dos. Contact our AreaSpy team for a free site assessment across Nairobi and its environs.
