1
Site Survey & Planning

Before installing any camera, a thorough site survey is essential. This is the foundation of every successful CCTV project.

• ✅ Identify vulnerable areas — entrances, exits, parking, storage rooms, reception
• ✅ Assess lighting conditions — determine if night vision or IR cameras are needed
• ✅ Count camera positions — plan optimal angles to eliminate blind spots
• ✅ Plan cable routes — shortest, safest path from cameras to DVR/NVR location
• ✅ Choose camera types — dome, bullet, PTZ, or fisheye based on requirements
• ✅ Power source planning — PoE switches or individual power adapters per camera

2
Choosing the Right Equipment

Selecting the correct equipment ensures long-term reliability and performance.

📷 Camera Types:

📦 DVR vs NVR:

• DVR (Digital Video Recorder) — works with analog/HD-CVI cameras via coaxial cable
• NVR (Network Video Recorder) — works with IP cameras over network cable (Cat6)
• Choose based on your existing infrastructure and camera type

3
Installing Camera Mounting Brackets

Proper mounting ensures stable footage and prevents damage to the cameras.

• 🔧 Mark drill points on wall/ceiling at the planned camera position
• 🔧 Drill holes using a 6mm or 8mm drill bit (RCC walls need hammer drill)
• 🔧 Insert wall plugs (rawl plugs) into drilled holes
• 🔧 Screw the mounting bracket firmly to the wall
• 🔧 Ensure bracket is level — use a spirit level tool
• 🔧 For outdoor cameras, use weatherproof junction boxes where cables enter the wall

4
Running & Concealing Cables

Cable management is critical for a professional, clean, and long-lasting installation.

For Analog/HD Cameras (DVR):

• Use RG59 coaxial cable with BNC connectors for video
• Run 2-core power cable (12V DC) alongside the coaxial cable
• Or use a Siamese cable (combo coaxial + power in one)

For IP Cameras (NVR):

• Use Cat6 UTP/FTP cable with RJ45 connectors
• PoE switch eliminates need for separate power cables
• Maximum cable run: 100 meters per camera from PoE switch

Cable Concealment Methods:

• 🏠 Surface conduit (PVC pipe) — most common, easy maintenance
• 🏠 Concealed wiring in walls — best aesthetics, requires civil work
• 🏠 Cable trays/raceways — ideal for offices and commercial spaces
• 🏠 Drop ceiling routing — clean installation in office buildings

5
Connecting Cameras to DVR / NVR

This is the core wiring stage where each camera gets connected to the recording unit.

• 🔌 Terminate BNC connectors on coaxial cable (crimp or twist-on type)
• 🔌 Connect BNC cables to the video input ports on DVR (Channel 1, 2, 3…)
• 🔌 Connect power cables to the 12V DC power distribution box
• 🔌 For NVR: plug Cat6 cables directly into NVR ports or PoE switch ports
• 🔌 Connect DVR/NVR to a monitor via HDMI or VGA for live view
• 🔌 Connect DVR/NVR to your internet router for remote viewing
• 🔌 Insert Hard Disk Drive (HDD) into DVR/NVR — 1TB to 4TB recommended

6
DVR / NVR Configuration

After physical connections, configure the system through the DVR/NVR menu.

• ⚙️ Set date and time — critical for accurate recording timestamps
• ⚙️ Format HDD — initialize the hard drive from DVR settings menu
• ⚙️ Set recording mode — Continuous, Motion Detection, or Schedule-based
• ⚙️ Configure motion detection zones — define areas to trigger recording/alerts
• ⚙️ Set video resolution & frame rate — 1080p @ 15fps balances quality and storage
• ⚙️ Configure overwrite settings — auto-overwrite oldest footage when HDD is full
• ⚙️ Set up user accounts & passwords — admin and viewer roles
• ⚙️ Network configuration — assign static IP for remote access

7
Setting Up Remote Viewing (Mobile & PC)

One of the biggest advantages of modern CCTV systems is remote monitoring from anywhere.

• 📱 Download the DVR/NVR manufacturer app (e.g., iVMS-4200, XMEye, Hik-Connect, DMSS)
• 📱 On DVR/NVR: Enable P2P (Peer-to-Peer) cloud access in network settings
• 📱 Scan the QR code from the DVR menu using the mobile app
• 📱 For PC access: use CMS (Central Management Software) provided by manufacturer
• 📱 For advanced users: configure Port Forwarding on your router (RTSP port 554, HTTP port 80)
• 📱 Set up DDNS (Dynamic DNS) for stable remote access without static IP
• 📱 Enable push notifications for motion detection alerts on your phone

8
Camera Angle Adjustment & Focus

Fine-tuning camera angles ensures maximum coverage with no blind spots.

• 🎯 View live feed on monitor while adjusting camera direction
• 🎯 Tilt and pan each camera to cover the intended area
• 🎯 For varifocal cameras: adjust zoom and focus ring physically
• 🎯 Ensure entry/exit points are captured at face level (capture face, not top of head)
• 🎯 Test night vision by turning off lights — verify IR LED illumination range
• 🎯 Check for lens glare from glass windows or reflective surfaces
• 🎯 Document camera positions with a diagram for future reference

9
Testing & Final Inspection

A thorough test ensures everything works perfectly before handover.

• ✅ Verify all cameras show live feed with correct labels
• ✅ Check recording is happening — play back a few minutes of footage
• ✅ Test motion detection alerts — walk in front of each camera
• ✅ Verify remote mobile app access works on WiFi and mobile data
• ✅ Check all cable connections are firm and weatherproofed (outdoor cameras)
• ✅ Confirm date/time stamps are accurate on all channels
• ✅ Test playback search by date/time/channel
• ✅ Provide client with login credentials, app setup, and user training

10
Post-Installation Support & AMC

Professional CCTV installation doesn’t end at handover. Ongoing support keeps your system running optimally.

• 🛡️ Annual Maintenance Contract (AMC) — regular checkup visits
• 🛡️ HDD health monitoring — prevent data loss with timely replacements
• 🛡️ Firmware updates — keep DVR/NVR and cameras up to date
