1
Site Survey and Planning

Before installing any camera a thorough site survey is essential. This is the foundation of every 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 or 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 equipment ensures long term reliability and performance.

Camera Types:

DVR vs NVR:

• DVR (Digital Video Recorder) works with analog or HD-CVI cameras using a coaxial cable
• NVR (Network Video Recorder) works with IP cameras over a network cable
• Choose between a DVR and an NVR based on the type of cameras you have and your existing infrastructure

3
Installing Camera Mounting Brackets

Proper mounting is important for footage and to prevent damage to the cameras

• Mark the spot where you want to drill on the wall or ceiling at the planned camera position
• Drill holes using a 6mm or 8mm drill bit
• Insert wall plugs into the drilled holes
• Screw the mounting bracket firmly to the wall
• Make sure the bracket is level
• For outdoor cameras use weatherproof junction boxes where the cables enter the wall

4
Running and Concealing Cables

Cable management is critical for a clean installation

For Analog or HD Cameras (DVR):

• Use a cable with BNC connectors for video
• Run a power cable alongside the coaxial cable
• Or use a combo cable that has both coaxial and power in one

For IP Cameras (NVR):

• Use a network cable with RJ45 connectors
• A PoE switch can provide power to the IP cameras so you do not need separate power cables
• The maximum cable length is 100 meters per camera from the PoE switch

Cable Concealment Methods:

• Surface conduit is the most common method and easy to maintain
• Concealed wiring in walls is best for aesthetics but requires civil work
• Cable trays or raceways are ideal for offices and commercial spaces
• Drop ceiling routing is a clean way to install cables in office buildings

5
Connecting Cameras to DVR or NVR

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

• Terminate the coaxial cable with BNC connectors
• Connect the BNC cables to the video input ports on the DVR
• Connect the power cables to the power distribution box
• For NVR plug the network cables directly into the NVR ports or PoE switch ports
• Connect the DVR or NVR to a monitor for live view
• Connect the DVR or NVR to your internet router for remote viewing
• Insert a hard drive into the DVR or NVR

6
DVR or NVR Configuration

After physical connections configure the system through the DVR or NVR menu

• Set the date and time
• Format the hard drive
• Set the recording mode
• Configure motion detection zones
• Set the video resolution and frame rate
• Configure overwrite settings
• Set up user accounts and passwords
• Configure the network settings

7
Setting Up Remote Viewing on Mobile and PC

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

• Download the DVR or NVR manufacturer app
• The app will allow you to view live footage and playback recorded videos remotely

8
Camera Angle Adjustment And Focus

We need to make sure the cameras are pointing in the right direction. This will help us see everything we need to see.

• 🎯 Look at the feed on the monitor and adjust the camera direction.
• 🎯 Tilt and pan each camera to cover the area we want to see.
• 🎯 For cameras that can zoom adjust the zoom and focus ring physically.
• 🎯 Make sure we can see the entry and exit points clearly at face level.
• 🎯 Turn off the lights and test the night vision to see if its working properly.
• 🎯 Check for lens glare from glass windows or reflective surfaces.
• 🎯 Take a picture or make a diagram of the camera positions for future reference.

9
Testing And Final Inspection

We need to test everything to make sure its working correctly.

• ✅ Check that all cameras are showing a live feed with the correct labels.
• ✅ Make sure the recording is working. Play back a few minutes of footage.
• ✅ Test the motion detection alerts. Walk in front of each camera.
• ✅ Check that we can access the cameras remotely using the mobile app on WiFi and mobile data.
• ✅ Make sure all cable connections are secure and weatherproofed.
• ✅ Confirm that the date and time stamps are accurate on all channels.
• ✅ Test the playback search by date, time and channel.
• ✅ Give the client the login credentials, app setup and user training.
