Before commencing any installation, careful planning is crucial. This involves several key steps:
Determine your needs: Identify the areas you need to monitor, the type of cameras required (indoor, outdoor, dome, bullet, PTZ), and the desired recording resolution and storage capacity. Consider factors like lighting conditions, potential vandalism, and desired field of view.
Choose your equipment: Select cameras, a Digital Video Recorder (DVR) or Network Video Recorder (NVR), cables (coaxial or network cable), power supplies, mounting brackets, and any necessary accessories (e.g., power splitters, baluns).
Plan cable routing: Map out the most efficient and discreet routes for your cables, minimizing visible wiring and avoiding obstacles. Consider using conduit for protection and aesthetic purposes. Note the distances involved to ensure appropriate cable lengths.
Obtain necessary permissions: If installing cameras on shared property or in public areas, ensure you have the necessary permits and permissions.

Mount the bracket: Securely attach the mounting bracket to the chosen location using appropriate screws and anchors. Ensure the bracket is level and firmly attached.
Connect the cables: Carefully connect the power and video cables to the camera, ensuring proper polarity and secure connections. Use cable ties to keep cables organized and prevent damage.
Install the camera: Attach the camera to the bracket, ensuring it is securely fastened and aligned correctly. Adjust the camera's angle to optimize the field of view.
Test the camera: Connect the camera to the DVR/NVR and verify that the image is clear and focused. Adjust the camera settings as needed.

The DVR/NVR is the central hub of your CCTV system. Follow these steps:
Connect the cameras: Connect the video and power cables from each camera to the corresponding ports on the DVR/NVR. Refer to your DVR/NVR manual for detailed instructions.
Connect to power: Plug in the DVR/NVR power supply and ensure it is properly connected to a grounded outlet.
Network configuration: If using a network-based system (NVR), configure the network settings according to your network infrastructure. This usually involves assigning an IP address and configuring network protocols.
Monitor connection: Connect a monitor to the DVR/NVR to view the live camera feeds.
Record settings: Configure the recording settings, including recording schedules, motion detection sensitivity, and storage capacity.

Phase 4: Testing and Fine-tuning

After completing the installation, thoroughly test the entire system. Check for:
Clear image quality: Ensure all cameras provide clear and focused images in various lighting conditions.
Proper recording functionality: Verify that the DVR/NVR is recording footage as expected.
Network connectivity (if applicable): Ensure remote access and network connectivity are functioning correctly.
Motion detection accuracy: Adjust motion detection sensitivity to minimize false alarms.

Phase 5: Ongoing Maintenance

Regular maintenance is vital for optimal performance and longevity. This includes:
Regularly cleaning lenses: Keep camera lenses clean to maintain image clarity.
Checking cable connections: Inspect cables for damage and ensure secure connections.
Monitoring hard drive space: Ensure sufficient storage space for recordings.
Software updates: Update the DVR/NVR firmware to benefit from bug fixes and new features.
