Installing CCTV cameras sounds simple until you start thinking about where each camera should go.
Should it be high or low?
Which direction should it face?
What happens when sunlight hits the lens?
And which cables should you use? These details can affect how clearly your cameras capture people, vehicles, entrances, and other important areas. A good installation starts with planning rather than simply mounting cameras wherever they seem convenient.
Here’s what to consider when planning CCTV installation for your property.
Why Does CCTV Installation Quality Matter?
A good camera cannot make up for poor installation. If the camera is positioned too high, faces the wrong direction, or has insufficient lighting, the footage may not be as useful as expected.
During CCTV camera installation, factors such as camera placement, viewing angle, lighting, and cable routing should all be considered. Taking time to plan each part of the installation can help you get more reliable coverage from your CCTV setup.
What Is the Right Height for a CCTV Camera?
There is no single height that works for every camera. The right position depends on what you want the camera to capture.
For entrances and other areas where identifying people matters, the camera should provide a clear view of faces. Cameras installed too high can mainly capture the tops of people's heads. Higher positions can still work for wider area monitoring.

How Should You Set the Camera Angle?
Besides height, the camera angle is also very important.
A camera tilted too far downward might miss important facial details. On the other hand, pointing a camera directly at a bright window can cause glare or make the person appear as a dark silhouette.
Before fixing a camera permanently, check its live view.
Look at the areas that matter most and make sure doors, sidewalks, driveways, and other key spaces are clearly visible. Even a slight movement can make a big difference to the camera's field of view.

How Does Lighting Affect CCTV Footage?
Lighting can change the quality of CCTV footage considerably. Strong sunlight, dark corners, and uneven lighting can make it difficult for a camera to capture useful details.
Think about how lighting changes throughout the day. An entrance that looks fine in the afternoon may become difficult to monitor when the sun moves behind the camera or shines directly toward the lens.

Always get cameras that can work in all types of light. Cameras that give great images during the day don't always show anything useful at night... Fuzzy, blurry, grainy shots that can't help the cops identify the face clearly are useless." Dr. Steve Albrecht, Security Consultant & Threat Assessment Expert |
What Happens When a Camera Faces the Sun?
A camera that is pointed to a strongly lit window or entry would have difficulties with the level of brightness. People in front of such a bright background may be too underexposed.
And, their details are hard to recognize.
Bearing this in mind, one is advised to position surveillance cameras with care, taking into account the natural sources of light.
On top of that, one can also install cameras that can cope with such scenes.
Where the whole picture consists of very bright and dark regions, i. e., cameras with wide dynamic range features.
Which CCTV Lens Should You Choose?
The lens determines how wide the camera can see and how much detail it can capture at different distances. A wide-angle lens can cover a larger nearby area, while a narrower lens can focus more closely on a specific distant location.
Choosing the lens based on the actual viewing distance is important. Simply choosing the widest possible view does not always provide the detail you need.

How Important Is Night Lighting?
Night-time monitoring needs extra attention, especially as CCTV use continues to grow in Singapore. The country plans to expand its national CCTV network from around 90,000 cameras to 180,000 by 2030 to support public safety.
For homes, the same principle applies on a smaller scale. Some cameras use infrared to capture footage when visible light is limited. Still, lighting around entrances, driveways, and pathways can improve visibility. Check both daytime and night-time conditions before finalizing camera placement.
What Type of Cabling Should You Use?
IP CCTV cameras need reliable network connections, making cable selection an important part of the installation. Cat6 cabling can be suitable for many network camera installations and can support high-speed data transmission.
The cable should also be appropriate for its environment. Outdoor runs may need additional protection from moisture, sunlight, and physical damage. Good cable planning can reduce connection problems and make maintenance easier later.
Why Does Cable Routing Matter?
CCTV cables should not simply be left exposed or loosely arranged. Outdoor cables may be affected by rain, sunlight, and temperature changes, while indoor cables can become difficult to trace when they are poorly organized.
Using suitable conduits, cable trays, and protective fittings can help keep the installation neat. Labeling cables can also make it easier to identify individual cameras if troubleshooting is required later.

How Can You Reduce CCTV Blind Spots?
Every camera has a field of view, so placing one camera does not automatically mean every part of the property is covered.
Walk around the property and identify areas that need monitoring. Pay particular attention to entrances, exits, corners, side passages, driveways, and other locations where someone could move outside the camera's view.

What Should You Check Before Installation?
A simple site survey can help you avoid many common problems. Start by marking the areas you want to monitor and then consider camera height, viewing angle, lighting, lens requirements, power, and cable routes.
You should also think about where the recording equipment will be placed. Planning these details beforehand makes it easier to decide how many cameras are actually needed and where each one should be installed.
What About the NVR and Recording Equipment?
For IP CCTV systems, an NVR can be used to record video from connected cameras. Its location should be secure while still allowing convenient access for maintenance.
Storage requirements also depend on factors such as the number of cameras, video resolution, recording schedule, and how long you want to retain footage. These requirements should be considered before choosing the recording equipment.
Should You Consider Backup Power?
CCTV cameras and recording equipment depend on electricity, so a power interruption can affect surveillance. A backup power solution can help keep the system running during outages.
The amount of backup required depends on the number of cameras and other connected equipment. If continuous monitoring is important for your property, power backup should be included in the installation plan rather than added later.

FAQs
What is the best height for a CCTV camera?
The best height depends on the purpose and location of the camera. Entrance cameras should provide a useful view of approaching people, while cameras used for wider outdoor monitoring may be positioned higher.
Does CCTV need good lighting?
Good lighting can improve the quality of CCTV footage. Cameras may have infrared or low-light capabilities, but lighting conditions should still be considered when choosing camera positions.
Is Cat6 suitable for CCTV cameras?
Cat6 can be suitable for many IP CCTV installations. The appropriate cable depends on the camera, network setup, installation distance, and environmental conditions.
How can I avoid CCTV blind spots?
Start with a site survey and identify important entrances, exits, corners, pathways, and other areas. Check the camera's field of view before permanently fixing it and use additional cameras where necessary.
Should CCTV and home networking be planned together?
For IP cameras, it makes sense to consider CCTV and networking together. Cameras depend on reliable network connections, suitable cabling, and recording equipment, so planning these requirements together can make the installation more organized.
