CCTV Placement Guide: How to Eliminate Blind Spots Around North Wales Homes and Businesses

Part 5 of the 14-day security series

Welcome to Part 5 of our 14-day series for homeowners, shops, farms, offices and industrial premises across Conwy, Denbighshire and North Wales.

Effective CCTV installation starts with careful planning. A camera placed in the wrong position can leave a blind spot, capture poor-quality footage or create unnecessary privacy concerns.

Use this guide to plan CCTV placement around your property.

Start with a CCTV survey

Walk around the site before choosing camera positions.

Identify:

Consider how people and vehicles move through the site. Focus on areas where someone must pass, enter, leave or approach valuable property.

A professional CCTV survey should map these areas and identify possible obstructions. Trees, signs, rooflines, vehicles and outbuildings can all affect coverage.

Dragon provides professional CCTV surveys for domestic and commercial premises. Our team assesses the layout, lighting, risks and operational requirements before recommending a system.

Cover every entrance and exit

Entrances and exits should be the first priority.

For homes, consider:

For businesses, include:

Position cameras so they capture faces as people approach. Avoid pointing a camera directly down from a high roofline. This often records the top of a person’s head rather than useful facial detail.

A camera mounted slightly above head height and angled down can provide a better view. External cameras are commonly positioned around 2.5 to 3 metres high, depending on the property and the risk of tampering.

Entrances with bright windows or exterior sunlight may need additional adjustment. Wide Dynamic Range can help balance dark and bright areas, but the camera still needs to face the correct direction.

Protect side access and hidden routes

Side passages are common blind spots.

They may connect the front of a property to:

Do not assume that one front-facing camera will cover a side route. It may not capture movement behind a wall, gate or corner.

Use a dedicated camera where necessary. Position it to view the full length of the route. If the passage is narrow, a tighter field of view may provide better detail than a very wide camera.

Avoid placing the camera so that a gate, wall or overhanging roof blocks the lower part of the image. Test the view from the approach route, not just from the camera position.

For farms and rural premises, review access roads, vehicle gates and paths between buildings. Remote sites often have fewer people nearby to notice suspicious activity. Good camera placement can provide an early warning and useful evidence.

Plan yards, car parks and loading areas

Large areas need a different approach from doorways.

A wide-angle camera can provide an overview of:

However, one wide camera may not provide enough detail for identification. Use additional cameras where you need to identify faces, vehicles, number plates or activity around a particular asset.

For a car park, consider separate coverage for:

  1. The vehicle entrance and exit.
  2. The general parking area.
  3. Pedestrian routes to the building.
  4. Areas where vehicles or equipment are vulnerable.

For loading bays, position cameras to cover the vehicle approach, the loading point and the route into the building. Check that lorries, vans and open doors do not obstruct the view.

Use overlapping fields of view where the risk justifies it. This reduces gaps between cameras and helps track movement from one area to another.

Cover reception areas and cash points

Reception areas are important in offices, healthcare premises, schools and commercial buildings.

A camera can help record:

Avoid pointing a camera directly at a computer screen or collecting more personal information than necessary. The camera should serve a defined security purpose.

In shops and other retail premises, cash points and tills may require additional coverage. Position cameras to record activity around the area without unnecessarily recording private staff conversations or unrelated spaces.

Use a camera with sufficient resolution for the distance involved. A 4K security camera may support clearer digital zoom, but resolution cannot compensate for poor positioning or inadequate lighting.

Protect vulnerable equipment

Identify the assets most likely to be targeted or damaged.

These may include:

Use a dedicated camera for high-risk equipment where an overview camera cannot provide enough detail.

Consider the likely approach route. A camera should not only record the equipment. It should also capture the person approaching it.

For industrial sites and farms, check the view at different times of day. Seasonal changes can affect coverage. Summer growth, wet weather, darkness and parked machinery may create new blind spots.

Choose the correct field of view

Field of view determines how much of an area the camera can see.

A wider field of view can cover:

A narrower field of view may be better for:

Do not select the widest possible view for every camera. A wide image may show more area but provide less useful detail at a distance.

Plan each camera for a specific purpose:

Your CCTV survey should match each camera to the required level of detail.

Check lighting and night performance

Test CCTV during both daylight and darkness.

Look for:

A camera may produce a clear daytime image but poor footage at night. Infrared lighting can reflect from walls, windows, signs or nearby surfaces. Adjust the camera position and infrared settings to reduce glare.

Use consistent external lighting where appropriate. Avoid placing lights where they shine directly into the camera lens. Also avoid using fences, gates or other security features as climbing aids when planning lighting positions.

The final test should take place in real conditions. Walk through the property at night. Check whether a person’s face, clothing and direction of travel remain visible.

Respect privacy and neighbouring properties

CCTV should be proportionate to the security risk.

For domestic properties, aim cameras at your own entrances, driveway, garden, outbuildings and access routes. Avoid recording neighbouring gardens, windows or private areas.

If a camera must capture part of a pavement, shared access route or public area, review your responsibilities under UK data protection law. The GOV.UK guidance on domestic CCTV explains the responsibilities that may apply when cameras record beyond your property boundary.

Use privacy masking where available. Adjust the field of view before relying on digital masking. The best approach is to avoid unnecessary coverage at the planning stage.

Businesses should document:

The Information Commissioner’s Office CCTV guidance provides further information.

Use clear signage and sensible retention

Businesses and premises recording public-facing areas should use clear CCTV signage.

Place signs where people can see them before entering the monitored area. Signs should explain that CCTV is in operation and provide suitable contact information for the system operator.

Set a retention period based on the security purpose. Do not keep footage indefinitely without a clear reason. Delete recordings when they are no longer required, unless they relate to a specific incident or investigation.

Restrict access to authorised users. Use strong passwords and review who can view or export footage.

A professional CCTV installation should include correct date and time settings, secure recording and a clear process for exporting footage when required.

Review the system regularly

CCTV placement is not a one-time decision.

Review the system after:

Clean external camera covers. Check brackets, cables, recording status and image quality. Confirm that cameras still cover the intended areas.
