Setting up a CCTV system at home feels straightforward at first glance. A few cameras, some wiring, a monitor – what could go wrong, right?

But many homeowners discover a little too late that small mistakes during home CCTV installation can lead to poor coverage, blind spots, or worse, footage that’s useless when it matters most.

Before you grab your toolkit, let’s walk through the common pitfalls you’ll want to steer clear of. Knowing what to avoid now could save you a lot of frustration. And, protect your home the way you intended.

Placing Cameras Without a Clear Strategy Wastes Time and Money

It’s tempting to start drilling and fixing cameras the moment you unbox them. But without a proper plan, you’re likely to miss key areas or end up with overlapping views that waste storage space.

Effective home CCTV installation always begins with a site survey. Walk around your property and think like an intruder.

Ask yourself:

• Where are the most vulnerable entry points?
• Are there dark corners where someone could hide?
• Which areas need constant monitoring like the front gate, backyard, or driveway?

Draw a rough layout and plan your camera placements before installing anything. This way, you will maximise your cameras’ potential, cover blind spots, and make full use of your system. Thinking twice before drilling once could save you a costly reinstall.

Mounting Cameras Too High or Too Low Could Cost You Clear Footage

Height matters more than most people realise. Mount cameras too high, and faces will be hard to recognise. Mount them too low, and they’ll become easy targets for tampering.

Ideally, outdoor cameras should be mounted at around 2.5 to 3 metres high – just out of easy reach but low enough for facial recognition. Indoors, the same logic applies, especially at entry points like doors and windows.

And always angle your cameras properly. A slight downward tilt gives you better visibility without stretching the lens’ capability too much.

A Home CCTV Installation Pro Tip: Test different angles before finalising the screws. Taking a bit more time now could save you a lot of trouble down the line.

Forgetting About Lighting Leaves You Blind After Sunset

A lot of DIY installers trust the camera’s specs blindly. Especially the ones boasting night vision or infrared (IR) capabilities. But the truth is, even the best CCTV cameras can struggle without proper lighting support.

Poorly lit areas can lead to:

• Grainy, unusable footage
• Missed details during crucial moments
• Cameras constantly switching between day and night mode, reducing lifespan

If you’re installing outdoors, invest in motion-activated floodlights or ensure streetlights provide enough illumination. Indoors, small night lights near hallways and entry points can make a big difference without being too harsh.

Choosing the Wrong Camera Type Creates More Problems Than It Solves

Not all CCTV cameras are built the same. And picking the wrong type for your home can compromise your entire security plan.

For example:

• Dome cameras are ideal for wide indoor spaces like living rooms.
• Bullet cameras work best outdoors because of their long-range focus.
• PTZ (Pan-Tilt-Zoom) cameras are great if you want flexible viewing but are more expensive and complex to set up.

Think about what each area needs before buying your cameras. It’s all about the right tool for the right job.

And yes, sometimes a mix of camera types gives the best overall protection.

Ignoring the Importance of Wi-Fi Strength Leads to Constant Frustrations

Modern home CCTV systems often rely on wireless technology. While going wireless looks cleaner and simpler, a weak Wi-Fi signal can cause lagging, poor video quality, or even total disconnections.

If you’re placing cameras far from the router, you might need Wi-Fi extenders or mesh systems to ensure a stable connection. Otherwise, all those sleek features like remote viewing on your phone could become a nightmare of constant buffering.

When planning your home CCTV installation, do a quick speed test in the spots where you intend to install cameras.

If signal strength drops below 50%, it’s best to address the network first.

Overlooking the Power Source Risks Your Security When It Counts

Power cables might seem old school compared to batteries and solar panels, but reliable power is essential.

If you’re using wired cameras, make sure the cables are weatherproof and properly secured to avoid accidental disconnections. For wireless systems, regularly check the battery life and keep spare batteries handy.

Many homeowners forget about backup power too. A sudden blackout could make your entire CCTV system useless unless you have a UPS (Uninterruptible Power Supply) in place.

Having stable power means your cameras stay on even during emergencies – when you need them the most.

Forgetting About Data Storage Means Losing Critical Footage

Storing CCTV footage without a plan is like typing a crucial report and forgetting to hit save. Many homeowners rely only on the default microSD cards that come with the cameras. But they usually fill up fast.

Think about:

• How long you want to keep your footage (7 days, 30 days, or longer?)
• Whether you prefer local storage (DVR/NVR systems) or cloud backups

If you’re using higher resolution cameras, like 4K, you’ll need more storage to keep up. Invest in sufficient storage or choose smart systems that automatically overwrite old footage.

Most importantly, always encrypt your storage and set strong passwords. The last thing you want is for your recordings to end up in the hands of malicious users.

Not Knowing the Law Could Land You in Trouble

If you’re installing CCTV at home, you need to know that Singapore has rules about how you use it.

Under the Personal Data Protection Act (PDPA), homeowners must be mindful if their CCTV systems capture areas beyond their property. This could include public spaces, neighbours’ homes, or even shared corridors in HDBs and condominiums.

Some key things you should know:

• Limit your recording range to your own property wherever possible.
• Put up notices if your cameras cover any shared spaces.
• Use the footage only for security purposes and not for sharing publicly or online without consent.
• Respond promptly to any feedback or complaints if someone raises concerns about your cameras.
