Is a video doorbell enough for home security?

Video doorbells have become one of the most popular entry points into smart home security. But are they actually enough on their own, or do they create a false sense of protection?

If you’re considering a video doorbell for home security, this helpful blog post breaks down exactly what these devices can (and can’t) do – and when you should consider a full home security system instead.

What a video doorbell actually does

A video doorbell is essentially a connected camera mounted at your front door. It combines motion detection, live video streaming and two-way audio so you can monitor and interact with visitors remotely. Most home security video doorbell devices offer:

• Motion alerts when someone approaches

• Live video feeds via your smartphone

• Two-way talk to speak with visitors

• Night vision recording

• Cloud or local video storage

For many households, this makes them a convenient first step into home security with a video doorbell, and they’re especially useful for monitoring deliveries (and hopefully preventing parcel theft), screening visitors before you open the door, and generally checking activity whilst you’re away. Overall, they improve visibility at your front door, but that’s only part of the picture.

Do video doorbells prevent crime?

Video doorbells can act as a visible deterrent and may discourage opportunistic behaviour. In fact, visible security tech is one of several factors that can make burglars think twice. However, bear in mind that criminals can still act quickly to steal parcels or break in, especially if you’re not home (which is why making your home look occupied whilst you’re away is incredibly important).

Ultimately, a video doorbell may help reduce risk, but it doesn’t eliminate it – especially if it’s your only line of defence.

The limitations of relying on a video doorbell alone

1. Coverage is limited to your front door

A video doorbell only monitors one entry point. It doesn’t cover back doors, windows, side entrances and indoor spaces, leaving large parts of your home unprotected.

2. It doesn’t stop intrusions

A video doorbell records and alerts, but it doesn’t actively prevent break-ins. Unlike a full home security system with video doorbell, it won’t:

• Trigger a loud siren

• Automatically alert a professional monitoring centre (if you have professional monitoring as part of a whole security system)

• Detect forced entry through doors or windows

3. It can be bypassed or disabled

Because it’s visible and externally mounted, a video doorbell is easy to spot and potentially easy to avoid or tamper with. These devices are just one layer of your home security and should be part of a broader system rather than relied on alone.

4. Performance depends on setup

The effectiveness of video doorbells relies heavily on factors such as correct positioning and installation, proper settings and a strong Wi-Fi connection. If any of these fail, you could miss critical events that would’ve been picked up by other security devices in your system.

5. Privacy and legal considerations (UK)

Video doorbells are legal in the UK, but there are important rules you need to follow. Crucially, if your camera records beyond your property (e.g., the pavement or neighbours’ properties, including gardens), you must comply with GDPR and data protection laws. These include:

• Minimising what you capture by aiming the video doorbell directly at your property

• Utilising built-in privacy zones in the device’s settings to block out surrounding properties

• Informing people they’re being recorded (e.g., if your video doorbell does capture footage of public paths or other properties and this can’t be avoided, you should place a sign informing people that recording is in progress)

• Disabling or limiting audio recording to avoid capturing private conversations

• Storing footage securely and not keeping it longer than necessary (e.g., a few days or weeks)

• Providing a copy of the footage if a neighbour requests to see footage containing them

The benefits of a full home security system

A home security system with video doorbells builds on the strengths of a doorbell camera whilst also addressing its weaknesses. Typically, this includes:

1. Whole-home coverage

• Entry sensors on doors and windows

• Motion sensors inside the home

• Optional outdoor cameras and indoor cameras

2. Active deterrence

• Loud sirens triggered during an incident

• Real-time alerts that demand attention

3. Professional monitoring (optional)

• 24/7 monitoring centres

• Emergency response if something happens

4. Integrated protection

Instead of a single device, everything works together, creating layered security.

Video doorbell vs full system: Which is right for you?

A video doorbell may be enough if:

• You live in a low-risk area

• You want visibility rather than full protection

• You’re mainly concerned about deliveries

• You’re starting small and building gradually

A full system is better if:

• You want comprehensive home protection

• You travel frequently or leave your home empty

• You want active deterrence (not just recording)

• You need protection beyond the front door

For most households, the best approach is combining both, which means using a video doorbell as part of a wider system.

A video doorbell is a smart, accessible upgrade that improves awareness and convenience. But on its own, it’s not a complete video doorbell home security solution. It helps you see what’s happening, but it doesn’t secure your entire home.

For real protection, layered security is key. Instead, you should find the best home security system with video doorbells, offering both visibility at your front door and protection throughout your entire home. With SimpliSafe, you can choose from a wide variety of home security packages to find one that suits your property and your needs, or you can even build your own security system to tailor it exactly to your preferences.

Frequently asked questions

Is a video doorbell enough for home security?

No – it’s a useful tool, but it only covers your front door and doesn’t actively prevent intrusions. Most experts recommend combining it with a full system, including cameras, entry sensors, motion sensors, glassbreak sensors and more. You can even find systems (like SimpliSafe’s) that combine security with safety, offering temperature sensors, water sensors and smoke detectors too.

Do burglars avoid homes with video doorbells?

Visible security devices like video doorbells can deter opportunistic criminals, but they’re not a guarantee. Determined intruders may still proceed, which is why it’s important to have other devices within your home security system that can record footage inside the home and trigger alarms.

Can a video doorbell replace CCTV?

Not entirely. A video doorbell provides limited coverage, whereas CCTV systems can monitor multiple areas around your home, not just the front door.

What’s the best home security system with video doorbell?

The best home security systems combine:

• Video doorbells

• Entry sensors

• Motion detection

• Indoor and/or outdoor cameras

• Optional professional monitoring

This creates a complete, layered defence rather than relying on a single device.
