How Secure Are Video Doorbells Compared to Traditional Locks?

Video doorbells are now common in many homes. They let you see who’s at your door, talk to visitors through your phone, and even record video footage. But here’s a question many homeowners ask:

Can a video doorbell replace a traditional lock? Or should it be used as an extra layer of security?

In this blog, we’ll look at how secure video doorbells really are, how they compare to regular locks, and the best way to use both together for better home protection.

What Is a Video Doorbell?

A video doorbell is a smart device that works as both a doorbell and a security camera. When someone presses it (or even just comes close), it sends a live video feed to your smartphone.

Some models also include:

• Two-way audio
• Motion detection
• Night vision
• Video recording
• Integration with smart home systems

Popular brands include Ring, Nest, Arlo, and Eufy.

How Do Traditional Locks Work?

A traditional lock uses a mechanical system that keeps your door shut unless you insert the correct key. Deadbolts, knob locks, and mortise locks are the most common types used in homes.

When installed properly, these locks are strong, long-lasting, and offer physical protection against break-ins.

Can a Video Doorbell Stop a Break-In?

No, a video doorbell can’t stop someone from opening your door. It’s not a lock. Instead, it helps you monitor activity at your door and can scare off unwanted visitors.

Here’s what it can do:

• Alert you when someone approaches, even if they don’t knock
• Let you talk to strangers without opening the door
• Record video if something happens, like package theft
• Help police if a crime takes place

But if your actual lock is weak or broken, the door is still easy to open, even with a camera in place.

Pros of Video Doorbells

• Let you answer the door remotely
• Provide video proof of who came and when
• Help prevent package theft
• May scare off burglars who know they’re being recorded
• Work well with other smart devices like alarms or smart locks

Limitations of Video Doorbells

• Do not physically stop a break-in
• Can be blocked, removed, or damaged by intruders
• Depend on Wi-Fi and power to function
• May have delays in notifications or live view
• Recordings may be stored online, raising privacy concerns

So while they are useful, they are not a replacement for strong door locks.

How Do Video Doorbells and Locks Work Together?

The best approach is to use both. A video doorbell adds eyes and awareness, while a good lock provides the actual protection.

Here’s how they work together:

• You see who’s at the door through your video doorbell
• You speak to the person without opening the door
• If you trust them, and you have a smart lock, you can unlock it through an app
• If you don’t trust them, you simply ignore the knock — while your door stays locked

In case of an attempted break-in, the video doorbell captures footage, and your lock holds the door shut.

Are Video Doorbells More Secure Than Regular Locks?

No. Video doorbells are not more secure than traditional locks. But they add another layer of protection by helping you:

• Watch your front door in real time
• Avoid opening the door to strangers
• Get alerts about suspicious activity
• Keep a record of visitors
• But if your door has a weak or outdated lock, a burglar can still get in — camera or not.

What’s the Best Setup for Home Security?

For the best protection in 2025, use:

• A strong, high-quality deadbolt lock (mechanical or smart)
• A video doorbell with real-time alerts and video storage
• Outdoor lighting or motion lights to keep the entryway visible
• A backup security system like an alarm or smart sensors

This mix of physical and smart security is the best way to protect your home.

Final Thoughts

A video doorbell is a great tool. It helps you stay aware of who’s outside your home and gives you more control over how and when to open your door. But it doesn’t actually secure the door. That’s the job of your lock.

If you're serious about home security, don’t rely on a camera alone. Use a strong lock and let the video doorbell be your second line of defense.

Both have a role to play. Together, they make your home smarter — and safer.
