Security Camera Security for Small Business: Keep Your Cameras From Becoming a Backdoor

Most small businesses install cameras to protect against theft, then forget about them. Meanwhile the cameras sit on the same network as the office computers, running old software and a password nobody ever changed.

That makes them one of the easiest ways into a business. Here is why cameras get hacked, and three practical steps to lock yours down without replacing everything.

1. Know why cameras are a target

An IP camera or network video recorder (NVR) is a small computer with a login page, and attackers scan the internet constantly for them. Cameras get hacked for a few reasons:

• Default or weak passwords: many devices ship with admin/admin or a password printed in the manual.
• Outdated firmware: cameras rarely update themselves, so known flaws stay open for years.
• Exposed to the internet: port forwarding for remote viewing puts the login page where anyone can find it.
• Trusted by the network: a hacked camera on your main network can be used to probe computers, servers, and the point-of-sale system.

Cameras are part of the wider IoT device risk most offices already have. The damage ranges from stolen footage of your staff and customers to a foothold for ransomware.

2. Secure the cameras and the recorder

Start with an inventory. List every camera, the recorder, and any cloud account. Then work through each one:

• Change default credentials to a long, unique password stored in a password manager.
• Create separate accounts for each person and remove the shared admin login.
• Turn on multi-factor authentication for any cloud or app account.
• Update firmware now and quarterly after that, or replace cameras the manufacturer no longer supports.
• Disable features you do not use, such as UPnP, old Telnet or FTP services, and guest viewing.

Track cameras in your IT asset list so they get patched like everything else.

3. Isolate cameras and fix remote access

Even a well-configured camera can have a flaw you do not know about, so assume one will be compromised and limit the damage.

• Segment the network: put cameras and the recorder on their own VLAN with no route to business computers. Our guide to network segmentation covers how.
• Remove port forwarding: check your router for rules pointing at the recorder and delete them.
• Use safe remote viewing: a vendor cloud service with MFA, or a VPN into the office, instead of an open login page.
• Limit outbound traffic: cameras usually only need to talk to the recorder and the vendor, which DNS filtering and firewall rules can enforce.

Also decide how long to keep footage and who may export it. Footage can be sensitive, and a clear retention rule fits with your data retention policy.

Common mistakes to avoid

• Leaving the installer's default password in place after setup.
• Putting cameras on the same network as the point-of-sale or file server.
• Port forwarding to the recorder so the owner can check it from a phone.
• Ignoring cameras once they work, so firmware is years out of date.
• Letting a former employee or installer keep a login. See our offboarding checklist.

The takeaway

Cameras are meant to protect your business, not expose it. Change the passwords, update the firmware, put the devices on their own network, and close any ports open to the internet. An afternoon of work removes one of the most common weak spots in a small office.

Frequently asked questions

Can security cameras be hacked?

Yes. Internet-connected IP cameras and recorders are a common target because many ship with default passwords, run outdated firmware, and are exposed to the internet through port forwarding. Attackers use them to watch your business, join botnets, or reach other devices on the network.

What is the safest way to view cameras remotely?

Avoid port forwarding. Use the manufacturer's cloud service with multi-factor authentication, or connect through a VPN to your network and view the recorder from inside it. Never expose a camera or recorder login page directly to the internet.

Should security cameras be on a separate network?

Yes. Put cameras and the recorder on their own VLAN or network segment with no access to computers, servers, or point-of-sale systems. If a camera is compromised, the attacker is stuck in a small, isolated area.

How often should camera firmware be updated?

Check at least quarterly and apply security updates promptly. Many cameras never update themselves, so put it on a calendar. If a camera no longer receives updates from the manufacturer, plan to replace it.

How long should a small business keep camera footage?

Many small businesses keep 30 to 90 days, depending on storage and any insurance, legal, or contract requirements. Decide on a retention period, document it, and restrict who can view and export footage.
