Short answer: Your cameras, door controllers and alarm panels are now devices on your network, so a camera with a default password is an IT problem and an unlocked equipment closet is a security problem. Convergence simply means planning both together: who can physically reach the equipment, who can log into it and who finds out when something goes wrong.
Why this matters for an ordinary business
The federal Cybersecurity and Infrastructure Security Agency (CISA) published a guide on cybersecurity and physical security convergence. Two of its points apply directly to small and mid-sized businesses. First, connected devices widen the number of places an attacker can target. Second, a gap in physical access control can let someone walk in and plug a USB device or other hardware into your network.
You do not need to be a power plant for that to matter. A medical office in Franklin, a manufacturer in Cleveland or a property management company in Chattanooga all have the same basic setup: cameras, a recorder or cloud video service, some door access and an office network, often installed by different people at different times.
Where the two overlap in a typical building
- The camera recorder and network switch sit in an unlocked closet or a ceiling space anyone can reach.
- Cameras still use the installer's default username and password.
- The access control software runs on an old office PC nobody updates.
- Everyone views cameras through one shared app login.
- A former employee's key card was turned off, but their camera app login was not.
- Security devices sit on the same network as the front desk computers and guest Wi-Fi.
A practical checklist
- List every connected security device. Cameras, recorders, door controllers, alarm panels, intercoms and gate operators. You cannot secure what you have not counted.
- Replace default passwords and shared logins. Give each person their own login so you can remove one without resetting everyone.
- Separate the security devices on the network. Ask whoever manages your IT to put cameras and door hardware on their own network segment, away from guest Wi-Fi and office computers.
- Lock the room where the equipment lives. Put that door on access control so there is a record of who opened it and when.
- Keep firmware and software current. Put updates on a schedule instead of waiting for something to break.
- Use one offboarding checklist. When someone leaves, their key card, alarm code and camera app access all come off the same day.
- Review remote access every few months. Know exactly who can view cameras or unlock doors from a phone.
How Turner Security fits in
Turner Security installs and supports business security cameras, access control and intrusion alarms from our offices in Smyrna and Chattanooga. If you are not sure where your equipment sits, who has logins or who has remote access, we can go through those questions with you when we look at your system. We also work with the Eagle Eye cloud video platform, which moves viewing and video management to a cloud service rather than relying only on a recorder in a back room. When you need help, our help desk can resolve most service issues remotely before a truck is ever sent.
Our sister company, TechCore, handles business IT with the same owners and team, which makes it easier when a security question crosses into the office network.
Mistakes to avoid
- Assuming the camera installer handled cybersecurity. Ask what passwords and network settings were used, in writing.
- Leaving remote viewing wide open to the internet because it was the fastest way to get the app working.
- Splitting ownership with no one in charge. If IT thinks security owns the cameras and security thinks IT does, nobody updates them.
Frequently asked questions
Can business security cameras be hacked?
Any connected device can be targeted, especially with default passwords or outdated firmware. Unique logins, regular updates and keeping cameras off your main office network lower the risk a lot.
Should cameras be on the same network as our computers?
Ideally no. A separate network segment keeps a compromised camera from becoming a path to your files, and keeps heavy video traffic off your business network.
Who should hold the admin passwords for our security system?
You should. Your installer may need access to support the system, but the business should own the admin account and know who else has one.
