Connected devices in business: cameras, sensors and smart equipment without the security risk
Who this is for: businesses adding IP cameras, access control, point-of-sale equipment or sensors to their network.
The Internet of Things (IoT) simply means everyday equipment that connects to your network: IP cameras, door controllers, receipt printers, environmental sensors and smart displays. They are useful, and they are also small computers that are often forgotten once installed. Poorly set up devices are a common way into a business network.
Change every default password
Many devices ship with a well-known username and password. Attackers scan the internet for exactly those. Set a unique, strong password on every device during installation, and record it securely.
Keep devices on their own network
Cameras and sensors should not sit on the same network as your accounts computer and file server. Place them on a separate network segment (a VLAN) with only the access they need. If one device is compromised, the rest of the business stays out of reach. This is straightforward with business-grade switches and routers.
Do not expose devices directly to the internet
Avoid opening ports on your router so that you can view cameras remotely. Use a secure remote-access method, such as a VPN or the manufacturer’s managed cloud service with multi-factor authentication switched on.
Update the firmware
Manufacturers release fixes for security flaws. Choose reputable brands that keep publishing updates, and schedule a regular check. Replace devices that are no longer supported.
Plan cabling and power
Wired cameras powered over Ethernet (PoE) are more reliable than Wi-Fi cameras, and a UPS on the recorder, switch and router keeps your footage and your alarms working through load shedding. Good cabling is a one-off cost that pays for itself in fewer callouts.
Think about the recorded data
Camera footage of staff and customers is personal information under POPIA. Keep recordings only as long as you need them, restrict who can view them, and display clear signage.
One team for the whole system
Retail and hospitality businesses often coordinate separate suppliers for tills, cameras and the network that connects them. StepEdge supplies, installs and supports POS and CCTV systems together with the network they run on, so responsibility sits in one place. Ask for a quote for your premises.
