CCTV cameras, video doorbells, smart plugs and smart TVs make life easier, but each one is a small computer connected to the internet. If not set up carefully, strangers can view your camera feed or misuse your devices.
Change default passwords
Many cameras and DVR/NVR recorders come with simple default passwords like “admin” or “123456”. These are well known to hackers. Change them on day one to a strong, unique password.
Update the firmware
Manufacturers release updates that fix security holes. Check the device app or settings for updates every few months, and turn on automatic updates where possible.
Use the official app only
Download camera apps only from Google Play or the App Store, and from the brand’s official listing. Avoid unknown apps that promise free cloud viewing.
Turn off what you do not use
- Disable remote access if you only watch the camera at home.
- Turn off UPnP in your router unless a device truly needs it, because it can open ports automatically.
- Remove old devices from your network and from the apps.
Separate your devices
If your router supports a guest network, connect smart plugs, cameras and other gadgets to it. Then, even if one device is compromised, it cannot reach your laptop or phone.
Think about camera placement
Point indoor cameras away from bedrooms and private areas, and switch them off when the family is at home if you do not need them.
Check who has access
Review shared users in the camera app. Remove former staff, tenants or relatives who no longer need access.
Need a stable connection for cameras?
For DVR and NVR systems, a wired connection to the router gives the most reliable recording and remote viewing. SF Networking support can advise on the best setup.
