Smart Devices in Small Offices and Home Offices: What to Adopt and Avoid
Smart speakers, video doorbells, Wi-Fi cameras and app-controlled plugs have moved from the lounge room into the workplace. They turn up in small offices, shopfronts and, most of all, in the home offices where many staff now work part of the week. Each one is a small computer connected to the same network as your business laptops.
Some of these devices are genuinely useful. Others add risk for very little benefit. This guide covers which smart devices make sense in a small office or home office, which to avoid, and the security basics that keep them from becoming a back door into your business.
Why smart devices matter for business security
Smart devices are attractive to attackers for a few simple reasons:
- Many ship with weak or shared default passwords.
- Cheaper brands may stop releasing security updates soon after sale, or never release any.
- They usually sit on the same Wi-Fi as work computers, so a compromised camera can be a stepping stone to a laptop.
- Cameras and microphones can capture conversations, screens and documents you would never email to a stranger.
When staff work from home, the business has no control over that network unless it plans for it. Our guide to remote work security for small businesses covers the wider picture.
Adopt: smart devices that earn their place
Smart lighting and climate schedules
Schedules and occupancy sensors that switch off lights and air conditioning after hours are low risk and save energy. Choose a reputable brand, keep the app account protected and update the hub or bridge when prompted.
Smart access control
Individual cards, fobs or phone credentials beat shared keys and alarm codes. You can see who entered and remove access the moment someone leaves. For an office, pick a system designed for business use with proper admin controls.
Business-grade cameras
Cameras can deter theft and help after an incident. Use well-known brands with a published update policy, protect the cloud account with multi-factor authentication and place cameras so they do not capture screens, keypads or private areas. Let staff and visitors know where cameras are.
Meeting room devices built for business
Meeting bars and room systems certified for Microsoft Teams or Zoom are designed to be managed and updated centrally. They are a much safer choice than a consumer smart display sitting on the meeting room table.
Avoid: devices and habits that add risk
Cheap, unbranded gadgets
A no-name camera or plug bought online can be very cheap for a reason. You often cannot tell who makes it, where its data goes or whether it will ever be patched. If you cannot find a support page and a clear update policy, leave it out of the business.
Voice assistants where confidential conversations happen
Smart speakers listen for a wake word and can mishear. Keep them out of meeting rooms, reception areas where client details are discussed, and home office spaces where staff take confidential calls. At the very least, mute the microphone during work.
Everything on one network
Putting smart devices on the same Wi-Fi as your work computers is a very common mistake. If one device is compromised, everything on that network is exposed.
Set and forget
Devices that never get updated, apps that nobody checks and accounts tied to a former employee’s email address all build up over time. Every device needs an owner.
Australia’s smart device security standard
From 4 March 2026, most smart devices made for personal or household use and supplied in Australia must meet a new security standard. Manufacturers must avoid universal default passwords, provide a way to report security issues and publish how long the device will receive security updates. It is a useful step, but devices made before that date are not covered, so older stock and existing gadgets still need checking. Look for the stated support period before you buy.
Security basics for the small office and home office
- Separate networks: put smart devices on a guest or dedicated network, away from work computers. Most modern routers can do this.
- Change default passwords: use a unique password for every device and its app, stored in a password manager.
- Turn on multi-factor authentication for every cloud account that controls a camera, lock or hub. Our MFA guide explains how.
- Update regularly: switch on automatic updates where possible and check the rest monthly.
- Review privacy settings: turn off features you do not use, such as voice recordings, cloud clip storage or sharing with third parties.
- Keep a list: record every device, who owns it and when its support ends.
- Retire devices properly: factory reset before disposal and remove them from the app account.
For staff working from home, a short written guide on home Wi-Fi and smart devices goes a long way. Pair it with endpoint protection and monitoring on work laptops, which is part of our managed IT security service.
Key takeaways
- Adopt smart devices that solve a real problem and come from brands with a clear update policy.
- Avoid cheap, unbranded gadgets and always-listening devices in confidential spaces.
- Keep smart devices on a separate network and protect every account with MFA.
- Check the support period before you buy, and keep a list of what is connected.
