The Straits Times reports that 88,400 Singapore seniors lived alone in 2025, although most still lived with a spouse or children. 1 For families considering support at home, our view is that living arrangements should start a conversation, not determine the answer.
Living alone should not be treated as proof that someone needs monitoring. An older parent may welcome additional support while wanting their everyday life to remain private. Before choosing any technology, talk with them about the information they would be comfortable sharing.
This is where the privacy discussion becomes practical. What does a device detect? What appears in the app? Who can access that information, and how will the family use it?
The following questions can help families explore home-monitoring technology while keeping the person’s preferences at the centre of the decision.
Start with what the person wants
Imagine an older parent who enjoys quiet mornings, prepares their own meals and likes deciding when to call family. Their adult child wants to know when something might need attention. Both perspectives deserve space.
Rather than deciding what to install first, discuss the situations you want help with. Is the concern about knowing when to check in? Understanding a notification? Finding support that fits around existing routines? Be specific about the purpose, and include the person living in the home when exploring options.
Ask: “What would you find helpful, and what would make you uncomfortable?”
Look beyond the word “camera-free”
The absence of a conventional camera does not answer every privacy question. A device may use another kind of sensor and still produce information about activity in the home.
Ask the provider to explain what the system detects and what becomes visible in the app. Request a demonstration rather than relying only on a product description. Does the app display an activity status, a sensor-generated image, a notification history or something else? What can someone reasonably understand from that information, and what remains uncertain?
These are questions to investigate for each product, rather than assumptions about what all monitoring systems provide.
Ask: “Can you show us exactly what a family member would see?”
Understand who can access the information
Think about who needs to be involved. One family member may handle most check-ins, while another helps when they are unavailable. Discuss those responsibilities before assuming that everyone needs access.
Ask the provider how accounts and permissions work, whether access can be changed, and what happens when someone no longer needs to be involved. Clarify whether the provider or its service partners can access information, and for what purposes.
Singapore’s Personal Data Protection Commission advises organisations to make their data-protection policies clear and accessible before collecting personal data. Reading the relevant policy is a useful starting point for your questions. 2
Ask: “Who can access this information, and how is that access managed?”
Ask what happens to the data
Information shown on a phone is only part of the picture. Ask where the information is processed and stored, how long it is retained, and what happens if you stop using the service.
Request explanations in language your family understands. If the policy is unclear, ask the provider to walk you through the parts relevant to the product. A useful discussion should also cover whom to contact with privacy concerns and how to ask about correcting or deleting information.
Ask: “What happens to our information while we use the product, and when we stop?”
Agree on what happens after a notification
Privacy also involves how family members use the information they receive. Discuss when someone should call, who could check in and what to do if the usual contact is unavailable. Avoid assuming that a notification tells the whole story or that another person has already responded.
It is also worth agreeing on everyday boundaries. A family member’s access to information should support the arrangement you have discussed together. Revisit that arrangement when preferences, routines or caregiving responsibilities change.
Ask: “How will we use this information in a way everyone understands?”
Exploring HeatSig for your home
HeatSig combines everyday lighting with thermal sensing and app notifications when detected activity may require attention. Its product page describes a process of detecting thermal activity, analysing it and notifying connected family members or caregivers. 3
When considering HeatSig, ask to see the actual fixture and app. Bring questions about what is displayed, who can access it and how information is handled, alongside questions about installation and costs. The aim is to understand whether the product fits the person, the household and the support available.
