Personal Safety Alarms for the Elderly: The 3 Types on the Market
Smartwatch, 4G alarm or Bluetooth button? A short guide to battery, subscription and where help actually comes from.
Searching for a personal safety alarm for an elderly parent quickly drowns you in brands and spec sheets. Underneath, there are really only three core types on the market – and the difference between them decides battery life, subscription cost and where help actually comes from.
1. The classic 4G alarm (watch or pendant)
A dedicated emergency device with a built-in SIM card. It usually calls a staffed monitoring centre that assesses the situation and dispatches help – relatives, home care or an ambulance.
Typical: rechargeable battery, monthly subscription incl. SIM and monitoring, the alarm goes to the monitoring centre, which dispatches help.
2. Smartwatch-based alarms
A standard smartwatch (for example an Apple Watch) with an alarm app. The watch uses either its own cellular connection or the paired phone to send the alarm.
Typical: rechargeable battery, a watch with its own mobile subscription or a paired phone.
3. The Bluetooth safety button
A small physical button on a keyring, lanyard or wristband. It is paired with a smartphone the user carries or that sits at home, and forwards the alarm directly to relatives.
Typical: battery up to 3 years (coin cell), one subscription per user (relatives join for free), alarm reaches relatives directly.

The key difference: where does help come from?
The 4G alarm (type 1) is built around a monitoring centre and works anywhere with mobile coverage. Help is relayed by an operator who assesses the situation and calls relatives or an ambulance.
The Bluetooth button (type 3) is built around relationships. It requires the smartphone to be nearby – but in return the battery lasts for years, and the alert goes straight to the family who know the user.
Which type fits your situation?
- Lives alone with no family nearby: a 4G alarm with a monitoring centre is usually the most robust option.
- Active elder, comfortable with tech: a smartwatch can work, but needs charging.
- Lives with or near relatives: a Bluetooth button is simpler and more personal, with no daily upkeep.
At Linucare we have chosen the Bluetooth path. Not because it suits everyone, but because it solves what most families actually need: one press that reaches the people they know. You choose who receives the alert, the button has no SIM card, and it does not need daily charging.
