Best Door Alarms for Dementia

Dementia is a term given to a group of mental disorders, such as Alzheimer’s, Parkinson’s and Huntington’s disease. Each of the above diseases tends to deteriorate over time, with differing symptoms.

What Is Dementia Wandering?

Patients with Alzheimer’s disease are often known to wander. Any Alzheimer’s patient who is still mobile will wander.

Wandering is extremely dangerous. Patients may easily forget who they are, may become lost or disoriented. They are at high risk of accident, muggings and robbery, getting left out in extreme cold or heat, and many other threats

Wandering is hard on the patient’s families as well. The constant struggle to keep tabs on your loved one, not knowing when they might disappear or worse can take its toll, leading to restlessness, anxiety, fear and paranoia among them. Countless sleepless nights running around trying to find the patient also extracts a price from the body, which needs sleep to function properly.

Why Not Simply Lock the Doors?

One option, of course, is to lock the doors at all times, especially when sleeping with a lock that has a specific key or number combination unknown to your loved one. However, in the case of a fire hazard, this can be dangerous, as they may not be able to escape in time.

It is also possible that they might take offense to such constant scrutiny, especially if this practice is implemented during the day as well. It is important that patients suffering from dementia should be allowed to maintain their dignity.

What Is a “Door Alarm”?

A door alarm is a device that detects when a door is opened and alerts others in the house/area that someone has left the house. Usually, it consists of a device mounted on the door which is integrated with an alarm or a chime that is loud enough to be heard from a distance.

Advanced options also include remote-controlled operation, remote alarm (which is not played at the door, but instead somewhere the caregiver or family member can hear it.

Some alarms are also combined with remote-sensor wrist bands that can be put on the person that needs to be tracked. This way an alarm is raised only if the person that needs to be tracked leaves the house, instead of doing it every time anyone leaves.

What Are the Various Types of Door Alarms?

String Alarm

A string alarm is just that – a string, connecting the door and the door frame by a magnet. When the door opens, it causes the string to detach, thus sounding an alarm. To stop the alarm, simply reconnect the magnet back in its original position.

Passive InfraRed (PIR) Alarms

A PIR sensor can detect changes in the infrared radiation being emitted by an object upon it. The PIR alarm uses this technology to check if the plane across the door is changing, and raises an alarm when this plane is broken.

The great thing about PIR alarms is that they can detect a person leaving from the door even if the door is currently open. Since the technology only looks at the plane of the door and detects heat signatures in that plane, a hot body entering the plane is registered whether or not the door itself is in place. Thus an alarm is raised every time someone passes through the frame of the door.

Magnetic Door Alarms

A magnetic door alarm is nothing but two sensors containing magnets, one on the door and the other on the door frame, in close contact with each other.

As long as the two magnets are in each other’s presence (not more than 10-15mm apart), the alarm will remain inert. As soon as the door is opened, the connection between the two magnets is lost and an alarm is raised, and it can be reset only when the two magnets are connected back to each other.

Floor Sensor Alarms

Floor sensor alarms use a combination of weight sensing floor mats and door alarms. When your loved one stands on the mat, the change in weight is registered and an alarm is raised.

Floor sensor alarms can be preset to either alarm immediately or to allow a small time for the person to exit and return before sounding. Since they are pressure sensitive and not dependant on the door per se, they can be used to curb wandering at the bedside itself and can warn caregivers that much earlier.

Remote Sounding Alarms

If you do not wish to startle the person with dementia who is opening a door, you can use a remote sounding alarm that will sound near the caregiver instead of at the door.

These alarms typically have two parts: a transmitter that is connected to the door and is activated when it is opened, and a receiver that is placed near the caregiver and is connected with the alarm.

In the event of your loved one wandering out, the transmitter will send a signal to the receiver which will activate the alarm, thus waking up the caregiver.

Keypad Locks

Keypad locks require a degree of awareness to unlock (since the combination has to be entered by hand). Therefore they can be used to prevent your loved one from wandering out.

Since keypad locks can be connected to a fire alarm/smoke detector, they aren’t a threat in case of fire, which is the problem with normal locks.

Gps Alert Systems

GPS is a technology used for tracking and locating things. A GPS alert system can be included in many things – even small ones like shoes, watches or bracelets. It is possible to track when a person breaches a perimeter (say 50 metres) from the house, or else you can simply track continuously.

#7 Entrance Alert Chime with PIR Sensor

This is the only PIR door alarm on our list. PIR alarms usually come as part of an alarm system and are not sold independently. This is one of the few that comes as a self-contained unit.

Entrance Alert Chime with PIR Sensor

To use the sensor, simply mount it on the door with either the double-sided tape provided as part of the package or else screw it in. Once turned on, the sensor will detect if there is a change in the heat signature of the monitored zone, and will play one of two available chimes.

There is also a sensitivity setting, to ensure that inanimate objects and small animals can pass through undetected so that unnecessary alarm is not raised. For best results, the higher the sensor is mounted the better is the range of detection.

#8 Ideal Security SK630 SOLO Pressure

The Ideal Security SK630 is the only floor sensor alarm on our list.

Ideal Security SK630 SOLO Pressure

It consists of a pressure-sensitive mat, which when stepped on is able to alert you about the coming and going of a loved one who may be wandering out. Keep in mind that the mat is sensitive to any pressure above 1 pound/per square inch, therefore it will be activated even due to the entry/exit of small animals.

An alarm unit is connected to the pressure-sensitive mat by a 30 feet wire (which can be extended up to 65 feet with an optional extension cable which is not part of packaging).

There are two modes of operation: chime and alarm. There is no volume control in either mode. In alarm mode, there will be a 105dB sound triggered, whereas, in chime mode, a ding-dong sound will be activated.

The alarm works on a 9V battery, which would ideally last about 5 months.

When covered with a waterproof mat, this device can be used in an outdoor mode as well.


  • Since it is pressure sensitive and uses the mat as the main triggering point, this device can be used anywhere (not just the door). It can prevent wandering at the bed itself, for example
  • It has a super long connecting wire, which helps alert the caregiver in another room
  • Fairly inexpensive for the technology that it is using.


  • Triggering can happen due to many causes and therefore alarm can be erratic
  • The wire connecting the mat and the alarm is very thin and easily damaged
  • The packaging of the mat causes permanent creasing on the mat
  • The alarm can be too loud
  • 9V batteries are fairly expensive and this device is battery-intensive
