If your child has ever slipped out of the house, you have probably searched for a device that would make it impossible to happen again. There are many products, and the marketing can be persuasive. This guide compares the main types of devices by what they actually do, how they fit a child with sensory sensitivities, and what can go wrong. We do not recommend specific brands. Prices, features and subscription terms change often, so compare current details yourself before you buy.
Prevent or find: what job does each device do?
It helps to split devices into two groups:
- Prevention and alert devices tell you that a door, window or gate has opened, or that your child is moving somewhere they should not. They buy you seconds or minutes before your child is gone.
- Locating devices help you or law enforcement find your child after they have left. They do nothing to stop the exit.
Most families who face frequent wandering use both, plus physical barriers such as high locks and fencing. Our wandering and elopement safety plan shows how the layers fit together.
How do the main device types compare?
| Device type | What it does | Strengths | Limits to know |
|---|---|---|---|
| Door and window contact alarms or chimes | Sound when a door or window opens | Low cost, easy to install, nothing for the child to wear | Only help if someone hears and responds; batteries; children learn which doors are not alarmed |
| Pool and gate alarms | Alert when a gate opens or something enters the water | Target the highest-risk area in many Florida homes | Florida's pool law says a wearable child alarm does not count as a pool safety feature; an in-pool alarm must meet ASTM F2208 to count |
| Motion sensors and bed or floor pressure mats | Alert when a child gets up at night or enters a hallway | Catch night-time wandering before a door opens | False alarms; Wi-Fi models may stop working in a power or internet outage |
| Wearable GPS trackers (cellular) | Report the child's location to a phone app; some send alerts when the child leaves a set area | Can locate a child over long distances | Need charging, cellular signal and usually a monthly plan; accuracy varies; only work if worn |
| Short-range item trackers | Help locate objects through nearby phones | Small and cheap | Designed for belongings, not people; location updates depend on nearby devices; check the maker's own guidance before using with a child |
| Sheriff radio-tracking programs (such as Project Lifesaver) | Child wears a transmitter; trained deputies track its signal when you report the child missing | Run by trained searchers; no app or cell signal needed | Only in counties that run it; enrollment rules vary; you must report quickly |
| ID bracelets, shoe tags, clothing labels | Show your phone number and that your child is autistic | No battery, low cost | Do not locate your child; must be on the child |
To find out whether your sheriff offers a tracking program, see Project Lifesaver and sheriff registries in Florida.
Will my child actually wear it?
A tracker only works on a child who keeps it on. Sensory fit is often the deciding factor:
- Placement. Wrist, ankle, belt loop, shoe, a pocket inside clothing, or a lanyard. Ankle and inside-clothing options are harder to remove but can bother some children more.
- Weight and texture. Try a lightweight band or a soft cover. Some families start with a fabric band without the device.
- Locking clasps. Some bands need a tool to open. That keeps the device on, but think about comfort, skin checks and how fast an adult can remove it if needed.
- Water. In Florida, check whether the device is rated for water exposure, since many wandering children head for water and many families spend time at pools and beaches.
- Charging routine. A device that needs charging every night has to come off at a predictable time. Build charging into the bedtime routine so it does not get forgotten.
Tolerating a band or tag can be taught in small, rewarded steps, the same way children learn to accept a watch or a hat. A Board Certified Behavior Analyst (BCBA) can make it a goal if your family wants to use a wearable.
What should I check before buying a tracker?
FCC authorization
Devices that send radio signals, including GPS trackers with cellular or Bluetooth radios, must be properly authorized by the Federal Communications Commission before they are marketed or imported in the United States. Look for an FCC ID on the device or packaging and search it in the FCC's equipment authorization database. A missing FCC ID is a reason to be cautious.
Privacy and data
A tracker collects your child's location, often around the clock. Read the privacy policy before you buy and ask:
- Who can see the location data: only you, the company, or other partners?
- Is the data sold or shared for advertising?
- How long is location history stored, and can you delete it?
- Is the account protected with a strong password and two-step login?
The Federal Trade Commission's Children's Online Privacy Protection Act (COPPA) rule covers online services, apps and connected devices that collect personal information from children under 13. Under the rule, "geolocation information sufficient to identify street name and name of a city or town" is personal information, operators generally must get verifiable parental consent before collecting it, and parents can review and have their child's information deleted. If an app asks for access you do not understand, ask the company before agreeing.
Practical questions
- How often does the location update, and how accurate is it indoors and in dense neighborhoods?
- What happens when the battery is low or the signal drops? Do you get an alert?
- What does it cost after the first month: device, activation, monthly plan, contract length?
- Is there a way to share the location with law enforcement quickly if your child is missing?
Why do door alarms still matter so much?
Most wandering starts at a door. A simple alarm on every exterior door, the garage door and any gate to the pool or yard gives you the earliest possible warning. Tips that make alarms work better:
- Alarm every exit, not just the front door, including sliding doors and windows your child can reach.
- Use a distinct sound for exterior doors so you do not tune it out.
- Test batteries monthly, and keep spares.
- Check what happens in a power outage. Hardwired and Wi-Fi systems may go quiet when the power or internet is down. See power outages and autism.
- Combine with locks your child cannot open, such as high latches, following your landlord's or local fire-safety rules so adults can still get out quickly in an emergency.
A decision checklist
- Every exterior door, the garage and the pool gate have an alarm or chime that someone will hear.
- We have physical barriers too: locks, fencing, pool barriers.
- If we use a wearable, our child tolerates it, and charging is part of a daily routine.
- The device has an FCC ID, and we have read the privacy policy.
- We know the full yearly cost.
- We have asked our sheriff's office about Project Lifesaver or a local registry.
- Everyone who cares for our child knows the plan, including what to do first if our child is missing: call 911 and check water.
Do devices replace supervision?
No. Every device can fail: batteries die, signals drop, alarms get ignored, bands get removed. Treat devices as layers that buy time, not as a substitute for supervision, barriers and teaching. If your child does go missing, call 911 right away and check nearby water first; our page on what to do if your autistic child is missing walks through the first 10 minutes.
Skills are another layer. ABA can teach a child to ask before going outside, to wait at the door, to respond to their name and to stop when called. At Hope Center, programs are written by BCBAs and reviewed by our clinical director, and parents are trained weekly so the same rules are used at home.
