Ankle Bracelet Voice Monitoring: Project Lifesaver's Features Explored

Project Lifesaver is a radio-frequency technology-based system used by law enforcement search teams to find missing individuals. It involves attaching a radio transmitter device to the wrist or ankle of persons at risk of wandering. The device emits an inaudible pulse once per second that can be picked up by a hand-held directional antenna. While it is known that the ankle bracelet from Project Lifesaver monitors the location of the wearer, it is unclear if it also monitors voice. However, it is known that some ankle bracelets used for house arrest have microphones, but the use of these microphones is restricted to voice identification.

The Project Lifesaver bracelet is a radio transmitter

The Project Lifesaver bracelet is attached to the wrist or ankle of persons at risk of wandering due to conditions such as dementia, epilepsy, Alzheimer's disease, autism, Down syndrome, and other disabilities. It is a proven and reliable technology that has successfully located over 4,000 individuals in an average time of less than 30 minutes, with no reported serious injuries or deaths.

Each bracelet has a unique radio frequency, allowing the Project Lifesaver search team to positively locate and identify the person who has wandered away. The technology is constantly being improved to ensure the most effective methods are used in the prevention of wandering and the recovery of clients.

While some ankle bracelets used for monitoring individuals under house arrest may have microphones, there is no indication that the Project Lifesaver bracelet includes this feature. The focus of the Project Lifesaver bracelet is solely on transmitting a tracking signal to facilitate the swift and safe recovery of at-risk individuals.

The bracelet is attached to the wrist or ankle

The Project Lifesaver bracelet is attached to the wrist or ankle of persons at risk of wandering. This includes individuals with dementia, epilepsy, Alzheimer's disease, autism, Down syndrome, and other disabilities. The bracelet is attached using a plastic or nylon wristband. It is a radio transmitter device that emits an inaudible pulse once per second in the FCC-allocated and licensed 216 MHz frequency range. This signal can be picked up by a receiver operated by public safety officers or a hand-held directional antenna.

The Project Lifesaver bracelet is a lightweight, battery-operated device that continuously emits an automatic tracking signal every second, 24 hours a day. The signal can be tracked over several miles, and each bracelet has a unique radio frequency, allowing for positive identification of the individual. This technology has significantly reduced search times, with an average recovery time of less than 30 minutes and no reported serious injuries or deaths in over 2000 searches.

It is important to note that the Project Lifesaver bracelet does not include voice capabilities. While some ankle bracelets used for criminal probation may have microphones, the Project Lifesaver bracelet is solely for tracking purposes and does not have this feature. The bracelet is designed to support individuals with special needs and their caregivers by providing timely response and location services in the event of wandering.

The bracelet is typically attached to the wrist or ankle, but there are also sensory-friendly wearing options available. These include a sleeve for wearing the device in a pocket, a soft and tagless undershirt with a special pocket, and a waist belt. These alternatives are designed to accommodate individuals who may be sensitive to wearing the bracelet directly on their wrist or ankle.

By attaching the Project Lifesaver bracelet to the wrist or ankle, individuals at risk of wandering can be effectively located and identified, providing peace of mind and safety for both the individuals and their caregivers.

The radio transmitter emits an inaudible pulse once per second

The Project Lifesaver bracelet is a battery-operated, one-ounce radio transmitter emitting an automatic tracking signal every second, 24 hours a day. Each bracelet has a unique radio frequency, which allows the search team to positively locate and identify the person who has wandered away. The signal can be tracked on the ground or in the air over several miles.

The Project Lifesaver program has been successful in locating over 4,000 individuals in an average time of less than 30 minutes, using only two to three public safety responders. It is considered the most reliable search and rescue program in the world and has helped to save time, money, and most importantly, lives.

It is important to note that while the Project Lifesaver bracelet does not have voice capabilities, some ankle bracelets used for house arrest may have a built-in microphone. However, in California, it is against the law for the state to use this microphone to eavesdrop on conversations, and it is only to be used for voice identification.

The signal is tracked on the ground or in the air

The Project Lifesaver bracelet is not a passive ID bracelet. It is a one-ounce, battery-operated radio transmitter emitting an automatic tracking signal every second, 24 hours a day. This signal is what allows the person wearing the bracelet to be tracked on the ground or in the air. The signal can be tracked on the ground for approximately 1.5 km or in the air for several kilometres. New transmitters can even double the transmission range.

The radio transmitter device is attached to the wrist or ankle of the person at risk of wandering. The transmitter emits an inaudible pulse once per second that can be picked up by a hand-held directional antenna. The radio-tracking signal becomes stronger and louder as one gets closer to the missing person.

When caregivers realise the person wearing the device is missing, they contact the Search and Rescue (SAR) centre, and trained operators start the search by directing the antenna according to the audible sound, indicating the missing person’s direction.

Each bracelet has a unique radio frequency, so the Project Lifesaver search team can positively locate and identify the person who has wandered away from home or a care facility. This is how the signal is tracked on the ground or in the air over several miles.

The Project Lifesaver bracelet is not a passive ID bracelet

The Project Lifesaver bracelet is a sophisticated device that goes beyond the capabilities of a typical passive ID bracelet. It is a specialised tool designed for individuals with special needs, including those with cognitive conditions or behavioural tendencies that put them at risk of wandering. Here's what sets the Project Lifesaver bracelet apart:

Radio Transmitter Technology: The bracelet incorporates a battery-operated radio transmitter that emits an inaudible pulse once per second, operating in the FCC-allocated and licensed 216 MHz frequency range. This signal can be detected by receivers or directional antennas operated by public safety officers or trained search and rescue teams.

Wide Tracking Range: The tracking signal transmitted by the bracelet can be picked up over several miles, providing a broad range for search and rescue operations. This extended range significantly increases the chances of locating individuals who have wandered away from their homes or care facilities.

Unique Radio Frequency: Each Project Lifesaver bracelet is assigned a unique radio frequency, enabling the search team to positively identify and locate the individual. This feature ensures accurate identification and prevents confusion during search missions.

Reduced Search Times: The advanced technology of the Project Lifesaver bracelet has significantly reduced search times. In over 2,000 searches, the average recovery time has been less than 30 minutes, demonstrating the efficiency and effectiveness of the system.

Specialised Search and Rescue Team: Project Lifesaver is not just about the bracelet; it's also about the dedicated search and rescue team that responds swiftly when a person enrolled in the program goes missing. This team is specially trained and equipped with the necessary tools to conduct efficient searches, utilising the bracelet's unique tracking capabilities.

As such, the Project Lifesaver bracelet is an active and dynamic component of a comprehensive search and rescue program, providing peace of mind and improved safety for individuals prone to wandering. Its real-time tracking capabilities and unique identification features set it apart from passive ID bracelets, making it a powerful tool in protecting vulnerable individuals.
