One hardware platform. Two deployment paths.

The G608 series was designed for a category that doesn't have a standard name: a device that can track the location and vital signs of an elderly person with dementia, and then — with a strap change — do the same for a working dog on a farm.

This is not a marketing claim bolted onto a human device. The device is documented for both use cases from the start: a health positioning wristband for elderly care, and a pet tracker with vital sign monitoring. One hardware platform. Two deployment paths.

The architecture that makes this possible is simple: a 30-gram module with PPG health sensors, positioning radios, a 600mAh battery, and a standard 22mm strap fitting. Put it on a silicone wristband for an elderly relative. Swap to a nylon collar loop for a dog. The hardware does not change. The platform does not care whether the wearer is human or animal — vitals are vitals, location is location.

Health monitoring: what it tracks, and what the numbers actually mean

The G608 series carries a PPG photoelectric sensor module. It measures:

Positioning: four sources, seamless transitions

• GPS + BDS (BeiDou) — outdoor, open sky, 5-20m

• WiFi fingerprinting — suburban and urban, 10-50m depending on AP density

• Cellular LBS — fallback

• BLE 5.1 beacon scanning — indoor, 1-3m with 6-8m beacon density; sub-meter with AoA gateway

The device switches between sources automatically. A dementia patient walking from the garden (GPS) into the day room (BLE) is tracked across the transition. A dog running from the backyard into the house is continuously monitored. No action required from the wearer — human or animal.

Wear detection: the sensor that knows it's been removed

The G608 series uses dual-sensor wear detection: the optical heart rate sensor combined with the accelerometer. If the heart rate sensor loses contact AND the accelerometer reports no movement, the device concludes it has been removed.

• For elderly care: If a dementia patient removes the band at night, the caregiver is notified immediately — not during morning rounds.

• For pet tracking: If a dog slips its collar in the woods, the owner knows the moment it happens and sees the last known location.

Both "on" and "off" events are reported to the platform with timestamps. When off-body, the device drops into ultra-low-power mode, stretching standby beyond 20 days.

Two network variants

Choose G608G if: You need the simplest deployment — unbox, charge, and the device connects via cellular. The pre-installed 3-year IoT SIM works across mainland China. Regional SIM options available for international deployments.

Choose G608L if: You operate a private LoRaWAN gateway — a care home campus, a large kennel, a fenced sanctuary. Data stays on your infrastructure. No carrier dependency. Trade-off: no WiFi positioning, and coverage is limited to gateway range.

Battery and power management

The Cortex M4 + Cat.1 bis architecture keeps system idle current below 0.1mA. Motion-triggered reporting suppresses positioning when the wearer is stationary. Offline buffering via 1MB Flash stores data during signal loss.

Auto-on from charger: The device powers on automatically when removed from the magnetic charging cable. For an elderly person who forgets to press buttons, or for a pet that cannot press a button, this eliminates a common failure point — the device sitting on a charger, fully charged but powered off.

The 22mm strap ecosystem

The G608 series uses a standard 22mm watch strap fitting. This is a small detail with a large practical consequence:

For people:

• Default silicone strap included

• Optional velcro strap for arthritic hands

• Any standard 22mm watch band fits — leather, nylon, metal

For pets:

• Remove the silicone wrist strap

• Thread a collar loop or zip ties through the 22mm lug slots

• At 30 grams, comfortable for any dog over 5 kg and most adult cats

For livestock:

• Integrate into existing neck collars or ear tags

• IPX6 waterproofing handles rain, mud, and outdoor exposure

What the G608 series is NOT

Deployment scenarios

Elderly care with health monitoring:

A 78-year-old with mild cognitive impairment wears the G608G on a velcro strap. The caregiver's app receives location updates every 10 minutes and vital sign trends every hour. The wear detection sensor alerts if the band is removed unexpectedly. The SOS button triggers an immediate alert with GPS coordinates. The health dashboard shows a gradual heart rate increase over several weeks — flagged for discussion at the next checkup.

Pet health and location tracking:

A working farm dog wears the G608G on a collar. GPS tracks movement across pastures. The owner reviews daily step count and sleep data alongside location history. During summer, the temperature sensor provides early warning of heat stress before the dog shows visible fatigue. A gradual SpO2 decline over weeks prompts a vet visit that catches a respiratory issue early.

Dual deployment — human and pet, same platform:

A family uses G608G devices for both an elderly parent and a family dog. Both appear on the same cloud dashboard. The platform distinguishes them by device ID. Caregivers monitor the parent's location and vitals; family members check the dog's activity and location. One platform, one hardware, two completely different care scenarios.
