A secure tracking and monitoring device, wearable on a wrist, the device comprising:
- a watch;
- a first band comprising a first end and an opposite, second end, with the first end of the first band attached to said watch;
- a second band comprising a first end and an opposite, second end, with a first end of the second band attached to said watch;
- a biometric locking device comprising one or more biometric sensors configured to detect a biometric characteristic of a subject and responsively generate a biometric input, and one or more locking actuators configured to selectively adopt a locked position in which the one or more locking actuators disconnectably attach the second end of the first band to the second end of the second band and an unlocked position in which the one or more locking actuators do not attach the second end of the first band to the second end of the second band, wherein the one or more biometric sensors comprise at least one biometric sensor at the second end of the second band;
- and
- at least one controller comprising at least one processor and at least one memory, wherein the at least one memory stores processor-executable instructions configured to cause the at least one processor to execute the operations of:
- receiving a biometric input generated by the one or more biometric sensors;
- comparing said received biometric input with a specific biometric input stored in the memory, said specific biometric input corresponding to an authorized subject;
- and
- if said received biometric input matches said specific biometric input, operating said one or more locking actuators to switch between the locked position and the unlocked position;
- and further wherein
- the watch comprises:
- a first plurality of cameras and a first plurality of lights disposed in spaced-apart relationship about a periphery of the watch, each light of the first plurality of lights arranged between a respective pair of adjacent cameras of the first plurality of cameras, and
- a second plurality of cameras and a second plurality of lights disposed in spaced-apart relationship about a periphery of the watch, each light of the second plurality of lights arranged between a respective pair of adjacent cameras of the second plurality of cameras, wherein
- the second plurality of lights and second plurality of cameras are arranged in vertical alignment and below the first plurality of lights and first plurality of cameras, respectively, and further wherein the first plurality of cameras are oriented upward and radially outward of the watch and the second plurality of cameras are oriented radially outward of the watch.
