## Common ground
All options are types of tracking or monitoring devices that detect, locate, or follow objects or individuals.
## Options at a glance
**8517.62 – Bluetooth/UWB tracking tags**
- **Defining trait:** Uses Bluetooth or ultra-wide band (UWB) to connect with smartphones or Find My networks for real-time location of personal items.
- **Typical examples:** Tile, Apple AirTag, Samsung SmartTag.
- **Best fit when:** Tracking small, portable items like keys, bags, or bikes using consumer-grade wireless networks.
**8523.52 – Animal tracking smart cards**
- **Defining trait:** Designed specifically for animal identification and location via embedded smart card technology (e.g., RFID).
- **Typical examples:** Microchips implanted in pets, livestock tracking tags.
- **Best fit when:** Monitoring animals (pets, farm animals) using passive or low-power RFID systems.
**8526.91 – Position determination devices**
- **Defining trait:** Uses GPS or other satellite systems to determine geographic position, often without real-time network connectivity.
- **Typical examples:** GPS trackers in vehicles, hiking watches, marine navigation devices.
- **Best fit when:** Determining location in remote areas or for long-range, autonomous positioning.
**8531.80 – Bluetooth/Radio frequency tracking devices**
- **Defining trait:** General-purpose RF or Bluetooth-based tracking devices not tied to a specific network (e.g., Find My).
- **Typical examples:** DIY trackers, industrial asset monitors, generic beacons.
- **Best fit when:** Custom or non-consumer applications requiring flexible wireless communication.
**video surveillance systems**
- **Defining trait:** Captures and records visual data for monitoring; location tracking is indirect (via video analysis).
- **Typical examples:** CCTV cameras, IP security cameras with motion detection.
- **Best fit when:** Visual observation and recording are primary goals, not real-time object tracking.
**baby monitoring devices**
- **Defining trait:** Monitors infant activity (sound, movement) via audio/video or sensors; location tracking is not the core function.
- **Typical examples:** Audio baby monitors, video monitors with temperature sensors.
- **Best fit when:** Parental supervision of a child’s well-being in a fixed location.
## Key differences
| Option | Core Technology | Primary Use Case | Network Dependency | Mobility Focus |
|-------|------------------|-------------------|--------------------|----------------|
| 8517.62 | Bluetooth/UWB | Personal item tracking | High (Find My) | High |
| 8523.52 | RFID smart card | Animal ID/tracking | Low | Medium |
| 8526.91 | GPS/satellite | Positioning in open areas | Medium | High |
| 8531.80 | Bluetooth/RF | General tracking | Variable | Medium |
| video surveillance systems | Video capture | Visual monitoring | Low | Low |
| baby monitoring devices | Audio/video/sensors | Infant care | Medium | Low |
## How to choose
- Does it track small personal items using a smartphone network? → 8517.62
- Is it implanted or used for animals with RFID? → 8523.52
- Does it use GPS for outdoor location without relying on phones? → 8526.91
- Is it a general-purpose RF/Bluetooth tracker for non-consumer use? → 8531.80
- Does it capture video/audio for observation, not tracking? → video surveillance systems
- Is its main purpose monitoring a baby’s presence or activity? → baby monitoring devices
## Overlaps & pitfalls
- **Overlaps:** A device with GPS and Bluetooth (e.g., a pet tracker) could fit both 8526.91 and 8531.80.
- **Pitfalls:** "Tracking" in video systems is indirect; don’t confuse surveillance with real-time location tracking.
- **Priority rule:** If multiple options apply, choose based on the product’s MAIN function—e.g., if it’s for visual monitoring, pick video surveillance, even if it has some tracking features
