Why seal a tracker?
Most tampering is simple: a pulled power connector, a loosened antenna, a removed SIM or SD card. A numbered seal does not stop it. It shows that it happened, and the number tells you which part and since when. A register turns those numbers into a list you can check and audit.
Where should the seals go?
- The device housing, across the joint of the case.
- The power and ground connector at the device.
- The antenna connectors, GNSS and cellular.
- The SD card slot and the SIM slot of a recorder or tracker.
- Harness junctions and the CAN or OBD tap point.
- The fuse holder of the device feed, and sensor heads such as a fuel probe.
How does the status work?
The next inspection is the later of the fitting date and the last inspection, plus the interval in Settings. The interval ships as 30 days, a typical value you should replace with your own visit plan.
What goes in a broken-seal event?
Not every broken seal is tampering. A workshop may need to swap a SIM or reach a fuse. So each event asks two questions: was the work authorized, with a job card number, and what did the device record at that time? Authorized breaks are classed as such. A No becomes Unauthorized: investigate. A Not known becomes Check: work not confirmed.
Match seals with the device data
A seal tells you something was opened. The device data tells you when. Look for a main-power cut, a tamper alarm or a gap in positions around the time the seal broke. Tracom devices are built with tamper-proof security features, and your platform shows which alarms each model sends.
Limits
The register records seals and checks. It does not prove who broke a seal, and it is not a security standard. The interval, the window and the reorder level are typical values. Seal types and their strength depend on the product you buy.
