Helmer LK 503


The miniature locator on the pendant allows tracking and locating objects specifying the exact GPS position and the subsequent submission of information and coordinates via SMS to a preset number or via GPRS to the computer. It is therefore necessary to insert a prepaid SIM card or a SIM card with a data plan into the locator to get an instant overview of the location of the object.

This information will send you the Helmer LK 503 to your phone in the form of an SMS message, which is not only quick and efficient, but also cheap. The second method is data rate tracking, where the locator sends the detailed information to a particular server at the time you selected, which you can later edit. Specific settings for additional features, such as bidirectional communication, can be done with a special SMS format (see the enclosed manual for its exact form).

Other functions:

  • Listening - after the call, you can hear the sounds around the locator
  • SOS call - Pressing the emergency key will call the preset phone numbers
  • Password settings - communication with the locator can be secured and set up so that the information is sent only to a selected phone number
  • Motion alert - if the locator moves to a distance that wasn't predetermined , it sends you an SMS warning
  • Geo-Fence locking - With this feature, you can restrict the locator's movement to the specified area (if you leave it again, you will receive a message)
  • You will receive a warning when exceeding the preset speed and a low battery level
