backward movement.
Advanced Activity Sensor
measures activity on three axes based on the
true
acceleration
experienced by the collar (Figure below). There are 3 axes (X, Y, Z) which
constitute a three-dimensional space in which acceleration is measured. Data can be
stored as true acceleration raw data generating a massive amount of information. The
sensor records data with 2, 4, 8, 16 or 32 Hz (measurements per second). The default
mode is 8 Hz. The memory capacity depends on sampling rate (e.g. up to 5 years with 8
Hz). The raw data is detailed enough to not only observe general pattern but to
distinguish distinct behaviors and get a clear picture on what the animal is doing with
proper analysis.

NOTE
: Activity raw data can only be downloaded via USB to VERTEX Plus Interface
cable because of the massive amount of data (Not via satellite, GSM or UHF
communication!)

Proximity and Separation Sensor
The proximity sensor is part of a system that enables you to monitor interactions
between different animals such as predator and prey or encounters between individuals
of different social groups. The proximity sensor in the VERTEX Plus Collar with UHF
communication is able to receive ID codes within a range between 5 and 500 meters,
depending on ID Tag, collar settings and environmental issues.
If an ID code is received, it will be stored in the memory with the signal strength and the
time stamp. If GSM or Iridium transmission is enabled, a list of ID codes encountered
between two transmissions is sent with each GSM or Iridium message. Signal strength
and time stamp are not transmitted via GSM or Iridium. These are only available via
cable or UHF link. The file extension is .PRX.
