What are Pythons detectors: 

Python detectors are a radio frequency power detector and will provide an audio and visual alert when it detects an emergency service transmitted radio frequency signal.

Our Python detectors operates in the radio frequency range of 380-385 MHz which is used in a number of countries by the emergency services.

Our detectors will provide you a warning when it receives a transmitted signal from an emergency services vehicle.

"Our detectors will also help to ensure speed awareness. The warning alert from the Python Detector is especially useful to remind the driver keep to the speed limit"

Python detectors are a passive detector and do not provide any transmitted radio frequency signal and therefore cannot be detected by other emergency service vehicles.

Python detectors do not provide radio frequency signal demodulation and does not recover any received information content from a modulated radio frequency signal.

 
 

The detectors will detect signals from all directions (360 degrees). The detectors will automatically provide you with real-time feedback when it detects an emergency service transmitted radio frequency signal from an emergency service vehicle by providing:

  • Visual alert
  • Audio alert

If within detection range the detectors will detect stationary, mobile and emergency services vehicles that may be nearby but not be in your direct line of sight, these include:

  • Ambulances
  • Fire engines
  • Police cars


 

 Why Add Python to your existing RADAR or LIDAR system:

Python Detectors are not RADAR or LIDAR Detectors. Python Detectors do not rely on RADAR or LIDAR targeting to alert the driver of approaching, nearly hidden or hidden Emergency Services Vehicles.Python is a R.F.P.D Detector meaning a Radio Frequency Power Detector and will provide the driver an audio and visual alert when it detects an transmitted radio frequency signal in the frequency band 380-385 MHz. This frequency band is specifically allocated for emergency services radios which use the TETRA standard in the UK.

Python Detectors will provide a warning alert when they detect a transmitted signal from the Radio of an Emergency Services Vehicle. The Emergency Service Vehicles Radios constantly transmit their location to the network and the Python Detectors will detect these transmissions. This means that a Python Detector can register a detection from Emergency Service Vehicles which may not be involved in speed awareness detection and which are not in your direct line of sight.


 The Visual Alert: 

The visual display is located at the front of the detector and allows the visual alerts to be seen in your peripheral vision: The number of blue LEDs shown on the visual display will indicate the strength of the detected signal. A strong signal would indicate that an emergency services vehicle is very close to you and on the visual display would show:

  • 4 to 5 warning LEDs

A weaker signal would indicate that an emergency services vehicle is further away from you and the visual display would show:

  • 1 to 3 warning LEDs
 

Python P1, P2 & P2/IB Visual Display:

The blue LEDs on the Python P1, P2 and P2/IB visual display will remain ON for 3 seconds after detection, if there is no further detected signals the LEDs will slowly turn off one-by-one until all LEDs on the visual display are OFF.  

strength of the detected signal at each display levels. 

BST: 

The Python P2 has an options "Power Booster Module", and when fitted to your detector the green BST LED will be shown on the visual display indicating that the power booster is now active. Once fitted the power booster module will set your detector sensitivity level automatically to boost sensitivity level 6 and the sensitivity setting buttons are disabled.

The Python P2/IB has an Integrated Power Booster Module, and is always active and detector sensitivity can also be adjusted to 5 different levels to suit the surrounding topology. 

Note: The BST mode is not available with the Python P1.

Python P3 Visual Display:

The blue LEDs on the Python P3 visual display has our “variable brightness adaption” that allows for improved visual display of a detected emergency service signal.
When the detector detects a signal it will display this as a number of blue LEDs. Each LED can be illuminated at 4 different intensity levels indicating the strength of the detected signal at each display levels. 

MDA: 

The visual display has a unique “Multiple Detection Alert” feature (MDA) that will tell you if a number of alerts have been received in a short space of time.
The “Multiple Detection Alert” will be illuminated when 3 separate emergency service signals are detected within 45 seconds.
When the MDA feature is in operation the green LED on the visual display will be illuminated for 45 seconds reminding you that Emergency Service Vehicles may still be operating in the surrounding area.

Optional Python P3 Remote Display Header (Available February 2019):

The Optional Remote Display Header is compatible with your Python P3 detector and connects to the expansion port on your detector via our interface cable. The Remote Display Header allows you to mount the small Visual Display in a different location than the main Python Detector Unit.

The Remote Display Header has 6 coloured LEDs indicating the following:

  • Power: ON/OFF
  • Sensitivity: Level 1 to Level 5

The Remote Display Header will be activated after connecting the interface cable to the expansion port on the main Python Detector Unit and main Detector Unit power button has been turned ON.

 Visual Display Brightness: 

You can adjust the visual display brightness to ensure that the display does not distract you from safe control of your vehicle. All Python Detectors are fitted with a variable brightness control that can be adjusted to a number of different settings. The variable brightness control has a number of different levels.  

 

 Dark Mode: 

The Python detectors are a passive detector and do not provide any transmitted radio frequency signal and therefore cannot be detected by other emergency service vehicles.

However for travelling at night you may want to reduce the visibility of your detector.

With our Python P2, P2/IB and P3 detectors we have a feature called Dark Mode, where you can now switch off both visual display and the user interface to OFF so the detector will not be so visible at night:

0 = Display OFF

through to:

Dark Mode = User Interface OFF 

Note: The Dark Mode is not available with the Python P1.


 The Audible Alert: 

The audible alert is located on the underside of the detectors. When the detector detects a signal it will sound the audio alert once warning you that:

  • There is an accident and emergency services vehicles may be operating
  • Emergency services vehicles may be nearby but not be in your direct line of of sight.
  • You may be approaching a stationary emergency services vehicle that may not be in your direct line of sight.
 

 Audible Alert Summary Table: 

The audible alert is a series of short bleeps which indicate the strength of the detected signal. The number of bleeps also corresponds to the number of blue LEDs presented on the visual display. The advantage of the audio alert is that it provides you with a real-time warning without the need to look at the visual display and thus ensuring safe control of your vehicle.
 

Python P1 can be adjusted to 2 different settings:

0 = Alert OFF

1 = Alert ON (No Repeat)


Python P2 and P2/IB detectors we have introduced 2 additional Alert Repeat Modes, this has the advantage to provide you with a repeated audible alert warning when emergency services vehicles are nearby and still being detected:

     2 = Audible Alert ON (Repeat 8 seconds)

     3 = Audible Alert ON (Repeat 12 seconds)


Python P3 detector we have introduced a further 2 Alert Repeat Modes: 

     4 = Audible Alert ON (Repeat 3 seconds)

     5 = Audible Alert ON (Repeat 6 seconds)




 The Detection Range: 

The detection range of the Python detectors depends on a number of factors such as:

  • The strength of the transmitted signal received by the detector
  • The distance from the transmitted signal from the detector
  • The surrounding terrain

The detectors detection range can be increased by ensuring you have the sensitivity setting set to the highest level.    

 

The detectors detection range can be increased by ensuring you have the sensitivity setting set to the highest level.   


 Motorways: 

In an open environment such as a motorway where there is a relatively flat and open topology the detection range may be greater.

 City: 

In an urban environment where tall buildings or other topology may block the transmitted RF signal to the detector range may be decreasted. 


 Detection Sensitivity:

The detection sensitivity can be adjusted to a number of different settings to allow for different driving, topology and environmental conditions:

  • Python P1 has 3 sensitivity levels
  • Python P2 has 5 sensitivity levels 
  • Python P2 with optional Power Booster Module is set to level 6

Note: The sensitivity levels on the Python P2 CAN NOT be adjusted while in Booster mode. 

  • The Python P2/IB and P3 have 5 sensitivity levels

Note: The Python P2/IB and Python P3 detector sensitivity at level 5 is MORE sensitive than level 6 on our standard Python P2 detector and CAN also be adjusted in all levels while in boost mode to suit the surrounding topology and environmental conditions.


 Detection Summary Table: 

The following tables provide a quick summary of the approximate detection ranges of the Python detectors depending on the environmental conditions and different upgrade options and model type.

 

Python P1: 

The detection range of the P1 detector can by increased by approximately 50% by adding an optional Higher Gain RF Antenna:

  • Higher Gain RF Antenna (~50% improvement)
 

Python P2: 

The detection range of the P2 detector can be increased by upgrading with any of the following options:

  • Power Booster Module (~25% improvement)
  • Higher Gain RF Antenna (~50% improvement)

You can also use the Power Booster Module and Higher Gain RF Antenna together to ensure the greatest detection range:

  • No need for Optional Power Booster Module
  • Python P2/IB and Python P3 have an Integrated Power Booster (~40% improvement)
  • Integrated Power Booster is always ON (active)
  • Sensitivity CAN be adjusted in all levels while in Booster Mode

You can also use the Python P2/IB or Python P3 detectors and Higher RF Gain Antenna together to ensure the greatest detection range:

  • Higher Gain RF Antenna (~100% improvement) 

Note: The Python P2/IB and Python P3 figures are compared to a Standard P2 (without the Optional Power Booster Module fitted) and compared in Open Terrain with 600 meters detection range.

 

Note: The detection range of the Python detectors depends on a number of factors such as the strength of the transmitted signal received by the detector, the distance from the transmitted signal from the detector and the surrounding terrain. The figures quoted are calculated examples based on different road and environmental topology.
