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:

"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 sight"

"You may be approaching stationary emergency services vehicle not in your direct line of sight"

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

After detection, each warning LED will remains ON for 3 seconds. 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.

 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. The visual display is 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 P2 and P2/IB detectors we have introduced a new 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


 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.

The audible alert on the Python P1 can be adjusted to 2 different settings:

0 = Alert OFF

1 = Alert ON (No Repeat)

With our P2 and P2/IB detectors we have introduced 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 = Alert ON (Repeat Slow)

     3 = Alert ON (Repeat Fast)


 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.


 
 

 Motorways: 

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

 City: 

In an urban environment where tall buildings or other topology may block the signal to the detector and the detection range is decreased.




 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 (and can be set to level 6 with our optional Python P2 Power Booster Module)

The sensitivity levels on the Python P2 CAN NOT be adjusted while in Booster mode. Refer to Python P2/IB for this new feature.

  • The Python P2/IB has 5 sensitivity levels

Note: The Python P2/IB 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 the Higher RF Gain Antenna:

  • Higher RF Gain 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)
  • Sensitivity levels CAN NOT be adjusted while in Booster mode
  • Higher RF Gain Antenna (~50% improvement)

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

  • Higher RF Gain Antenna and Power Booster Module (~75% improvement)

Note: The Python P2 figures are compared to a Standard P2 and compared in Open Terrain with 600 meters detection range.

 

Python P2/IB: 

Our Python detector P2/IB has enhanced functionality to allow for the Power Booster to be integrated into the detector to provide increased sensitivity and improved detection range over the standard Python P2 Detector:

  • No need for Optional Power Booster Module
  • P2/IB has 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 detector P2/IB and Higher RF Gain Antenna together to ensure the greatest detection range:

  • Higher RF Gain Antenna (~100% improvement) 

Note: The Python P2/IB 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.
