RAPTOR Bird and Wild Animal repeller Systems
Imitation of natural predators
The high degree of effectiveness of the RAPTOR is due to the acoustic imitation of natural predators. The system uses a rotating random sequence of six to eight sounds from nature that the birds and other animals instinctively associate with danger. As a rule, when the animals hear these sounds they stay away from the protected areas.
Although humans can also hear the sounds, from a certain distance the sounds are not consciously registered since they mix with the naturally occurring sounds in the surroundings.
Through use of naturally occurring sounds, and also due to the good playback quality, the RAPTOR sounds very realistic. It is so realistic that some birds of prey may be attracted by the calls of birds of their species, or people may occasionally be drawn to search for the stray dog that they assumed to have heard.
Various sound chips are available to specifically match each the needs of each individual customer. These chips can also later be exchanged with different sound chips.
Directed sound
The RAPTOR uses speakers with pronounced directionality. Therefore, a very specific area can be targeted by the sounds and nearby residential areas can be avoided.
Natural noises, such as
sounds of birds of prey
dog bark
characteristic warning and alarm sounds
trigger the animals' inborn escape reflex. Birds and wild animals instinctively avoid the RAPTOR-sounded areas because they consider them dangerous.
These instinctive escape reactions are not expected to lead to habituation effects.
Set up, connect battery, READY !
The RAPTOR is quick and easy to assemble, which ensures high flexibility and can be used in different locations depending on seasonal requirements.
The sustainable power supply is provided by standard rechargeable 12V batteries.
A charge lasts up to several months.
The RAPTOR was developed on the basis of decades of experience and scientific knowledge.
The goal was to realize the bird and game defense as efficiently, environmentally friendly, sustainable and without habituation effects as possible.
The RAPTOR achieves this by:
Imitation of danger by reproduction of natural alarm noises (warning sounds of the species, calls of natural enemies, noises which signal danger)
different sound sets with 8 sounds each (2x8 for some models) which sound randomly and are available for different animal species.
High volume audible for birds, wildlife and humans.
Animals respond on an instinctive level.
a random time interval, the value adjustable by the controller varies by +/-20%.
an intelligent day/night automatic with 4 / 8 operating modes
the radio release function of the RAPTOR R56 remote.
Frequency range: A perfect fit
The frequency range of the RAPTOR (300-5100 Hz) has been optimised to match the hearing range and maximal sensitivity of birds and wild animals. The RAPTOR does not use any frequencies that lie outside of the detection range of birds, which is something important in view of noise control. Though it can be loud if a person stands directly in path of the RAPTOR device (up to 125dB /1m), if the low noise recommendations are followed, the sound can often go unnoticed.
In comparison with other methods:
Pyrotechnics: ("firing devices") emit sound at a very high level in a lower frequency range. This range is irrelevant for bird control since birds cannot hear sounds below 300Hz. People, however, can in fact hear sounds in this range and, since lower frequencies can travel further, can still hear these sounds multiple kilometres away from the source.
Ultrasound:Though ultrasound can be heard by mammals, birds have a much differently constructed middle ear that prevents them from hearing these sounds. Mere ultrasound is therefore unsuitable for bird control. The “ultrasound bird control systems” on the market that emit sounds above approximately 2kHz can also be heard by people. Also, since the frequency range only partially overlaps with the hearing range of birds, and since the higher frequencies have a small acoustic range, these devices are only moderately effective.
