Viano King-LED OD16 Rodent Repeller for Martens, Mice and Rats
Description
VIANO KING-LED 24V – professional rodent, marten, mouse and rat repeller
VIANO KING-LED 24V is the largest and most powerful ultrasonic repeller available on the market, designed to provide effective protection against martens, weasels, mice and rats. The 24V DC version has been created for integration with photovoltaic installations and low-voltage power systems.

The device combines exceptional sound power with an intense visual effect, guaranteeing the highest level of effectiveness. Thanks to the use of four professional piezoelectric speakers and four very bright LED diodes, it creates an environment that pests simply cannot tolerate.
Construction and technology
The device features three large speakers with a diameter of 50 mm and one 35 mm speaker, ensuring a wide range of emitted frequencies and high impact force. Four flash LED diodes enhance the repelling effect – pests react to light pulses, avoiding the protected area. The LEDs can be switched off using the side button if the user wishes to use only the sound function.

Professional IP65 housing
The housing has been designed for harsh outdoor conditions – it is hermetic, robust and compliant with IP65 protection class. This allows the KING-LED to be used both indoors and outdoors. The housing features a silicone seal, durable mounting screws and a protected switch, preventing moisture and contaminants from entering.


Easy and universal installation
A strong neodymium magnet on the rear of the housing allows for quick attachment of the device to any metal surface – guttering, shelving, window sills or roof fittings. Additionally, the set includes a metal plate with mounting holes, enabling permanent screwing of the device to wood, concrete or other non-metallic surfaces.

Safety and durability
The device uses solid brass piezoelectric speakers, which are resistant to moisture, temperature changes and mechanical damage. Each is additionally protected by a grille. This significantly increases the device's lifespan compared to cheaper models with membrane speakers, which can cause short circuits and are easily damaged.
