Viano OS2 Car Rodent Repeller with Ultrasonic Speakers 200m Range
Description
VIANO Automotive Rodent and Marten Repeller
VIANO OS2 Automotive Rodent Repeller is a proven solution protecting the engine compartment against martens, mice, rats and weasels. The device equipped with two efficient piezoelectric speakers emits ultrasound with variable frequency, preventing pests from becoming accustomed to the signal.

Intelligent automation sets the VIANO OS2 apart from the competition. The device automatically switches off when the engine starts and reactivates when it is turned off. This means you don't have to remember any switches – protection is always active when the vehicle is stationary.
Minimal power consumption of just 15 mA allows the device to operate for up to 5 months without risk of draining a healthy battery. This is an ideal solution for vehicles used seasonally or less frequently.
Key advantages
- Effective protection: works against martens, mice, rats and weasels
- Wide coverage: ultrasound emission up to 200 m at 120° angle
- Automation: automatic on/off depending on engine operation
- Safety: fuse socket protecting against short circuit
- Pet-friendly: signals outside the hearing range of dogs and cats
Simple installation in minutes
Installation involves connecting two 90 cm wires terminated with ring connectors under the battery terminal screws. Red wire to positive, blue to negative – that's all. The mounting bracket allows stable fixing of the device in the engine compartment.



Durability in harsh conditions
The device uses brass piezoelectric speakers protected by special covers. This makes them resistant to moisture, extreme temperatures and accidental spillage of operating fluids. Unlike ordinary membrane speakers, which quickly become damaged, VIANO OS2 components ensure long-lasting and trouble-free operation.
