Vandal-Resistant Industrial Telephone
Analog | SIP | 4G
LC202-KB is heavy-duty industrial telephone engineered for locations where vandalism, noise, and harsh environmental conditions make standard communication unreliable. Built to remain operational at all times, this phone ensures that critical voice communication is never compromised.
Who is it for?
Designed for organizations operating in high-risk public and industrial environments such as parking facilities, prisons, airports, rail and metro stations, hospitals, police stations, shopping malls, stadiums, and other unattended or exposed locations.
The problem it solves
In vandal-prone and noisy areas, communication devices are often damaged, disabled, or rendered unusable. This telephone eliminates downtime and repair costs by providing secure, always-available communication, even under deliberate abuse or extreme operating conditions.
Why choose this phone?
High resistance to vandalism and abuse
Clear, loud voice communication without feedback
Reliable operation in extreme weather and temperatures
Simple installation with minimal infrastructure requirements
Long service life with MTBF exceeding 50,000 hours
