Yes. The RG59 BNC cables and Cat5e Ethernet cables that Ansjer provides are both in-wall rated and fire resistant.
More specifically, our cables meet the standards for CMR (Riser) cabling. This means that they can be used between walls and between floors, so long as these areas do not circulate environmental air for heating or conditioning systems. Our cables also pass a vertical burn test that ensures flames will not travel along the cable in the case of a fire.
