Keytroller's Seetroller digital wireless camera viewing device helps improve the safety and security of forklifts and equipment. The camera features FHSS technology (Frequency Hopping Spread Spectrum) which uses a channel hopping sequence based on an algorithm generated by the LCD display receiver. The strength of the signal being transmitted is set to be from 13.5-16dBm, which is much higher than the analog transmission signal allowed by authorities around the globe. Simply put, this means a much sharper and clearer picture, much longer transmission range and not susceptible to interference from machinery and microwave "noise."
