CENTSYS’s NOVA Code-hopping Remote Control. Fixed-coded remote systems – particularly those using dipswitches to set the code, are very easy to copy or clone. They also offer a very limited number of possible codes. In other words, these systems only provide convenience, with very limited security. CENTSYS’s solution? The award-winning NOVA remote controls offer code-hopping technology. Each code that is transmitted by the remote is totally and randomly different to the last code transmitted. This prevents unwanted copying of the remote signal and cloning of the remote itself. CENTSYS NOVA remote controls offers the same level of security as currently provided by leading brand automobile manufacturers for immobilising vehicle alarms and activating door locks.
