Wirless access control products and systems provide security to a wide variety of different kinds of organizations – large, medium-sized and small. Wherever they are installed, your products and systems ensure that the right people always have access to the right places at the right times, and that the wrong people never do.
While security is of utmost importance, the systems have been designed to provide a high level of convenience to install, use and maintain. The systems are both flexible and scalable, which means it’s easy to modify or expand them at any time to meet changing needs.
Whatever a customer's needs might be – from providing security at a single door to overcoming the security challenges faced by very large multinational corporations with thousands of doors and cardholders at different locations around the world.
User advantages
1) Installation is simple; the decoration does not destroy the environment.
2) Construction time is short, does not affect the normal working hours
3) System more stable, more secure data
4) Facilitate the migration of the late increase in equipment and equipment
5) Easier system maintenance, manufacturers can extend the time for maintenance-free

Contractors using advantages
1) Removed from communications wire and related construction costs
2) Shorter construction time, reduce labor costs
3) Maintenance is simple, do not check the lines, through the management software can find the problem.
4) Software is very user-friendly, it's easy to use, the manufacturers also provide personnel on-site training services, system functions can be modified by the owner required to fully meet the construction needs
5) System installation process eliminates the need for a large number of connections and ports, to reduce problems such as bad, manufacturers provide product warranty for two years.
6) No longer worry about the decoration of the scene, whether newly installed or equipment replacement projects to upgrade project, replacing a large number of on-site construction problems.
7) Facilitate the migration of the late increase in equipment and equipment
8) Many engineering companies have encountered the case of access control communications chip destroyed, most manufacturers will blame the switching power supply, of course, the high frequency current switching power supply will have serious impact on the chip, but requires the construction of conditions can cause a problem, is the power lines and communication lines more freely near (within 1 meter) or multi-core cable, so there is no connection with the electricity meter can be a constant line of communication to the current and voltage, which is the main cause communication chip burned, the practical application of , often not immediately destroyed, because the current and voltage is not big enough, has to do with protection circuit chip manufacturers, but the risk is that sooner or later go wrong. If you are willing to buy very good shielded cable, the problem is avoided, but a good access control system than the price of wire rod prices much higher. The wireless technology can solve this problem perfectly.
