I am pleased to introduce our products of wireless door phones and wireless audio access systems. These products have the functions of wireless intercom and remotely opening door. Communication range between Base and Handset is up to 100 meters (GP-MA400) and more than 300 meters (GP-MA600) in free range space. They overcome the limitation of the wireless doorbells and access control systems which can not talk, can not open door remotely, and avoid the trouble of run cables indoor. A system is fully expandable up to maximum of 4 Handsets. They are update substitutes for the traditional doorbells and access control systems. They are suitable used in offices, houses, villas, or tier buildings. These products are patent products in China and have got CE certificate. They have exported to Europe and Africa. We are willing to make faithful cooperation and establish long-term business relationship with international trade company, wholesaler, importer, or distributor.
