马来西亚采购需求：智能锁，智能门锁，指纹锁应用程序，生物识别指纹锁，耶鲁智能锁，门指纹锁

I'm interested in exploring the pricing for both the purchase and installation of your smart door knob. Could you provide me with the cost details? Additionally, it would be helpful to know if there are any special features or options available that might affect the pricing. Also, please let me know about your installation services—do you offer on-site installation, and if so, what is the typical timeframe for completion? I'm keen to understand all aspects before making a decision. Thanks!
