This product adopt the technology of infrared pyroelectric principle tosense human activity information. When someone enters the induction range, it can accurately identify the human activities. It looks like a cat's eyes, not depending on light. Even in the dark environment, it can work stably and reliably, overcoming the shortcomings of light induction.It is small and exquisite, easy to carry and has a beautiful sound. With the human body induction trigger, it has wide induction range, sensitive trigger, intelligent triggering, no need to have manual operation. One of the main characteristics is using our company’s mature human body induction technology. When detecting the human body passing it will give warm prompts, warnings and welcomes at the first time. According to the differen...
SmartBell combines the technology of wireless remote control door bell and human body induction, more flexible, a good advantage over ordinary doorbell. It is available to replace doorbell audio through micro SD card and have another function of human body induction. It is placed near the door. When people enter the induction range, SmartBell can accurately identify, detect and have passive sensing of human activities, then play voice. Like cat's eyes, it is not depending on the light, can work stably and reliably in the dark environment, overcoming the shortcomings of light induction. Human body induction function can also be shielded, retaining only the wireless doorbell function
