WIRELESS SMART DOORBELL SOLUTION WITH OPTIMAL PRICE

The smart wireless doorbell solution is fully provided by EPI Vietnam Technologies with electronic components integrated with modern technology. 

Smart wireless doorbells are becoming a trend in modern households. With a sophisticated design and Wi-Fi connectivity, the device allows users to receive notifications as soon as someone comes to the door, no matter where they are.  

The wireless doorbell solution from EPI uses the BC2161 chip, which is a transmitter with a frequency below 1Ghz and integrates the MCU BC66F2542 encoder for low power consumption. Solution with current consumption of only 3.2mA in the 433 MHz band and high sensitivity of -106 dBm at data rates from 1~10ksps.  

 Additionally, the simple wireless design facilitates installation and is capable of operating from a range of several hundred meters. Radio waves in the device help transmit signals with a maximum transmission power of 13 dBm.   

 EPI wants to find smart doorbell solutions that bring convenience and security when used. At EPI Vietnam Technologies, we provide full samples of component brands serving smart wireless doorbell solutions such as Holtek, Recom, HTC, etc.
