Wireless network doorbell BULIK II PRO Type: DRS-995 SUN10000432

230V wireless network doorbell.
BULIK II PRO is the most advanced version of the BULIK II bell. The PRO version uses the most modern LoRa radio system, thanks to which the bell has the largest operating range in the world, up to 1400m in the open area! Such stringent parameters allow it to work without problems in conditions where ordinary wireless bells do not have a chance to maintain communication (large distance between the transmitter and the receiver, very dense buildings, thick walls, a large number of walls in the building on the way between the transmitter and receiver, etc.) . An additional advantage of the BULIK II PRO is the ability to upload any sound in MP3 format using a memory card.
