Wireless Doorbell For Home, Pager Without Wiring, Long Distance.

The mini doorbell uses a receiver-based system for easy installation without disrupting the aesthetics of your home's decor. The electronic peephole supports remote control with a range of up to 20-30 meters (in open spaces). (Due to interference from metal surfaces, security doors, walls, and reinforcing bars, the typical range of a home remote control is approximately 15 meters.) This meets the needs of various residential and high-rise buildings. The multi-purpose outdoor doorbell transmitter requires a fixed position. It should be attached to the entrance or a rain-protected area with double-sided tape to prevent dripping. The smart doorbell is battery-operated: the receiver requires two AA batteries, and the transmitter requires one 23A battery (included). In static environments, neither the receiver nor the transmitter consumes power, and the batteries last for a year. Compact doorbell: Made of durable ABS material, this doorbell is very compact. Purchase includes: one receiver, one transmitter, one battery, and one double-sided sticker.
