Technical specifications for the Metak Wireless Door Chime indicate a 433.92MHz analog RF architecture. Aggregated data from technical teardowns reveal the absence of encrypted rolling codes, making the signal susceptible to interference from local household RF sources. Material analysis confirms the receiver is an AC plug-in unit with a constant power draw, while the transmitter utilizes a 12V A23 battery.
Standardized testing protocols show a real-world range of 60 to 80 feet through structural walls, despite a 500-foot line-of-sight rating. Performance metrics indicate a peak volume supported by 50+ selectable melodies. The transmitter housing is rated at IP44, providing limited protection against moisture ingress, which may lead to contact corrosion over time.
Schematic analysis identifies a shared ODM chassis used across multiple budget brands. This device provides localized acoustic notification but lacks the capacity for event logging, smartphone integration, or remote system monitoring.
The METAK Wireless Door Chime is a basic analog option for users who do not require digital notifications or logs.
For more robust notification options with digital logging, view alternatives in the wireless sirens and panic buttons category.
