Technical specifications indicate that the Tmezon 7-Inch system utilizes a 4-core physical connection protocol (V+/V-/Audio/Video) for signal transmission. Aggregated specification data lists a 1200TVL CMOS sensor in the outdoor unit and a 7-inch TFT LCD monitor for the indoor interface. The outdoor module is constructed from IP65-rated aluminum alloy, which provides superior environmental protection compared to polycarbonate alternatives.
Performance metrics demonstrate that the system supports a point-to-point analog/digital hybrid signal path, ensuring instant-on video with no network buffering. The internal circuitry supports an expansion of up to two outdoor doorbells and four indoor monitors. Material analysis reveals the use of a resistive touch interface on the monitor, designed for durability in various indoor environments.
Standardized testing protocols show that signal degradation occurs if standard thin-gauge bell wire is used for runs over 50 meters. The use of RVV4 or Cat5e with appropriate baluns is required to maintain video voltage stability and prevent display ghosting.
The Tmezon 7-Inch Wired Video Intercom System serves as a stable alternative for users prioritizing offline privacy, while those needing remote mobile alerts should consider the TP-Link Tapo D225 for its integrated Wi-Fi stack.
This unit is classified under wired video doorbell systems, specializing in closed-loop signal propagation.
