  • Doorbell camera test tool
    Patent number: 10180452
    Abstract: A test tool for a low voltage devices is described. The test tool comprises a voltage sensor, a current sensor, a diode sensor, a testing module, and an indicator. The voltage sensor determines a voltage between a first and second electrical wire from an alternating current (AC) transformer. The current sensor determines a current between the first and second electrical wires. The diode sensor determines a presence of a diode connected to the first and second electrical wires based on the current and the voltage. The testing module identifies one or more installation diagnostics related to a device to be coupled with the AC transformer. The indicator generates a visual or audible indicator corresponding to the one or more installation diagnostics.
