THINKWARE TWA-SH is a hardwiring cable that connects the THINKWARE dash camera directly to your vehicle’s fuse panel, which allows the camera’s parking surveillance mode to function while the vehicle’s ignition is turned off. The built-in voltmeter in the main dash cam unit will be activated to monitor the battery level. The dash cam will automatically shut off if the voltage dips below the configurable voltage cut-off level. | THINKWARE Hardwiring Cable for THINKWARE Dash Cams (TWA-SH)
