It serves as the central communication hub in a JM-series intercom system, handling both handset (duplex) and hands-free VOX communication modes. The unit supports up to 4 door stations and 7 sub master stations simultaneously. Pan-tilt-zoom (PTZ) and brightness controls give the installer and end user direct command over door station camera angle and lighting. This station is installed by low-voltage electricians and security technicians in residential and light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThe jm-4med-u fits intercom systems where centralized visitor management is required. Every inside station in the network includes a door release button for controlled entry. Picture memory captures and stores up to 20 calls to internal memory and up to 1,000 calls to a removable SD or SDHC card, which is not included with the unit. The station connects to door stations via 18AWG 2-conductor cable and links to sub master stations over CAT-5e or CAT-6 cable, making it compatible with standard low-voltage structured wiring practices.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-inch color touchscreen LCD for clear video monitoring of door stations\u003c\/li\u003e\n  \u003cli\u003eSupports handset (duplex) and hands-free VOX communication modes\u003c\/li\u003e\n  \u003cli\u003eConnects up to 4 door stations and 7 sub master stations\u003c\/li\u003e\n  \u003cli\u003ePTZ and brightness controls for camera angle and lighting adjustment\u003c\/li\u003e\n  \u003cli\u003ePicture memory stores up to 20 calls internally and 1,000 calls to SD or SDHC card\u003c\/li\u003e\n  \u003cli\u003eDoor release button on all inside stations for visitor entry control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConnects to door stations using 18AWG 2-conductor cable and to sub master stations using CAT-5e or CAT-6 cable within the JM-series intercom system.
