Mounting Two 3?8'' mounting slots Operating Temperature -40 to 75 degrees C/-40 to 167 degrees F Environmental NEMA TS-2 (see spec sheet download) The NITEK Etherstretch(TM) ET1500C IP cameras over Coax network extender Transmitter unit, is a network extender-PoE Inserter component. The ET1500C operates with either an ER8500C or ER16500C 8 or 16 Port IP Extender/Gigabit PoE Switch Receiver Unit, to form a multi-channel IP extender ''over-coax'' system. The System transmits IP cameras over coax and can quickly turn any ordinary RG59U coaxial cable into a high speed network communication & PoE path. When operating over RG59U coaxial cable, the coax network extender system can operate for distances of up to 500 meters (1,640 feet). ET1500C Transmitter is part of a system that operates in conjunction with either a ER8500C Eight Port Receiver or ER16500C Sixteen Port Receiver (these receivers are sold separately).The ET1500C coax ethernet extender requires very little installation time & absolutely no set up or configuration. The The ET1500C ethernet over coax network extender transmitter is transparent to the network and has no IP or MAC addressing. Simply connect your network devices to the network ports of the transmitter along with existing cabling and the system begins communicating. LED indicators show the status of network communication and PoE power.
