A remote monitoring system for telecommunication enclosures includes a low profile or flush mounted sealed transceiver or antenna unit, an electronic module inside of the enclosure electrically connected to the transceiver and a communication device to send signals to the electronic module through the transceiver. The sealed housing generally comprises a portion extending through the exterior surface of the enclosure. In some embodiments, the transceiver may include a radio frequency antenna, a photoelectric cell, a light sensor or an infrared sensor, and the communication device may be a handheld device, a transponder, or a networked computer.
