AXIS Q1755/-E - Unit connectors

Unit connectors

Network - RJ-45 Ethernet connector. Supports PoE (Power over Ethernet, class 3). Using shielded cables is recommended.

Audio in - 3.5mm input for a mono microphone, or a line-in mono signal (left channel is used from a stereo signal).

Audio out - 3.5mm output for audio (line level), can be connected to a public address (PA) system or an active speaker with a built-in amplifier. A pair of headphones can also be connected. A stereo connector must be used for audio out.

Video Out - RCA connectors for component or composite video out.

•Component video out (Y/Pb/Pr) for HDTV video, e.g. an entrance camera connected to an HDTV screen

•Composite video out (CVBS) - for easy installation using a video monitor

RS-485/422 - two 2-pin terminal blocks for RS-485/422 serial interface used to control auxiliary equipment, e.g. PT devices.

The RS-485/422 serial port can be configured as follows:					RS-485/422
	• Bidirectional RS-485 half-duplex port for data transmission using two wires, one combined
	RX/TX pair.

SD memory card slot - High capacity SD memory card can be used for local recording and removable storage.

Lens - M37x0.75 mounting thread for optional lens adaptor, for example wide-angle adaptor, tele adaptor or lens filter. Remove the existing lens cover and retain for future use. Attach the adaptor securely to the camera casing.

I/O terminal connector - Used in applications for e.g. motion detection, event triggering and alarm notifications. In addition to an auxiliary power and a GND pin, the AXIS Q1755/-E has 2 pins that can be configured as either input or output. These pins provide the interface to:

• Transistor output - For connecting external devices such as relays and LEDs. Connected devices can

be activated by AXIS VAPIX API, output buttons on the Live View page or by an Event Type. The output will show as active (shown under Events > Port Status) if the alarm device is activated.
