2. ASLOC Imaging System ASLOC is an imaging system that is optimised specifically for facial recognition. It is intended for indoor use without the presence of high dust levels. Comprising of a camera and integrated Near Infra-Red (NIR) pulsed illumination, the imaging unit is housed in a dry powder coated aluminium tubular housing supported by a circular dry powder coated aluminium mounting base.
A 12V 2.5A rated power supply unit provides the power for the illumination (please ensure only the specific type of power supply unit provided is used on the ASLOC, replacement units can be ordered though Perception Sensors and Instrumentation). The standby power for the illumination is 0.5 watts with all the LEDs off.

6.6W. The power supply is fully approved for this application and has been EMC compliance tested when in combination with the ASLOC imaging unit. The PSU is 12V DC and can supply the peak current without exceeding the voltages that have been outlined in this document. Connection to power supplies that do not fulfil this criterion will void product warranty.

Please note the touch screen size is 8” diagonal (174mm (H) x 104.4mm (V)), however the overall dimension of the framed screen is 198.8mm (H) x 167.8mm (V) X 34mm (D). The screen sits inside the 61.1mm diameter pole. ASLOC User Manual D-012 Rev 1.0 03/11/2023 Page 7...

The diagram above highlights the advantage of an offset screen. Offsetting the screen prevents the screen framework overhanging either side of the gate application, if the ASLOC pole is positioned at 35° to the subject. The screen must be offset to account for the position of the gate to the subject.
Please note to achieve height the unit would be mounted onto a platform surface. The ASLOC system is provided with a USB2.0, HDMI and 2.1mm DC barrel power extension cable, along with the power supply unit. These cables can be run to a suitable location however please note that the USB2 and HDMI cables have a maximum length of 3 metres.
ASLOC Poles have only one of the two input signals applied (HDMI); therefore, the board will auto select the channel that has signal feed, thus, this Key (S1) does not have function as a Hot Key.

ASLOC the source is HDMI. • There is also an audio option in the 1 layer to adjust volume and mute, however the ASLOC as standard does not provide interfacing audio speakers to the screen. ASLOC User Manual D-012 Rev 1.0 03/11/2023...
It is important to keep the camera lens location free of scratches, obstructions or marks. If using cleaning products on the ASLOC, it is recommended to avoid any containing acetic acid (vinegars).
