Louroe Electronics DIGIFACT A User manual

The Digifact™ A is a networked audio monitoring and streaming device which streams audio over
several industry standard RTP protocols. The wide dynamic range microphone supports a wide
frequency response capable of picking up low and high frequency sounds. The device features a
robust quad-core microprocessor that has the capability of integrating signal processing
applications, audio enhancements and analytic applications. Analytic applications can be added to
the device to detect and report events such as:
- Aggression/Duress
- Gunshots/Explosions
- Breaking Glass
- Car/Panic Alarms

NETWORK AND POWER CONNECTION
INSTALLATION TIP: For instances where the CAT5/6 cable is to make a side entry to the rear of the unit, it is
recommended that the cable not be terminated using a molded strain relief, and instead the cable wound once
around the inner ring of the device to provide strain relief to the cable.
MOUNTING
The Digifact Model A is cylindrical, 4.7” dia. x 2” H, and has four mounting holes for surface mounting to a
ceiling or other flat surface. It should be positioned so that the microphone is 4’ to 8’ from the area of desired
coverage.

ALARM OUTPUT CONNECTIONS
AFemale Rj45 jack is located on the rear of the unit for 10BASE-T/100BASE-TX PoE connection using
CAT5/6 cable. If no PoE connection is available (network only) an optional two-pin header is available for
connection of a 5V DC 2A external power supply (not included), as depicted in the image below. Once
the device is powered on (PoE or ext power) the blue light on the front of the device should turn on.
Four digital alarm output ports are available for connection to external devices, the alarm
outputs can be set to trigger from analytic and volume threshold events. If used with an
inductive load, e.g. a relay, a diode must be connected in parallel with the load, for protection
against voltage transients.

WIRE TERMINATIONS:
Alarm output and external power supply ports use a 5 and 2
position respectively 0.1” (2.54mm) pitch vertical header, the
mating connector needs to be terminated by the installer,
recommended mating connectors are:
5-pin: TE Conn 3-640441-5
2-pin: TE Conn 3-640441-2

DEVICE DISCOVERY
The Digifact A is by default set to obtain an IP address from the network it is connected to (DHCP), hence it
must be connected to a suitable DHCP server. To discover the device on a network, the following commands
need to be run through windows powershell to locate the device name;
dns-sd -B _simic._tcp

Once the device name has been located, the following script must be run:
to locate the device IP address:
dns-sd -G v4 .local<devicename>
The device IP address can them be typed into an internet browser (Chrome, Internet Explorer, Firefox etc.) to
access the device user interface page.
DEFAULT PASSWORD CHANGE
On first use the default password for the device is;
username: admin
password: admin
After entering the above information, the device will request the user to change the default password
Once the default password has been changed the device prompts to re-enter the new password to login
to the device.

The live view screen of the device contains information and controls such as;
Device firmware version, device name, acoustic monitoring settings, sound detector settings, audio activity
spectrogram, listen live control, ability to add analytic licenses as well as access to the other device parameter
pages.
