INST-164 Revision 4
Description
The Reg-Sentry is a self contained access controller that uses automatic licence plate recognition
(ALPR). It requires a single video input (we recommend only using a Bosch security systems ALPR camera)
and provides a switched relay output (NO/COM/NC) that can be utillised for access control.The switched
output operates in conjunction with a user defineable black/white list that is downloadable to the Reg-Sentry
via an ethernet (TCP/IP) connection .
Installation
The REG-SENTRY will accept an input supply of 12V-24V AC or DC and is supplied with 4m of power
cable already fitted. The input current at 24Vdc is typical 0.15A (3.6W). The recommended rating of a 12Vdc
power supply is 0.34A minimum (4.1W).
The operating temperature range for the unit is -40°C to +50°C.
Camera Installation
Please refer to the installation manual for the ALPR camera unit
Camera Positioning
The camera should be mounted in such a way that in the resulting image of a single line license plate
a horizontal line can be drawn which crosses both the left edge and the right edge of the license plate.
Figure 1 Camera view angles ok
Figure 2 Camera view angles too big
Mount the camera in such way that an ideal image of the license plate is captured when the license
plate is in the centre of in the recorded image. The camera should be focussed on the spot where the
incoming vehicle is likely to stop. It is advantageous to mark this area with a stop sign e.t.c. so that you
can ensure a good image of the vehicles licence plate.
NB The capture software requires that the license plate should take up from 25 to 33% of the image
horizontally. The licence plate should be situated at the specified operating distance of the attached ALPR
camera, please refer to the manufacturer’s installation manual.

INST-164 Revision 4
The maximum vertical view angle of an ALPR camera is 30 degrees.
<30°
The maximum horizontal view angle of an ALPR camera is 25 degrees.
In most systems the horizontal angle and vertical angles are somewhere between 15 and 20 degrees.
Avoid possible blocking objects in the view path of the camera such as (moveable) bars.
Reg-Sentry Installation
Wall Mounting
The REG-SENTRY is supplied in a polycarbonate box, with 4.5mm fixing holes in the base, these can be
accessed by removing the lid of the unit. The mounting holes are located directly below the lid screw mounting
holes. The mounting holes are 113.5mm apart along the width of the base and 163.5mm apart along the
length of the base. See fig 1.

INST-164 Revision 4
Cable Connection
Figure 4: Stand Alone Configuration
There are five cable glands present on the Reg-Sentry (see fig 4). These glands will accommodate
cables with an external diameter of 3mm to 6.5mm.
Video Cable (Screw terminal type Reg-Sentry)
At the top of the box is the video cable entry point. A good quality 75G video cable should be used
between the camera and the Reg-Sentry.
1) Feed the cable into the top of the sentry unit through the cable gland.
2) Strip back the video cable sheath by no more than 10mm (see fig 4).
3) Peel the braid away from the central insulation and twist into a single conductor.
4) Strip back the central Insulation to expose no more than 5mm of conductor (see fig 4).
5) Insert the braid into the screw terminal labelled “GND” that is associated with the “Y” terminal. The
central conductor should be inserted into the screw terminal labelled “Y”. NB Ensure that the camera
is disconnected from its power supply during this operation, and that the video cable screen
(braid) is connected before the central conductor.
6) Lock the cable in position using the screw terminals.
7) Tighten the outer nut of the cable gland until a firm seal has been made to the cable.

INST-164 Revision 4
Video Cable (BNC type Reg-Sentry)
At the top of the box is the video cable entry point. A good quality 75G video cable should be used
between the camera and the Reg-Sentry.
1) Feed the cable into the top of the sentry unit through the cable gland.
2) Refer to BNC connector manufacturers instructions on how to attach the BNC to the internal end of
the video cable.
3) Connect the BNC connector to the socket provided. NB Ensure that the camera is disconnected
from its power supply during this operation.
4) Tighten the outer nut of the cable gland until a firm seal has been made to the cable.
Relay Cable
A 3 core cable will be required to access the relay outputs (for installation to the barrier), normally closed
(NC), Common (COM) and normally open (NO).
1) Feed the cable into the cable gland at the bottom of the Reg-Sentry (see fig 4).
2) Strip the cable sheath to expose no more than 20mm of the 3 internal cables.
3) Strip the internal cables to expose no more than 5mm of conductor.
4) Insert the cables into the NC/COM/NO screw terminals and lock down.
5) Tighten the outer nut of the cable gland until a firm seal has been made to the cable.
The relay outputs will need to be connected to the control mechanism of the barrier / Gate to be controlled.
You will need to refer to the manufacturer’s installation manual. The relay is rated at 30W with a maximum
operating voltage of 125 VAC and 110VDC.
Power Cable
A 4mm power cable is already provided. This will accept both AC and DC inputs from 12 to 24 volts. The input
current at 24Vdc is typical 0.15A (3.6W). The recommended rating of a 12Vdc power supply is 0.34A minimum
(4.1W).
Network Connection
A network connection is required to commission the Reg-Sentry. This can either be from a standalone
PC/Laptop (i.e. an adhoc connection) or a networked system. A standard network cable (Cat 5e) will be
adequate for either situation.
A cable gland has been provided should you wish to hardwire the unit to your network, however you will
need to crimp an RJ45 connector internally to the Reg-Sentry to do this as the RJ45 connector will not pass
through the cable gland.
Page 6 of 18
INST-164 Revision 4
Commissioning
To commission the Reg-Sentry you will need to connect the unit to a PC using the network connector on
the p.c.b. Use a standard network cable (Cat 5e) to make this connection.
The following instructions assume a good working knowledge of the windows operating system.
If you are networking this unit, it is assumed that you have a good working knowledge of network
systems. If either of these assumptions are incorrect, it advised that you consult an expert before
attempting to commission the Reg-Sentry unit.
The Reg-Sentry uses a TCP/IP interface which is DHCP enabled. If a DHCP server is not detected the
Reg-Sentry unit will default to a static IP address of 192.168.0.204.
The Reg-Sentry uses port 50000 for its communications, if you are using a firewall you will need to
configure the firewall to allow access to port 50000 and to the SentryViewer program.
1) Install the Sentry Viewer onto your PC/Laptop using the installer package provided on the RegSentry CD.
Alternatively you can copy the “Reg-Sentry Viewer” folder onto your computer ( i.e. C:\ ). The “RegSentry Viewer” folder can be found on the Reg-Sentry CD.
2) Attach the Reg-Sentry to the computer using a Cat5e network cable.
3) Apply power to the Reg-Sentry. The “DSP_F” LED will start flashing, wait until this LED stops
flashing and is continually lit (the LED is green in colour). N.B. no processing will occur until this
LED has stopped flashing.
4) Launch the Sentry Viewer using the executable file “SentryViewer.exe” or desktop icon.
Figure 5: Sentry ID Text Box
5) Enter the IP address assigned to the Reg-Sentry into Sentry ID box. The default IP address when not
using a DHCP server is 192.168.0.204. If you are connecting to a DHCP server then you will need to
contact your network administrator to obtain the IP address of your device. If you have problems
connecting to the Reg-Sentry then refer to the Network settings section of this manual.

6) Once connected, the password box will now appear in front of the viewer. Initially, the password is
unset. Clicking on the ok button without entering any text into the box will give you full access to the
sentry viewer.
Figure 6: Password Box
7) The Sentry Viewer has a live video stream facility. This live video stream will however slow down the
function of the Reg-Sentry significantly and is only provided as an aid to commissioning the unit
i.e. for setting up your camera placement to achieve an optimum viewing angle.
The live video stream is activated by clicking on the “Start” button. The blue LED labelled “DSP
2” indicates when the live video stream is active.
The “Stop” button will deactivate the live video stream.
The “Capture” button enables a single frame from the camera to be captured, this can then be
stored by clicking on the “Save” button. The resulting JPEG file is stored in a file location that can be
set in the settings menu.

8.1) The name of the sentry unit can be set by entering an appropriate name into the camera
name text box
8.2) The onboard date can be set using the dropdown calendar.
8.3) The onboard time can be set using the “time” text box and the up/down arrows
8.4) Security level, this can be set for high, medium and low. The high setting only allows for exact
matches to the black/white list. The medium setting will allow for a 1 character difference and the low
setting will allow a 2 character difference from the black/white list.
8.5) A variable time period for the relay switch can be set using the “Close Relay Duration” text
box.
8.6) Black/White List Type, a white list will close the relay switch for any number plate on the
black/white list. A black list will close the relay switch for any number plate not on the black/white list.
The Reg-Sentry can only be operated as either a black list or a white list.
8.7) While the Sentry Viewer has an active connection with a Reg-Sentry unit it will copy the
transaction list (text only) into a text file. The location of this text file can be specified using the
“storage directory” text box. NB Any captured camera frames that are saved will also be saved in this
directory.
8.8) While the SentryViewer has an active connection with a Reg-Sentry unit, it can store
recognition images to a local hard drive. To activate this function, click on the tickbox, “save
recognition images”. All images will be saved in the image storage path. The location can be
specified using the “image storage path” text box.

Trouble Shooting
Network Setting
The default Reg-Sentry IP address is 192.168.0.204. It is possible that this IP address will be
incompatible with your hardware i.e. it is not within the range of IP addresses that your server or computer will
allow. If a non DHCP server is used or the device is connected directly to a PC / Laptop this incompatibility
can cause the Reg-Sentry not to communicate with the computer running the Sentry Viewer software.
If this is the case then you will need to alter the network setting of your “Local Area Connection” on
your PC or laptop to enable initial access to the Reg-Sentry. This can be done by selecting “My Network
places” from the windows start menu and viewing the network connections page.
