X-Vision Professional NPR Camera Guida all'installazione
XVision Professional NPR Camera
Set up and configuration of XVision Professional NPR cameras
With regular CCTV cameras it is usually not possible to read a
number plate of a vehicle as the high light from the vehicles
headlights cause the number plate to appear washed out.
With the Xvision Professional NPR camera it is possible to
suppress high light situations in order to accurately read a number
plate of a vehicle.
Most cameras in the industry require very little set up as they are plug and play, by this we mean that you can simply
plug a power and a video cable into the camera, connect it to your DVR/monitor and you will get an image. While this
will suffice for 80% of the public, with the NPR range there will be a little set up required. Please follow the following
steps to achieve the most out of this camera:
To get the best results it is advised to mount the camera in the environment that it is going to be placed; all configuration
can be done when the camera is installed.
You will require for this:
1. Xvision Professional NPR camera
2. Power supply
3. PNP, RG59 or CAT 5 cable
4. Monitor/Test monitor
5. Another person to assist with testing
1. Check you have everything required for this installation. Test the camera locally before mounting or running any
cables to ensure that it is working correctly. If it at this time you find any missing items or require any assistance
please contact our technical team on 0871 222 1430.
2. Now that you’ve completed step one, find the cameras mounting position. Ideally this needs to be mounted above the
main beam of the vehicle headlights; 6-8 feet from the ground is a good suggested height. Once you have found this
location proceed to run all the cables and mount the camera. You can make any adjustments to the cameras angle
by using these two parts:
3. Once the cameras mounted get your assistant to do a few practice runs; this will help you find the best angle to
capture the number plate. Once you’ve found your ideal location get the vehicle to stop there.
4. For this step you might require a test monitor, the enclosed test lead
(pictured to the right), or another person to view the monitor while
you adjust the camera. If you are going to use a test monitor with the
test lead please insert here:
Proceed by focussing the camera on your desired area. To do this you just need to loosen and then rotate the two
dials on the lens cover; the first dial (labelled ∞- N) adjusts the focus and the second dial (labelled W –T) adjusts the
zoom. Proceed by moving the second dial all the way up; this will give you a narrow angle. Now tighten the dial. Adjust
the first dial until the picture is in focus and then tighten it to secure.
Note: To get access to the test monitor connection you will need to take the lens cover off by removing these screws.
Once removed you will see the test monitor connection shown on the previous page.
5. This should give you an ideal daytime image of the number plate. Make sure you are happy with your viewing angle
and make any last minute adjustments following above steps in point 2.
6. Next you will need to get access to the on screen menu
of the camera. To do this you will need to remove the
cap on the underside of the camera body.
7. The following steps will need to be done when it is dark so
that you can get the best picture. Again, using your test
monitor or your assistant, press the menu button on the
camera which will bring up the on-screen display menu
(as pictured on the right). Please see pages 9-11 of
the cameras manual for a detailed description of these
functions.
Move down to option 4 (Backlight) and set it to HLC.
Press the joystick button in to confirm this.
Navigate down to option 2 (Exposure) and press the menu button
again to enter. In here you will find shutter, AGC and sense-up as
shown here.
In total four settings will need to be adjusted; please be aware that these settings are just a guide and will differ
depending on your environment:
Shutter speed; ensure that this is set to A.FLK.
AGC should be set to High.
BLC should be set to HLC. Click the menu in to enter its further settings.
Day/Night should be set to Indoor or External, depending on the environment.
Once you are done go down to Return, push the menu button and then go to Exit.
You should now have a perfect image for recording number plates at night. You may find the day time image to suffer
as a result; you can always readjust the shutter speed to accommodate the day time environment but make note to
change this back at dusk. If possible it is advised to set up a second camera configured for a better day time image; this
does not necessarily have to be an NPR camera. Please contact the sales team if this is required.
