LPR Cameras Setup & Playbook For more information on LPR Installation and Setup, click here. LPR Camera Information What is LPR? Connecting to the PL8RDR In order to scan plates, the PL8RDR computer will need to be connected to a handheld device running the OPSCOM enforcement app. The PL8RDR will broadcast a Wi-Fi network, pl8rdr.opscom . Connect to this network on your device. The network password is T0maha3k . To check your PL8RDR signal strength, refer to this wiki article .  PL8RDR Signal Strength Signal Strength The PL8RDR is a proxy/bridge to the internet through WIFI or your cellular provider (LTE).  When connected, can you open a browser window to see if you are able to browse the internet. If not, you should check your signal strength.  If you are a WIFI user you can test signal strength with multiple applications that are typical a free download.  If you are a LTE user you can see the signal strength by looking at the device's status from the LPR Scanning screen. By tapping on Status at the top right of the screen you will be presented with a list of items and their connection status.  Signal Strength will appear at the bottom of this list. The closer to zero the better. dBm Comment -51 Best -80 Minimum for best connectivity -90 Noisy connection; not stable -96 our office window (usable) -107 LTE tablet outside (usable) Phone in basement -111 Worst failed failure to get signal Tattile LPR Camera Powering a Tattile Mobile LPR Camera Standard Hardware There are several pieces of gear that comprise the OPSCOM LPR system. A typical system includes the following items: 2-Tattile Mobile LPR Cameras with one connector cable per camera 1-PL8RDR Device 4G/LTE  1-4G/LTE Tablet 1-3” Bluetooth printer 1-RAM Universal No-Drill Tablet Vehicle Mount & Accessories Each Mobile LPR camera will need a cable built to accommodate communication between the PL8RDR device and the camera. Cables are best to be custom built in order to suit the logistics of what vehicle is being used and where the camera is located on the vehicle. Note:   It is best practice to have the proper amount of cable so no coiling or stretching of the cable is required.  Standard Power Cable Used to supply power to the camera. The camera will connect to the PL8RDR computer wirelessly. Parts Required for Each Cable BINDER M16 99-5672-19-08 series 423 connector (part code T18654) Power cable - RED/BLACK cable 0.50 mm cut to the proper length to accommodate the distance from the cable to the power source  an inline fuse is suggested This is the front view; holding the connector by the wires and viewing the terminals. Advanced Cable For Troubleshooting The following diagram represents how the cable should be wired in an advanced setup where the camera communicates with the PL8RDR through a standard ethernet cable.  This is more likely to be used in troubleshooting rather than typical operation.

Configure Tattile LPR Camera For the Survision LPR Camera configuration, go to Survision LPR Camera Configuration Connecting Wirelessly The first step is to connect to your  PL8RDR  device via wireless connection. To do so bring up your systems  Network Settings by following the steps below Click on the  Windows Home Button  and start typing  Control Panel . It should pop up under Best  Match as you are typing. Click on  Control Panel  to access your  Computer's Settings . A list of all available configuration items will appear. Click on Network and Internet. In  Network and Sharing Center  settings click on  Connect to a Network . Connect to pl8rdr.opscom First make sure  Wi-Fi  is turned on by clicking the network icon at the bottom right of your screen. You will see a list of networks available to you. In this case we are looking for the  pl8rdr.opscom  network. Clicking the  pl8rdr.opsom  network will open a screen where you can click on  Connect  to join the network. You can also utilize the  Connect automatically check box do avoid having to connect manually each time. Since the network is secured a password/PIN is required to connect. Click on  Connect using a secure key instead to bring up a seperate password entry field. Enter the password into the empty field and click on  Next . Note: The password is provided by OPSCOM. If you do not know your password please contact support@ops-com.com You will be prompted to allow your PC to be discoverable by other PCs on this network. Click  No  as you do not want this connection to be open to other PC's. You will see the connection status below the  pl8rdr.opscom  network appear as  Connected .  Connect to the Camera Now you can open a browser and enter the IP address of your camera in the go to field. You will also need to follow the IP address with a port number. For mobile cameras the port number is 1080 therefore the URL would look like this: http://[IPAddress][colon][port number] as in the example below you can see the URL as http://10.42.0.140:1080 If you do not know the IP address of your camera see  How to Find the IP Address of your Camera found below. You will be prompted for a  Username  and  Password .  Username Password superuser superuser The main  Number Plate Reader Configurations page will appear. Note the IP address and port number in the browser as well as the rest of the URL that will resolve automatically. Naming Mobile Cameras Under System → Network you can name the camera(s) appropriately. Mobile-L = Drivers side Mobile-R = Passenger side How to Find the IP Address of your Camera On the handheld unit go to main menu and tap on  LPR Scanning . Once in the LPR screen tap on  Status  near the top right of the screen. You will see a list of connected devices. The device  Type  should be  Tattile camera wifi.  Please note that due to new cameras coming onto the market, your PL8RDR may list a camera as an unknown device. In this case the cameras IP address was  10.42.0.140 . Enter the IP address for your device with port  :1080  into the browsers URL and hit  Enter . The below screen shot is taken after the cameras have read some plates.  Notice the "stats" entry which clearly lists the camera IP addresses. Also note that sometimes the system is not able to determine which device is a camera. Connect to a Tattile Mobile Camera First Time Connection Power up the camera and give it a few minutes to fully boot up. At that point you will see the camera in your network connections list. Note the network name reflects the serial number of the camera In this case ANPR-2010011339 Click connect to establish a connection between your computer and the camera's hotspot. The standard IP address for the camera coming from the factory is set at 192.168.150.1 You will also have to put the port number in your URL when trying to connect through your browser. Open a browser and enter the camera IP and port into the address bar. In this case it will be 192.168.150.1:1080 (Where 192.168.150.1 is the camera IP and 1080 is the port number) You will be prompted to enter a user name and password.  Username superuser Password superuser You will then be directed to the Plate Reader Tab of the camera configuration. There are Specific areas that you will need to configure. On the Plate Reader tab you will edit: General Settings Event Actions Also known as TCP Events JPEG Image Header Configuration Plate Reader Settings On the System tab you will edit: Network Settings  It is very important to edit the network settings properly and in a proper sequence. If for example you configure the camera to connect to the PL8RDR but forget to set it to assign an IP (DHCP) and save the changes. You will not be able to log in to the camera wirelessly.

One would be to simply update the existing firmware. The other is changing the firmware based on your specific region. There is specific firmware tailored to the region in which you are using the camera. There would be firmware specific to the state of California and it's surrounding states that would be optimized for reading plates in those states as opposed to plates in Florida for example, Firmware updates allow you to update the entire system. This instruction applies to ANPR Mobile cameras.  How to Update Two updating methods are available: Upgrade firmware keeping current settings:  in this section, the update is carried out without changing the previously configured parameters. Press the Browse button and select the update file from the PC file list. Once this file has been selected, press the Upload button and confirm the operation. When update completes, the User is asked to reboot the ANPR Mobile machine by pressing the Reset button displayed on screen.  Upgrade firmware with default settings:  in this section, the upgrade is carried out by deleting all user-defined parameters and reloading the default settings of the new .BIN file just loaded using the Browse and Upload command sequence. This procedure is the same as the one previously described. How do I find my current firmware version? Go to the  System  tab of the camera configuration screens. Look for  Device Info. Click on  Device Info  to bring up the Device Info screen. The firmware version is the first line in the information list. If it is established that the firmware is out of date, go back to the system tab and look for the  Firmware  menu item. Click on  Firmware  to bring yo to the update page. If you are in the process of upgrading the firmware there are two main factors to consider. You are either starting with a new camera in which case you will upgrade with default settings or, if you have a previously configured camera you will be upgrading the firmware keeping current settings. Navigate to the location of the firmware update file to select it for upload. This will be a .gpg file. The file will be staged for upload. Notice the file name appears in the upgrade interface. Click on Upload to complete the upgrade process. This may take a little time.  Trobleshooting Tips Powering the Camera If the camera is not connecting to the PL8RDR there may be issues with power. Ensure that the connections are sturdy and follow the guide to Powering the Camera. One way to check a camera to ensure it is powered on is to power up the unit and view the front of the camera using a cell phone camera. The use of the camera viewfinder does two things. It shields you from looking directly into the infrared light as well as allow you to see a slight flicker in the 6 lights on the front of the camera. Checking Firmware updates. You should always ensure you have the latest firmware installed.  Adjusting the Camera's View Depending on the application of your camera, whether it be fixed or mobile, there are adjustments that can be made to improve accuracy and speed of reads. Adjusting the angle, height and width of camera's read area can improve performance by simply defining the camera's sweet spot so to speak.    Survision LPR Camera Setting Up Your Survision LPR Camera Note: This is assuming you have a PL8RDR computer already set up. See the PL8RDR information section below for more details. Powering the Camera Your Survision camera should come with a cable. This is only used for providing power to the camera; the camera connects to the PL8RDR wirelessly. Power on both the PL8RDR and the Survision camera. Connecting to a Handheld Device You will find the information for connecting to the PL8RDR here . Positioning the Camera Choose a plate on a vehicle to be your reference. Park your enforcement vehicle behind it and to the side, as if you were driving past a street-parked car. The camera on your vehicle should be  5 meters  away from the reference plate, and angled  less than 30 degrees  off the front of the plate. (This diagram shows a vertical angle, but the same applies horizontally.) Connect to the pl8rdr.opscom Wi-Fi network on a device of your choice. The screenshots in this demonstration are from a phone, but any laptop or mobile device will work. On your tablet (or other connected device) open a web browser, enter the IP address of the camera. For OPSCOM's test cameras, use the IPs below: One camera: 10.42.0.11 Two cameras: 10.42.0.11 and 10.42.0.12 Click on "Configuration assistant". Proceed through the first 3 screens by clicking "Next" each time. These settings will have already been configured for you. On the 4th screen, you will be prompted to set the camera angle. Adjust the camera on your vehicle until the plate you have chosen as your reference point is centered in the green box. The lines of text above the camera feed should all turn green when it is set correctly. When you are done, click "Next". On the 5th screen, leave all the fields blank and click "Finish". The next screen may display an error message saying no address is configured. You can safely ignore this; the address is configured on the PL8RDR. Your camera should now be set up at the correct angle. You can go through this quick setup process every time you need to reposition the camera on your vehicle. LPR Annual Camera Maintenance Suggestions 1. Physical & Lens Care Since the Picopak relies on high-speed image capture (60 fps) and internal OCR (Optical Character Recognition), image clarity is your top priority. Lens Cleanliness:  Dust, mud, or road salt can degrade reading accuracy by 20–30%. Clean the lens weekly (or daily in harsh weather) using a  microfiber cloth  and a lens-safe solution. Never spray the solution directly onto the camera; apply it to the cloth first. Check for Obstructions:  Ensure the camera's field of view is clear. For mobile setups, check that vehicle parts (like a hood or mirror) or mounting brackets haven't shifted into the frame. Housing Integrity:  Periodically inspect the aluminum casing for cracks or signs of impact. While it is  IP67-rated  (waterproof and dustproof), a significant hit can compromise the seals. 2. Connection & Power Maintenance The Picopak is low-energy (approx. 6W) and typically powered via 12/24 VDC. Cable Inspection:  Mobile environments involve vibration and movement. Regularly check the  Amphenol connectors  and cables for fraying, oxidation, or loose connections. Waterproofing Seals:  Ensure the RJ45 protective cover is securely tightened (recommended torque is  0.8 to 1.5 N·m ) to prevent water ingress into the network port. Battery Health:  If using a portable battery kit, verify the charge levels and connector integrity to prevent sudden system shutdowns, which can occasionally corrupt data logs. 3. Software & Firmware Management Survision cameras are "smart" devices with AI-powered firmware that requires periodic updates to recognize new license plate designs or syntaxes. Firmware Updates:  Survision typically releases updates  2–3 times a year . These are critical for maintaining high accuracy as vehicle plate styles change. Remote Monitoring (Survision Guard):  It is highly recommended to use the  Survision Guard  service. This tool remotely monitors the camera’s "health," including internal temperature, power failures, and "Confidence Levels" (how sure the camera is of its own readings). Accuracy Audits:  Perform a quarterly test by comparing the camera’s output against a manual log of 10–20 plates to ensure the "Confidence Ratio" hasn't drifted due to focus or vibration issues. 4. Technical Specifications Summary Feature Requirement / Limit Operating Temp -40°C to +55°C (-40°F to +131°F) Protection Rating IP67 (Dust tight / Immersion up to 1m) Power Supply 12/24 VDC (+/- 3V) MTBF 56,000 hours minimum (approx. 6.4 years) Static Camera Setup Adding a Camera In order to activate your LPR access, and if equipped, information feed for Make, Model Color (MMC) information, you must access your system configuration and change two settings, as follows; Go to System Configuration and click on System Settings . Select the License Plate Recognition tab. There will be two checkboxes to enable, one is called  Using Mobile LPR.  The other is called  Enable MMC. The setting that is labeled as MMC is only going to work if you have a camera that supports MAKE, MODEL, COLOR information collection. If so, enable the checkbox for this setting as well. Other wise, this information will be discarded even if your camera does collect it. To begin go to the Violations menu and click on LPR and Chalking. Then click on Camera Setup. The LPR Camera Configuration Page displays. Fill in the form with the required information: Camera Name Camera Type (entrance, exit or tracking) Camera IP You may also want to record the following optional information: Admin link (to access camera configuration Username Password Notes Click save to complete the process. Once the camera is configured you are able to look up or edit the information from this interface as well. Clicking on this link will bring you to the actual camera where you log in using the displayed credentials in order to configure or adjust settings on the camera itself. When complete LPR Events can be set to display data from the specific camera selected. LPR Plate Lookups and Fuzzy Filtering Background The OperationsCommander system has the ability for the system to map plates to new values. In layman's terms this means that this process of filtration can take an image of a plate and find many possibilities of what the plate may be matched to based on commonly misconstrued characters and  the license plates registered or in the known area database. An example of this may be a plate that is read by LPR may be read as ABC128 when the plate is actually ABC123  . The user is able to make this update and store the details.  This can be problematic for the user if the plate is never seen again and 8  's are regularly interpreted as 3  's Update This issue in the functionality of the LPR software is addressed by the use of the above methods and the use of the lookup table implemented to match which characters are easily misconstrued. The sample lookup table that follows is comprised of data from past LPR updates by users; Character Similar Characters Character Similar Characters 1 "1I" K "HKR" 2 "2Z" M "HKM" 3 "38B" O "0DOQ" 5 "5S" P "FP" 8 "38B" Q "0DOQ" B "38B" R "HKR" D "0DOQ" T "TY" E "EF" V "VY" F "EFP" Y "VTY" H "HKMR" Z "2Z" I "1I" Special Characters The # (pound or hash) sign is a special wildcard character.  If this is seen, the PL8RDR has seen a character but is not sure what it is. Handheld Example Navigate to the 'Search Vehicles' menu on the main menu screen. This will bring you to this search bar and type in the license plate number that you are looking for. For this example we are using the license plate number  AFVK663 . Since we have looked up  AFVK663  the Handheld will match you with the registered vehicle  APVK668 . It does this because in coherence with the lookup table the character  3  is similar to the number  8  and  F  is similar to the character  V  therefore fixing the license plate error by finding a plate in the database that matches.  | Application on Admin Side The aforementioned example is not the only field in which the fuzzy filtration system is applied. It is also shown in any form of  license plate search that is on the admin side as well as the license plate reader's capture log. For the extent of this example we will be looking for license plate  ABC128 in the License Plate Recognition (LPR) Capture Log although this method will work for any license plate search. Administration Example Navigate to the License Plate Recognition (LPR) Capture Log by clicking view LPR events under the License Plate Recognition sub-header in the Parking Management tab. This will bring you to the License Plate Recognition (LPR) Capture Log which is where you can search for your chosen license plate. In this scenario we will search our license plate  ABC128  with the 'Fuzzy Search' prompt toggled off. Expected Result: No License Plates Found. Now if we repeat this search with the 'Fuzzy Search' toggled on the results are vastly different with there being many License Plate Captures for the registered vehicle with license plate  ABC123  which is what we want. It does this by referencing the previously provided lookup table and repeating license plate searches for each variation of the license plate's similar characters and by doing so it corrects any errors in the LPR reads.  Vehicle Counts Audit Report To view the  Audit Report  gpo to the  Parking Management Menu  Item, hover over  License Plate Recognition  and select  View LPR Report  from the drop down menu. The  License Plate Recognition (LPR) Audit Log  will appear. From this interface you can: Set the timeframe you wish to report on Select the Camera or Cameras (Hold the control key down to select multiples) you wish to report on Select the event type (Entrance, Exit, Tracking) View the results.  Vehicle counts can also be manually reset, To do so go to admin options and hover over Parking then select Manage Lot Groups.

This information acts like a 24 x 7 Patrol Officer and serves as proof during disputes or appeals, as the time-stamped image is acceptable in a court of law if the date/time stamp is clear. If your camera hardware supports it, a static camera chalk includes the chalk image associated with the vehicle entry, which shows both the license plate and the entire car with a visible date/time stamp. This creates a digital trail that replaces manual tire marking. When reviewing past chalks, you can see a map location of where the vehicle was chalked, a date and time stamp for the chalk event, and an image taken at the time (accessible via a camera icon). There may also be comments added by the officer at the time of chalking, and a distance reading indicating the distance from the first chalk record to the present position. Best Practices and Considerations Audit Camera Accuracy: Regularly check that the camera is pointed correctly and that the images are clearly showing the vehicle in frame. Dispute Resolution: When handling an appeal, always provide the Chalk Image as it shows both the plate and the vehicle context, which is typically acceptable in a court of law.
