SIM Cards for ANPR Cameras: A Guide for Installers and Operators
Automatic Number Plate Recognition (ANPR) is one of the most widely deployed vehicle surveillance technologies in the UK. Car parks, construction sites, access control points, local authority enforcement zones, and road junctions across the country depend on ANPR to capture, process, and act on vehicle registration data. The majority of these systems rely on 4G cellular connectivity to transmit plate read data to a cloud management platform and to allow engineers to access cameras and routers remotely.
Choosing the right SIM card for an ANPR deployment is a technical decision that affects security, reliability, and the ongoing cost of the installation. This guide explains how ANPR systems connect to the internet, what SIM configuration the industry now uses as standard, how much data to budget for, and why Millbeck Communications has been the IoT SIM and hardware supplier of choice for UK ANPR installers for over ten years.
How ANPR Systems Connect: Two Common Architectures
Not all 4G-connected ANPR systems use the same architecture. There are two distinct approaches. The SIM card goes in a different place depending on which one applies to your installation.
Camera with built-in 4G modem
Some ANPR cameras include an integrated 4G modem. The SIM sits inside the camera housing itself. This is most common in solar-powered standalone units and redeployable systems, where a single device must handle power, processing, connectivity, and plate capture with no supporting equipment. Examples include the Suilvision Lightning 5X, Milesight solar ANPR cameras, certain WCCTV redeployable tower units, and some Hikvision and Dahua portable models. In these installations, the SIM is inserted directly into the camera and the APN is configured through the camera’s own interface or management software.
IP ANPR camera connected via a separate 4G router
This is the more common architecture for fixed-site installations. A standard IP ANPR camera connects via PoE (Power over Ethernet) to a 4G router installed in a roadside cabinet or pole enclosure. The router provides the WAN connection. The camera connects to the router over the local network exactly as it would connect to a broadband router. The SIM and APN are configured on the router, not the camera.
This two-device approach is the architecture used in most car park, access control, and fixed enforcement installations. Teltonika industrial routers are widely specified for this role because of their compact DIN-rail form factor, dual SIM failover, VPN capability, and support for Teltonika RMS remote management. Proroute routers are also well established among UK ANPR installers – their compact build and industrial reliability have made them a common choice for outdoor cabinet environments. Customers using Milesight cameras frequently pair them with Milesight routers to benefit from the same manufacturer’s management ecosystem.
Which architecture do you have?
If your camera has a SIM card slot built in, the SIM goes in the camera. If your camera connects via a network cable to a separate device in a cabinet, the SIM goes in that device. Call Millbeck on 0300 124 6181 if you are unsure – the team can advise on the correct configuration for your specific camera and router combination.
ANPR Camera Manufacturers Active in the UK Market
The following manufacturers supply ANPR cameras used in UK deployments. The connectivity approach varies. Some cameras include embedded 4G. Others connect via PoE to a separate router.
Suilvision
Suilvision is a UK ANPR manufacturer based in Preston, Lancashire. Their cameras are installed in over 4,500 car parks across the UK, making them one of the most widely deployed ANPR camera brands in the country. The Suilvision range includes the Nimrod, Phantom, Bollard, and Lightning 5X models. The Lightning 5X integrates an i7 processor, 4G and Wi-Fi modem, and motorised lens into a single housing – it requires only a power feed and operates as a self-contained unit. The Nimrod, Phantom, and Bollard cameras connect via PoE and are used in the standard two-device architecture with a separate router. All Suilvision cameras work with MySuilvision management software and integrate with Unity5’s Zatpark enforcement platform.
Milesight
Milesight produces solar-powered 4G ANPR cameras used in car park management and traffic monitoring across the UK. Their cameras use on-device edge AI processing for plate recognition, with 4G transmitting read data and alerts to cloud platforms. Milesight cameras are used with Unity5’s Zatpark platform and have been deployed in multi-site car park management projects. Customers using Milesight cameras often opt for Milesight routers to benefit from the same manufacturer’s management ecosystem, though the cameras are compatible with any standard 4G router.
MAV Systems
MAV Systems is a UK ANPR manufacturer supplying cameras to policing, traffic enforcement, tolling, and parking sectors. Part of The Traffic Group, their Rapier, Sabre, and IQX camera ranges are used in fixed and mobile deployments across the UK and internationally. MAV cameras connect to back-office platforms via standard network connections. Zatpark integrates with MAV cameras via the UTMC standard.
QRO Solutions
QRO Solutions builds the Harrier AI and Harrier Mini fixed ANPR cameras with built-in GPS and 4G connectivity, as well as in-vehicle ANPR systems for law enforcement. Their QBOX processing unit manages the ANPR engine and 4G data transmission to force management servers and back-office platforms.
Hikvision
Hikvision’s ANPR range covers both fixed and redeployable use cases. The DS-2XS6A46G1 solar ANPR kit uses a built-in 4G module for off-grid deployments. The iDS-MCD202 portable speed dome integrates 4G, GPS, and Wi-Fi for mobile enforcement. Fixed installation cameras (the iDS-2CD7 series and similar) connect via PoE and use a separate router for WAN access. These are among the most widely deployed fixed ANPR cameras in UK car parks and access control installations.
Dahua
Dahua’s WizMind ANPR range includes mobile units with integrated 4G and fixed PoE cameras for installation with a separate router. Dahua cameras integrate with DSS Pro and third-party parking and enforcement management platforms.
WCCTV
WCCTV manufactures redeployable CCTV and ANPR towers that connect via 4G and 5G to their Stellifii cloud platform. WCCTV systems operate autonomously on solar or battery power. The 4G modem and connectivity are built into the tower unit itself. WCCTV is one of the most widely used providers of mobile ANPR for local authorities, police, and construction site security in the UK.
Leonardo
Leonardo provides ANPR systems to UK law enforcement and government agencies, including fixed, mobile, and portable camera deployments feeding the National ANPR Service (NAS). Their systems use secure cellular connectivity for field-to-back-office data transmission.
Cloud Management Platforms for ANPR
Modern ANPR installations connect to a cloud-based management platform. The platform receives plate read data, cross-references registrations against permit or hotlist databases, and initiates enforcement actions or access control responses. 4G cellular is the connection that links each camera or router to this platform. The SIM provides the outbound data path from the installation point to the cloud.
Unity5 Zatpark
Unity5 is one of the most widely used parking enforcement software providers in the UK. Their Zatpark platform is used by 1 in 3 UK local authorities and by over 130 private parking operators. Zatpark is camera-agnostic, integrating with any UTMC-standard ANPR camera. Confirmed integrations include MAV, Suilvision, Vaxtor, Reolink, and ARVOO. Zatpark handles enforcement, permit management, DVLA KADOE lookups, payment integrations, and appeals management from a single cloud dashboard. Millbeck’s private APN SIM configuration is fully compatible with Zatpark’s outbound connection model.
MySuilvision
Suilvision’s own cloud management platform, used with their camera range. Provides remote access to plate read data, hotlist management, and reporting for car park operators and enforcement teams.
WCCTV Stellifii
WCCTV’s proprietary platform, used with their redeployable CCTV and ANPR tower products. Provides live video access, plate read data, PTZ camera control, and system health monitoring from a web browser or mobile device.
Genetec AutoVu
Genetec AutoVu is used in larger-scale and law enforcement ANPR deployments. It forms part of Genetec’s Security Center platform and integrates ANPR data with video surveillance and access control records.
What Type of SIM Card Do ANPR Systems Need?
ANPR systems handle vehicle registration data, which is personal data under UK GDPR. The connectivity architecture must reflect this. In almost all current UK ANPR deployments, the camera or router connects outbound to a cloud management platform. The SIM does not need to accept inbound connections from the open internet. This is the key reason the industry has moved firmly to private IP SIM cards on private APNs.
Multi-network roaming SIM with private IP – the standard choice
The correct SIM type for the vast majority of UK ANPR installations is a multi-network roaming SIM configured with a private IP address on a dedicated private APN. This does two things at once. The multi-network roaming capability means the SIM automatically connects to the strongest available network at the installation point – EE, Vodafone, O2, or Three – rather than being locked to one provider. This is critical for redeployable systems and important for fixed installations in locations where a single network may have gaps in coverage.
The private APN routes all traffic – plate read uploads and remote management access – through a closed private network. Each camera or router receives a private IP address. Traffic never traverses the public internet. Engineers can securely access the router or camera for remote configuration, diagnostics, and firmware updates over the same SIM connection that carries the plate read data. This architecture satisfies GDPR requirements for data in transit and meets the security standards expected by professional ANPR platforms including Zatpark, MySuilvision, and Genetec AutoVu.
A note on public IP SIM cards
Older ANPR installations sometimes used public IP SIM cards, where the camera or router was assigned a publicly routable IP address. This approach has been phased out across the industry for security reasons. A device with a public IP is directly reachable from the internet and exposed to scanning and unauthorised access attempts. Modern ANPR platforms connect cameras to the cloud over outbound connections through a private APN – there is no technical requirement for the camera or router to be publicly addressable. Millbeck does not recommend public IP SIM cards for ANPR deployments.
Aggregated data bundles
For operators and installers managing multiple cameras across one or more sites, an aggregated data bundle pools allowance across the entire fleet. Low-traffic cameras draw less; high-traffic cameras draw more – without any individual camera hitting a hard cap while others have unused allowance. Billing consolidates to a single monthly invoice with fleet-wide usage visibility.
How Much Data Does an ANPR Camera Use Per Month?
Data usage depends on traffic volume at the site, whether the system transmits compressed plate read events only or also uploads associated video clips, and how frequently the camera polls its management platform for hotlist updates and configuration synchronisation.
Approximate monthly data usage guide per camera:
Low-traffic site, plate read events only (e.g. quiet access control point): 1-2 GB
Medium-traffic car park or compound entrance: 2-5 GB
High-traffic enforcement camera or unit uploading video clips: 5-10 GB
These are approximate figures. Confirm expected usage with your camera platform provider before selecting a bundle. Aggregated bundles reduce the risk of any single camera running short mid-month.

Frequently Asked Questions
Does the SIM card go in the camera or the router?
It depends on your system. If the camera has a built-in 4G modem (for example, a Suilvision Lightning 5X, Milesight solar ANPR unit, or WCCTV redeployable tower), the SIM goes inside the camera. If the camera is a standard IP unit connecting via PoE to a separate router in a cabinet – which is the most common setup for fixed car park and access control installations – the SIM goes in the router. Call Millbeck on 0300 124 6181 if you are unsure which applies to your installation.
What is the best SIM card for an ANPR installation?
For most UK ANPR deployments, the correct choice is a multi-network roaming SIM with a private IP address on a dedicated private APN. Multi-network roaming provides reliable connectivity regardless of which network has the best coverage at the site. The private APN routes all traffic through a secure closed network, keeping plate read data off the public internet and allowing secure remote access to the camera or router. View Millbeck IoT SIM options.
Can I use a standard consumer SIM in an ANPR installation?
Consumer SIMs are locked to a single network, carry no static IP address, and are not built for always-on machine-to-machine use. They will often connect initially but will fail in areas of poor coverage for that specific network, will not support private APN routing, and will not provide a consistent address for the back-office platform. For any professional ANPR installation, an IoT SIM on a private APN is the correct choice.
What data bundle size do I need?
For event-triggered plate read data with no video upload, 1-2 GB per camera per month covers most low-to-medium traffic sites. For cameras uploading video clips or covering high-traffic locations, budget 5-10 GB. For multi-camera deployments, an aggregated bundle across the fleet removes the risk of any individual camera running out of data while others have spare allowance.
Does Millbeck’s SIM work with Unity5 Zatpark?
Yes. Zatpark is a cloud-based platform that receives outbound connections from ANPR cameras and routers over standard HTTPS. The Millbeck private APN provides outbound internet access through a secure closed network, which is fully compatible with Zatpark’s connection model. Millbeck has supplied SIM connectivity for numerous Zatpark-based installations. Call 0300 124 6181 to confirm configuration details for your specific setup.
Do you supply SIM cards for redeployable ANPR systems?
Yes. Redeployable ANPR towers and portable units are one of the most frequent use cases for Millbeck’s multi-network roaming SIMs. Because the system moves between sites, it needs a SIM that automatically connects to the strongest available network at each new location. The same SIM and data bundle travels with the unit, with no need to reconfigure or swap SIMs between deployments.
