FREQUENTLY ASKED QUESTIONS

Modern remote sites are hard to reach reliably and securely. Cellular and Starlink connections sit behind carrier grade NAT, so you cannot natively run port forwards, VPNs or allow listing, and the public IP can change without warning. Fixed line connections drop, corporate IT teams will not allow third party CCTV on their network, and exposing devices through open ports creates real cyber risk. Netcelero solves all of this. We give you a fixed, secure public IP on any connection, automatic failover when a link drops, and a private path to your site that does not require any changes to the customer’s network. Your sites stay reachable, your data stays protected, and your team stops fighting connectivity issues.

We have four solutions to choose from.

The i-spi is an affordable plug and play device for remote CCTV monitoring over a single connection, with port forwards and OpenVPN access.

The i-ctrl is the higher tier device, supporting multiple connections (fibre, DSL, 4G, 5G, Starlink) with automatic failover of a static public IP, plus Layer 2 and Layer 3 VPNs, VLANs and Dual Static IP for network segmentation.

Secure Link is our IPSec based solution for critical infrastructure, delivering end to end encryption from remote sites to your HQ or SOC, even over cellular or Starlink.

The soft-spi is a software only version of the i-spi for customers who prefer to use their own hardware.

Contact our support team and we will help you pick the right fit for your site.

Yes – we run dual data centres in Dublin and Amsterdam, with automatic failover between them, and we own our IPv4 and IPv6 address space. This gives our customers more stability, faster issue resolution and better control than reselling another provider’s infrastructure.

Yes. Our solutions are technology and operator agnostic, so they work across fibre, DSL, 4G, 5G and Starlink, on any ISP or mobile network. Whichever connection you have, Netcelero can secure it, provide a static public IP and keep it resilient.

Yes. Netcelero is deployed worldwide on any new or existing connection. We keep customers securely connected across Europe, North America and Asia Pacific, and our software is compatible with all the major mobile networks. Features such as geo locking let you define which countries are allowed to connect to your site remotely, keeping your perimeter tight.

Your real world speeds are largely determined by your underlying connection. Netcelero is built to make the most of whatever link you have available, whether that is fibre, 5G, 4G+ or Starlink. For 4G and 4G+ deployments, we recommend a high gain omni antenna to maximise throughput. Our technical support team are experts in mobile connectivity and can advise on the right setup for your site to get the best performance.

Yes, Netcelero is perfect for remote CCTV monitoring. The i-spi was designed specifically for this use case, providing up to four configurable port forwards and a static IP on any connection, even a single 4G SIM. It integrates seamlessly with Sentinel and Immix, giving alarm receiving centres an instant, secure path to site.

The i-ctrl is our higher tier option, supporting up to two cellular connections (4G, 4G+ or 5G) alongside fibre, DSL or Starlink, with automatic failover of a static public IP across connections. For maximum resilience on cellular, we recommend SIMs from two different mobile networks. If the site only has coverage from one network, we can still provide resilience using a second SIM on the same network, on a lower technology – eg one on 5G and one on 4G.

The i-ctrl supports multiple connections, up to six depending on the model. Our solution is technology and operator agnostic, so you can combine any mix of fibre, DSL, Starlink, 4G, 4G+ or 5G, from any ISP or mobile network. Your static public IP automatically fails over between connections, so your site stays reachable no matter which connection is active.

The i-ctrl is a pre-configured device running hardened Linux with an integrated firewall. It sits on site, combining the latest processors and wireless modules with power efficient technology, and connects to our secure cloud network in our Dublin and Amsterdam data centres. Your static public IP is delivered from our network, so it stays the same regardless of which underlying connection is active, even when the active connection is 4G, 5G or Starlink.

The i-ctrl delivers a static public IP (or two independent static IPs if needed for network segmentation), encrypted transport, automated monitoring and alerting, SIM data pool management and a rich analytics portal. Our cloud services run on our own IP address space from dual data centres in Dublin and Amsterdam. You do not need your own data centre or static IP allocation; we provide both as part of the service.

With cold failover, you lose your connection to cloud services while the system, or a staff member, switches over to the secondary connection, and failback is often unreliable. Netcelero’s failover is automatic and seamless, keeping your static public IP live on the backup connection within seconds. It is self healing and self protecting, so your connection continues in spite of an outage on the primary path, with no intervention required.

Load balancing splits traffic across two active connections, and if a session is in flight when a link drops, that session is often terminated. The i-ctrl uses hot failover rather than load balancing. Your static public IP rides on one active connection at a time; if that connection drops, the IP fails over to the backup connection automatically and seamlessly, and fails back when the primary returns.

This approach prioritises session stability and predictable routing, which matters for remote CCTV, VPN and VoIP services.

Your Netcelero Analytics Portal gives you live visibility of every connection at every site, wherever you are. You can nominate who to alert (by email or SMS) on the key performance indicators that matter to you, such as a link being down, a latency threshold being crossed, or power failing over to your on site UPS.

If you are managing multiple devices across different sites, our cloud based portal gives you remote visibility across your entire estate on one dashboard. You can see the status of every connection and network, availability, data usage and a wealth of analytics. You can apply data limits to any SIM, with alerts before you reach the allowance. Access is protected by multi factor authentication; contact our technical support team for your login details.

Yes, your telephone calls will be unaffected, and your DSL or fibre line will be optimised and secured, so you get more value from the link. Many businesses are paying for additional lines they do not need. Call our technical support team to find out how to get the most from the connections you are already paying for.

Yes, many customers run VoIP over Netcelero. Because our failover is seamless, VoIP calls can continue uninterrupted even when the underlying connection changes. Configuration varies by VoIP provider and SIP trunk setup, so please contact our support team and we will help you get it right.

Yes, Netcelero supports VPN traffic. Depending on your setup, your configuration may need a routed node at our end. Contact our support team and we will work with you to get it set up; VPNs are very much our speciality.

Yes, the i-ctrl can deliver Layer 2 or Layer 3 VPNs, so you can use discovery tools such as Hikvision SADP remotely, without needing to visit site. Importantly, Netcelero removes the inherent security risks of exposing discovery tools to the public internet, which have been used for both cyber espionage and criminal activity.

Yes. Call our technical team to discuss your requirements and hear about other challenges we have solved, from thermal imaging camera connectivity, to people counting at mass events on congested mobile networks, to proactive video monitoring for sea turtle conservation. Because we develop our own hardware, software and core infrastructure, we have the flexibility to deliver secure connectivity for bespoke projects.

The i-ctrl is available with 4G CAT 4, 4G+ CAT 12 or 5G modems, with the option of one or two modems per device. There is also a no modem version for customers using Starlink or fibre exclusively, which has a lower hardware cost. Your modem choice affects hardware pricing but has no impact on your monthly SaaS fee.

We use Telit modems as standard. Across our 12 years of simplifying secure connectivity, we have found them to be the most effective, resilient and reliable on the market, with strong global carrier approvals and long term firmware support, all of which matters for deployments expected to run for years without intervention.

Yes, port forwarding is supported and easy to manage. With the i-spi, the software scans the local network for devices, you authorise the device to connect to your NVR, add your port forwards (up to four) and you are done. Port forwards are always under your control via the Netcelero Analytics Portal. Secure CCTV connectivity has never been so simple or affordable.

Netcelero soft-spi is the software only version of the i-spi. If you already have suitable hardware and want the benefits of a static public IP with port forwarding and OpenVPN access, soft-spi can run on your existing device. Contact our support team to check compatibility and get started.

Easily, with Netcelero. Set your 4G connection on the i-ctrl to reduced usage mode, so it uses minimal mobile data when your primary connection is working. If the primary connection fails, your business stays online through the mobile link for as long as you need it.

You can manage SIM data usage from the Netcelero Analytics Portal, with alerts when a SIM nears its allowance or when an unusual spike occurs, which is often an early indicator of a primary link issue or malware. The portal provides live and historical data visibility across every connection, so you stay in control.

Reduced usage mode is one of our most popular i-ctrl features. In this mode, the 4G link sends only a small amount of keepalive traffic (around 90MB per calendar month) while your primary link carries everything else. If the primary link drops, traffic fails over to 4G automatically. When the primary returns, the 4G link drops back into keepalive mode. This hot failover and failback is completely seamless, and protects your data allowance.

Netcelero can optimise connection. Paired with a high gain omni antenna, 4G, 4G+ and 5G connections can see significant improvements in both speed and reliability. Our team can recommend and supply the right antenna for your site.

Standard 4G uses a single band at a time. 4G+ is enhanced 4G, using multiple bands simultaneously (carrier aggregation) to increase speed. 5G is the latest generation, offering higher speeds, lower latency and more capacity. The i-ctrl is available with 4G CAT 4, 4G+ CAT 12 or 5G modems. The right choice depends on local coverage and the speeds your site actually needs. Contact our support team for a recommendation.

Yes, Netcelero and Starlink are a great combination. Starlink satellites operate in low earth orbit, delivering latency of 25 to 50ms, far lower than traditional geostationary satellite. However, Starlink sits behind carrier grade NAT (CGNAT), so you cannot natively run port forwards, VPNs or allow listing, and the IP can change without warning.

Netcelero fixes this: we deliver a fixed, secure static public IP on any Starlink connection, so your systems stay reachable and stable. You can also combine Starlink with 4G or 5G on the i-ctrl for automatic failover, or run Dual Static IPs on a single device for network segmentation, for example SCADA on one IP and CCTV on another.

This is a common issue for system integrators, and the i-spi solves it. You have two options. Either deploy a 4G, 5G or Starlink connection with an i-spi; we provide the static IP and secure the connection, so you do not need any input from the customer’s IT team.

Or, if you want to use the customer’s existing internet, simply ask IT to allow outbound traffic from the i-spi. The monitoring centre connects to the NVR through the i-spi, the NVR sends SMTP alerts through the i-spi, and the customer’s corporate users connect locally as normal. Port forwards are always in your control through the Analytics Portal, so there is no waiting on a support ticket.

Yes. The i-ctrl supports a Dual Static IP configuration, allowing two independent static public IPs on the same device. A common use case is solar farms and critical infrastructure sites, where a SCADA network sits on one IP and CCTV operations sit on another, with complete logical separation. Both IPs can share a primary connection (for example Starlink) with automatic failover to 5G or 4G across both IPs, without user intervention. No additional hardware or complex routing required.

Yes, and this is one of our core strengths. Starlink sits behind carrier grade NAT, which means port forwarding, VPNs and allow listing do not natively work, and the IP can change without warning. Netcelero delivers a fixed, secure static public IP on top of any Starlink connection, so your systems stay reachable and stable regardless of what Starlink does in the background.

Yes. The i-ctrl, or i-spi, at each remote site can terminate a secure VPN back to a central i-ctrl at your HQ, creating a private multi site network over cellular, Starlink or fibre. Each remote site gets a private address range reachable from HQ, ideal for accessing CCTV, SCADA or PLC equipment. Firewall rules on the central device can prevent lateral movement between sites, and each remote site can still fail over between its own connections independently.

Yes. Renewable energy is a core focus for Netcelero, and we support solar farms, wind farms, hydro sites and utilities across the UK, Ireland and beyond. Our solutions keep SCADA, monitoring and CCTV systems securely accessible even in the most remote locations.

The Dual Static IP feature is particularly valuable for these environments, allowing SCADA and CCTV networks to be logically separated on the same device, with Starlink as the primary connection and 4G or 5G failover for carrier diversity. Our in house engineering team has deep expertise in IEC 62443 aligned architectures, so you can be confident your critical infrastructure is in safe hands.

Yes simply connect the i-ctrl to the WAN port of your own firewall and configure our public ip directly on your own firewall thus allowing IPSEC to anywhere over any connection type.

Yes. The i-ctrl supports VLANs, port isolation and, with our Dual Static IP feature, two independent public IPs on the same device. This means you can run SCADA on one logical network and IP, and CCTV on a separate one, with no routing between them. A clean, compliant separation on a single piece of hardware.

Netcelero supports VLANs and port isolation on the i-ctrl, which restrict devices to communicating only with their gateway. This limits the blast radius if a camera, NVR or other device is compromised, so an attacker cannot move across your network. Combined with regular firmware updates and the restricted remote access our solutions provide, this is a core part of a modern cyber hygiene strategy.

Secure Link is our IPSec based solution for critical infrastructure. It creates an end to end encrypted tunnel from each remote site back to your HQ, ARC or SOC through our Dublin or Amsterdam data centres, even when the underlying connection is 4G, 5G or Starlink.

Many critical infrastructure tenders require end to end encryption and multiple data centres; Secure Link meets both requirements, while still allowing your team to VPN into site for updates and diagnostics. Your remote sites stay protected from external access even on networks that cannot natively handle IPSec.

Call us on 1800 810 005 (IE), 033 0122 2640 (UK) or 857 4000 708 (US), or email [email protected], and we will have you securely connected in no time.

A Netcelero solution has two parts: a small intelligent device on site (the i-spi or i-ctrl) and our cloud network. The on site device slots easily into any network or comms cabinet and is online as soon as it is plugged in. Secure networking, ready to go.

For customers who prefer software only, soft-spi runs on your own hardware – contact us for supported third party models.

Netcelero is designed for easy deployment. If you have internet on site, the device can be slotted into your network, even by non technical staff, and is online immediately. Plug and play secure connectivity, with none of the usual complexity.

Netcelero is a Software as a Service (SaaS) solution. You purchase the on site device up front, then pay a monthly, quarterly or annual SaaS fee for access to our cloud network, including the static public IP, analytics portal and ongoing support. The i-spi is a lower cost entry option. Contact our team for a tailored quote.
