Welcome to Voneus Network Managed Services


In February 2018 Voneus acquired Lde Smartalarms Limited, a specialist provider of connectivity and security services to various companies and hundreds of locations throughout the UK.

By joining forces we can utilise our existing experience in delivering specialist wireless connectivity and broadband services to the public within a private networking sphere.  

The combined company, named “Voneus Managed Services” can now offer a number of additional services to our customer and these are outlined below.

CCTV services

At Lde, we have been installing, maintaining and monitoring CCTV systems for over 10 years.

We approached the CCTV market from a data communications background after a request from one of our existing customers to monitor their cameras as well as their network. We feel this gives us a big advantage over most of our competitors when designing and installing new systems.

We specialise in monitored CCTV using our own developed SmartAlarms systems, with 24/7 in-house monitoring staff.

About us

At Lde (aka Voneus Network Managed Services) we have been providing Managed Digital Services since our inception in 1988 and have been at the forefront of the data communications industry ever since.

Over that time we have been pioneers of mobile IP, IP CCTV and also VoIP telephony, offering all three aforementioned technologies to our customer base for over 10 years; much longer than the vast majority of our competitors. We also continue to offer various historic protocols which allows us to support a vast range of different environments and infrastructures.

Our notable achievements include being responsible for the first ever landing of a Eurofighter Typhoon on a civilian airfield, after working closely with the MOD to provide them with an appropriate secure data connection to upload the planes telemetry, something which had never been achieved before.

We are experienced in managing networks of over 1,000 devices in places which include major international airports such as Gatwick and Stansted, and also provide stable, secure data connections for a host of Formula One teams during in-season testing, allowing them to analyse data at their team headquarters in real time rather than having to wait until they return.

Our SmartAlarms monitored CCTV system has been developed over the last ten years from a data communications point of view and is now in its fourth iteration, taking advantage of the latest in IP CCTV technology.

Network Audit and Advice
At Lde, we are more than happy to come and perform a full audit of any existing network. This will allow us to report back any potential flaws or weak spots, and how best to overcome them. One of our biggest strengths is our ability to learn and understand the exact requirements and working practices of each client, and tailor our services and advice accordingly. We therefore will not advise on any measures that we feel to be unnecessary for your specific needs.
Business Critical Connections and Leased Lines
We understand better than most that these days the communications infrastructure is essential to the success of any business. We can offer a variety of different services if you cannot risk any downtime from your network, phones or internet. One of these services is our leased lines. We can offer dedicated, business critical circuits at extremely competitive prices, either as part of a WAN or as a standalone connection. Please feel free to get in touch to see what we can offer if you rely solely on your communications infrastructure.
Onsite and Cloud Based Data Storage
Lde can implement, support and manage a wide range of both onsite and cloud based data storage services. We specialise in “real” disaster recovery. If you rely on being able to quickly access your data, even in an emergency, then we can design a data storage system to meet your exact requirements. Whether that be a simple file server located in your office, or a host of shadow and backup servers located in different data centres, we can guarantee the kind of security and back up that you require.
Structured Data Cabling
We have a team of experienced full time field engineers that can carry out new installations, audits of existing installations and both basic and in-depth fault diagnosis on any kind of data infrastructure, from internal telephone cabling, to CAT5 and CAT6 data cabling, fibre optics and much more. We are happy to tackle projects from adding single network points to an existing installation to planning and installing entire structured cabling infrastructure for new buildings or refurbs. We only use the best materials with our physical installations to ensure you get the best possible performance and also integrity from any cabling installation.
Data and Telephony infrastructure extension
Whether it be extending a telephone line to a new room, or extending a LAN to incorporate a new building or site, we have the expertise to extend any kind of network infrastructure for you. We have been doing such works for over 15 years, through using either existing copper cable where available, laying new copper or fibre optic cable, or installing high speed professional wireless links. Wireless links are a speciality of ours, and we have been installing them for our customers for over 10 years. We were one of the first to offer the service when the technology first developed and have stayed at the forefront of the industry ever since. These can often represent a huge saving over laying new cables, as there is much less labour involved.
3G, 4G, Satellite and Rapid Deployment of Services
We have been pioneers of Mobile IP for the last 15 years, and currently offer various types of mobile internet. We can utilise 3G, 4G and Satellite connections amongst others to offer internet services in environments that otherwise could not support them. These services are also extremely useful for rapid deployment when a new location is being commissioned, as it can often take many weeks for a traditional connection to be installed. They are also perfect for temporary environments such as cement plants, building site offices and much more. We are also specialists in integrating these mobile internet connections with an existing WAN.
