The company designs and manufactures its own covert cameras, apps and supporting technology for professional investigators, surveillance teams, law enforcement organisations and councils.
Its equipment can be deployed for both short-term and long-term operations in urban, rural and remote locations.
The Covert Group has worked with KeySIM for four years, and its connected equipment is now used by hundreds of private investigators.
Reliable connectivity is vital during surveillance work. Authorised users must be able to access footage, manage cameras and respond to changing operational requirements without visiting the deployment site.
However, covert cameras are often installed in places where fixed broadband or Wi-Fi is unavailable. Mobile coverage can also vary significantly, making a SIM card tied to a single mobile network unsuitable for many operations.
The Covert Group selected KeySIM’s unsteered multi-network IoT SIM, which can connect through Vodafone, O2, EE and Three in the UK, as well as participating networks overseas. This gives deployed equipment a better opportunity to establish and maintain a mobile connection, even when the strongest network cannot be identified beforehand.
KeySIM’s cards are installed in Teltonika routers connected to The Covert Group’s cameras and applications. Authorised investigators can use the KeySIM VPN and the SIM’s private IP address to access and control the router and associated equipment remotely.
Teltonika routers can also receive SMS commands, providing an alternative way to control or reconfigure equipment if the normal data connection becomes unavailable.
Another important consideration is the possibility that covert equipment may be lost, damaged or discovered during a deployment. KeySIM operates without a minimum contract, enabling The Covert Group to cancel a subscription immediately if a camera or router cannot be recovered.
Vernon Griffiths, founder of The Covert Group, said connectivity was a critical part of the company’s complete surveillance system.
“If equipment loses its connection at the wrong moment, vital footage can be lost or become inaccessible, which can have serious consequences for an investigation,” he explained to That's Business.
Graham Robinson, Managing Director of KeySIM, said the combination of multi-network access, secure VPN connectivity, private IP addresses and SMS control gives investigators several ways to communicate with deployed equipment.
For The Covert Group, bringing together purpose-built cameras, supporting applications and flexible connectivity provides surveillance professionals with a practical system designed for the unpredictable conditions encountered during real-world investigations.
