These are often some of our favourite enquiries:

"This might be a long shot, but can you find...?"

We work with customers looking for all sorts of electronic products, including items outside our standard range. If we can't supply something directly, our sourcing service means we can look at our wider manufacturing and supplier network to see what's available.

Sometimes we find exactly what they're looking for, sometimes we find a suitable alternative.

We can't promise we'll always be able to find it (and we can't help with toys, clothing or ceramics), but it's always worth asking!

Some environments need to stay within a particular temperature range, but checking them manually throughout the day isn't always practical.

Keystone's NetzHome WiFi Temperature Sensor can monitor temperatures remotely and send an alert to your smartphone or tablet if the temperature rises above or falls below your chosen limits.

It can be useful in areas such as greenhouses, storage rooms, w**e cellars and other temperature-sensitive environments where an unexpected change could cause a problem.

It's a straightforward way to keep an eye on temperature without needing to be there in person.

If you'd like to find out more or order one of our Netzhome Temperature Sensors, please get in touch.

The products that often receive the least attention are usually the ones expected to perform perfectly every single day.

Whether it's a monitoring device, signalling equipment or alarm notification system, reliability isn't a bonus feature, it's essential.

In our latest article, we explore why compliance and reliability remain two of the most important considerations when selecting products for modern security systems.

If you're specifying equipment or designing systems, it's well worth a read.

Small problems become expensive when nobody knows about them.

💧A water leak overnight.
❄️A freezer failure over the weekend.
🔔An alarm activation while the premises are empty.

The longer these events go unnoticed, the greater the potential cost.

Connected monitoring systems don't just improve security, they help businesses respond sooner, reduce downtime and protect valuable assets through real-time alerts. Early notification is a key benefit of modern connected safety systems.

To find out more, get in touch or take a look at our website.

A small leak can quickly become a big problem.

Whether it's a plant room, server room, commercial premises or residential property, early detection can make all the difference.

Our flood detection sensors are designed to identify the presence of water as soon as it's detected, allowing connected systems to trigger an alert before significant damage occurs.

They're ideal for applications where even a small leak could result in costly repairs, downtime or disruption.

Typical applications include:
💧 Plant rooms
💧 Boiler rooms
💧 Commercial buildings
💧 Residential properties
💧 Data and communications rooms

Combined with our signalling and notification products, they provide a simple but effective way to improve monitoring and reduce risk.

To find out more about our flood detection solutions, get in touch with our team.

Going away this summer? Opportunists are ready.

Sites are quieter, fewer people are around, and systems that normally sit in the background suddenly become more important. If something goes wrong, the only indication might be whether a message gets through or not.

It’s a good reminder that alarm communication isn’t just about normal working conditions. It needs to hold up when nobody is there to notice a problem directly.

That’s often where the difference between a landline-based setup and a GSM unit becomes more obvious, particularly in locations where infrastructure isn’t always consistent.

Whether it's receiving instant alerts from an alarm system or monitoring environmental conditions remotely, smart notification technology provides reassurance when you're away.
It's one of the reasons connected security continues to grow in popularity.

To find out more, or to check that your security alerts are fit for purpose, get in touch.
