Introducing the NEXSMART™ GUARDIAN 4G – Our latest innovation in security alarm systems, now with inclusive 4G capabilities!

The NEXSMART™ GUARDIAN 4G is more than just a standard alarm system. It’s a comprehensive, smart security solution designed to give you quick and easy theft and burglary protection of your home, workplace, or what matters most to you.

Our NEXSMART™ GUARDIAN 4G stands out from the crowd with its integrated Wi-Fi and GSM technologies. This dual-layer approach ensures an uninterrupted, robust, and seamless security experience and comfort.

The NEXSMART™ GUARDIAN 4G doesn’t rest on laurels of Wi-Fi capabilities alone. Its impressive functionality extends to an integration of GSM technology, providing a reliable backup communication route. If your Wi-Fi service ever fails, it will not have an effect on your alarm system. In case of a Wi-Fi crash, the GUARDIAN 4G will automatically switch to using the SIM card for communication – ensuring that you’re alerted promptly in case of a crisis.

When you employ a NEXSMART™ GUARDIAN 4 alarm system, you gain the benefits of a fast local network connection via Wi-Fi. This feature provides a real-time monitoring and control capabilities, ensuring that your home is always looked out for. In addition, it facilitates direct push notifications to your mobile phone, through our Smart Life App (which of course is free), keeping you apprised of the situation at any time!

With the NEXSMART™ GUARDIAN 4G, peace of mind is just a touch away. Its all-round security features ensure that your safety is never compromised, giving you a resilient protection strategy that adjusts according to your needs!


The NEXSMART™ GUARDIAN 4G is simply a revolution in theft and burglary protection. Say goodbye to the complexities of extensive cabling and complicated coding configurations associated with traditional security- and alarm systems.

When it comes to installing your GUARDIAN 4G, it is a straightforward process. Simply position it on any wall you’d like, connect with the Smart Life App, and simply add the sensors you want. It has never been easier or simpler to secure and protect what matters most to you.

But that’s not all. The NEXSMART™ GUARDIAN 4G functions hand in hand with our surveillance cameras to further boost your home security. Every aspect of our wide range of products and alarm systems are designed to work together accessible through the same App. This cohesive integration simplifies the security process, making protection of your home even easier.

GUARDIAN 4G also gives you easy access to smart automations. In the Smart Life App, you can set up your surveillance cameras to act as sensors for your alarm system, or conversely, use your sensors as surveillance tools. This two-way functionality adds another layer of flexibility to your alarm system. The NEXSMART™ GUARDIAN 4G is not just an alarm system – it’s a revolution in home security!


With a NEXSMART™ GUARDIAN 4G alarm system, you are always present where you worry the most.

With our App (which is of course free) you have direct 24/7 access to your alarm system – no matter where you are in the world. This applies whether you are at work, on the train, or have gone on holiday to the Maldives.

From the App, you have direct access and full control over your alarm system. Get an overview of all sensors, check battery levels, or view the log of activations. Of course, you also have access to the very basic functionalities – such as activating/deactivating the alarm system!


A NEXSMART™ GUARDIAN 4G alarm system is not connected to a useless alarm system whose sole purpose is to call you and tell you that your alarm is activated. Our GUARDIAN 4G alarm system alerts you directly on your mobile phone via Push Notifications through text message, or through direct call to your phone when the alarm is activated. You can add up to 5 phone numbers in case the first added phone number is not able to pick up the phone – the GUARDIAN 4G will then continue to call the next in line and so on.

In the event of, for example, a power failure or a low battery on an associated sensor, you will receive information directly in the Smart Life App. In addition, your GUARDIAN 4G is equipped with a built-in 80dB Siren that will howl when the alarm is activated.


The most unpleasant thing that can happen is getting unexpected visits while sleeping.

Our NEXSMART™ GUARDIAN 4G alarm system has intelligent home protection that can be activated while you are present. Your sensors are simply divided into zones so that e.g. the door/window sensors are fully activated while any PIR motion sensors are disconnected. Thus, you can safely go to the toilet at night, without activating the alarm – but if there are intruders who are planning on going through a window, the alarm will be activated.


You can share access to the alarm system with anyone you want. There is room for unlimited numbers of users in the App, so your entire family or workplace can access the system, directly from their mobile phone.

You can even share the system temporarily, with neighbors or friends, who can get control of your alarm system while you're away on vacation or something similar.


NEXSMART™ GUARDIAN 4G has a built-in backup battery, which ensures that the alarm system remains fully activated for up to 8 hours after a power outage.


An alarm system is only as effective as the sensors to intercept the intruders. For a NEXSMART™ GUARDIAN 4G Alarm system, you have a wide range of possible sensors.


Magnetic sensors are used to secure doors, windows, and other entrances based on "opening". The sensor, for your NEXSMART™ GUARDIAN 4G, is easily mounted with included double-per-adhesive 3M and activates when the two parts of the sensor are removed from each other.

Infrared motion sensor, for your NEXSMART™ GUARDIAN 4G, which can cover a larger area with just a single sensor. This sensor is particularly suitable for covering a larger area that is at risk of intrusion, without having to open doors or windows.

You can read more about the [Large Motion Detector] here


Small infrared motion sensor, for your NEXSMART™ GUARDIAN 4G, which can cover a more specific area with a single sensor. This sensor is particularly suitable for covering a smaller area that is at risk of intrusion, where doors or windows must be opened.

The smart mounting brackets and their smaller size make it suitable for hanging in e.g. a corner or at foot height.

You can read more about the [Small Motion Sensor] here


With a remote control for your NEXSMART™ GUARDIAN 4G, you have features like reinforcement, disarming, SOS, and shell protection at your fingertips.

It's small and portable, perfect for a key bundle, so you can easily and simply turn your GUARDIAN 4G on or off without having to bring out your phone.

Should the accident be out and you need to alarm, you can use the SOS button on the remote control to start the alarm, as well as inform them with the app that the SOS button is pressed.

With a Keypad for your NEXSMART™ GUARDIAN 4G, it can’t get any easier or more secure. With your very own changeable and personal code, you can easily and securely connect or disconnect the alarm system completely without the use of your Smartphone.

It only takes a few seconds to secure your home from burglary - disarm, arm, or home arm to secure what you care about most.

You can read more about the [Keypad] here


With an RFID tag, for your NEXSMART™ GUARDIAN 4G, you can connect or disconnect your alarm system even faster and easier. With a single swipe, you can connect, disconnect, or home arm your alarm system.

You can buy multiple RFID tags and give them to your family members, roommates, or colleagues. It does not get much easier!

You can read more about the [RFID Tag] here


With an indoor siren for your NEXSMART™ GUARDIAN 4G, you can be absolutely sure that if your alarm goes off it will not go unnoticed.

When the thief activates the alarm, your indoor siren will blow out over 100 dB of the siren which is guaranteed to alarm everyone nearby, e.g. your neighbors. Even if the thief finds the siren and pulls it out of the power socket, the siren's built-in battery will take over and the siren will therefore continue to howl until you disconnect the system from your phone.

Floods can cause devastating damage to your property, especially when they go unnoticed. They often occur in areas of your home or business that are infrequently visited, such as the basement, where the damage can be extensive.

With this sensor, you'll receive instant notifications on your phone as soon as a flood is detected, allowing you to take immediate action to prevent further damage.

The NEXSMART™ FLOOD SENSOR is part of the GUARDIAN 4G eco-system, which allows you to customize other alarms or sirens to warn you if the sensor has detected something. This way you can be alerted in multiple ways and from multiple locations in case of a flood.

We know how frustrating and costly a flood can be. That's why we're confident that the NEXSMART™ FLOOD SENSOR will protect you in the future and give you peace of mind during stormy seasons. Don't wait around for the next flood to act!

The NEXSMART™ OUTDOOR SIREN – a perfect addition to the ultimate security solution. Our siren actively protects your property by alerting you and your neighbors in case of an emergency. With its loud 110 decibel alarm and flashing strobe light, it cannot be overheard or overlooked. The outdoor siren is part of our GUARDIAN 4G eco system so you easily can tailor the security system that best protects you.

Since the siren is one of the first lines of defense, we made sure to tamper-proof it. Furthermore, the outdoor siren has a back-up battery which only makes it so much more reliable. Sleep peacefully knowing that you, your loved ones, and your property are protected.

Gas is a vital and practical component in many households. Yet, gas leaks can be incredibly dangerous and pose an unseen danger to the safety of you and your loved ones. Even a slight gas leak can lead to severe consequences, so it is essential to detect it as early as possible.

The NEXSMART™ GAS SENSOR is also part of the GUARDIAN 4G eco-system, allowing you to customize other alarms or sirens to warn you in case of a gas leak, ensuring that you're alerted in multiple ways and from multiple locations.

The gas sensor can also be connected to electrical gas valves, enabling it to automatically turn off the gas in case of a leak, providing an added layer of protection for your home.
