What We Do
Our company believes that security should be a priority for any business. But we also believe our security solutions can increase your return on investment. That’s why we specialize in affordable security solutions that increase ROI for every business. Our team of experts will work to identify the areas of your business most at risk and develop a customized alarm system to address those risks. We’ll also work with you to implement security measures that will help you to save money in the long run.
Video Verification Alarm Systems
Need quicker police response? With our video verification alarms, this is possible. These systems send a live video feed to a monitoring center whenever your alarm is triggered. This way, the police can see footage of the break-in in progress, confirm whether it’s an intruder or not, and dispatch officers to the scene immediately to apprehend the suspects.
Avoid taking necessary action.
The experience of getting a security alarm only to find out that it was a false alarm is as bad as it gets. This can be stressful and unnecessarily costly, especially if you have to alert your team or the authorities by yourself. Nexlar’s video verification alarm systems provide a solution to this problem. By sending a live video feed to the monitoring center, these systems allow operators to verify whether an alarm is real or not. This means that you won’t be wasting your time (and money) on false alarms. Call us to get a free, no-obligation quote.

Wireless Security Alarms

Detect doors opening, vehicles, smoke, and more with our wireless security alarms. Running a highly productive business comes with a lot of responsibility. We understand that. We also know that the last thing you want to do is spend more money than you need to on physical security guards to alert you each time someone is trying to access your premises illegally. Our state-of-the-art sensors can detect cars, motorbikes, and pedestrians approaching your property or specific parts of your premises, giving you plenty of time to take action. And because our systems are wireless, they won’t negatively impact the look of your commercial building.

Smoke And Carbon Monoxide Alarms

Get notified at the first sign of smoke. This will give you and your employees and customers enough time to evacuate the premises safely. We can also provide alarms that can detect carbon monoxide and reduce the risk of gas poisoning. If you manage a factory or warehouse in Houston, TX, call us for more information about our smoke and carbon monoxide alarm systems. You won’t regret it. We promise.

Where do you want your alarms placed? Outside doors and windows or in storage areas? Our team has your back. With our expertise, there’s nowhere we can place your alarm system, and there’s no configuration we can’t do. We can mount them on door frames to make it easier for you to know when someone tries to access a specific room. Contact Nexlar’s professionals to learn more about our alarm installation services.
Your business is growing, and you may need to add more alarm systems in the future. Our alarms are designed with this scalability and flexibility in mind. Adding new sensors and devices to the system will be easier and save you costs on buying new whole systems.
Siren volume alarm control/disable functions.
How loud do you want your alert to be? Do you want your alarm completely silent? We’ve got you covered. Nexlar’s alarms allow you to determine how loud the siren should be and whether or not you want it disabled.
Built-in backup batteries
If there is ever any power outage, you can count on Nexlar’s alarms to stay fully operational. Their backup batteries are quick to kick in and keep the systems running. And if an intruder tampers with the wiring, you can count on these backup batteries to keep the system operational long enough for the authorities to be notified.
Can notify up to 5 separate numbers

Don’t get stuck with an alarm system that can notify only one number at a time. Technology has advanced way too much for that. With Nexlar’s alarms, rest assured that up to 5 numbers will be notified in the event of an emergency. Whether it’s a fire, break-in, or medical emergency, our alarm systems are designed to get help to you fast. Even if that means notifying the police, fire department, or security staff at once, and because we use the latest technology, you can be sure that our alarm systems are reliable and easy to use. Get in touch with our intrusion system installers in Houston, TX, to learn more about our multi-number alarm systems.

Smartphone app access

Arm and disarm your alarm systems at any time via a mobile application. With this web-based application, you can check the status of your sensors and even view live footage from anywhere in the world. Alfred360 also allows you to set up custom alerts and notifications, so you will always be updated when the setting you configure is met. Plus, this application is backed by 24/7 customer support and a security team that can configure it to work with already existing security systems like access control gates and video surveillance cameras.

Solar-powered options available
Are you looking for alarm systems that are environmentally friendly and can help you keep your business’s overheads at a minimum? Consider Nexlar’s solar-powered alarm systems. These systems will keep your business safe as they are reliable since they aren’t subject to the same power fluctuations that can occur with battery-operated alarm systems. They also do not require any wiring, and as a result, they’ll be the best bet for commercial property managers looking for a clutter-free and reliable intrusion detection system.
Motion detection
Our alarm systems have motion detection capabilities that can trigger the alarm in the event of suspicious activity. They use sensors to detect movement and then send an alert to the monitoring center. This allows our trained professionals to assess the situation and take appropriate action quickly. The motion detection feature can also be used to trigger cameras so that your monitoring team can get a clear picture of what is happening. This helps us to more quickly and effectively respond to any potential threats.

That way, you can ensure your system is installed correctly and won’t have any problems connecting. So, if you want to keep your property safe with a hassle-free method, choose our alarm systems.

Additional Accessories

Transmitters and receivers

if you need new transmitters and receivers for an existing alarm system, we’ve got you covered. The transmitters send out a signal that the receiver picks up. If the receiver does not pick up the signal, the alarm is not triggered. The transmitter can be placed in many locations, such as on a door or window or even in a hidden location. The receiver can be placed in several locations, such as on a wall or shelf. The transmitters and receivers can be used in conjunction with each other to create an effective alarm system.

additional-accessories-installation Houston Alarm Companies
Stay connected and in control. With our remotes for alarm systems, you can arm and disarm your system from anywhere. You can also receive signal alerts if there’s an intrusion.
Timer modules
At Nexlar, we understand that sometimes components break and may need fixing before the whole system fails completely. The timer modules we carry help to solve this problem by automatically replacing the batteries in the alarm system. This way, you won’t ever have to worry about your alarm system going off in the middle of the night unnecessarily.
Trigger modules
If your current alarm system has an old or faulty trigger module, it may be the right time to switch to Nexlar’s trigger modules. They’ll ensure that the alarm is only triggered when there is an actual emergency. This will reduce false alarms, which can be both disruptive and costly.
If you need to replace your antenna or upgrade your antenna to capture and detect intruders over a wider range, depending on the alarm system you have, we can help. The antennas we have send out a signal that is reflected off of objects in the environment. When the signal is reflected, it is received by the antenna and analyzed by a computer. If the signal is distorted, this can indicate that an intruder is present. Call us for more information.
