If you need to protect valuable assets in locations that aren’t always staffed, you need a solution that continuously monitors conditions like temperature, humidity and power failure. Wireless cellular monitoring systems enable you to check on your property from anywhere, at any time.
These systems alert you to issues such as extreme temperatures or leaks before they become costly problems. You don’t need an internet connection or phone line. With a cloud-based system that uses cellular connectivity, like the Sentinel PRO, you can monitor your property 24/7 with real-time visibility.
How Cellular Monitoring Systems Work
Cellular monitoring systems function similarly to autodialers and Ethernet-based systems. They collect data, such as temperature and humidity, from sensors and transmit it to the cloud using a cellular connection. In fact, the main difference in these systems is how the devices transmit sensor readings. Auto dialers send through a traditional landline. Ethernet-based systems send through a local area network with and Internet connection.
While there is usually a monthly cellular service fee, it is often more cost-effective than installing and maintaining a landline or running Ethernet cables. You also don’t have to worry about SIM cards, overages, and pricing structures. Choosing a cellular device makes your monitoring system more flexible because it doesn’t depend on existing infrastructure
Key Reasons to Go Cellular
There are five main advantages for choosing a cellular monitoring system:1. Internet connections can go down during a power failure.
Most internet setups depend on local power to keep modems and routers running. When the power goes out, your connection usually goes with it. Even short disruptions can create a gap in monitoring when you need it most. Cellular systems continue to transmit data during these disruptions, helping ensure continuous visibility of conditions.2. Remote locations don’t have internet access.
Some remote or rural locations simply don’t have reliable internet. In many cases, installing internet infrastructure isn’t realistic because it can be expensive or impractical. Cellular monitoring systems address this challenge by using existing cellular networks, making them ideal for off-grid or hard-to-reach locations.3. Landlines are becoming extinct.
Traditional landlines are becoming obsolete as providers shift to modern technologies. Service is becoming less common, maintenance is declining, and reliability is declining. Because of this, landlines are no longer a practical choice for modern monitoring.4. High-security facilities don’t allow Ethernet-based devices on their network.
In high-security environments like data centers, government buildings, or regulated industries, IT teams tightly control what can connect to their networks. Adding third-party monitoring devices is often restricted due to security concerns. Cellular systems work independently of these networks, making them easier to deploy in secure locations.5. Running cable and phone line isn’t physically practical or affordable.
Installing Ethernet or phone lines can be difficult, especially over long distances, across rugged terrain, or through existing structures. Trenching, wiring and other labor costs can add up quickly, making wired solutions expensive and time-consuming. Cellular systems eliminate the need for physical connections, allowing for faster, more cost-effective deployment.Common Applications
Cellular monitoring systems are used in a variety of applications, including data centers, water and wastewater treatment plants, medical cold storage, cannabis growing facilities, livestock operations, HVAC systems, greenhouses and food and beverage cold storage. They are especially valuable in the following scenarios:• Multi-site facilities – Enable centralized monitoring across multiple locations without needing separate internet connections at each site.
• Remote or hard-to-wire locations – Ideal for areas where running Ethernet or phone lines is impractical or cost-prohibitive.
• Backup monitoring for critical infrastructure – Provide continuous operation and real-time alerts if the primary internet or network connection fails.
Ensuring Best Cellular Coverage
Cellular coverage from major carriers like AT&T, Verizon and Rogers reaches most of the U.S. and Canada. However, spotty coverage can be almost as problematic as having no coverage at all. If the signal isn’t strong or consistent, your monitoring system may struggle to connect, meaning you won’t receive important sensor data or critical alarms when you need them.
Several factors can affect cellular reception. Network congestion and tower placement are two of the most common. Cellular coverage relies on a network of cell sites, each with its own tower and base station, typically covering about 10 square miles. Ideally, these coverage areas overlap to ensure a seamless connection. However, when there are gaps between towers, signal loss can occur. As you move away from a tower, signal strength naturally weakens.
Because of this, it’s important to evaluate coverage before choosing a cellular monitoring solution, especially for remote locations. Conducting upfront research helps ensure reliable performance and prevent connectivity issues.
Here are a couple of websites that can help you determine which carrier will provide the best coverage for your area:
cellmapper.net
CellMapper is a powerful tool for locating 2G, 3G, 4G, and 5G base stations. It collects signal strength and network data from users' devices to map the locations of cellular base stations and their coverage areas. This data is sent to CellMapper’s servers, where it's processed and displayed on a Google Maps-based interface, accessible through both the app and the website.
For best accuracy, measurements should be made in open areas with minimal obstructions. In urban settings, some signal obstruction is expected. Users are encouraged to move in half to three-quarter circles around suspected tower locations to improve mapping accuracy. Data can be uploaded in real time or submitted manually after collection.
How to Strengthen a Weak Signal
If your area is on the edge of cellular service, you may want to consider adding a high-gain antenna to your monitoring system. The antenna can be mounted on the outside of a building or enclosure. In addition to reducing interference from the structure, a high-gain antenna can help strengthen and stabilize the cellular signal.
Wireless cellular monitoring systems provide a reliable and flexible solution for protecting assets in remote or unattended locations.
With fast alerts by text, email or phone, plus cloud visibility and data logging options, you can build a monitoring setup that fits each site. Each system helps protect assets, reduce downtime and enable faster response when conditions change.
