Are Wireless Home Security Systems Reliable?


Wireless devices are considered less dependable than wired ones in tech terms. But is it any different for security systems? Yes, indeed. In fact, all the best security systems for houses are wireless.

However, it doesn’t mean there are no potential reliability issues. They are discussed later. But the good part is one can manage those issues. There’s no stress if the best home alarm systems and cameras are purchased.

This article delves deeper into how wireless security systems work. So, take a look at the fruit of some testing and research.

Wireless home security systems: Advantages

Here are the advantages of wireless home alarm systems over wired devices. Before getting to the potential issues, take a glance at what’s good.

No wires, no risk of cut

If there are wires, burglars may cut them to disable the security systems. They could be cable internet or landlines wires or connect the control panel to sensors.

There is no need for such wires in wireless security cameras. So, bid goodbye to those wire-cutting burglars!

Monitoring remains uninterrupted

Most wireless security cameras and similar equipment have backup communications and battery backups. They keep the systems running during internet, power, or landline outages.

So, the purpose is 24/7/365 protection. With wired systems, the monitoring may dwindle because of interruptions in wire settings. Also, the burglars’ issue mentioned above shouldn’t be overlooked.

Installation is streamlined

Since these home security cameras and other devices are wireless, their installation is easy. In addition, many of them are DIY systems.

On the other hand, wired devices require professional installation. So, people who prefer DIY instead of the long installation process should go wireless.

Over-the-air updates

If a system is wireless, it updates its firmware over the air regularly and automatically. It means there is no need to update the home alarm systems manually.

Further, these firmware updates make the security devices less vulnerable to threats of security. Such a feature isn’t present in wired home security devices.

Access remotely

Wireless home alarm systems use either cellular signals or Wi-Fi to communicate. Both these methods allow for accessing the systems remotely using smartphones.

Receive alerts through apps and view the camera footage. Then, arm, disarm and manage the system accordingly.


DIY installation and customization go hand in hand. Even after setting up the wireless system, one can add sensors. The components can become a part of the wireless security cameras.

With professionally installed, wired systems, technicians need to visit the spot. Then, every time additional components are needed, one must call them.

Downsides of wireless systems

Problems with network connectivity

Home security cameras that heavily rely on the internet connection are wireless. Therefore, they require the vital availability of internet connections to report alerts.

But suppose the internet goes down. Then, these systems will not function. So, to avoid that issue with wireless security equipment, choose a cellular backup. One can go completely cellular as that is a wireless option.


When something is connected to the net, it becomes hackable. It includes wireless security cameras and alarms. Even though the chances of these devices getting hacked are meager, it’s still possible.

So, what is the way out? One can maintain the best digital security practices. Use two-factor authentication, strong passwords. Also, choose VPNs, antivirus software, and strong Wi-Fi encryption protocols. And there’s nothing to worry about!

Batteries may run out of juice

A smoke alarm will chirp when it runs on low batteries. But wireless sensors like door sensors and motion detectors will not. Sometimes, one can get a low-battery alert on the mobile app.

However, it’s important to remember to replace these batteries regardless of the notification. The good part is batteries last for many years. An example is Frontpoint. Its motion sensor batteries last for around five years!

Are wireless security systems better than wired ones?

Usually, wireless home alarm systems are recommended over wired ones. The former allows faster alert transmission. So, sensors, monitoring centers, and control panels that do not use wires are simpler.

But why would that matter? Every minute counts when there’s a burglary. According to studies, burglars can get in and escape out of a house within ninety seconds!

So if there’s such little time, is it not crucial that the home security cameras are quick? When there’s a wireless security system, the chances of bringing the cops to the house are better. Hence, before the burglars escape, they’re caught.

Apart from that, home security alarms also offer better and more features. For example, one can control these devices from any place using mobile apps.

While wired security systems require physical presence and control panel access, it’s different from wireless. In addition, the latter also allows certain smart home automation features.


In a nutshell, wireless security systems, including wire-free home security cameras, are reliable. Besides, all these smart systems’ features aren’t present in wired security devices.

From streamlined installation to remote access, they are super easy to use. According to experts, going wireless is a wise choice for most people. So, ready to keep the house secure?
