Wireless security makes its mark

Wireless connectivity has become a standard for many security technologies, especially in the alarm and intrusion market. Alarms have always had a wireless component since the first monitoring control room was launched, but internally, homes and companies used to (and still do) install cables to connect various sensors and devices to the control panel.

Today, homes and businesses can do everything without a single cable as wireless technologies connect even cameras to central control points. Of course, the wireless technology used determines how many devices can be connected and how reliable the communications are – especially in the age of signal-jamming technologies.

SMART Security Solutions asked Ajax Systems and PIMA for some insights into its solutions and the utility of wireless for reliable alarm and intrusion operations.

According to Ajax, wireless alarms offer several advantages over wired options, including easier installation, flexibility in device placement, and scalability. It eliminates the need for complex wiring, making the installation process faster and less intrusive, especially in existing structures. Wireless systems are also more adaptable to changing needs, allowing for the easy addition of new devices.

PIMA states that the advantages of wireless alarm systems include easy installation, simplicity, and not requiring wiring throughout the house, especially if the house was not built with preparation for alarm system wiring.

Modern wireless systems are designed to be as reliable as wired systems. Ajax uses advanced wireless technologies that ensure strong, stable connections and can alert users to any interference. The company is known for its Jeweller wireless product line. However, since 2021, it has also offered a wired line of security devices called Fibra.

On the other hand, PIMA adds that wired alarm systems are generally more reliable than wireless systems because they are not vulnerable to wireless signal jamming, are not affected by the site’s construction (walls, metallic doors, etc.), and do not require periodic battery replacements. PIMA offers wired hybrid and wireless systems.

Secure wireless connectivity

When it comes to the security of wireless systems, preventing jamming and other potential interference, Ajax states that wireless communications can be secure and resistant to disruption with the right technologies and protocols. Its proprietary Jeweller radio technology guarantees uninterrupted interaction between the hub and security system devices. Jeweller offers a range of up to 2000 metres and provides high energy efficiency. Ajax detector batteries last 5-7 years.

Its two-way radio communication features an algorithm to confirm the delivery of events and automatic frequency hopping in case of interference. Alarms are transmitted in less than 0,15 seconds. Moreover, block cipher encryption of data, frequency hopping, and device authentication during each contact prevent the forgery of equipment and signals.

It is not impossible to jam Jeweller; however, the operation can only be interrupted by jamming all wireless signals near the protected property. Even in this scenario, the company says the system would not be compromised as Ajax will notify both the alarm response company and users about the issue.

Ajax hubs (central units) provide various communication channels, including Ethernet, Wi-Fi, and two 2G/3G/4G SIM card slots to connect with the outside world. These channels work in parallel and back each other up in case of an emergency.

PIMA also notes that wireless communication is susceptible to jamming. However, its control panel for a wireless alarm system monitors the wireless peripherals and alerts when communication with them is lost.

The Ajax offering

The Ajax product line comprises over 130 wireless and wired security and automation devices. The company offers intrusion protection, video surveillance, fire detection, water leak prevention, and home automation solutions. It connects to all popular central monitoring stations via Contact ID and SIA standards. The company also provides access to the Enterprise API to large security and service provider companies already serving, or planning to serve, thousands of Ajax security systems.

PIMA’s wireless communication utilises the unlicensed 433/868 MHz range and a proprietary protocol for transmitting events from various peripherals. Its Force series is a hybrid system supporting wired and wireless peripherals, and Vision is an all-in-one wireless system.

Its alarm systems come in different models, some of which can support up to 144 zones, including 32 wireless zones. Each zone can be customised with features like delayed activation or 24-hour monitoring, and can be categorised as burglary, panic, and more as needed.

The PIMA systems also support up to 144 users, each with their own permissions. They can connect to the Internet using an Ethernet port and cellular modem and send reports to Central Monitoring stations via IP and PSTN (telephone line). Additionally, the alarm systems can send reports to the user’s smartphone using the PIMALink 3 app, allowing remote control of the alarm system, including arming, disarming, and more.

Recently, Ajax unveiled a new line of CCTV products with a unique approach to privacy. The company introduced TurretCam, BulletCam, and DomeCam Mini cameras as part of the Baseline product line. Harnessing the power of the proprietary JetSparrow technology, these devices blend high-definition surveillance with privacy safeguards. Designed for versatility, they are suitable for both indoor and outdoor environments and boast an IP65 rating. Passwordless authentication ensures a seamless and secure setup.

The company has also released an NVR, a network video recorder that captures video streams from Ajax and third-party cameras onto a hard drive.
