Types of alarm panels
Alarm panels control two states of one or more loops: "normal", corresponding to the standby and armed mode, and "alarm". The alarm mode is activated when there is an attempt to damage the devices of the security system, when the territory has entered or when other pathogens from the connected sensors are detected.
The disadvantages of such reception and control panels are apparent; it is the impossibility of a precise location of the operation and the low information content.
There are no such shortcomings in the addressing of signalling devices to protect the territory. They make it possible to connect about 100 alarm sensors to a two-wire line, depending on the type of control panel.
The digital method of data transmission increases the informational content of the alarm loop, which contributes to the reliability of the security system. Since the implementation of the address principle requires the use of microprocessor control, these control panels can create different types of security zones, organize interaction with other types of executive devices, and configure them flexibly.
It is important to note that the compatibility of the security sensors with the alarm panel must be ensured when using addressable systems.
Another type of control panel is wireless. Devices of this type are radio frequency receivers with various monitoring functions. Professional radio channel systems include a set of devices with a different set of options. For example, an alarm control and management center can work with wired loops and at the same time support the interface connection of a radio receiver.
In this case, the central office only receives data and transmits it for further processing. This principle of operation allows you to create security systems of various capacities and complexity, suitable for installation in private houses, summer cottages or apartments.
Setting up and mounting the reception panel
The installation of the safety system devices is carried out according to the rules that provide:
- Even minimal risk of unauthorized access to the alarm and controls and switching devices.
- Efficiency and reliability of the security system.
- Fire and electrical safety.
To comply with the standards, the control panel must be installed on non-combustible surfaces and make connections to the electrical network with wires of appropriate cross-section with high-quality insulation. If the design of the control panel requires grounding, this should not be overlooked.
Attention should be paid to the assembly and installation instructions attached to any device, and often have individual characteristics for a particular type of equipment.
To protect devices during unattended periods, they must be mounted in spaces with limited access to unauthorized persons. Most burglar alarm devices are equipped with tamper-evident sensors so that the alarm control device itself can be protected at all times.
Smart control panel Ajax Hub 2 (2G or 4G) for anti-theft alarms
The Ajax Hub 2 alarm center is a device for organizing a remote or autonomous alarm based on wireless detectors and other devices using 2 GSM SIM cards and an Ethernet network. The alarm control panel coordinates the operation of alarm system devices, immediately signals alarms and provides automatic intelligent control of security processes.
The security system Ajax with the connected central Ajax Hub 2 (2G or 4G) supports the maximum number of:
- Work scenarios – 32.
- Security groups for device control – 9.
- Possible connected devices - 100.
- Signal repeaters Ajax ReX - 5.
- There are 25 video cameras in the system.
- Rooms under protection – 50.
- The number of possible users is 50.
The body of the control panel is made of black or white plastic, which makes it possible to integrate the device into any interior. Power is provided by an ac 110-240V internal power supply or a backup Li-Ion battery with a capacity of 2 Ah.
Features of the Ajax Hub 2 (2G or 4G) alarm panel
The sensors of the security system detect the appearance of human movements, smoke, water, gas leaks, opening windows or doors. Third-party cameras are used for video surveillance. Alarm notifications are sent to users via push notifications, SMS or phone calls, and it is also possible to connect an alarm to the control panel of a security organization.
Redundant control panel communication channels
The GSM Hub 2 module supports two SIM cards. The use of cards from two different operators allows the central to communicate even if one of the networks is lost – the second SIM card is automatically activated.
Users of the Hub 2 traffic control panel have access to an uninterrupted internet connection, thanks to working with different internet providers; cellular to connect to one, Ethernet to the other.
Even if the service provider goes down and the Ethernet connection is lost, Hub 2 will connect to the 2G or 4G network to access the Internet. If a carrier's coverage is lost, the hub will immediately switch to the second SIM card.
Unlike video surveillance, Ajax Hub 2 (2G or 4G) can transmit photo confirmations even if the connection speed is only 0.5 Kbps on a 2G network and provides a series of images to system users.
Secure communication with video cameras, sensors, signal repeaters
The alarm control panel Ajax Hub 2 receives information from sensors in encrypted form and works on OS Malevich with protection against viruses and cyberattacks. The Hub continuously checks the status of the detector every 12 to 300 seconds using two-way communication. The verification frequency is individually configurable.
Ajax Hub 2 switches signaling to other frequencies if signal interference is detected. Hub is fully protected against viruses at the software level.
An Internet connection allows Ajax Hub 2 to communicate 24 hours a day via an encrypted channel with the Ajax Cloud server. This principle of operation guarantees fast receipt of updates, secure access to the device, storage of its settings.
Photoverification of alarms
A distinctive feature ofAjax Hub 2 control panels and Hub Plus is the expansion of the possibilities of transmitting visual information and connecting motion sensors Ajax MotionCam with an integrated camera thanks to the Wings radio protocol.
MotionCam provides the system user with an animated series of 1 to 5 photos, which he will receive in less than 9 seconds after detecting and triggering the sensor. Thanks to the Wings radio protocol, photoverification is guaranteed even with an unstable signal and communication interruptions - the built-in algorithms double-check and reload packets, and the reliability of the communication channel is increased through the use of a dedicated antenna on the control panel.
When an alarm is detected, the alarm sensor can take up to three images at 640×480 or up to 5 images at 320×240, depending on the settings. The Ajax application reproduces the photo in animation, providing dynamic information for a correct assessment of the situation.
The infrared lighting of the camera provides good visibility even in the dark and is only activated in the event of an alarm. Snapshots can be saved in one go as a series of PHOTOS or MP4 videos or individually.
Installation and configuration of the Ajax Hub 2 (2G or 4G)
Ajax Hub 2 is mounted on the SmartBracket stand and the built-in power supply allows you to connect the device directly to the mains without installing an outlet.
The alarm sensors are connected via a free phone app after reading the QR code on the device. The detectors are installed in a line-of-sight area up to 2 km or on several floors of the building. Ajax sensors work without charging for up to 7 years, taking pings every minute to check device performance.
