The hub can operate with a 2G network connection, sending all alarms, events and Photo in Case of Alarm (depends on the hub model) to the users and the security company’s Central Monitoring Station.
The minimum connection speed required for the hub operation is 0.5 kbps.
All Ajax detectors and devices can be connected to a hub except another Ajax hubs and ocBridge Plus and uartBridge integration modules.
Please note that Hub 2 (2G) and Hub 2 (4G) are not compatible with wired Fibra products.
Correct operation of a hub is guaranteed at a temperature ranging from -10°C to +40°C and humidity up to 75%.
Mounting a hub inside rooms with a different temperature mode can lead to loss of communication with Ajax devices, and in the worst case — to failure of the device. Note, that the battery life of the hub can be significantly reduced at low temperatures.
Yes, the Ajax security system can operate when only one of the communication channels is used.
Nevertheless, we recommend connecting all communication channels as one channel may stop functioning. For example, if you run out of balance on your account or due to a malfunction of the operator’s equipment.
Hub 2 (2G) uses only 2G technology to transfer data via the mobile internet connection.
Hub 2 (4G) supports 3G and 4G (LTE) networks.
Hub 2 (2G) uses 3 communication channels for transmission of alarms to users and the monitoring station of a security organization: Ethernet (main communication channel) and two 2G SIM cards (backup channel). If one of the channels is temporarily unavailable, the system switches to the other one automatically and without delay.
You can install a SIM card of any operator supporting 2G internet into Hub 2 (2G).
Prior to installing the SIM card into the hub, disable the PIN code request in the settings menu (in order to do this, you need to insert the card into a phone). Furthermore, your mobile account must have a positive balance or bonus megabytes of traffic.
We recommend inserting two SIM cards into Hub 2 (2G) at the same time as one SIM card may stop functioning if you run out of balance or if a failure occurs on the provider’s side.
It is possible under the following conditions:
It is also recommended to attach the hub to the table with screws. Otherwise, if you try to demount the device, the tamper will not be triggered and you will not receive a notification.
The communication range between the hub and the device is limited by the radio signal range of the device (indicated in the specifications of the device page on the website and in the User Manual). The maximum communication range with Ajax devices is 2000 meters without obstacles.
Up to 9 security groups.
Up to 25 cameras or DVRs.
Up to 50 security system users (regular and PRO).
Up to 100 detectors or Ajax devices.
No more than 10 sirens HomeSiren or StreetSiren can be connected to the hub!
Hub 2 (2G) Jeweller represents an intelligent security system control panel with alarm photo verification.
