AJAX Hub 2 Plus
Composing a complete alarm system always starts with choosing the Hub that best suits your needs.
AJAX has had a choice of 4 different versions since the end of 2020. The differences are summarized as follows:
- Hub 1: Support for 100 detectors and connected via Ethernet and possibly as a backup via 2G mobile network
- Hub 1 Plus: Support for 150 detectors and connected via Ethernet and optionally as backup via 2G or 3G mobile network
- Hub 2: Support for 100 detectors and connected via Ethernet and possibly as a backup via 2G mobile network, with as extra: Support for detectors with built-in photo camera via the Wings protocol (e.g. AJAX MotionCAM).
- Hub 2 Plus: Support for 200 detectors and connected via Ethernet and possibly as backup via 2G/3G and 4G with the additional: Support for detectors with built-in photo camera via the Wings protocol (e.g. AJAX MotionCAM).
In other words, the basic Hub 1 is sufficient if you only connect the Hub to your internet router, and do not use AJAX MotionCAM. Hub 2 can be used if you also want to connect the detectors with built-in photo camera, and Hub 2 Plus if you want to use a 4G mobile network for backup in addition to the Ethernet connection.
Many people are worried that the Hub 1 only supports 2G, but we have indicated that they will keep the 2G network on the air until at least the year 2025. And the mobile network for the Hub is only a backup connection channel to the AJAX Cloud. If your Ethernet connection, i.e. your fixed Internet connection at home, is just online, you don’t need a 2G or SIM card in the Hub at all. Even if you don’t use a SIM card and your home Internet connection is offline for a while, the alarm system will still work. You will immediately receive a message on your smartphone that the Hub is temporarily not connected to the Cloud, so you can see what the problem is. The system will simply sound the siren in case of a burglary attempt, for example, only the notification to your smartphone will be delayed.
AJAX has deliberately chosen a 2G support because this is the most powerful signal, and the AJAX system does not need a high internet speed to send messages.
What does the AJAX Hub 2 Plus do exactly
The AJAX Hub 2 Plus is the control centre of the security system and wirelessly controls all linked detectors via the Jeweller protocol. The maximum distance the Hub 2 Plus can cover with the detectors without AJAX Rex is 2000 meters. By default, the Hub checks the status of each detector every 36 seconds. For even greater security, this time can be reduced to as little as every 6 seconds. Via the AJAX application on your smartphone, you can set up everything the Hub 2 Plus should do for you.
Enormous range of 2000 metres
Through the AJAX app you can see exactly what the signal strength of each detector is.
If the distance between the detector and the AJAX Hub 2 Plus is too large, resulting in a weak Jeweller signal, place a range extender in the form of an AJAX Rex in your system, increasing the range by another 1800 meters. It won’t surprise you that a Rex isn’t often sold, thanks to the enormous distances you can cover by default. A Rex is only recommended for very large houses with hundreds of meters of land.
What does the Hub 2 and Hub 2 Plus have that the standard Hub does not have
The Wings protocol. This is a different wireless signal than the Jeweller signal that each Hub has, and also developed by AJAX itself. Thanks to the wireless Wings signal, long distance photos can be sent wirelessly from the detector to the Hub 2, and the Hub 2 is able to display this photo on your smartphone in seconds.
At the time of writing, the AJAX MotionCAM motion detector is the only detector that requires an AJAX Hub 2. All other products are compatible with the standard Hub.
More memory, more possibilities
The standard Hub is capable of executing up to 5 scenarios. An example of a scenario would be to automatically turn on the alarm system at a fixed time, or turn on the lights using an AJAX Socket. The Hub Plus has 64 scenarios. Hub 2 has 32 scenarios, and Hub 2 Plus as described on this page can perform 64 scenarios.
What can the standard Hub do
For most users, the standard Hub is sufficient, it offers more than enough possibilities for 95% of the users.
The standard AJAX Hub does not allow you to pair AJAX cameras yourself, but you can of course choose a camera of any other brand if you want to save images or watch them live.
An AJAX detector with a built-in camera can also only transmit images at the moment of detection. You cannot request a photo or video of the location if there is no detection resulting in an alarm.
So if you want to be able to view images at any time, you need to install a different brand of camera anyway. In principle, it doesn’t matter which brand of camera you choose, because all brands have their own smartphone application.
There are 4 brands that make it possible to view the images of that brand of camera in the AJAX app, but that offers little or no added value is our opinion. So just choose a camera with the right price/quality ratio for your budget. Of course we will gladly advise you what we think is the best to buy.
AJAX Hub in black and white
Because the Hub does not come into view, the colour is not so important. The Hub must be provided with power and a fixed internet cable, which comes from your router. Usually this will be positioned in the meter cupboard.
Ultimate security in communication
The AJAX Hub is permanently connected to the Internet, and is connected to the AJAX Cloud. The AJAX application on your smartphone is also constantly connected to the same AJAX Cloud, thanks to the internet on your smartphone. If, for whatever reason, the internet at home is switched off and the AJAX Hub is disconnected from the AJAX Cloud, there is no problem. Because your smartphone is still connected to the Cloud, the Cloud will notify you that the connection from the Hub to your home has been lost. It’s then up to you to see what might be going on.
If you want more certainty that the connection to the Cloud is maintained, you can easily place up to 2 SIM cards in the Hub. As soon as your Internet is offline at home, the connection switches to the SIM card. AJAX chooses to place 2 SIM cards in the Hub, because the chance that 2 mobile networks will not work at the same time is extremely small. We’ve never heard of it in Europe, and under normal circumstances that won’t happen any time soon.
Fact is that 99% of the users do not use the sim cards as a backup channel, and therefore only use the fixed internet connection at home (Ethernet). Because of this you are not stuck with monthly costs for your mobile provider sim card. The other 1% chooses to use 1 SIM card as backup channel. If you really want to get the most out of the connection options, then insert 2 sim cards.
You’re always warned
Always remember that even when the internet is offline, the system will still function. If someone wants to break in while the internet isn’t working, just start the siren. This makes the AJAX alarm system more reliable than any other brand of alarm system.
Even alarm systems that work with wired connections/connections often do not have the possibility to be notified immediately if a connection fails. Many alarm systems are connected to a fixed telephone line which sends a call to the alarm company in case of a burglary. If the telephone line has been rendered unusable, intentionally or otherwise, the burglary report will not come in.
The AJAX system has been developed to install completely independently. Watch the video below to see how to install a starter package in 5 minutes. Really anyone can do it!
