 Trustindex verifies that the original source of the review is Google. Sipko did an exceptional job with our new home security system and we're very happy with it. We dealt with the business owner, Serhii. He is intelligent, practical, organised, well presented and genuinely cares about the standard of product and delivery. After Serhii and his team had finished the install, Serhii spent all the time we needed in order to train us and educate us about the new systems and how best to use them. He listened very carefully when I outlined our requirements and delivered a solution which matches our needs exactly. Would absolutely recommend Sipko to anyone out there looking to upgrade their home security.

He showed us how to use the devices with care and enthusiasm for the products that were installed. The system is working flawlessly after a few tweaks for a lived experience with a big dog :)

Super easy to deal with and great communication to organise. I upgraded our alarm system, added a CCTV system and upgraded our door access intercom. Serhii and his team were super knowledgeable and did a great installation on site. Very happy with the end result and would highly recommend his services. Thanks Serhii

FAQ

What is the AJAX ReX 2 Range Extender and why do I need it?
The AJAX ReX 2 is a wireless range extender that boosts the communication distance between the AJAX Hub and devices such as motion detectors, door contacts, and sirens. It’s essential for large Melbourne homes, warehouses, or multi-storey properties where standard signal range may be limited.

Can I use multiple ReX 2 units in one system?
Yes – up to five ReX 2 range extenders can be connected to compatible Ajax hubs, depending on the hub model. This makes it possible to secure very large Melbourne properties, commercial sites, or multi-building setups with full system reliability. The number of devices operating through each ReX 2 depends on the connected hub and system configuration.

Can I add more extenders later?
We can design multi-extender layouts for large or complex sites. Ask us for a site plan.

Where is the best place to install the AJAX ReX 2 in properties?
Ideally, the ReX 2 should be placed midway between the AJAX Hub and the devices it needs to connect.
