Support options explained
Give the right people access.
Keep the administration manageable.
Residents move. Staff change. Visitors arrive. A well-planned system helps you keep access permissions up to date, with convenient ways in for the people who need them.
Answer the gate on your phone
An Accentronix cellular intercom calls the resident’s phone. Speak to a visitor and operate the connected entrance from the call, wherever you have suitable mobile coverage.
Invite visitors with a PIN
Issue visitor codes through the app for use at a compatible keypad. Available options include controlled entry and exit, with permissions configured for the property.
Remove a lost remote’s access
Link supported remotes to individual users. An administrator can withdraw a lost remote or a former resident’s access through the cloud management platform.
Set access days and times
Give staff, contractors or service providers access during approved periods. Match permissions to their role and the entrances they need to use.
Review access activity
Use available event logs and reports to help investigate access queries and manage the site. The detail recorded depends on the equipment and access method.
Connect the entrances that matter
Plan vehicle gates, pedestrian entrances and selected doors as part of one access strategy, using the appropriate controllers, readers and permissions.
Features depend on the selected hardware, receivers, connectivity, subscription and configuration. We confirm the combination required for your site before installation.
One platform. Different access needs.
We start with how your property works, then specify the equipment and access rules to suit it.

The right equipment.
Working together.
Stemar specifies and supplies the system as part of your installation. Tell us what you want to achieve; we will identify the suitable models and accessories.
Intercom Infinity
Cellular audio intercoms that call residents’ phones, with keypad, directory and two-button options. Combine visitor calling with suitable access-control features for your entrance.
Cellswitch controllers
Nano, Nano Plus and Infinity controllers add connected control to suitable equipment. User capacity, inputs and accessory support guide the choice for a home or a larger site.
Cloud-linked remotes
Assign compatible remotes to users and manage their permissions online. Supported NICE / ET and NOVA integrations require the correct built-in or additional receiver.
Keypads & smart tags
Use suitable wired or wireless keypads for PIN access, and smart tag readers for convenient everyday entry. Reader selection and controller compatibility are checked together.
Facial recognition
Connect compatible Hikvision facial terminals through the Accentronix Easy-Connect Cloud Hub. Plan enrolment, access permissions and a suitable alternative access method for the site.
Visitor & vehicle access
Licence disc scanning supports a managed visitor-record process. UHF windscreen tags provide a separate option for hands-free vehicle access, with suitable readers and positioning.
| Product family | Published user capacity | Typical role |
|---|---|---|
| Cellswitch Nano | Up to 10 users | Compact control for a small user group |
| Cellswitch Nano Plus | Up to 10,000 users | Compact control for larger access lists |
| Cellswitch Infinity | Up to 10,000 users | Control with additional input and connectivity options |
| Intercom Infinity | Up to 10,000 users | Visitor audio calls combined with entrance control |
Capacities are manufacturer hardware specifications. Subscription categories, reader limits, wiring, remote compatibility and the current model revision are confirmed separately in your quotation.
From invitation
to the entrance.
A practical visitor procedure gives residents convenience and helps administrators keep access organised.
01 · Invite the visitor
An authorised resident creates a visitor invitation in the Accentronix app using the permissions available at the property.
02 · Share the access PIN
The visitor receives the relevant PIN and instructions. Access can be configured for the permitted entry, exit or visit period.
03 · Use the configured entrance
The visitor enters the PIN at a compatible keypad. Available logs and notifications help the resident and administrator follow the visit.
Manufacturer’s illustrative system layout. Your installation may use a smaller selection of equipment. Compatible electric-fence integration can be assessed separately.
Start with the entrance
you already have.
An upgrade may be possible using suitable existing gate equipment. We assess what can be retained and what needs to change before recommending a system.
Gate motors, locks and entrances
We check control inputs, entrance operation, pedestrian access, safety equipment and the way people enter and leave.
Existing remotes and readers
We identify supported equipment and any receiver or reader changes needed. Compatibility is confirmed for the actual models on site.
Power, cabling and connectivity
We consider signal coverage, power requirements and suitable backup arrangements, together with the location of each device.
Bring these details to the first discussion.
A few practical details help us understand the project and prepare for a useful assessment.
- The property name, suburb and contact person
- Approximate number of units, residents or users
- Vehicle gates, pedestrian gates and doors to control
- Existing intercom, motor, remote and reader models
- Visitor procedures and any guardhouse requirements
- Who will manage the system after handover
- Any access problems you want the upgrade to solve

Before you
upgrade.
We will confirm the details for your property when preparing the quotation.
It may be possible to connect a suitable controller to your existing entrance equipment. We check the motor or lock’s control inputs, power supply, safety arrangements and the access features you need before confirming compatibility.
That depends on the remote models and receivers currently installed. Accentronix supports suitable NICE / ET and NOVA integrations, with additional compatible receivers required for some combinations. We identify what can be retained as part of the assessment.
The Intercom Infinity models described here provide cellular audio calling. Facial-recognition terminals are a separate access option. If you need visitor video, tell us so we can assess a suitable solution and explain the differences.
Yes. Applicable Accentronix subscriptions and service charges depend on the site type and selected equipment and services. First-year inclusions and renewal terms are confirmed in the quotation. Calling or messaging charges may also apply.
Operation depends on the hardware, power supply and access method. Compatible devices offer nearby Bluetooth access, while some locally stored credentials may continue operating in certain conditions. These features do not cover every outage or expired-subscription situation. We discuss suitable backup power and alternative access arrangements for the site.
Suitable system configurations support visitor PINs and access schedules. We agree how codes will be issued, which entrances they operate, and the permissions needed for residents, staff and service providers.
We agree the authorised administrators and handover arrangements with you. Training covers the routine tasks in your installation. Any ongoing user administration or support provided by Stemar is agreed and quoted separately.
Compatible facial terminals and licence scanners provide additional access and record-keeping options. Before including them, we discuss enrolment, administrator permissions, the information required and suitable access to records. The property’s responsible administrator should establish its privacy and retention procedures.
Selected Cellswitch devices support integration with compatible energizers through the appropriate interface. Available monitoring and control depend on the energizer model and installation. Tell us your energizer make and model if this is part of your requirements.
Cost depends on the equipment, number of entrances, existing infrastructure and configuration. Send your suburb and a brief description using the enquiry options below. We confirm service-area coverage and any assessment charge before arranging a visit.
