Simple integration for maximum security
Now the market has a system that seamlessly integrates with your security devices so you can have ultimate control of your environment. JanusC4 has been developed to meet the growing demands of today’s world, designed to enhance your existing systems and unite them in one, simple dashboard.
CCTV
Integrated CCTV associates access events and alarms with recorded video footage to see what events occurred leading up to an incident. Automated actions allow live feeds to be brought up in the event of an incident or alarm.
Microsoft Active Directory
A single source of truth for the AC system allowing the synchronisation of access permissions, credentials, and employee information according to a person’s position within a business. Updated in real-time therefore removing the need to update the security system manually ensuring that employees rights are updated, edited, or removed as part of the HR process.
Alarm Systems
Automated arming and disarming of a buildings intruder alarm system, ensuring the alarm is only armed when the building is empty, avoiding unnecessary and costly false alarm triggers. Arm and disarm zoned alarms to provide added assurance a multi-site business remains secure and covered by insurance requirements.
Locks
Stored access rights and decisions made at the ‘edge’ ensuring that access is only provided to those that are authorised, even in the event communications are down. Restoration of connection to the main AC server uploads ‘offline’ events to ensure the audit log remains up to date.
Lifts
Individual access rights to certain floors ensure only the relevant people can access the appropriate location on a multi-levelled building by lighting only the relevant buttons within a lift cart. Tailgaters are then caught when attempting to access doors on floor levels they are unauthorised to use, allowing the system to raise alarms and notification to the building security team to advise on the unauthorised access whilst the system inhibits the users credential preventing any further access around the site.

One of the greatest benefits of JanusC4 is the powerful and dynamic integrations that can be achieved software to software with leading products with providers such as Hikvision, Dahua and Avigilon. Wireless locks can be added using Aperio, whilst Galaxy and Texecom work seamlessly with JanusC4 to ensure intruder alarms are set when the last person leaves a building. Active Directory can be linked with our own software to software integration, providing a single source of truth that updates in real-time.

JanusC4 eliminates the risk of human error by introducing advanced levels of automation to your security routines. Whether that’s enabling alarms at night with a last leaving swipe, turning on carpark lights at dusk, or ensuring lifts can only be accessed by the appropriate staff, taking them only to the floors they have permission to visit.
Our in-house team of software developers are continuously striving to improve and enhance the features that JanusC4 provides. When you install JanusC4, you are getting not just the most security-rich technology of today – but of tomorrow too.

JanusC4 Hardware
Why is our hardware recommended by partners?
JanusC4 has limitless scalability. Whether you plan to grow your team or you will require additional space in the future, it’s easy to add control to new doors and zones, so your security will grow with you.
Modular blades are an innovative and adaptable approach to Access Control, allowing you to scale your security as needed. You don’t need significant investment to secure your building – by utilising blades, our multi-controller can manage up to eight doors.
Our modular blade technology allows for quick and simple expansion. From two doors up to eight on one controller, you can not only streamline your system but also reduce your costs.
The blades support OSDP, so you can enjoy the highest level of protection and the intelligent I/O module allows for a convenient and easy way to manage external equipment such as lights, air con, barriers and more.
Installation couldn’t be easier. JanusC4 Advance controllers are among the simplest to install and straightforward to use – they can be up and running in no time.
While our controllers have one of the smallest footprints on the market, that doesn’t reduce their impressive capabilities. They can store up to 250,000 credentials and provide both battery backup and offline capabilities, which means your security is maintained, no matter what.
You can select from keypad, Bluetooth, NFC or proximity readers, so your controllers suit your preferred protocols.
Our systems all comply with the highest access control communications standard – OSDP. This enhanced level of security supports high-end encryption and is more secure than other common access control communication protocols.
The intelligent I/O module allows for a convenient and easy way to manage external equipment such as lights, air con, barriers and more so you can create a smart environment for a streamlined experience.
Blades make maintenance and fault finding much quicker than with other systems. On average, our installation partners can resume your security in under an hour.
