Ajax Security System — A Detailed Guide to Selection, Implementation, and Operation
Briefly: an in-depth and practical article about the Ajax system: technical details, kit selection for apartments, cottages, and stores, installation and integration instructions, and tips for connecting to the IMPERIA monitoring station.
1. What Ajax Is and What the System Consists Of
Ajax is a flexible security platform built from a control center (Hub), wireless and wired detectors, sirens, panic buttons, integration modules, and a mobile app. The system is focused on fast response, resistance to tampering, and ease of management.
Key Elements
- Hub (central controller) — the brain of the system, managing the entire set of devices, supporting Ethernet and backup communication (SIM/LTE).
- Opening detectors — contact sensors for doors and windows.
- Motion detectors — PIR/microwave sensors with algorithms to reduce false alarms.
- Smoke/CO/leak detectors — for fire and engineering safety.
- Sirens (indoor/outdoor) — sound and light signaling.
- Panic buttons — portable and stationary.
- Integration modules — for smart home control, relays, video cameras, and monitoring station connection.
2. Technical Specifications — What to Look For
Below are the important parameters that affect the reliability and suitability of the system for your property.
| Parameter |
What Matters |
| Radio communication range |
Indicated in the factory documentation (e.g., up to 2000 m in open space), in practice it depends on wall thickness and materials. For large sites, plan repeaters or additional hubs. |
| Max number of devices |
Different Hub models support from ~50 to 200 devices — consider future expansion. |
| Communication channels |
Ethernet, Wi-Fi (rarely), LTE/SIM — a backup channel is critical for resilience if the internet goes down. |
| Response time |
From sensor triggering to notification — fractions of a second to ~1 second with normal connection. |
| Power and backup |
Battery in the Hub + autonomous batteries in detectors. Check the runtime under load. |
| Encryption and authentication |
Availability of a reliable communication protocol with encryption and device authentication checks. |
Battery life: 2–7 years
Typical notification delay: <1 s
Device connections: from 50 to 200+

4. Installation Guide and Implementation Stages
Proper installation ensures reliability. Below are the standard stages of implementing the Ajax system.
- Pre-project inspection: engineer surveys the property, measures signal levels, identifies vulnerable spots, and prepares a placement plan.
- Design: layouts of detectors, cable routing (if wired elements are used), selection of Siren and Hub installation points.
- Equipment preparation: firmware updates, device pairing with the Hub in service mode, checking module compatibility.
- Installation: mounting detectors, laying cables (if required), installing sirens and external antennas/repeaters.
- Fine-tuning: adjusting zones, sensitivity, automation scenarios, testing all alarm scenarios.
- Integration with monitoring station: configuring signals in the format accepted by your security company, test alarms, and response procedure training.
- User training: training users on working with the app and actions during an alarm.
Post-Installation Checklist
- Connection of each detector to the Hub checked (RSSI/signal levels).
- False and real alarms simulated, owner and monitoring station notifications verified.
- Operation checked during internet and power outages.
- Owner and responsible persons’ contacts registered for alarm notifications.
5. Integration: Video Surveillance, Smart Home, Monitoring Station
The Ajax system easily integrates with DVRs, cloud video surveillance, and automation systems (via modules and API). Example scenarios:
- When a motion detector triggers — cameras start recording and a fragment is sent to the cloud.
- During an alarm — lights turn on and outdoor cameras record the intruder’s path.
- Heating and ventilation shut down when CO/gas is detected.
Connection to the IMPERIA Monitoring Station
To connect the system to a professional monitoring station you need:
- Compatible alarm transmission format (SIA/Contact ID protocols or proprietary API solutions).
- Configured transmission channel (IP, LTE) and redundancy.
- Test alarms and verification of response team procedures.
6. Expert Tips and Best Practices
- Duplicate communication channels. Ethernet + LTE/SIM is the basic set for guaranteed signal delivery.
- Use multi-zone architecture. Separate security into day/night scenarios and zones with different priorities.
- Minimize false alarms. Adjust sensor sensitivity and avoid direct light/heating sources in detection zones.
- Backup runtime. Check backup battery capacity and Hub runtime in the documentation.
- Regular testing. Every 3–6 months perform a full test simulating different situations.
- Updates and logging. Keep firmware up to date and save alarm logs for incident analysis.
7. Technical FAQ — Quick Answers
What if a detector has poor signal reception?
Check RSSI/signal level in the app, move the Hub or install a repeater. Make sure there are no large metal obstacles between the Hub and detector.
How does the system behave during a power outage?
The Hub runs on its built-in battery; depending on the model and load, runtime can be from several hours to a day — check the specifications.
Can Ajax be integrated with a third-party camera?
Yes — via integration modules or API. A common scenario: during an alarm the camera starts recording and saves a clip to the cloud/NVR.
8. Scheduled Maintenance and What to Check
- Battery status in the app — every 3–6 months.
- Signal level and RSSI check — annually and after reconstructions/repairs.
- Monitoring station testing and response scenarios — every 6–12 months.
- Cleaning outdoor detectors and checking outdoor siren sealing — before rainy/cold seasons.
9. Examples of Non-Standard Deployments
Ajax is used not only in residential properties: security for construction sites, warehouses, mobile retail points, temporary pavilions. In such cases, it is important to:
- Use autonomous power and LTE connection.
- Apply vibration and shock protection (acoustic and vibration detectors).
- Restrict access through multi-user roles and permissions.
10. Cost of Ownership and Commercial Offers
The system cost consists of:
- equipment (Hub, detectors, sirens),
- installation and commissioning works,
- monthly monitoring and subscription to the monitoring station,
- maintenance and component replacement.
Note: exact prices and packages should be clarified with IMPERIA specialists — they will prepare a commercial offer tailored to your property and budget.
