Ajax vs Satel: Which System to Choose?
The two most specified systems in European premium security installations — the practical choice depends on project type, not brand preference.
The fundamental difference
Ajax Systems
Wireless-first system from Ukraine. Designed for retrofit, no-drill installations and premium residential. Beautiful app, strong encryption, modern UX.
- ✓ No cabling required (Jeweller)
- ✓ Excellent iOS/Android app
- ✓ Fast installation
- ✓ Cloud monitoring included
- ✗ Higher cost per zone
- ✗ Limited 3rd party integrations
Satel Integra
Wired alarm panel from Poland. Industry standard for commercial and large residential. Mature ecosystem, deep third-party integrations, KNX module available.
- ✓ Up to 256 zones (Integra 256)
- ✓ Deep KNX integration (INT-KNX)
- ✓ Mature monitoring protocols
- ✓ Lower cost at scale
- ✗ Requires cable installation
- ✗ Older UI / app experience
Side-by-side comparison
| Feature | Ajax | Satel Integra |
|---|---|---|
| Communication | Wireless (Jeweller) + wired (Fibra) | Wired (bus) + wireless (Abax 2) |
| Max zones | 200 (Hub 2 Plus) | 256 (Integra 256) |
| Max users | 200 | 256 + codes |
| Partitioning | 50 partitions | 32 partitions |
| Mobile app | Excellent (native iOS/Android) | Adequate (INTEGRA CONTROL) |
| KNX integration | Via webhook/bridge (unofficial) | Native INT-KNX module |
| Monitoring protocol | Ajax Cloud / SurGard | Contact ID, SIA, SurGard |
| Typical project size | Apartments, villas, small offices | Commercial, schools, hospitals |
| Cost per zone | Higher | Lower at scale |
| Installation time | Fast (wireless) | Slower (cabling required) |
| Retrofit suitability | Excellent | Moderate |
| Cybersecurity | AES-128, 2-way RF jamming detect | Encrypted IP, physical tamper |
Decision guide
✓ Choose Ajax when:
- →Residential project (apartment, villa) up to 50–100 zones
- →Retrofit — no cable routes possible or disruptive
- →Client wants a modern mobile app experience
- →Project timeline is tight (wireless installation is 3–5× faster)
- →Cloud monitoring via Ajax Cloud is acceptable
- →Fibra wired available where needed (basement, EMC areas)
✓ Choose Satel Integra when:
- →Commercial building with 50–256 zones
- →Deep KNX integration required (INT-KNX module provides direct bus connection)
- →Professional monitoring station requires Contact ID or SIA protocol
- →Project has cabling infrastructure already planned
- →Long-term reliability critical (schools, hospitals, government)
- →EN 50131-3 Grade 3 certification required
Can you combine Ajax and Satel?
Yes — and it's occasionally the right answer for complex projects. A common hybrid: Satel Integra as the main alarm panel (monitoring, zone management, EN 50131 certification), with Ajax used purely for wireless sensor expansion in difficult-to-cable areas. Ajax Hub outputs (WallSwitch) can connect to Satel zone inputs. However, this adds cost and programming complexity — only worth it when each system's strengths are genuinely needed in the same project.
