Detailed specifications and benefits
The Ajax KIT5 S is engineered to balance strong hardware with flexible communications and professional management features. Below is a closer look at the key technical specifications and the practical benefits they offer.
- Hub 2 control panel:Central brain of the system managing devices, communications and automation scenarios.
- MotionProtect S (2×):Indoor PIR detectors with pet‑immune installation options to reduce false alarms while detecting intruders.
- DoorProtect S (1×):Magnetic opening detector for doors or windows with tamper protection to detect forced entry.
- KeyPad Plus S (1×):User keypad for PIN arming/disarming, with a built‑in siren for local alerting and simple user control.
- StreetSiren DoubleDeck (1×):Powerful outdoor siren with tamper detection and adjustable decibel output for street‑level deterrence.
- HomeSiren S (1×):Indoor siren for immediate audible notification within the property.
- Comms:Ethernet (100 Mbps) plus two micro‑SIM slots supporting 2G/3G/4G depending on region — ensures multiple reporting channels and reliability.
- Auto failover:Seamless switching between Ethernet and cellular prevents loss of connectivity during outages.
- OS Malevich:Remote updates and ongoing improvements from Ajax, supporting new features and security patches.
- Scalability:Support for up to ~100 wireless devices and up to 50 users makes the Hub 2 suitable for larger homes and small commercial sites.
- Radio types:Jeweller for alarms/events and Wings for photo verification transfer; both use encrypted two‑way communication.
- Range:Open‑space radio range of roughly 1,700–2,000 m (device and region dependent) gives installers flexibility for larger properties.
- Security:Frequency hopping and encryption reduce the risk of jamming and interception.
- Photo support:Wings protocol supports photos up to 640 × 480 px from MotionCam detectors; photos can be delivered in seconds depending on comms.
- Benefit:Photo verification reduces false alarms and speeds up appropriate responses by owners or alarm receiving centres.
- Mains and backup:Hub 2 runs on 110–240 V mains with a built‑in Li‑ion backup for roughly 15–16 hours of autonomous operation (model and settings dependent).
- Form factor:Compact Hub approx. 163 × 163 × 36 mm and weighing about 351 g, suitable for discreet mounting.
- Environmental considerations:Hub rated at IP20; detectors and sirens have their own installation and weather specifications (StreetSiren is designed for outdoor use).
- Camera integration:RTSP support for up to 25 IP cameras/DVRs allows video verification and monitoring integration.
- Automation:Support for up to 32 automation scenarios enables routines (lights, locks, heaters) tied to security events.
- Installer features:PRO tools for remote management, firmware control and multi‑site configuration make the system attractive to installers and security companies.
Use cases and scenarios where the KIT5 S excels
The Ajax KIT5 S is well positioned for a range of residential and small commercial applications where reliability, scalability and professional management are important.
For detached homes or properties with multiple entry points, the KIT5 S offers robust radio range and multiple reporting channels. The included outdoor siren provides visible deterrence while interior detectors and keypad deliver everyday usability for families.
In multi‑unit buildings the Hub 2’s radio resilience and encrypted communication help mitigate interference. KeyPad access control and remote management through PRO tools make the system suitable for landlords and letting agents.
Shops, small offices and studios benefit from multi‑channel reporting and photo verification. RTSP camera integration enables a unified security feed for staff or ARC monitoring, while automation scenarios can tie lighting and access control to opening hours.
As a Superior‑series kit, the KIT5 S is aimed at authorised PRO partners and installers who require scalable device capacity, remote maintenance and professional commissioning workflows. It’s ideal for projects where a single vendor solution with strong support is preferred.
Comparisons with similar products on the market
Potential buyers will often compare Ajax to both DIY consumer systems (Ring, SimpliSafe) and professional solutions (Honeywell, DSC, Hikvision). Here’s how the KIT5 S stacks up:
- Strengths of Ajax:Stronger professional features — multi‑channel failover, encrypted radio, photo verification and higher device capacity. Better suited where an installer or ARC is involved.
- Strengths of DIY systems:Often simpler, cheaper to buy and install by owners, with heavily consumer‑focused apps and integrations.
- Verdict:Choose Ajax when you need PRO‑grade reliability and installer support; choose DIY if low initial cost and self‑installation are top priorities.
- Ajax advantages:Modern wireless architecture with extensive device ecosystem, photo verification, and cloud updates via OS Malevich. Easier and faster to install in many scenarios compared with hardwired panels.
- Traditional pro systems:Often offer similar or greater integration with legacy security infrastructure and may have different compliance profiles for certain commercial projects.
- Verdict:Ajax is highly competitive for retrofit and greenfield wireless projects where speed, scalability and modern feature sets matter. For some regulated commercial projects, wired systems with specific certifications might still be required.
