About this skill
What It Solves
In weak-current intelligent building, IT/network, and telecom projects, equipment selection often stalls on inconsistent parameters, unsupported model recommendations, missed compatibility checks, and rough budgeting. Device Selection Advisor targets scenarios such as structured cabling, surveillance, access control, intercom, public address, BAS, parking, switching, security, storage, optical transport, and wireless base stations. It grounds recommendations in knowledge-base retrieval results and standard references rather than model memory.
How It Works
The skill connects to the Weak-Current Intelligent AI knowledge base (IMA ID: 7383010441698671) through mcp__ima-mcp, then runs multi-keyword search, deduplication, cross-validation, and prioritizes standard-library and technical content. Core capabilities include:
- Requirement-driven recommendations: outputs basic / standard / premium tiers based on project scope, scale, feature level, and budget.
- Parameter comparison: compares model, interface, performance, power, protection rating, and price range in structured tables.
- Compatibility checks: verifies
ONVIF,BACnet,POE, port count, uplink bandwidth, VLAN, rack space, and software channel capacity. - Cost estimation: breaks down equipment, materials, installation, and commissioning costs, with optimization notes.
- Brand comparison: provides neutral comparison across value, service coverage, ecosystem compatibility, and use case.
A typical workflow is: collect project context and scale, query the knowledge base, shortlist candidate models, then output parameter tables, compatibility checks, budget, and standard references.
Boundaries and Notes
It is scoped to weak-current intelligent buildings, IT/network, and telecom equipment selection. If a parameter is not indexed, it advises checking vendor manuals or suppliers instead of inventing models. Mixed-domain requests are split into modules, and vague requirements are clarified around scenario, tier, and budget. Brand recommendations remain neutral and use-case oriented.
Use Cases
- Before an office weak-current retrofit, compare CAT6 cable, PoE switch, and core switch specs to produce three-tier selection options.
- During surveillance procurement, verify camera count, NVR channels, PoE power budget, and storage capacity for 30-day retention.
- In a BAS design phase, shortlist DDC controllers, sensors, and actuators, then output BACnet compatibility and budget estimates.
- Before base-station build-out, compare BBU, RRU, and antenna options against power, interface, and coverage requirements.
Best For
- Building integration engineer planning weak-current retrofits who needs standard-based comparison of cabling, switches, and PoE budgets.
- Security surveillance project manager preparing a bid proposal who needs three-tier camera/NVR configurations, storage sizing, and budget.
- BAS or building controls engineer selecting DDCs, sensors, and actuators who needs BACnet compatibility checks.
- Telecom design engineer comparing BBU, RRU, antenna, and power/interface options for base-station projects.
