How to Choose the Right Detection and Monitoring System

How to Choose the Right Detection and Monitoring SystemTerrAlert Team · 2026-09-09Choosing a detection and monitoring system is easier when you know which questions actually separate a reliable product from an impressive-sounding one. This is a practical checklist, organized around the areas that matter most in practice.What to look forCoverage and resolution. What imagery does it actually use, and at what resolution? A system built on open, well-documented satellite programmes (like Sentinel-2) has a track record you can independently verify; ask specifically what data source underlies the product, not just "satellite imagery."Realistic speed claims. As covered in How Fast Are Satellite Alerts, Really?, ask for a typical, real-world time from change to alert, not a theoretical minimum. A vendor who gives you a specific, slightly unflattering number is more trustworthy than one who says "real-time" without qualification.Questions to ask about accuracyDo not ask only "how accurate is it." Ask:

What was that number measured against, a public benchmark dataset, or your specific type of terrain and change?

Does the system corroborate findings against independent sources, or rely on a single model's opinion? (See Understanding False Alarms.)

Can you configure the sensitivity/confidence threshold yourself, or is it fixed?

A vendor who cannot answer the first question specifically, or who quotes one number without qualification, is giving you less information than it sounds like.Costs to understand before signing

Cost type

What to ask

Base subscription

What is included, and what triggers an overage?

Per-image or per-scan fees

Does the price change with how much you monitor, or is it flat?

Data/imagery licensing

Is the underlying satellite data open (like Sentinel-2) or a paid commercial feed passed through to you?

Integration/API access

Is programmatic access included, or a separate add-on?

Flat, predictable pricing without hidden per-scene charges is easier to budget against than a system where cost scales unpredictably with usage.Support and securityAsk what happens when something goes wrong: what is the actual support response time by plan tier, is there a documented security posture (encryption, access controls, breach disclosure process), and does the vendor support standard integrations (webhooks, a documented REST API) or lock you into their own dashboard only.Integration fitA monitoring system that cannot get its findings into the tools your team already uses, email, Slack, Teams, or your own systems via API, creates an extra manual step that erodes exactly the speed advantage the system exists to provide. Ask specifically about webhook support and API access before assuming it exists.What a monitoring system is not a replacement forNo evaluation of a monitoring tool is complete without also being clear about what it cannot do. See Satellite Detection vs. Manual Site Visits for where a person on the ground still beats any remote system, regardless of which vendor you choose.A short evaluation checklist

What satellite data source, resolution, and revisit schedule does it actually use?

What is the realistic, typical time from a real change to an alert reaching you?

Does it corroborate findings against independent sources, and can you configure sensitivity?

Is pricing flat and predictable, or does it scale with usage in ways you cannot easily forecast?

What is the support response time by plan, and is there a documented security policy?

Does it integrate with the tools your team already uses, email, chat, API?

Key takeaways

Ask what data source and resolution underlie a system, not just "does it use satellites."

A single accuracy percentage is a weak signal; ask about corroboration and configurability instead.

Flat, predictable pricing and real integration support (API, webhooks) matter as much as detection quality for whether a system actually gets used.

FAQIs the cheapest option usually the worst? Not necessarily, but a very low price with unclear data sourcing, no corroboration, and no support commitment is a common pattern worth investigating before committing.How much does integration really matter? A lot, in practice. A system whose findings never reach the tools your team actually watches tends to get checked less and less over time.References
