Key concepts
Networks, structures and inspections
Network : A power line or circuit, and the structures on it. A network is Transmission, Distribution or Mixed. On the Asset page, transmission networks are called lines.
Structure (or asset) : One physical asset on a network: a pole, a tower or a substation. DetectOS uses both words for the same thing. Distribution structures are usually poles; transmission structures are towers grouped into lines.
Inspection : One capture campaign over a network: the drone imagery collected on a visit, and the results of analysing it. A network builds up a history of inspections over time.
Today · Current status : The most recent completed result for every structure, combined across all inspections. It is what you see by default. You can also pick one inspection from the history to see exactly what it found.
Defects and severity
A defect is a problem found on a structure, such as a damaged component. Each defect has a severity. These are the default labels; your organization may use its own names for them.
| Severity | Color | Meaning |
|---|---|---|
| High | Red | Needs attention first. |
| Medium | Orange | Needs attention. |
| Low | Yellow | Minor issue. |
| Monitor | Green | Watch only. Doesn't lower health. |
A structure needs attention when it has at least one open High or Medium defect. That is also what Focus shows: switch to Full to see everything else.
Health and condition
Health is a score from 0 to 100 for each structure. A structure with no defects scores 100. Each defect takes away a share of the remaining score: a High defect much more than a Medium, and a Low only a little. Monitor findings don't count. Network health is the average across its analyzed structures.
Condition is the band a structure's health falls into:
| Condition | Health |
|---|---|
| Good | 100 |
| Minor | 95–99 |
| Fair | 80–94 |
| Poor | 50–79 |
| Critical | 0–49 |
| Not analyzed | No result yet |
On the map, each dot is colored by the structure's worst open defect. A structure with a single High defect shows a red dot, even though its condition may still be Fair. Grey-blue dots mean Not analyzed, which is different from "no defects".

Data confidence
Data confidence tells you how current a result is, separately from health. It starts high after an inspection and halves every two years.
| Label | Score |
|---|---|
| Fresh | 70 or more |
| Aging | 40–69 |
| Stale | Below 40 |
A network with a good health score but Stale data may be due for a new inspection.
Structure status
Each structure in an inspection moves through these steps: Pending → Uploaded → Analyzed → Approved.
Repairs
When a defect is fixed, it can be logged as a repair. Counts in DetectOS then read caught (everything ever found), repaired, and open (still to fix). Turn on Before repairs in Inspect to see the original figures as found.
