| Detection Technologies | Use a layered architecture combining RF detection with protocol analysis; add radar, remote identification, or electro-optical confirmation when the mission requires non-emitting target detection. | RF-only systems may not detect autonomous drones, frequency-hopping links, or aircraft operating without an active control signal. | Test against RF-controlled, Wi-Fi-controlled, autonomous, and low-emission flight profiles in representative environments. |
| RF Frequency Coverage | At minimum, assess coverage of commonly used sub-GHz, 2.4 GHz, and 5 GHz control or telemetry ranges. Consider regional bands above 5 GHz where legally and operationally relevant. | Consumer and professional unmanned aircraft use multiple radio technologies, and frequency allocations differ by country. | Request a frequency coverage chart, supported waveform list, scan speed, and evidence of testing across the target deployment countries. |
| Detection Range | Specify range by environment rather than accepting a single headline figure. Establish separate targets for open terrain, dense urban areas, and indoor or perimeter use. | Buildings, terrain, vegetation, antenna height, transmit power, interference, and line of sight can substantially change detection distance. | Require a site acceptance test with measured detection probability at defined distances and approach directions. |
| Detection Probability | Set a mission-specific target, such as at least 90% detection probability for the selected test set, and define the confidence level and test conditions. | A percentage without a defined target population, distance, altitude, and environment cannot be compared reliably. | Use repeatable trials with multiple aircraft types, flight paths, altitudes, weather conditions, and radio configurations. |
| False Alarm Control | Require documented nuisance-alarm performance and configurable exclusion zones, signal libraries, alert priorities, and operator confirmation workflows. | Urban public-safety environments contain Wi-Fi, cellular, Bluetooth, industrial, and broadcast signals that can create unwanted alerts. | Conduct a 24-hour or longer observation test at the intended site and record false alerts per hour by source category. |
| Identification Capability | Prefer systems that report estimated direction, signal type, protocol or waveform classification, confidence level, and time-stamped event data. | Detection alone may not provide enough information for dispatch, evidence handling, or coordinated response. | Check whether alerts can be exported in standard formats and correlated with maps, cameras, radar, or command systems. |
| Remote Identification Support | Assess support for the Remote ID requirements applicable in the target jurisdiction, including broadcast reception and data fields required by local aviation authorities. | Remote identification rules are jurisdiction-specific and may change; support should not be assumed solely from a product description. | Confirm compliance through current regulatory documentation and conduct live tests with legally compliant Remote ID transmitters. |
| Geolocation Accuracy | For systems claiming transmitter or pilot-location estimation, require a documented accuracy range, coordinate reference system, and stated conditions. | Direction finding can be affected by reflections, multipath propagation, antenna placement, and moving targets. | Compare estimated locations with surveyed reference points at several bearings and distances. |
| Response Time | Define separate limits for signal acquisition, classification, alert generation, and operator display. A practical procurement target is a measured end-to-end alert time of a few seconds or less for supported signals. | Early warning is critical for protecting airports, prisons, public events, and sensitive facilities. | Measure latency using synchronized timestamps during repeated controlled flights. |
| Environmental Protection | For outdoor police operations, specify an enclosure rating appropriate to the site, commonly IP65 or higher for dust and water-jet protection; verify whether the rating applies to the complete deployed system. | Outdoor detectors may face rain, dust, temporary water exposure, and contamination from road or industrial environments. | Review the formal ingress-protection test report and inspect connectors, seals, antennas, and mounting accessories. |
| Operating Temperature | Select a documented operating range that covers local seasonal conditions. A common public-safety requirement is approximately −20°C to +50°C, subject to site climate and equipment configuration. | Temperature limits can affect RF sensitivity, battery capacity, displays, network equipment, and outdoor reliability. | Confirm the tested operating range for the complete system, including batteries, antennas, displays, and communication modules. |
| Power Options | Support continuous mains or vehicle power, with battery backup where temporary deployment is required. Document power input, consumption, charging time, and backup duration. | Police teams may operate from command vehicles, temporary checkpoints, rooftops, or locations without stable grid power. | Perform a runtime test under normal detection, networking, recording, and display loads. |
| Deployment Time | For rapid-response units, target setup and operational readiness within the time defined by the agency's incident-response plan. | Long setup times reduce the value of a detector during dynamic events or temporary protective missions. | Time the complete workflow from transport case opening to calibrated detection, including networking and user login. |
| Networking and Integration | Require secure IP networking, role-based access, event APIs or documented interfaces, and compatibility with the agency's command-and-control environment. | Integrated alerts can be shared with dispatchers, patrol teams, cameras, access-control systems, and incident-management platforms. | Test network operation under isolated, cellular, wired, and restricted-access conditions as applicable. |
| Cybersecurity | Require encrypted communications, authenticated users, signed or controlled firmware updates, audit logs, vulnerability-reporting procedures, and configurable data retention. | Detection systems may process sensitive location, event, and operational data and may connect to public-safety networks. | Request security documentation, access-control settings, update procedures, logging capability, and independent assessment evidence where available. |
| Data Storage and Evidence | Provide time-synchronized event logs containing alert time, location, detected signal information, operator actions, and system status. | Accurate records support incident review, legal processes, after-action analysis, and interagency coordination. | Export sample records and verify timestamps, metadata integrity, retention controls, and chain-of-custody procedures. |
| Regulatory Compliance | Confirm radio emissions, spectrum use, privacy handling, cybersecurity, import, and aviation-related requirements separately for every deployment country. | Equipment permitted in one market may require certification, frequency restrictions, authorization, or additional data controls in another. | Obtain current certificates and legal documentation from the supplier and consult the relevant national authorities before purchase. |
| Training and Usability | Require a clear alert interface, map-based visualization, configurable alert levels, multilingual documentation where needed, and operator training materials. | Consistent decisions depend on rapid interpretation by users with different technical backgrounds and language requirements. | Conduct scenario-based evaluations with actual operators and record training time, alert comprehension, and task completion rates. |
| Lifecycle Support | Evaluate firmware support period, spare-parts availability, calibration requirements, repair turnaround, software licensing, and total cost of ownership. | Police systems are expected to remain operational for years, while radio protocols and regulatory requirements can evolve. | Request a written support plan covering warranty, service-level targets, updates, calibration, obsolescence, and end-of-support notices. |
| Acceptance Testing | Use a written test plan covering detection, identification, false alarms, latency, environmental conditions, cybersecurity, integration, and operator training. | Structured acceptance testing converts marketing claims into measurable operational performance. | Define pass/fail criteria before delivery and require test records, corrective-action procedures, and final sign-off by the purchasing agency. |
