FlySpark N-DEFENDER Passive Multi-Band Drone Detection & Video Interception System | 1.08GHz–8.26GHz FPV Drone Threat Sensor

A: FlySpark N-DEFENDER is a passive multi-band FPV drone detection and analog video interception system. It detects drones by RF emissions, verifies analog video in hardware and can display the drone’s live camera feed to the operator.

A: The listed price of the FlySpark N-DEFENDER Standard Portable Kit is ₹2,48,000.

A: The system first detects the drone’s RF signal, verifies the threat with hardware video proof and then displays the drone’s live analog FPV feed where legally permitted.

A: No. N-DEFENDER is a passive receive-only detection and video-monitoring system, not a jammer.

A: No. It is fully passive and does not transmit RF energy.

A: No. It detects and verifies drone activity but does not disable, hijack, jam or spoof the drone.

A: It is optimized for FPV drones using analog video links across 1.2/1.3GHz, 3.3GHz, 5.8GHz and 7.2GHz-class bands.

A: Yes. Analog FPV drone detection is the primary purpose of the system.

A: No. It does not decode encrypted digital video. Wideband digital RF activity can be classified separately, but live video confirmation is for unencrypted analog FPV signals.

A: It scans 1.08–2.36GHz, 3.10–3.80GHz, 4.87–6.06GHz and 6.00–8.26GHz.

A: It scans more than 100 channels per sweep round.

A: A full four-band sweep takes approximately 6 seconds.

A: A hot-signal fast path can tune and probe a suspect channel in approximately 0.5 seconds.

A: Sensitivity is approximately -90dBm to -96dBm depending on band and front end.

A: Analog FM CVBS video with PAL and NTSC auto-detection is supported.

A: Hardware video proof means the system confirms genuine composite-video sync and a recognized video standard before raising a verified analog-drone alarm.

A: It prevents RF energy alone from triggering a verified alarm, reducing false positives from cellular towers, broadband noise, harmonics and random RF bursts.

A: It can show frequency, band, signal strength, confidence score, estimated range, lock time, battery state and video-confirmation state.

A: Yes, when the drone uses unencrypted analog FPV video and the signal is successfully verified.

A: Yes. Its hardware OSD can show system state, band, frequency, signal strength, range, lock timer and battery level.

A: Range depends on VTX power, antenna, terrain and RF conditions. Example line-of-sight estimates are about 1.8km at 5.8GHz and 8km at 1.2/1.3GHz for a 200mW VTX.

A: Under suitable line-of-sight conditions, a 600–800mW transmitter may be detected up to approximately 15km on 1.2/1.3GHz.

A: Yes. It provides signal-strength-based range estimation and supports field calibration.

A: Yes. It monitors signal trends and can indicate approaching or receding behavior.

A: It can remain locked to a verified threat while scanning other bands, then verify a stronger or closer threat before handover.

A: Alerts include a touchscreen warning banner, siren, RGB beacon, OSD video alert, serial telemetry and event log.

A: Yes. It uses a 3.5-inch, 480×320 color touchscreen.

A: Yes. Composite AV output supports a monitor, goggles, recorder or relay equipment.

A: Yes. A USB serial command API and telemetry output support dashboard and larger security-system integrations.

A: Yes. It is designed for power plants, refineries, substations, dams, data centers and other high-value infrastructure requiring passive monitoring.

A: Yes. It can help detect analog FPV drones used for contraband delivery and provide authorized video evidence.

A: Yes. It can detect long-range FPV and smuggling-drone video links, including lower-frequency bands.

A: It can provide passive perimeter awareness where legally approved because it does not transmit or interfere with aviation systems.

A: Yes. It can provide authorized passive FPV drone awareness and video proof for stadiums, rallies, motorcades and public events.

A: Yes. A vehicle package can include power integration, external antenna routing, mounting and display support.

A: Yes. Fixed-site packages can be configured for prisons, critical infrastructure, government campuses and industrial facilities.

A: Yes. Directional antenna packages can improve site-specific monitoring and directional awareness.

A: The standard configuration includes the N-DEFENDER unit, passive multi-band receiver architecture, touchscreen, alerting stack, AV output, rechargeable power system and per-band antenna support.

A: Yes. Operator training and deployment support can be supplied to approved customers.

A: It is strongest against analog FPV links. It does not decode encrypted digital video, disable drones or replace radar and optical systems for silent threats.

A: Antenna placement, terrain, obstacles, RF noise, line-of-sight and deployment weather can affect performance.

A: Users must follow privacy, RF-monitoring and aviation laws, site permissions and security SOPs. Signal monitoring must be legally authorized.

A: The system includes one-year manufacturing-defect support under approved and normal use. Misuse, impact, water ingress, incorrect charging or unauthorized modification may not be covered.
