About the INSTAR IN-9820 4K
The INSTAR IN-9820 4K is a pan-tilt-zoom platform giving operators the ability to follow targets, scan large areas on auto-tour, and zoom in for identification. At 8MP the camera covers more area per device while preserving enough pixels-per-meter for legal evidence quality at typical installation distances. A short-range IR illuminator (≤20 m) handles entrance vestibules, indoor corridors, and small enclosed spaces. Beyond 20 meters the IR fall-off causes faces to lose detail in pure darkness. A wide 80–120° angle covers a large room or open area from a single mounting position, making it ideal for retail floors, conference rooms, and small parking lots.
Best use cases for this camera
Entrance, lobby & vestibule
The 113° field of view captures the entire entrance and surrounding waiting area from a single ceiling mount. Useful for capturing visitors as they enter and leave.
Large area patrol & target tracking
PTZ control enables operator-initiated tracking of suspicious activity, scheduled tours of preset positions overnight, and forensic zoom into recorded footage. Best paired with a wide-angle "overview" camera that triggers the PTZ via analytics.
Strengths
- •8.3MP sensor preserves detail under digital zoom on recorded footage
- •113° wide field of view reduces the number of cameras needed per area
- •PTZ control enables operator-driven tracking and pre-set tours
Considerations
- •Short IR range limits night usability to indoor or close-proximity scenarios
- •PTZ cameras only see one direction at a time — pair with a fixed overview camera to avoid blind spots
- •Higher resolution increases storage and bandwidth requirements proportionally — verify NVR capacity

Field of View Visualization
Night Vision Performance
Daytime
Full 8.3MP (3840×2160) resolution at 113° field of view. Effective identification range up to 20m in good lighting conditions.
Nighttime (IR)
Built-in IR LEDs illuminate up to 20m in complete darkness. Switches to B/W mode for clear night footage.
Installation tips for the IN-9820 4K
Mount above 4 m on a rigid pole or wall bracket — PTZ vibrations are amplified at low mounting heights and degrade image quality during pan operations.
Pair with low-cost ambient lighting (motion-triggered LED floods) to extend usable identification distance beyond the IR limit.
Position so the most important subject (entrance, cash register, gate) is in the center third of the frame — peripheral pixel density drops with wide angles.
Plan storage at roughly 33 GB per camera per day for continuous H.265 recording at 15fps — verify NVR has sufficient HDD bay capacity.
Coverage geometry & DORI distances
At a 5-metre standoff the INSTAR IN-9820 4K covers about 15.1 m of scene width; at 10 m that grows to 30.2 m, and at 20 m to 60.4 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 51 m, observe up to 20 m, recognise up to 10 m, and produce identification-grade detail (the ≥250 px/m bar used by Polish and EU courts as evidentiary) up to 5 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic — the geometry above assumes the 2.7-13.5mm lens declared by the manufacturer.
Power & cabling
The INSTAR IN-9820 4K draws an estimated 30.0 W under typical load (with the IR illuminator engaged where applicable), placing it in the 802.3at (Class 4, ≤30 W) budget. A single switch port supplies enough power without an injector. Cabling: stick to Cat6 STP for runs up to 100 m end-to-end — beyond that, add an inline PoE extender or move to fibre with a media converter at the camera end. On outdoor runs, route through ø25 PVC or PE conduit to keep the cable shielded from UV and rodents.
Privacy & legal (GDPR / RODO)
Any camera operating in a publicly accessible area falls under GDPR (RODO in Poland) — Art. 13 obliges the data controller to post an information sign at every entry point with controller name, DPO contact, lawful basis (typically Art. 6(1)(f) legitimate interest for property protection), purpose, and retention period. The INSTAR IN-9820 4K's PTZ pan range can sweep into neighbouring properties or public roads; document allowed pan limits in the installation record and configure privacy masks (see INSTAR's web-UI under "Privacy Mask") for any window or doorway you cannot legally surveil.
Installer time & cost (rough estimate)
A typical EU installer quotes 5–6 h of labour per ptz camera of this class (approximately €225–€275 excluding hardware), broken down as bracket mounting, cable termination at both ends, on-site commissioning, and a brief operator handover. Allow extra time for high mounts (>4 m), exterior installations requiring scaffolding, or sites where cable routing demands wall penetrations or conduit work.
Indicative EU 2024-2025 pricing — actual quotes vary by region, mounting height, and site conditions. Excludes hardware, transport, permits, and VAT.
Frequently asked questions
Is the INSTAR IN-9820 4K suitable for outdoor installation?
INSTAR PTZ models are generally designed for outdoor use with IP66 ingress rating and -30°C to +60°C operating range. Mount on a rigid pole at ≥ 4 m to dampen wind-driven vibration that would degrade the live image during pan operations.
What PoE class powers the INSTAR IN-9820 4K?
The camera draws roughly 30.0 W in steady-state operation, requiring a 802.3at (Class 4, ≤30 W) switch port. A single Cat6 STP cable carries both data and power up to 100 m — beyond that, add an inline extender or convert to fibre near the camera.
How much storage does the INSTAR IN-9820 4K consume per day?
At 8.3MP (3840×2160) resolution, 15 fps H.265 continuous recording, the IN-9820 4K produces approximately 33 GB per day — about 990 GB per month. Motion-only or event-triggered recording typically cuts that by 40–70 % depending on scene activity. Plan NVR HDD capacity for the longest retention period required by your privacy policy or insurance contract.
Up to what distance can the INSTAR IN-9820 4K identify a person?
Per EN 62676-4:2025 pixel-density thresholds, this camera identifies (≥ 250 px/m on the target) up to about 5 m, recognises a person up to 10 m, observes general activity up to 20 m, and detects motion up to 51 m. Identification distance assumes daylight or full IR illumination on the target — at the limits of the IR cone the effective identify distance shrinks roughly 30 %.
What network bandwidth does INSTAR IN-9820 4K use?
Typical ingest is 12 Mbps for the main stream (H.265, medium scene complexity, 15 fps) plus ~0.5 Mbps for a low-resolution sub-stream used by mobile clients. For a 16-camera installation of this class, plan a 50–100 Mbps NVR uplink and a dedicated VLAN for camera traffic.
