About the Hikvision DS-2CD2023G2-I(4mm)

The Hikvision DS-2CD2023G2-I(4mm) is a rugged outdoor-grade bullet form factor designed to withstand exposure to weather, vandalism, and direct sunlight. At 1080p the camera produces detail dense enough to identify faces inside ~10 meters and read European license plates inside 8 meters under daylight conditions. Medium IR range (20–40 m) is appropriate for typical residential driveways, small commercial perimeters, and back-of-house loading bays where reach beyond ~30 m is rarely needed at night. 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

Parking lot & open yard

The 84° field of view spans roughly 72 meters at the camera's effective range — wide enough to monitor multiple parking rows from a single mounting point.

Entrance, lobby & vestibule

The 84° 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.

Strengths

•40m effective range supports outdoor perimeter and parking-lot deployments

Considerations

•No notable limitations for the intended class of installations

Installation tips for the DS-2CD2023G2-I(4mm)

Mount at 4–6 m height angled 10–20° downward — high enough to deter tampering, low enough to preserve face detail at 28m.

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.

Coverage geometry & DORI distances

At a 5-metre standoff the Hikvision DS-2CD2023G2-I(4mm) covers about 9.0 m of scene width; at 10 m that grows to 18.0 m, and at 20 m to 36.0 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 43 m, observe up to 17 m, recognise up to 9 m, and produce identification-grade detail (the ≥250 px/m bar used by Polish and EU courts as evidentiary) up to 4 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic — the geometry above assumes the 4mm lens declared by the manufacturer.

Power & cabling

The Hikvision DS-2CD2023G2-I(4mm) draws an estimated 7.5 W under typical load (with the IR illuminator engaged where applicable), placing it in the 802.3af (Class 3, ≤15.4 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. Even a narrowly-aimed bullet camera can incidentally record passers-by, so the Art. 13 sign at the entry point applies regardless of how tightly the lens is framed.

Installer time & cost (rough estimate)

A typical EU installer quotes 3–4 h of labour per bullet camera of this class (approximately €135–€185 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 Hikvision DS-2CD2023G2-I(4mm) suitable for outdoor installation?

Yes for the IP66/IP67-rated variant of this model. Bullet and dome bodies in the Hikvision range survive direct rain, snow and UV; check the IP / IK rating against your environment (IP66 for rain/dust, IK10 for vandal-prone locations).

What PoE class powers the Hikvision DS-2CD2023G2-I(4mm)?

The camera draws roughly 7.5 W in steady-state operation, requiring a 802.3af (Class 3, ≤15.4 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 Hikvision DS-2CD2023G2-I(4mm) consume per day?

At 2.1MP (1920×1080) resolution, 15 fps H.265 continuous recording, the DS-2CD2023G2-I(4mm) produces approximately 8 GB per day — about 240 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 Hikvision DS-2CD2023G2-I(4mm) identify a person?

Per EN 62676-4:2025 pixel-density thresholds, this camera identifies (≥ 250 px/m on the target) up to about 4 m, recognises a person up to 9 m, observes general activity up to 17 m, and detects motion up to 43 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 Hikvision DS-2CD2023G2-I(4mm) use?

Typical ingest is 3 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.
