About the Hikvision DS-2TD1228-7/QA
The Hikvision DS-2TD1228-7/QA is a weather-sealed bullet housing optimized for perimeter, parking, and exterior building installations. Sub-megapixel resolution is suitable only for general overview footage — useful for movement detection but insufficient for facial recognition or license-plate reading. 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 narrow field of view trades coverage area for pixel density at distance — the right choice when you need to read faces or plates far from the camera, e.g., long corridors, gate approaches, ANPR installations.
Best use cases for this camera
Long corridor & aisle monitoring
The 24.9° narrow angle is intentionally tuned for corridor work — it concentrates pixel density along the length of the hallway rather than wasting resolution on the side walls. Mount at the far end facing along the corridor.
Strengths
- •300m effective range supports outdoor perimeter and parking-lot deployments
Considerations
- •Resolution limits forensic digital zoom — recorded faces beyond ~12m may not be identifiable
- •Short IR range limits night usability to indoor or close-proximity scenarios
- •Narrow angle requires more cameras to cover wide areas — plan camera count accordingly

Field of View Visualization
Night Vision Performance
Daytime
Full 0.0MP (256×192) resolution at 24.9° field of view. Effective identification range up to 300m in good lighting conditions.
Nighttime (IR)
Built-in IR LEDs illuminate up to 15m in complete darkness. Switches to B/W mode for clear night footage.
Installation tips for the DS-2TD1228-7/QA
Pair with low-cost ambient lighting (motion-triggered LED floods) to extend usable identification distance beyond the IR limit.
Plan cabling for multiple cameras to cover wide areas — at 24.9° you cover roughly 4 m of width per camera at 10 m distance.
Coverage geometry & DORI distances
At a 5-metre standoff the Hikvision DS-2TD1228-7/QA covers about 2.2 m of scene width; at 10 m that grows to 4.4 m, and at 20 m to 8.8 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 171 m, observe up to 68 m, recognise up to 34 m, and produce identification-grade detail (the ≥250 px/m bar used by Polish and EU courts as evidentiary) up to 17 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic — the geometry above assumes the 6.9mm lens declared by the manufacturer.
Power & cabling
The Hikvision DS-2TD1228-7/QA 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 turret 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 4–5 h of labour per turret camera of this class (approximately €180–€230 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-2TD1228-7/QA 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-2TD1228-7/QA?
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-2TD1228-7/QA consume per day?
At 0.0MP (256×192) resolution, 15 fps H.265 continuous recording, the DS-2TD1228-7/QA produces approximately 2 GB per day — about 60 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-2TD1228-7/QA identify a person?
Per EN 62676-4:2025 pixel-density thresholds, this camera identifies (≥ 250 px/m on the target) up to about 17 m, recognises a person up to 34 m, observes general activity up to 68 m, and detects motion up to 171 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-2TD1228-7/QA use?
Typical ingest is 2 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.
