About the Merit Lilin AHD765A6
The Merit Lilin AHD765A6 is a weather-sealed bullet housing optimized for perimeter, parking, and exterior building installations. Sub-megapixel resolution is suitable only for general overview footage. It is 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 46.5° 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
Considerations
- •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
Coverage at Different Distances
| Distance | Coverage Width | Coverage Area | Use Case |
|---|---|---|---|
| 5m | 4.3m | 21 m² | Entrance, corridor |
| 10m | 8.6m | 86 m² | Room, retail aisle |
| 15m | 12.9m | 193 m² | Warehouse, parking row |
| 20m | 17.2m | 344 m² | Parking row, courtyard |
| 30m | 25.8m | 773 m² | Parking lot, yard |
| 50m | 43.0m | 2148 m² | Perimeter, large area |
Field of View Visualization
Night Vision Performance
Daytime
Full N/A resolution at 46.5° field of view. Effective identification range up to 0m 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 AHD765A6
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 46.5° you cover roughly 9 m of width per camera at 10 m distance.
Coverage geometry & DORI distances
At a 5-metre standoff the Merit Lilin AHD765A6 covers about 4.3 m of scene width; at 10 m that grows to 8.6 m, and at 20 m to 17.2 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 88 m, observe up to 35 m, recognise up to 18 m, and produce Identify-level detail (250 px/m in the EN 62676-4 DORI scale) up to 9 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic; the geometry above assumes the 6mm lens declared by the manufacturer.
Power & cabling
The Merit Lilin AHD765A6 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 pricing at 2024-2025 rates; actual quotes vary by region, mounting height, and site conditions. Excludes hardware, transport, permits, and VAT.
Frequently asked questions
Is the Merit Lilin AHD765A6 suitable for outdoor installation?
Yes for the IP66/IP67-rated variant of this model. Bullet and dome bodies in the Merit Lilin 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 Merit Lilin AHD765A6?
The camera draws roughly 7.5 W in steady-state operation, requiring an 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.
