About the Pelco IWP133-1ERS
The Pelco IWP133-1ERS is a low-profile dome enclosure that blends into ceilings, vandal-resistant by design and harder to tamper with than bullet cameras. 720p HD resolution captures enough detail for basic identification only at close range: on the same lens it reaches about two thirds of the distance a 1080p camera does, and loses face detail beyond that. 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
Entrance, lobby & vestibule
The 112° 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
- •112° wide field of view reduces the number of cameras needed per area
- •Vandal-resistant dome housing harder to tamper with than bullet form factor
Considerations
- •Resolution limits forensic digital zoom; recorded faces beyond ~12m may not be identifiable

Field of View Visualization
Night Vision Performance
Daytime
Full 1.2MP (1280×960) resolution at 112° field of view. Effective identification range up to 2m in good lighting conditions.
Nighttime (IR)
Built-in IR LEDs illuminate up to 25m in complete darkness. Switches to B/W mode for clear night footage.
Installation tips for the IWP133-1ERS
Ceiling-mount at 2.5-3.5 m for indoor use; for vandal-prone outdoor locations use a wall mount with the lens facing outward and downward.
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, because peripheral pixel density drops with wide angles.
Coverage geometry & DORI distances
At a 5-metre standoff the Pelco IWP133-1ERS covers about 14.8 m of scene width; at 10 m that grows to 29.7 m, and at 20 m to 59.3 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 17 m, observe up to 7 m, recognise up to 3 m, and produce Identify-level detail (250 px/m in the EN 62676-4 DORI scale) up to 2 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic; the geometry above assumes the 2.8mm lens declared by the manufacturer.
Power & cabling
The Pelco IWP133-1ERS 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 dome 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 dome 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 Pelco IWP133-1ERS suitable for outdoor installation?
Yes for the IP66/IP67-rated variant of this model. Bullet and dome bodies in the Pelco 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 Pelco IWP133-1ERS?
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.
How much storage does the Pelco IWP133-1ERS consume per day?
At 1.2MP (1280×960) resolution, 15 fps H.265 continuous recording, the IWP133-1ERS produces approximately 5 GB per day, about 150 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 Pelco IWP133-1ERS identify a person?
By the DORI thresholds of EN 62676-4 (Identify at 250 px/m on the target, a density the 2025 edition calls Characterise), this camera reaches Identify level up to about 2 m, recognises a person up to 3 m, observes general activity up to 7 m, and detects motion up to 17 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 Pelco IWP133-1ERS 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.
