Reolink P437 8MP 5× Zoom PoE Camera [Hong Kong Official Warranty]

3840x2160 (8MP) @25fps｜f=2.7-13.5mm, max. F1.6｜5× optical zoom｜2-year Hong Kong official warranty

Product Introduction

The P437 is a wired network camera in Reolink's PoE series. It is officially rated at 3840x2160 (8MP) @25fps, with an f=2.7-13.5mm lens and a maximum aperture of F1.6. It is designed as a fixed-installation solution where one network cable handles both power and video transmission. No power socket is needed at the camera location, and there are no frame drops caused by wireless interference.

All specifications on this page are taken from the Specifications table on Reolink's official product page, without estimation or conversion. For items not listed officially, such as the enclosure protection rating of certain models, we will not add details ourselves and will indicate this below.

If you are unsure how many cameras you need or whether an NVR is required, send us your floor plan or on-site photos before placing an order. We will provide recommendations based on your actual environment.

Six Key Highlights

8MP Image Quality and Lens

The P437 is officially rated at 3840x2160 (8MP) @25fps, with an f=2.7-13.5mm lens and a maximum aperture of F1.6.

The field of view is horizontal 100°-31° / vertical 55°-17° / diagonal 123°-39°. This is a standard lens design: the narrower the viewing angle, the clearer distant details will be, but the smaller the area covered at once; the wider the viewing angle, the larger the coverage, at the cost of greater edge distortion and less sharp distant details.

In practice, measure the distance from the installation point to the target first, then decide whether to mount the camera higher or lower. With the same lens, the actual ground coverage can differ significantly when mounted at 2.8 meters versus 3.5 meters.

Infrared Night Vision and Color Night Vision

P437 infrared night vision: up to 30 meters (100ft); 4 infrared LEDs / 2.8W / 850nm.

Color night vision: supported, with 2 spotlights / 3.2W / 6500K / 400 lumens. Infrared images are black and white, making them discreet and less likely to disturb passers-by. Color night vision uses spotlights for illumination and can retain color information such as clothing and vehicle body colors when needed, which is practically useful for identification after an incident.

During installation, avoid pointing the lens directly at a white wall or metal canopy. Otherwise, reflected infrared light may cause overexposure in the center of the image while making the surroundings difficult to see. If this cannot be avoided, tilting the camera downward by 10 to 15 degrees usually provides a noticeable improvement.

Smart Detection and Notifications

The P437 supports person, vehicle, animal, and motion detection. Detection is processed on the camera, and notifications are sent only when the specified target categories are detected. This filters out common sources of false alerts from traditional motion detection, such as rain, swaying tree shadows, and changing lights.

Notifications can be enabled or disabled individually. If you want to receive person alerts but do not want to be woken by cats or dogs at night, simply turn off animal detection notifications; recording will continue as usual. Settings can be adjusted for each camera in the Reolink App.

When used with microSD or NVR recording, you can tap directly into the relevant clip when a notification arrives, without manually dragging along the timeline.

PoE Power and Network Connection

P437 power specifications: IEEE 802.3af, 48V Active. A single network cable provides both power and video transmission, so no separate power cable or socket is required at the camera location. This is the cleanest solution for locations such as exterior walls, ceilings, and village-house rooftops where a network cable is available but no power outlet is present.

The network interface is 1× 10M/100Mbps RJ45. Power can be supplied by a PoE-compatible Reolink NVR or a standalone PoE Switch (which must comply with the standards listed above).

The practical benefit of a wired connection is stable bandwidth: wireless cameras may experience frame drops and delays when multiple people are viewing live footage simultaneously or when there is heavy interference from nearby Wi-Fi networks, whereas PoE does not.

Storage, Playback and Backup

P437 storage options: microSD up to 256GB; compatible with Reolink NVR.

The microSD option is suitable for scenarios requiring only a few days of retention and primarily involving a single camera. The NVR option is suitable for multiple cameras, retention of several weeks, or reviewing footage from multiple angles at once. Both can be used together: microSD as backup and NVR as the primary storage.

We recommend using a surveillance-grade microSD card with high write endurance and resistance to high and low temperatures. Standard phone cards can easily fail after several months of continuous writing, usually without warning.

App, Two-Way Talk and Remote Viewing

P437 audio: built-in microphone and speaker (supports two-way audio).

In the Reolink App, press and hold the talk button to speak to people on-site. This is useful for receiving packages at the door, reminding customers at a shop, or asking someone to move a vehicle from a parking space.

Remote viewing is available through the Reolink App (iOS / Android). The same account can add multiple cameras and supports split-screen viewing. You can also create sub-accounts with viewing-only permissions, without access to change settings or delete recordings.

Suitable Applications

The following scenarios are situations that this model can handle in actual use. If your installation environment differs from those listed below, such as a completely exposed slope or cable runs exceeding 30 meters, we recommend confirming with us first.

• Village house exterior walls: Cover the main entrance, parking area entrance, and fences, with a single PoE cable running from indoors for power supply
• Shop entrances: Pointed at the cashier area or gate, with person detection notifications sent directly to your phone
• Parking spaces / car parks: Continuous recording for reviewing collision or unauthorized parking incidents afterwards
• Warehouses and rear stairwells: Stable wired connection, unaffected by metal shelving or Wi-Fi interference
• Office corridors: Combine with an NVR for centralized recording and review multiple angles at once

Why Choose This Model

• Wired power supply means the camera does not need to be installed near a power outlet, minimizing installation limitations
• AI detection is processed on the device, providing a high notification hit rate and fewer false alarms
• Local storage is the primary option (microSD up to 256GB), with no monthly fee required to view recordings
• The Reolink App manages all cameras in one app and supports sub-account sharing
• 2-year Hong Kong authorized version manufacturer warranty with local support
