Reolink P850 8MP 16× Zoom 360° Rotating PoE Camera [Hong Kong Official Warranty]

3840x2160 (8MP) @25fps｜f=5.3-86mm, max. F1.6｜16× optical zoom｜2-year Hong Kong official warranty

Product Overview

The P850 is a wired network camera in Reolink’s PoE range. It offers an official resolution of 3840x2160 (8MP) @25fps, with an f=5.3-86mm 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”, so no separate power socket is needed at the camera location and there is no frame dropping 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 specified by the manufacturer (such as the enclosure protection rating of certain models), we will not add information 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 your order, and we will provide recommendations based on the actual environment.

Six Key Highlights

8MP Image Quality and Lens

The P850 has an official resolution of 3840x2160 (8MP) @25fps, with an f=5.3-86mm lens and a maximum aperture of F1.6.

The field of view is Horizontal 54.2°-3.6° ／ Vertical 41.7°-2.1°. This range is designed for versatility: with the same lens, a narrower angle provides clearer distant details but covers a smaller area at once; a wider angle covers a larger area, at the cost of greater edge distortion and less-defined distant details.

In practice, first measure the distance between the installation point and the target, then decide whether to mount the camera higher or lower. With the same camera, mounting it at 2.8 meters versus 3.5 meters can result in a significant difference in the actual ground area covered.

Infrared Night Vision and Full-Color Night Vision

The P850’s infrared night vision reaches up to 80 meters (260ft); it uses 7 infrared LEDs / maximum 5.5W / 850nm.

Full-color night vision: supported, with 2 spotlights / 4W / 4000K (adjustable). Infrared footage is in black and white, offering the benefits of discretion and not startling passers-by. Full-color night vision uses spotlights for illumination, preserving color information such as clothing and vehicle colors when needed, which can be practically helpful for identification afterward.

During installation, avoid pointing the lens directly at a white wall or metal awning, as reflected infrared light may cause overexposure in the center of the image and make the surrounding areas difficult to see. If this cannot be avoided, tilting the camera downward by 10 to 15 degrees will usually provide a noticeable improvement.

Smart Detection and Notifications

The P850 supports person, vehicle, animal, and motion detection. Detection is processed on the camera, and notifications are pushed only when a target category is identified, filtering out common false triggers associated with traditional motion detection, such as rain, moving tree shadows, and changes in lighting.

Notifications can be enabled or disabled individually. If you want to receive person alerts but do not want to be woken up 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 the notification directly to view the relevant clip without manually dragging along the timeline.

PoE Power and Network Connection

P850 power specifications: IEEE 802.3at, 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 there is a network connection but no power outlet.

The network interface is 1× 10M/100Mbps RJ45. Power can be supplied by a PoE-enabled 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 latency when multiple people are viewing live footage at the same time or when there is heavy interference from nearby Wi-Fi networks, whereas PoE does not.

Storage, Playback and Backup

P850 storage options: microSD up to 256GB; compatible with Reolink NVRs.

The microSD option is suitable for scenarios where only a few days of footage need to be retained and a single camera is the main focus. An NVR is better suited for multiple cameras, retaining footage for several weeks, or reviewing clips from multiple angles at once. Both can be used together: microSD as a backup and the NVR as the primary storage.

We recommend using a surveillance-grade microSD card (designed for high write endurance and resistance to high and low temperatures). Standard phone memory cards can easily fail after several months of continuous writing, and they typically fail without warning.

App, Two-Way Talk and Remote Viewing

P850 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, giving customers instructions at a shop, or asking someone to move a vehicle from a parking space.

Remote viewing is available through the Reolink App (iOS／Android). Multiple cameras can be added to the same account, with split-screen viewing supported. You can also create sub-accounts with viewing-only permissions, without allowing users to change settings or delete recordings.

Application Scenarios

The following scenarios are situations that this model is designed to handle in practice. If your installation environment differs from those listed below (such as a completely exposed slope or cable runs longer than 30 meters), we recommend contacting us for confirmation first.

• Village house exterior wall: Cover the main entrance, parking entrance, and fence, with a single PoE cable running from indoors for power.
• Shop entrance: Point it at the checkout area or gate, with person detection notifications sent directly to your phone.
• Parking space / car park: Continuous recording for reviewing footage of collisions or unauthorized parking afterward.
• Warehouse and back staircase: Stable wired connection, unaffected by metal shelving or Wi-Fi interference.
• Office corridor: Work with an NVR for centralized recording and review multiple angles at once.

Why Choose This Model

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