REOLINK P334 (8 MP/2.8 MM) - DOME PoE IP CAMERA

Wired PoE power: one cable and genuine 24/7 recording

The P334 is a wired IEEE 802.3af PoE camera, meaning power and video travel down a single twisted-pair cable and the mounting point needs no socket, no power brick and no battery. That is the fundamental difference from the battery-powered Argus and Go lines: the P334 never sleeps, never waits for a PIR trigger and records continuously around the clock, so every minute of the past day is in the archive rather than only the fragments around motion. Consumption of roughly 12 W means an eight-port PoE switch with a 60 to 65 W budget will comfortably carry five such cameras, while a full set of eight calls for a switch rated from 100 W upwards. The camera can alternatively be fed locally from 12 V if you have no PoE switch, but then you are pulling two cables instead of one and much of the point of a wired install is lost. The wired link brings one more benefit that owners usually appreciate only after installation: it does not depend on Wi-Fi quality, does not stutter under a 4K stream and does not drop out when a neighbour switches on a microwave.

4K at 25 frames per second: what eight megapixels actually buy

The 1/2.49 inch sensor produces 3840 by 2160 pixels at 25 frames per second, four times the pixel count of a common Full HD camera, and that reserve is exactly what lets you zoom into a recorded frame without the face dissolving into coloured mush. The difference shows up not during live viewing but afterwards, when an incident has already happened and you need to extract a detail from the archive: the make of a car, the lettering on a jacket, what somebody was carrying. Twenty-five frames per second at 4K is not a formality either: at 15 fps a car passing at 30 km/h smears noticeably, while at 25 fps the same pass can be stepped through frame by frame. The comparatively large 1/2.49 inch sensor also helps in awkward lighting, for example when a person stands against a bright sky or a street lamp. The trade-off is equally plain: a 4K stream is several times heavier than Full HD, so memory cards and recorder disks fill up faster and the link back to the recorder really does need to be wired.

A 2.8 mm lens at 105 degrees: wide coverage and what it costs

The 2.8 mm focal length with an F/1.6 aperture gives roughly 105 degrees horizontally and around 56 vertically, a genuinely wide view in which one camera covers a typical private yard or the sales floor of a small shop in its entirety. The fast F/1.6 aperture matters more than it sounds: a wider aperture pushes more light onto the sensor at dusk, which delays the moment the camera has to fall back to illuminated night mode. The downside of a wide angle is pixel distribution, because the same eight megapixels are stretched across a broader scene, so beyond fifteen to twenty metres detail shrinks and reading a plate or small text becomes hard. A practical rule for this optic: up to ten metres you get a recognisable face, up to twenty you can reliably tell clothing and actions apart, and past twenty-five metres you are left with a general view and the fact that somebody was there. If plate reading at the gate is the actual requirement, it is more honest to give that spot its own camera with narrower or varifocal optics and leave the P334 to cover the area.

Night vision: 30 metres of infrared plus a white spotlight

Night mode rests on two light sources: an infrared array effective to about thirty metres and a white LED spotlight of roughly 4.3 W at 6500 K. The infrared mode is invisible from outside and gives a monochrome picture across the full illumination range, whereas the spotlight comes on when colour matters more and turns a grey silhouette into a person in a jacket of a specific colour. Thirty metres is no longer a porch-and-gate proposition but a full yard, a drive along a fence or the parking area in front of a facade, and this is precisely where the P334 pulls away from cheaper models limited to ten metres. Keep the physics of infrared in mind, though: the stated range means you will see movement and a silhouette at thirty metres, not a recognisable face, because illumination falls off with the square of distance. The second classic pitfall is the white-out effect: if the camera looks through glass or sits flush against a wall, infrared bounces straight back into the lens and washes the frame out, so mount it clear of glazing and of the eaves.

Person and vehicle detection, H.265 and how much archive fits

Analytics run inside the camera, separating people and vehicles from generic motion, so alerts arrive for things that matter rather than for every branch or passing cloud shadow. This is the feature that decides whether the system is still in use in week three: a camera without object classification buries its owner in dozens of daily pushes, and the outcome is always the same, the notifications get switched off. The H.265 codec compresses 4K roughly twice as efficiently as H.264, which translates directly into archive depth: a 256 GB microSD card, the maximum this model accepts, holds approximately three to four days of continuous 4K, and weeks if you record on events only. For a shop or any site that needs a thirty-day archive, a memory card is simply the wrong storage tier and the camera belongs on a Reolink recorder with a multi-terabyte disk. The stream is available over RTSP and stills can be pushed to FTP, so third-party video servers are possible, although the full configuration set stays inside the Reolink app.

A metal eye-ball housing, IP67 and where to put the camera

The eye-ball design is a ball seated in a base roughly 117 mm across: you aim it after mounting and then lock it, and unlike a bullet camera on a long arm it is hard to twist by hand from below. The housing is metal, the camera weighs 526 grams and the IP67 rating covers full dust protection plus temporary immersion, which is more than enough for wind-driven rain on an exposed facade. The -10 to +55 °C operating range deserves a sober look: it covers most winters in this region, but for an exposed position where -20 is routine it is wiser to tuck the camera under an overhang or choose a model with a wider range. Typical placements are the facade above an entrance, the corner of a building, a shop floor, a warehouse, an office corridor or the customer parking in front of a business, anywhere that needs wide coverage plus a continuous archive. It is out of place on a long narrow driveway, where a narrower lens serves better, and at any point where no cable can be run, for which the catalogue offers the battery Argus line.

How it differs from neighbouring Reolink models in this catalogue

Its nearest rival in the catalogue is the P324 2.8 mm: the same eye-ball body, the same angle and the same PoE, but 5 MP instead of 8, so if you only need to establish the fact of an event and keep an eye on the yard, the gap will not pay for itself. The opposite case is the RP-PCT8M 2.8 mm, which on paper is the same 8 MP, 2.8 mm eye-ball class for more, making the P334 the better buy in a straight comparison. The P344 raises resolution to 12 MP, which earns its keep where you routinely zoom into recorded frames, for example over a shop till. If the real task is reading plates or watching a distant point, the P434 2.8-8 mm with its varifocal lens is the more logical choice, because you tune the angle to the scene instead of living with a fixed 105 degrees. Finally, for a seamless wide panorama the catalogue has the twin-lens Duo Series P757, though that is a different budget and a different class of task.

Send us the dimensions of the yard or the premises and the number of points you need covered, and we will work out how many P334 units it takes, which PoE switch will carry them and what disk size gives the archive depth you want.
