Quick answer: a single Ethernet run does two jobs at once, carrying video out and power in over one cable rated for roughly 100 meters before you need a repeater, which is why the Reolink RLC-820A is the pick for one sharp 4K camera at the front door, the Amcrest 5MP Turret covers a wide driveway from a single mounting post, and the Reolink RLC-510A 2-Pack wires up two cameras for less than a single flagship WiFi camera often costs alone.
Bottom Line
Reolink RLC-820A
4K resolution, human/vehicle/animal detection, and 100ft IR night vision in a wired dome. The obvious choice when you only need one camera watching one important spot, and want the sharpest picture that spot can get.
See Reolink RLC-820A →Amcrest 5MP Turret PoE Camera
A 132-degree wide-angle lens and 5MP sensor built to cover a wide driveway or side yard from a single mounting point, with a weatherproof turret housing, built-in mic, and microSD recording up to 256GB. A 4.3-star verified-buyer average.
See Amcrest 5MP Turret →Reolink RLC-510A (2-Pack)
5MP with the same person/vehicle/animal detection as the pricier Reolink model, sold as a pair. Wiring up front and back coverage for close to what one premium single camera costs.
See Reolink RLC-510A 2-Pack →None of these three cameras use WiFi at all. Each one runs on a single Ethernet cable that carries both its network connection and its power, which changes how you shop for a camera more than most spec sheets let on. Here's the full breakdown.
PoE Camera Spec Comparison
All three cameras connect over standard Ethernet and speak ONVIF, so third-party NVR software can pick them up regardless of brand. The differences show up in resolution, field of view, and how many cameras you get per purchase.
| Feature | Reolink RLC-820A | Amcrest 5MP Turret | Reolink RLC-510A (2-Pack) |
|---|---|---|---|
| Resolution | 4K (8MP) | 5MP (2592x1944) | 5MP |
| Form factor | Dome | Turret | Bullet |
| Power/connection | PoE (Ethernet) | PoE (Ethernet) | PoE (Ethernet) |
| Lens/field of view | Standard fixed lens | 132° wide angle | Standard fixed lens |
| Night vision range | Up to 100ft IR | Up to 98ft IR | Up to 100ft IR |
| Smart detection | Human/vehicle/animal | AI-based (check listing for categories) | Person/vehicle/animal |
| Weatherproofing | Outdoor-rated | Weatherproof (heavy-duty housing) | Outdoor-rated |
| Local storage | MicroSD up to 512GB | MicroSD up to 256GB; NVR supported | MicroSD up to 512GB |
| Cameras included | 1 | 1 | 2 |
| NVR or PoE switch included | No | No | No |
| Price | $$ | $$ | $$ |
Price tiers are approximate. $ = under $50, $$ = $50 to 150, $$$ = $150 to 300, $$$$ = over $300. Tap any link for the current Amazon price.
None of these three ship with a PoE switch, injector, or NVR. Each is a standalone camera, and you'll need to supply the power source yourself, which is covered in the installation section below.
What PoE Camera Owners Actually Report
Reolink and Amcrest both sell primarily to the DIY and small-business surveillance crowd rather than the smart-home gadget crowd, so the review themes skew more technical than a typical WiFi camera listing.
Reolink RLC-820A
Owners who already run a PoE switch or NVR describe setup as close to plug-and-play, with the camera showing up on the network within minutes. The recurring theme among reviewers is that image quality at 4K is a noticeable step up from Reolink's older 5MP models, particularly at night. The most common friction point is on the buyer's end, not the camera's: people who assumed the listing included a power source and had to separately source a PoE switch or injector.
Amcrest 5MP Turret PoE Camera
Amcrest's PoE lineup draws consistent praise for the wide field of view, with owners describing full driveway coverage from a single post-mounted camera that would otherwise take two narrower cameras. Some reviewers note the Amcrest View Pro app is less polished than Reolink's app, and that getting the most out of the camera means pairing it with third-party NVR software rather than relying on Amcrest's own recording tools.
Reolink RLC-510A
As the budget option in this trio, the RLC-510A draws praise less for image quality and more for making a multi-camera wired system affordable. Owners running the 2-pack across a front and back yard describe the person/vehicle detection as accurate enough to cut down on false alerts from passing cars and blowing branches, which is the main complaint on cheaper WiFi cameras that lack the same AI filtering.
Jacob’s read on this category
The camera is the easy part of a PoE install. The real decision is whether you're willing to pull Ethernet through a wall, attic, or conduit to get there, and whether you already own (or want to buy) a PoE switch. If you answer yes to both, PoE cameras are the most reliable security hardware you can put outside a house: no battery to recharge, no WiFi signal for anyone to jam, and a full-resolution stream that doesn't degrade because a neighbor's router is hogging the 2.4GHz band. If pulling cable isn't realistic in your situation, don't force it. Go read our guide to outdoor cameras for renters instead, since running Ethernet through someone else's walls usually isn't an option anyway.
Why PoE Beats WiFi for This Job
The short version: a wired camera cannot be jammed, and it cannot drop frames because your router is busy streaming something else.
Every WiFi camera, no matter how good, shares one weakness: it depends on a radio signal reaching a router that has to juggle every other device in the house. Cheap RF jammers and WiFi deauthentication tools are widely known and trivially available, and disabling a wireless camera's connection before a break-in is a documented tactic. A PoE camera has no WiFi radio to jam in the first place. The only way to take it offline is to physically cut the cable, which is a much harder and more obvious act than sitting in a car with a jammer.
Power is the other half of the equation. A battery-powered WiFi camera needs recharging every few weeks depending on activity level, and a wired-but-WiFi camera still needs an outlet near the mounting point, which most exterior walls don't have. PoE solves both problems with the same cable: continuous power, no batteries, no separate electrician visit for an outdoor outlet.
The tradeoff is installation effort. Running Ethernet through a wall, attic, or underground conduit takes more work than pairing a WiFi camera with your phone. If you already have Ethernet infrastructure in your home, or you're comfortable running a cable yourself, the tradeoff favors PoE heavily. If you'd rather avoid any wiring at all, our guide to security cameras without a subscription covers strong WiFi options that skip both the cable and the monthly fee.
What You Need to Actually Install One
None of the three cameras above include a power source. Here's what fills that gap.
Reolink's broader camera catalog spans both PoE and pure WiFi models. If you're deciding between the two approaches for the same yard, our Eufy vs Reolink comparison covers how Reolink's WiFi lineup stacks up against a battery-powered competitor for buyers who'd rather skip the cable entirely.

Frequently Asked Questions
Behind This Comparison
PoE cameras get skipped over by a lot of "best security camera" roundups because the audience is assumed to want WiFi and a phone app, full stop. We picked these three because they cover the three real use cases for a wired setup: one sharp camera at a single high-value spot, one wide-angle camera for open ground, and an affordable two-camera pair for buyers wiring up more than one entry point. Specs above were cross-checked against each product's current Amazon listing title and description. We do not run our own NVR bench tests, so treat the owner-report themes as a supplement to, not a replacement for, the manufacturer spec sheet.
