Prime Day is the rare stretch when security cameras, video doorbells, and smart locks all fall to their lowest prices of the year, and the 2026 event is no exception. Starting a security system can be intimidating, but it doesn’t have to be cost prohibitive. It runs June 23 to 26, and nearly every deal below is a members-only price, so you’ll want a Prime membership; a free 30-day trial covers the whole event.

Arlo Essential Pan Tilt Security Camera 2K $33.00 (was $99.99)

A wired pan-tilt camera that rotates to cover a whole room, with six months of service included

The Arlo Essential Pan Tilt 2K at $33 is the easiest security upgrade to justify this Prime Day, 67% off its $99.99 list price. Instead of a fixed view, it pans and tilts to track a person or pet across a room, so one camera covers a space that would otherwise take two. The 2K sensor is sharp enough to make out a face near the door, it plugs into wall power so you never swap batteries, and it holds up under a covered porch as well as indoors. Six months of Arlo Secure Plus is included for cloud recording, person and package detection, and animated previews. For covering a living room, a nursery, or an entryway, this is the pick.

Blink Outdoor 4 (4-Camera System) $139.99 (was $399.99)

Wireless outdoor coverage with 2-year battery life, 65% off

The Blink Outdoor 4 four-camera kit at $139.99 is the value pick for covering the outside of a house, 65% off. Each camera is wireless and runs about two years on the included batteries, so there’s no wiring and no annual swap. They record 1080p with person detection and push alerts to the Blink app and Alexa. A Blink subscription adds cloud clip storage, or you can keep clips local with a Sync Module. For blanketing a yard on a budget, four cameras for $140 is the deal.

Arlo Essential Indoor Camera 2K (2nd Gen) $14.00 (was $79.99)

The cheapest real security camera in the sale, an all-time low

The Arlo Essential Indoor 2K at $14 is the cheapest real security camera in the sale, an all-time low at 82% off. For the price of lunch you get a 2K indoor cam with a built-in privacy shutter that physically blocks the lens when you’re home. It covers a hallway, a pet area, or a kid’s room, and setup is a few minutes in the Arlo app. At $14, it’s an easy impulse add even if you already have cameras. Buy two and cover the whole floor.

Ring Outdoor Cam (Stick Up Cam) $39.99 (was $79.99)

The easy add for existing Ring users, an all-time low

Ring Outdoor Cam (Stick Up Cam)
Jump into the Ring ecosystem.

The Ring Outdoor Cam at $39.99 is the pick if you’re already in the Ring ecosystem, an all-time low and half off. It ties into the same app as a Ring doorbell, so your alerts and clips all live in one place. The weather-resistant design handles a porch or a side yard, and it works wired or with the quick-release battery pack. A Ring Protect plan adds recorded video. If your doorbell is already a Ring, this is the camera that fits.

Arlo Ultra Security Camera 4K HDR (3rd Gen) $314.00 (was $749.99)

Sharpest footage for serious property coverage, an all-time low

The Arlo Ultra 4K at $314 is the high-end pick for the sharpest footage, an all-time low on Arlo’s top camera. 4K HDR means you can zoom into a recorded clip and still read detail, which matters for a long driveway or a property line. It adds a built-in spotlight, color night vision, and a siren, and it runs on a rechargeable battery. It’s overkill for a hallway, but for serious property coverage it’s the best Arlo makes. It comes with a Secure trial for 4K cloud recording.

Best eufy home security deals

eufy’s cameras, doorbells, and locks store footage locally with no required monthly fee, which is the main reason to pick the brand over Ring or Arlo. Anker’s Prime Day sale cuts a fresh batch, led by the wired PoE NVR S4 Max system at $999.99 and down to the Video Doorbell E340 at $99.99. [TK: link to full Anker Prime Day post]

Best Prime Day outdoor security camera deals

These are the outdoor security cameras, led by the Ring Spotlight Cam Pro Plug-In at $349.99, 34% off. The Tapo 2K+ wired cam at $29.99 is the most affordable pick here.

Best Prime Day video doorbell deals

For video doorbells, the Ring Wired Doorbell Pro at $179.99 is the standout, an all-time low, with options down to the Blink Video Doorbell + Outdoor 4 bundle at $27.99.

Best Prime Day indoor and pet camera deals

The Ring Indoor Cam Plus Plug-In at $69.99 leads the indoor and pet cameras, 56% off, and the Blink Mini 2 Home Security at $12.99 is the budget end.

Best Prime Day smart lock deals

These are the smart locks, led by the Lockly Secure Pro Smart Lock Wi-Fi at $216.99, 32% off. The ULTRALOQ U-Bolt WiFi Smart Lock at $75.97 is the most affordable pick here.

Best Prime Day smart plug, light and thermostat deals

For smart home essentials, the Arlo Home Security System at $186.00 is the standout, an all-time low, with options down to the Amazon Smart Plug Works at $12.99.

More Prime Day smart home deals

The Ring Alarm 14-Piece Kit at $298.97 leads the rest of the smart home deals, 44% off, and the Chamberlain myQ garage camera at $14.99 is the budget end.

Camera prices move through Prime Day, so check the current price before you commit. If you grab one thing, make it the Arlo Essential Pan Tilt at $33, the easiest security upgrade in the sale and cheap enough to buy without overthinking it.
