If you want to add security cameras around your home without running power cables through walls, the Blink Outdoor 4 2-Camera System is an interesting option. The particular Amazon listing for the product reviewed here is the Like-New version, meaning the cameras have been tested and certified to look and function like new rather than being sold as brand-new retail units.
For anyone looking for an affordable way to monitor an entrance, backyard, driveway, garage or other outdoor area, this system offers a combination of wireless installation, HD video, motion detection and smartphone access that makes it relatively easy to get started.
The package includes two Blink Outdoor 4 cameras, a Sync Module 2, four AA lithium batteries, two mounting kits, a USB cable and a power adapter. The cameras can be monitored through the Blink app, while the Sync Module helps connect the cameras to your network and provides an option for local storage when paired with a compatible USB drive.
Completely Wire-Free Installation
The biggest attraction of the Blink Outdoor 4 is its wire-free design.
Each camera runs on two AA lithium batteries, meaning you don't need to install a power outlet next to the camera or run a long power cable from inside your house. Blink advertises battery life of up to two years under its default conditions, although actual battery life will depend on settings, usage and environmental conditions.
This makes the cameras particularly useful for locations where running electrical wiring would be inconvenient or expensive.
For example, one camera could be mounted above the front entrance while the second monitors the backyard or driveway. Because you're not tied to a power socket, you have considerably more flexibility when deciding where to position them.
Installation is also designed for ordinary users rather than professional installers. The included mounting kits allow the cameras to be attached to suitable surfaces, after which the system can be configured using the Blink app.
1080p HD Video and Night Vision
The Outdoor 4 provides 1080p HD live video, along with infrared night vision. This gives you the ability to check what's happening around your property during both daytime and nighttime.
The camera has a 143-degree diagonal field of view, which provides reasonably broad coverage for a small camera. It can also capture video at up to 30 frames per second under supported conditions.
Naturally, expectations should be realistic. This isn't a professional surveillance camera designed to provide highly detailed identification from a long distance. It's better viewed as a convenient home-monitoring camera.
For watching an entrance, walkway, patio, driveway or backyard, 1080p is generally enough to see what's happening. The infrared night vision is particularly useful because the camera doesn't become useless once the sun goes down.
One thing worth remembering is camera placement. Blink itself notes that its cameras aren't designed to work correctly when viewing through glass, and motion detection and nighttime image quality can be affected in that situation.
Motion Detection
Motion detection is one of the most important features of a security camera, and the Outdoor 4 includes enhanced motion detection with customizable detection zones.
Blink says its motion detection works best when subjects are roughly 7 to 19 feet from the camera, while motion can be detected at distances of up to about 30 feet depending on circumstances. Placement, temperature and the size of the moving object can all affect detection performance.
The ability to customize motion zones is useful because you don't necessarily want an alert every time something moves in the background.
For example, if your camera faces a road, you could configure the detection area to concentrate more heavily on your driveway or entrance instead of constantly reacting to passing traffic.
That said, motion detection isn't perfect. Real-world user experiences can vary significantly depending on placement and environmental conditions. Some Blink owners have reported frustration with false alerts or missed motion, so it is worth spending some time adjusting the camera position and detection settings rather than expecting perfect results immediately.
Two-Way Audio Is Surprisingly Useful
Another useful feature is two-way audio.
The camera has a microphone and speaker, allowing you to communicate with someone near the camera through the Blink app. This means you can see and speak to someone without physically being at the location.
It can be useful for several situations. You could tell a delivery driver where to leave a package, speak to a family member outside, or warn an unexpected visitor that the property is being monitored.
It's not a replacement for an intercom system, but having two-way communication built into a small wireless camera is convenient.
The Sync Module 2 Adds More Flexibility
The included Sync Module 2 is an important part of this particular package.
One of its advantages is that it provides the option of local video storage when combined with a compatible USB drive. You can also use Blink's cloud storage options depending on the subscription plan you choose.
This is worth paying attention to because cloud subscriptions can change the long-term cost of a security camera system.
The ability to use local storage gives users another option instead of relying entirely on cloud storage. However, the USB storage device is not included with this particular package, so you'll need to purchase one separately if you want to take advantage of local storage.
The cameras can also work with Alexa, allowing supported Alexa devices to display the camera feed and provide hands-free interaction.
What Does "Like-New" Actually Mean?
This is probably the most important consideration when looking at this particular Amazon listing.
You're not buying the standard brand-new retail package. The listing is for an Amazon Like-New product.
According to the product information, Like-New Blink Outdoor 4 units are tested and certified to look and function like new. They may have minor cosmetic imperfections and may be packaged in generic Amazon-branded packaging rather than the original retail box. The listing also states that the Like-New version receives the same limited warranty as a new device.
For someone who doesn't care about having a factory-sealed box, this can be a good way to get the hardware for less money.
In fact, historical deal tracking has shown the Like-New two-camera package selling substantially below its typical new price, making the refurbished option particularly interesting when discounted.
The important thing is to compare the actual Like-New price with the current price of a new Outdoor 4 system. If the difference is only a few dollars, buying new may make more sense. If the discount is substantial, the Like-New version becomes much more attractive.
Battery Life: Excellent on Paper
The advertised battery life of up to two years is one of the strongest selling points.
Because the cameras use standard AA lithium batteries, you aren't constantly looking for an outlet or charging the cameras every few weeks.
However, two years should be viewed as an estimate rather than a guarantee. Frequent live viewing, frequent motion events, environmental conditions and camera settings can all affect battery consumption.
If the camera is installed somewhere with heavy activity, it may use considerably more battery than a camera that only detects a handful of events each day.
The Subscription Question
The Blink system is attractive because of its relatively simple hardware, but buyers should understand the storage model before purchasing.
Blink offers cloud storage through its subscription plans, while the Sync Module 2 provides a local-storage option when paired with a USB drive. Some advanced functions, including person detection on the Outdoor 4, are associated with an optional Blink subscription plan.
This doesn't make the cameras a bad purchase, but it does mean you should consider the total cost rather than looking only at the camera price.
If you simply want occasional live viewing and basic security monitoring, you may not need every subscription feature. If you want extensive cloud recording, person detection and other advanced functions, the subscription becomes more relevant.

Final Verdict
The Blink Outdoor 4 Like-New 2-Camera System is a practical choice for someone who wants basic outdoor security without the hassle of running power cables.
Its biggest strengths are the wire-free installation, two-year advertised battery life, 1080p video, infrared night vision, two-way audio and smartphone access. The included Sync Module 2 is also a useful addition because it gives you the option of local storage rather than forcing you to depend entirely on cloud storage.
The fact that this particular package is sold as Like-New is both its biggest potential advantage and something buyers need to consider carefully. If the discount compared with a brand-new system is significant, it can be a very good value. If the price difference is small, buying new may be worth considering.
Overall, I would recommend the system for homeowners, renters and small businesses looking for an affordable way to monitor two areas without installing wired cameras.
Overall rating: 4.5/5
Best for: Homeowners and renters who want simple, wire-free outdoor security.
Best features: Wireless installation, battery life, 1080p video, night vision, two-way audio and smartphone monitoring.
Main drawback: Some of the more advanced security and storage features can involve additional costs.
If you're specifically looking at this product because the Like-New price on Amazon is much lower than the new version, it's one of those products where the discount can make a big difference in whether it's a good buy.
