There are hundreds of home security cameras on the market, ranging drastically in price, functionality and quality. With all the options, it can be hard to not become overwhelmed fast, especially when you’re considering something as important as your home’s safety. After CNET’s years of testing home security cameras, I have some tips if you’re on the hunt for a new one. Here are a few parameters to consider:

Privacy

This is a big one. You don’t want anyone peeping on your property or hacking into your camera. Wireless home security cameras can be more susceptible to hacking due to their connectivity to Wi-Fi networks and remote access, especially if you have poor router security. Wired home security cameras that don’t use Wi-Fi at all are generally more secure. (Read more about the pros and cons of wired vs. wireless systems here.) As I mentioned above, data breaches and security vulnerabilities can also be dangerous for your privacy, so it’s important to consider a company’s recent reputation.

Indoor vs. outdoor

One of the first things you’ll need to consider is where you want to place your home security cameras. If you want your camera to be located outside, recording your porch or yard, you’ll likely want an outdoor camera that’s also weather-resistant or features night vision. 

While many cameras can be used interchangeably for indoor or outdoor purposes, some cameras are solely made for indoor usage, so make sure you’re buying cameras that can handle the outdoor elements. 

Video resolution

Video quality should be a major consideration when buying a home security camera. In simplest terms, your camera won’t be effective if the only footage being recorded is grainy and unreadable. 

The higher the resolution, the better the video quality. Most home security cameras on the market now have 1,080p resolution, but others have 2K resolution (like the Arlo Pro 4) or 1,536×1,536-pixel resolution (like the Arlo Video Doorbell), and a growing number have embraced 4K. Just remember, the higher the video quality, the more bandwidth it takes up and the more likely your camera is to experience lag times or glitches. 

Field of view

Field of view (usually provided diagonally) refers to how broad the camera’s view is. Broader is generally better because it captures more space and makes it easier to spot activity. The average security camera tends to top out around 130 degrees, although some go beyond that. Pan and tilt features make the field of view less important since the camera can move around.

I find a broad field of view is great if you want to survey multiple corners of a backyard — less important if you just want to keep eyes on packages and guests right in front of your door.

Battery or wired power

Battery and wireless cameras versus wired options are a matter of taste since both types have pros and cons. 

Wireless options are usually easier to install and operate, and often use cloud storage, so you can access your footage from anywhere. Wireless security cameras have their own power supply, so even during an internet or power outage, they can still record and save footage. One of the biggest disadvantages is that you’ll need to manually change the batteries or charge them every so often unless you get a solar-powered home security camera.

Wired cameras are hardwired to a steady connection, so they don’t need to be recharged and can often boost a high-quality video resolution. They tend to be more reliable, secure and consistent in video quality while not requiring monthly cloud storage fees. However, not all owners will feel comfortable wiring in a camera without a pro’s help, and they’re not great options for renters and people living in apartments.

Local vs. cloud storage

Not all video storage is equal. You have two main options and picking one is up to your personal preference. There’s cloud storage, which sends your video footage to a remote server to be saved, and local storage, which relies on a separate accessory or piece of hardware, usually a microSD card, to hold any footage you’d like to save. Usually, cloud storage requires a monthly fee of around $5 to $10.

Wi-Fi quality and range

When you’re installing wireless home security cameras, keep in mind that the smart home camera you buy (and your security system as a whole) will only be as good as the quality of your Wi-Fi connection at the location where you plan to install it. So check your Wi-Fi speed before you drill holes in the walls or otherwise mess up your door frame, brick or siding for your home security camera. If the connection is spotty on your wireless security camera, you’ll notice significant lag times, pixelation in the live feed and other Wi-Fi delays. These make the video quality poor and home security cameras a pain to use.

With a good Wi-Fi connection, you should be in good shape to use your indoor home security camera or outdoor home security camera without any major camera system issues and get clear footage every time. Still have questions? Take a look at my home security camera buying guide and the below FAQs.

A stable frequency source is a fundamental requirement in virtually every RF and wireless system, yet all real-world oscillators exhibit some degree of short-term frequency instability known as phase noise. This instability manifests as unwanted sidebands around the carrier in the frequency domain and as timing jitter in the time domain. When phase noise is excessive, it causes spectral regrowth that leaks energy into adjacent channels, reduces receiver sensitivity through reciprocal mixing, and rotates digital modulation constellations to the point where bit errors multiply. Understanding these effects is essential for engineers designing transmitters, receivers, and frequency synthesizers for modern communications standards. This guide walks through the physics of phase noise, its practical consequences for system performance, and the two principal measurement approaches — the traditional spectrum analyzer method and the more sensitive cross-correlation technique used in dedicated phase noise analyzers — giving engineers the knowledge they need to specify, measure, and minimize phase noise in their designs.

Ahead of the closure of the unionized Apple Towson Town Center in Maryland, protesting workers have called out Apple for allegedly treating them worse than workers from other closing stores.

Towson was the first Apple Store to unionize, and that may or may not have been a factor in Apple including it in a trio of stores to be closed down. But what is certain is that Apple is treating this store’s employees differently from the others, and that is why there was a public rally on May 27, 2026.

According to Baltimore NBC affiliate WBAL, employees, local elected officials, and leaders of the International Association of Machinists and Aerospace Workers (IAM) Union, led the protest outside the County Courthouse.

In all, Apple is closing three stores, citing declining retail conditions in the malls they are in. As well as Towson, the stores are Apple North County, in Escondido, California, and Apple Trumbull in Trumbull, Connecticut. Employees at the two non-union locations are automatically being offered transfers to other stores.

Towson staff, however, are not, and must apply for positions in other Apple Stores. Apple says that this is down to the terms of the contract negotiated with unions, which mandates severance on the closure of a store.

“Apple offers severance to all of their employees, not just what we negotiate,” Apple store worker Eric Brown told reporters. “So to say that it’s based on the severance is just false.”

Brown was the main employee who spoke at the rally, but he was joined by council members, and also representatives of the union. “[This] is retaliation plain and simple,” said IAM International President Brian Bryant. “Shame on you, Apple.”

Apple’s union-busting record

Apple has previously been accused of illegal anti-union practices, and head of retail Deirdre O’Brien has spoken out against unionization. She’s said that the relation between Apple and its store staff could be “fundamentally changed” if they unionize.

“And I worry about what it would mean to put another organization in the middle of our relationship,” she continued. “An organization that doesn’t have a deep understanding of Apple or our business, and most importantly, one that I do not believe shares our commitment to you.”

O’Brien took over as head of retail and people for Apple in 2019. “Deirdre deeply understands Apple’s unique culture and that people join Apple to do the best work of their lives,” said Tim Cook at the time. “She is a superb leader and I’m thrilled she will be bringing her experience and talent to this critical role.”

Yet for all that the role is critical, and especially all that O’Brien says about Apple’s commitment to its staff, in practice employees have been driven to unionize.

In 2022, it was the same Eric Brown who now spoke at the rally, who summarized the real relationship between Apple and its staff. “It’s like writing a letter to Santa,” he said. “Pretty much just like an empty slot that leads to a fire pit.”

Apple has said that “we strongly disagree” with the claims of discrimination. However, Apple has reportedly not responded to an open letter from local elected officials.

In hot summer afternoons like these, the speaker you bring to your friend’s barbeque either makes the mood or kills it. The Bose SoundLinkFlex 2 does the former – its compact enough to carry, with the sound quality to back it up, and IP67 waterproofing for whatever the afternoon throws at it.
