Not sure how to make up your mind? Here are the most important factors when considering a home security system that will spare your wallet.
Pricing and subscriptions
Security systems can be opaque when it comes to final pricing. The listed cost is often replaced by constant, rotating discounts which are more representative of the actual cost, and total subscription fees may not be obvious.
For our list, we chose DIY companies with upfront pricing models so you can see what you get, aiming generally between $200 and $300. If you want to save as much as possible, watch subscriptions carefully to see what’s included. Sometimes, you may be able to get away without a subscription at all, especially if you don’t want any cameras. Other times, a basic self-monitoring plan may be required.
App controls
Apps should be easy to understand and avoid hiding important features behind complex menus or constant demands for subscription fees. Look for clean apps with helpful user interfaces, large touchscreen buttons and walkthroughs during your setup process.
Setup and installation
Avoiding professional installation is a great way to save money, so we chose systems that are DIY and don’t have any contract requirements.
Installation also affects value, because smaller, cheaper kits work best when you use them well. That means choosing the most vulnerable doors and windows in your home with as few sensors as possible. You may want to check out our guide on how burglars choose homes to break into.

Flexible arming and disarming
Look for systems that have remote arming and disarming, customizable arming delays to get out the door and similar features. Automatic arming and disarming based on time of day, geofencing and other options are also handy.
Movability
Affordable security systems are great fits for rentals and apartments, but what happens when you have to move? We favored systems that use adhesive rather than leaving holes in the wall, and that are relatively easy to take down, pack up and install again during a move.
Additional features
Take a look at add-ons if you ever want to expand your system. Look for a variety of sensor options, including motion sensors, video doorbells, fobs, smart locks, glass break/vibration sensors and more. These should be affordable and easy to add.

Smart home compatibility
If you already use a voice assistant or standalone smart home devices, check to see if the home security system supports them before you buy. Google and Alexa are commonly supported, but other platforms less so, and home security systems can vary a lot. Matter compatibility is helping out here, but still has a long way to roll out.
Monitoring options
Even cheap home security systems offer professional monitoring services that can call the police or fire department for you, among other services. But they cost a monthly fee, which kind of defeats the purpose of finding a cheap home security system. If you want a monitoring plan to enable extra features and get professional eyes on your home, they typically cost between $20 to $30 a month for starter versions.
In Cody v. Jill Acquisition LLC, No. 25-937 (S.D. Cal. June 30, 2025), the Southern District of California declined to enforce a retail site’s terms of use and compel arbitration, holding that the plaintiff, who used guest checkout to place an online order at the retail clothing site, did not have adequate notice of the terms and the arbitration clause. This case should serve as a wake-up call for online entities to reexamine electronic contracting processes. It exemplifies how, even if a website’s visual design and its placement of the hyperlinked Terms of Use during user checkout are comparable to other presentations that have been deemed enforceable, a court could still decline to enforce online terms if the context of the transaction is not the typical e-commerce transaction between a registered customer and a retail site. In this case, the court found that by checking out as a guest without creating an account, the user was less likely to expect a continuing relationship and, therefore, the site’s notice and presentation of the terms below the “Place Order” button were not conspicuous enough in this instance to bind the plaintiff.
The plaintiff in Cody filed a putative class action complaint over the site’s pricing policies for alleged violations of the California Business and Professions Code and the Consumer Legal Remedies Act. The defendant moved to compel arbitration, arguing the plaintiff had agreed to the site’s terms of use that contained a “Binding Arbitration Agreement and Class Action Waiver” when plaintiff clicked the “Place Order” button and completed her purchase from the defendant’s website.
Generally speaking, a contract will be enforceable based on an inquiry notice if: (1) the website provides reasonably conspicuous notice of the terms; and (2) the consumer takes some action, such as clicking a button, that unambiguously manifests assent to those terms. When evaluating whether there was an agreement to arbitrate, the court in Cody first considered the visual design of the webpages and found that the visual aspect of the notice was satisfied by the defendant’s website layout. As the court stated, the relevant criteria for evaluating whether the visual elements provide conspicuous notice are whether the advisal is displayed prominently enough that the court can assume a reasonably prudent Internet user would have seen it. Elements such as a “clear and legible” notice on the order page and a hyperlink placed directly above or below an action button formatted in bright, contrasting color and readable font within a relatively uncluttered web page have been favorably cited by courts in past cases.
The court here found the visual design to be adequate because of factors such as the underlined blue hyperlink to the terms of use and its location directly below the “Place Order” button. [See below image from the court opinion of the final contracting screen ].
Although the court recognized that the “design of the website alone might support concluding that the notice would be reasonably conspicuous,” it went on to consider the full context of the guest checkout transaction at issue in Cody. Here, the court distinguished it from those types of transactions where a user might anticipate “some sort of continuing relationship.” The court emphasized that when considering the notice requirement, the visual design of the website must be examined within that context. As it stated: “This means that courts should expect that a reasonable internet user is more vigilant in looking for contractual terms when the context of the transaction reasonably implies a contractual relationship.” To the court, when a user “simply purchases goods or avails herself of a one-time discount offer,” there is less reason for her to expect a continued relationship beyond the purchase.
In the case at hand, the court considered plaintiff’s decision to check out as a guest as one where the user did not anticipate a continuing relationship, and compared it with other traditional e-commerce transactions involving registered users where the Ninth Circuit previously found that such context would put a user on inquiry notice that a purchase on the company’s website constituted an agreement to its terms.
“Generally speaking, courts are more likely to conclude that a user anticipating ‘some sort of continuing relationship’ would expect to be bound by terms, whereas a user ‘who simply purchases goods or avails herself of a one-time discount offer’ would be less likely to form such an expectation.”
“This context distinguishes this case from those in which the Ninth Circuit has found that the context of the transaction would put a user on inquiry notice that use of a company’s website or services constituted an agreement to its terms and conditions, including an arbitration provision.”
Thus, despite the adequacy of its visual aspects on the J. Jill site, the court found that proper notice was not sufficiently conspicuous in this case because of the guest checkout context of the transaction (“The context of the transaction therefore weighs against concluding that Plaintiff was sufficiently aware that, by placing an order through jjill.com, she would be entering into an agreement including an arbitration provision”).
In another recent case, Chabolla v. ClassPass, Inc., 129 F.3d 1147 (9th Cir. 2025), the Ninth Circuit affirmed a lower court’s ruling that declined to send a proposed class action to arbitration. In the ClassPass case, the plaintiff signed up for a trial period for ClassPass, a service that sells subscription packages for access to various gyms and fitness studios, but later took issue when subscription charges resumed after gyms reopened following the COVID-19 pandemic. The contracting process in this case involved several signup screens. [An image from the court opinion of the final screen appears below].
In this case, the court’s decision was a flip, of sorts, of the Cody case, with the Ninth Circuit finding the visual presentation of the terms lacking, even though the context of the transaction would seemingly put the user on notice of an ongoing relationship that would contemplate the user agreeing to site terms. The appeals court found that while a trial subscription opportunity may not indicate an anticipation of an ongoing relationship in all instances, the context neither weighs in favor of nor against the notice requirement. This is because, as the court noted, the other aspects of the context – such as how the purchase is described as a “plan” or a “membership” and how the benefit of ClassPass is to gain access to gyms and fitness studios – conjure the idea of a continuing relationship. Nonetheless, the court ultimately decided that a reasonably prudent internet user would not be deemed to have unambiguously manifested assent to the terms by working her way through ClassPass’s multi-page website checkout process.
Taken together, these two recent decisions show that courts – at least those within the Ninth Circuit – are considering the actual context in which these internet transactions occur when deciding whether an online entity’s contracting and checkout process binds the user to the terms. While visual presentation and web flow design remains important for e-commerce sites, the above two court decisions show that context also matters.
We have previously highlighted the importance of web design in determining if a service’s terms are deemed enforceable. Now, companies might take a second look at their own user registration and e-commerce purchase processes to ensure they offer reasonably conspicuous notice of the existence of contract terms and obtain the user’s manifestation of assent to those terms in all contexts and types of transactions, including those transactions where guest or expedited checkout is used.
Contexts that indicate transient relationships, such as guest checkout or a trial opportunity, may mean that even an ordinary presentation of terms in the form of a hyperlink to the terms located beneath a “Place Order” button – a presentation that is used regularly by many sites – might need to be bolstered, in some cases, to provide the user additional notice that he or she is entering into a transaction that mandates acceptance of contractual terms. As the Cody court commented: “[T]he onus must be on website owners to put users on notice of the terms to which they wish to bind consumers.” Ultimately, the above court decisions accentuate the need for counsel to be involved in the decisions underlying the design and wording of online contracting processes and presentation of terms so entities can attain adequate user notice and assent that would satisfy even the most exacting scrutiny for any type of transaction.
