  • Tesla’s Sentry Mode and Dashcam Are Built In. The Storage Is Not.

    Tesla’s Sentry Mode and Dashcam Are Built In. The Storage Is Not.

    Sentry Mode and Dashcam are software features included on every Tesla at no extra cost. Neither requires a subscription. What they do require is a piece of hardware you supply yourself: a USB flash drive plugged into the car’s USB port.

    What each feature actually records

    Dashcam records video from the car’s exterior cameras while you drive. Per Tesla’s owner’s manual, it works in three ways: it saves automatically when the car “detects a safety-critical event, such as a collision or airbag deployment,” it saves the most recent ten minutes when you tap the Dashcam icon on the touchscreen, and it saves the most recent ten minutes when you press the horn. Sentry Mode is the parked-car alarm. According to Tesla’s manual, it activates “if a threat is detected or the vehicle sensors determine there is a lot of jerky movement, like when getting towed or shaken,” then records using the car’s cameras and sensors while the alarm and lights activate. Rear-camera recording is only available on cars “manufactured after approximately February 2018.” Recordings stay on your drive and are not uploaded to Tesla, per the same manual.

    The USB drive Tesla requires

    Tesla’s USB drive requirements page spells out the minimum hardware: a drive with at least 64 GB of storage and “a sustained write speed of at least 4 MB/s.” The drive needs to be USB 2.0 compatible; if it’s USB 3.0, it must also support USB 2.0. You format it in the car itself by touching Controls > Safety > Format USB Drive, which formats the drive as exFAT (or MS-DOS FAT for Mac, ext3, or ext4 — NTFS is not supported) and creates a TeslaCam folder with three subfolders: RecentClips, which Tesla says “contains up to 60 minutes of recorded content,” SavedClips for anything you’ve manually saved, and SentryClips for security events. You can use one drive for Dashcam, Sentry Mode, and music, but Tesla says you need separate partitions or folders on it. Some cars “manufactured beginning approximately 2020” ship with a pre-formatted drive already in the glovebox, per the same manual — everything else, you’re supplying and formatting yourself.

    Why footage disappears, and when to consider more storage

    Because the buffer is a rolling loop, older footage gets erased to make room for new footage unless you save it. Tesla’s own guidance states it plainly: “Footage is continuously overwritten unless you save it,” and how much of a backlog you get before that happens depends heavily on the drive itself — Tesla says retention runs “as low as 1 hour” on smaller drives and “up to 24 hours” on larger drives of “1 TB or more.” A drive that’s too small, or too slow to sustain that 4 MB/s write speed, can also cause dropped or corrupted clips. This is the practical reason owners upgrade: if you’ve had Sentry Mode overwrite an incident before you could save it, or you just want a full day of rolling Dashcam footage instead of an hour, the fix is a larger-capacity or faster-rated USB drive. Some owners also move to a dedicated multi-port USB storage accessory built for dash cam use, which can make it easier to keep a drive permanently installed and organized without swapping a single flash drive in and out. Whichever route you take, stick to Tesla’s minimum capacity, speed, and file-system requirements above, since a drive that falls short of them may fail to record reliably.

    Separately, Sentry Mode itself stays active until the car’s battery drops to 20% or below, unless you’re parked at a Supercharger, according to Tesla’s vehicle safety and security page. That same page describes a Live Camera feature that lets you view your car’s surroundings remotely while parked; it requires Premium Connectivity and Tesla app version 4.2.1 or later, is described by Tesla as “end-to-end encrypted and cannot be accessed by us,” and isn’t available on 2012-2020 Model S and Model X.

  • Leasing vs. Buying a Tesla: Which Costs Less in 2026

    Leasing vs. Buying a Tesla: Which Costs Less in 2026

    The math on leasing versus buying a Tesla changed in 2025, and it changed for both sides. The federal Section 30D clean vehicle tax credit, worth up to $7,500, is not available for any vehicle acquired after September 30, 2025 — and the same IRS page confirms the commercial clean vehicle credit that leasing companies used to claim on your behalf ended on that same date. Before the cutoff, leasing sometimes had an edge because Tesla’s finance arm could claim a commercial credit with looser rules than the consumer credit and build some of the savings into your monthly payment. That advantage is gone now, so the tax credit no longer tips the scale toward either option. None of this is financial advice — it’s a rundown of how each option works today so you can weigh the tradeoffs yourself.

    How a Tesla lease works now

    When you configure a Tesla for lease, you choose your down payment, lease term, and annual mileage directly in Tesla’s ordering tool, and it generates an estimated monthly payment based on those choices. Lease approvals require a credit check and are only valid for 60 days. According to Tesla’s own comparison of financing and leasing, leases run 24 to 36 months, shorter than the 36-to-84-month range available on loans. You need a Social Security number and to be at least 18, and leasing is not offered everywhere.

    What happens at the end of a Tesla lease

    One common assumption is worth correcting: Tesla does let you buy your leased car. Its lease-end options page states that U.S. vehicles leased through Tesla Lease Trust “may be eligible for purchase” (Iowa and Louisiana are excluded), for a purchase fee of up to $350 plus local taxes. Your other choices at lease-end are to return the car after a final inspection, trade it in for a new Tesla, which can come with loyalty incentives, or extend the same lease once for up to six months. If you want out early, Tesla’s early termination policy lets you settle up through the app, but Tesla says directly that ending a lease early “can be costly” — the payoff depends on your remaining balance, the car’s current market value, and where you live, and quotes expire the day before your next payment is due.

    How financing works

    Buying with a loan means signing a Retail Installment Contract before delivery, whether you finance through Tesla or a third-party lender, and committing to a longer repayment window of up to 84 months. You own the car once the loan is paid off, with no mileage cap and nothing to hand back for inspection. Paying cash skips financing entirely and gives you full ownership from day one, though it ties up more money upfront.

    Why the tax credit is no longer the deciding factor

    For most of 2025, leasing a Tesla could work out cheaper partly because the tax credit flowed through the lease rather than to a buyer directly. That gap closed fast: Kelley Blue Book reported that Tesla raised Model Y lease payments by as much as $70 a month and Model 3 lease payments by as much as $80 a month right after the credit expired on September 30, 2025, as it rebuilt the lost incentive into sticker lease pricing. The credit no longer separates leasing from buying financially — it is off the table either way.

    Questions to ask yourself

    Leasing tends to suit you if you want a newer Tesla every few years, drive a predictable and moderate number of miles, and would rather not think about resale value or long-term battery health. Buying tends to suit you if you plan to keep the car past the length of a typical lease, drive more miles than a lease allowance comfortably covers, or want to build equity you can eventually sell, trade, or drive payment-free. Before deciding, ask yourself: How many years do you realistically keep a car? How many miles do you drive a year, and does that fit inside a lease’s mileage limit without triggering per-mile overage charges at return? Do you want to own this vehicle outright someday, or would you rather hand the depreciation risk back to Tesla every few years? None of this is a recommendation — it’s the shape of the tradeoff so you can run your own numbers.
