How Long Should You Keep Security Camera Footage? Retention Rules of Thumb for Central Florida Businesses and Homes

It is one of the most common questions we hear after a camera install, and usually it comes up at the worst possible moment: a customer calls about a slip and fall from three weeks ago, or a missing deposit finally shows up on the books, and the owner asks, “how long should you keep security camera footage?” If the recorder already overwrote it, the honest answer is “longer than you did.” The good news is that picking a sensible retention window is not complicated, and the storage to support it costs far less than it did even a few years ago.

This guide walks through the retention periods we recommend, what Florida actually requires, how to size your storage, and the mistakes that quietly erase the one clip you needed. We design and install camera systems for businesses and homeowners across Orlando, Lake County, Clermont, Mount Dora, Eustis, Tavares, Leesburg, and Apopka, so the numbers below reflect what works for real Central Florida properties, not a national average.

1. The short answer: 30 days for most businesses, 7 to 14 days for most homes

For a typical small business (retail, restaurant, office, warehouse, medical or dental practice) we recommend keeping at least 30 days of continuous footage. For a home, 7 to 14 days covers nearly every real-world situation: a package theft, a car break-in, a contractor dispute, or an insurance claim after storm damage. If your home doubles as a short-term rental, treat it like a business and go to 30 days. These are floors, not ceilings. If the storage is cheap enough to hold 60 or 90 days, there is rarely a reason not to.

2. Why 30 days is the sweet spot for a business

The incidents that cost small businesses the most money are almost never discovered the same day. A slip-and-fall claim often arrives as a letter from an attorney two or three weeks after the visit. A credit card chargeback can be filed 60 to 120 days after the sale, but the dispute notice usually reaches you within the first month. Inventory shrink shows up at the end of a counting cycle. Employee time-clock disputes surface when the paycheck lands. A 30-day window catches the overwhelming majority of these, and when you need to go back further, the next section explains how to hold footage past the normal rotation.

3. What Florida law actually requires

Here is the part most guides get wrong: Florida has no general law telling an ordinary business how long to keep security camera footage. Retention is a business decision for most owners. The exceptions are regulated industries. Licensed medical marijuana treatment centers, for example, must keep surveillance recordings for at least 45 days under state rules, and pharmacies, financial institutions, and childcare facilities often carry retention requirements from their own regulators or licensing boards. Your insurance policy may also set an expectation, so read the fine print. The one rule that applies to everyone: once you know about an incident that could become a lawsuit or a claim, you have a duty to preserve the relevant footage. Letting the recorder overwrite it after you were put on notice can be treated as destroying evidence, and that goes badly in court. When in doubt, export the clip and keep it.

4. The storage math, in plain English

Retention is really a storage question. A modern 4-megapixel camera recording around the clock with H.265 compression uses roughly 15 to 25 GB per day depending on scene activity and frame rate. Eight of those cameras recording continuously for 30 days land somewhere around 4 to 6 TB. Switching to motion-triggered or smart-event recording typically cuts that by half or more, because an empty parking lot at 3 a.m. does not need to be written to disk. A network video recorder (NVR) with 8 to 12 TB of purpose-built surveillance drives is a modest line item today, and it comfortably delivers 30 to 60 days for a small business. If you are planning a new system, our breakdown of PoE versus wireless cameras covers why wired cameras make continuous recording far more reliable.

5. Local recorder, cloud, or both?

A local NVR is the workhorse: it records everything, it does not depend on your internet connection, and there is no monthly fee per camera. Cloud-only cameras are convenient for a front door or a single office, but the subscription math gets ugly fast with eight or sixteen cameras, and most consumer cloud plans only keep 30 to 60 days of event clips, not continuous video. The setup we recommend for most Central Florida businesses is a hybrid: the NVR holds 30 or more days of continuous footage on site, and important clips (or a nightly copy of key cameras) are pushed to cloud storage so a burglary, fire, or hurricane that takes out the recorder does not take the evidence with it. That is the same off-site logic we apply to business data backups, and for good reason.

6. When you need to keep footage longer

Every decent recorder lets you lock or protect a time range so it survives the normal overwrite cycle, and every one lets you export a clip to a USB drive or a network share. The moment something happens, do both: lock the segment on the NVR and export a copy with the original time stamps intact. Name the file with the date, the camera, and a one-line description, store it somewhere backed up, and keep it for as long as the matter could be live, which for a Florida negligence claim can be years. If the police or an attorney ask for footage, give them a copy and keep your original. A clip you no longer have is a story you can no longer prove.

7. The mistakes that erase the footage you needed

Retention settings are only half the battle. The failures we see most often in the field are painfully ordinary: a hard drive that died six months ago and nobody noticed because the live view still worked; a recorder that was never set to the correct time zone, so the “footage from Tuesday at 2 p.m.” is actually from Tuesday at 6 p.m.; cameras knocked out of alignment by a storm or a delivery truck; and recorders still running the factory default password, which is how the “can security cameras be hacked” headlines happen. A quarterly check that the system is recording, the clock is right, and the firmware and passwords are current takes twenty minutes and is the single best thing you can do to protect your investment. It is included in our security camera service plans precisely because almost nobody remembers to do it.

The Bottom Line

Keep at least 30 days of footage for a business and 7 to 14 days for a home, more if your industry, insurer, or rental situation calls for it. Size the recorder for the window you want with room to grow, use motion recording where it makes sense, keep a cloud or off-site copy of anything important, and lock and export clips the moment an incident occurs. Most of all, check that the system is actually recording before you need it. Retention is cheap insurance, and it only pays out if the footage is still there.
