Short answer: A commercial video surveillance system is a network project as much as a camera purchase. Before comparing camera brands, decide what each camera has to do (see movement, recognize a face, read a plate), how long footage must be kept, where it will be stored, and whether your cabling and switches can power and carry it. Get those four answers right and the camera list gets short.
Start with what each camera has to do
The most common mistake we see on Orlando sites is buying cameras by the box count: “we need sixteen cameras.” Sixteen cameras that can’t identify anyone are sixteen expensive motion detectors. Walk the property instead and give every camera location a job. The front entrance needs to identify faces. The parking lot needs to show which way a vehicle went and, at the gate, maybe read a plate. The warehouse aisle needs to show that someone was there and what they carried.
Writing the job next to each location does two things. It tells you which camera type and lens belongs there, and it gives you a way to judge the system after install: pull a clip from each camera and ask whether it does its job.
Key takeaways
- Give every camera a job (detect, recognize, identify) before choosing hardware.
- Pixels on target, not the megapixel number on the box, decides whether you can identify someone.
- Retention time, codec and frame rate drive storage cost more than camera count.
- Cameras are network devices: plan cabling, PoE budget and network isolation with them.
- In Florida, leave audio recording off unless your attorney has signed off.
Resolution and pixels on target
A 4K camera covering a whole parking lot can still fail to identify a face, because the face only covers a few pixels of a very wide image. The useful measure is pixels on target: how many pixels per meter (or per foot) land on the subject at the distance you care about. The international surveillance standard IEC 62676-4 gives a practical yardstick, often called DORI:
| Job | Pixels per meter on target | What it gets you |
|---|---|---|
| Detect | 25 px/m | Something or someone is there |
| Observe | 62.5 px/m | What they’re doing, clothing, general build |
| Recognize | 125 px/m | Someone who knows the person could recognize them |
| Identify | 250 px/m | Enough detail to identify a stranger |
In practice that means wide cameras for coverage and tighter, closer cameras at choke points such as doors, registers and gates. A good designer will show you the expected pixels-on-target for each critical camera before you sign anything.
Where footage lives: NVR, VMS or cloud
There are three common ways to record and manage cameras, and each fits a different business:
- NVR (network video recorder). A dedicated box on site that records the cameras. Simple and cost-effective for a single location with a modest camera count.
- VMS (video management software). Software running on a server that manages cameras across one or many sites, with stronger search, permissions and integrations. The usual choice once you have multiple buildings or need to tie video to access control.
- Cloud video (VSaaS). Footage is stored or managed in the provider’s cloud, often with a small device on site. Easy remote access and no server to maintain, at the cost of a monthly fee per camera and a dependence on your upload bandwidth.
Many businesses end up with a hybrid: recording happens locally so it keeps working if the internet drops, with remote viewing and selected clips in the cloud. If you want people watching the cameras in real time, our guide to remote video monitoring in Orlando covers how live monitoring fits on top of any of these.
How long to keep footage
Decide retention before you size storage. Thirty days is a common business policy, because many incidents (a slip-and-fall claim, an inventory discrepancy) surface a week or two after they happen. Your insurer, your industry or a lease may ask for longer. Check, don’t guess.
Storage then depends on four things: the number of cameras, resolution, frame rate, and whether you record continuously or on motion. The video codec matters too. H.265 typically needs noticeably less storage than H.264 for similar quality, which can be the difference between one recorder and two. Ask for the storage math in writing, per camera, at your chosen retention.
Cabling, PoE and the network underneath
Modern business cameras are IP devices that take power and data over one Ethernet cable (Power over Ethernet, or PoE). That makes the network part of the camera system:
- Distance. A standard Ethernet run is limited to 100 meters (328 feet). Parking-lot poles and outbuildings beyond that need fiber or an extender.
- PoE budget. Each switch can only supply so much power. PTZ cameras and cameras with heaters or strong IR draw far more than a basic dome, so add up the watts before choosing switches.
- Bandwidth and isolation. Cameras stream around the clock. Put them on their own network segment (VLAN) so they don’t slow your phones and computers, and so a compromised camera can’t reach the rest of your network.
This is why we plan surveillance alongside structured cabling rather than as a separate trade. If you’re building out or moving, the cabling for cameras is far cheaper to run while the ceilings are open.
Built for Florida: sun, heat, storms
Central Florida is hard on outdoor cameras. Look for an IP66 or IP67 weather rating for rain and humidity, and an IK10 impact rating anywhere a camera can be reached. Glass entrances facing the afternoon sun need wide dynamic range (WDR) or the person in the doorway turns into a silhouette. And because Florida sees so much lightning, outdoor runs should have surge protection where the cable enters the building. A single strike can take out a whole switch full of cameras without it.
Locking down the cameras themselves
An internet-connected camera with a default password is an open door into your network. The basics: change every default credential, keep camera and recorder firmware updated, isolate cameras on their own VLAN, and don’t expose recorders directly to the internet for remote viewing. Use the manufacturer’s secure remote access or a VPN instead.
If your business holds or bids on federal contracts, also check brand eligibility. Section 889 of the 2019 National Defense Authorization Act bars federal agencies from buying, or contracting with companies that use, video surveillance equipment from certain manufacturers, including Hikvision and Dahua. “NDAA-compliant” cameras avoid that problem, and some businesses without federal work choose them anyway.
A Florida warning about audio
Many cameras can record sound, and in Florida that deserves caution. Florida law generally requires the consent of everyone in a private conversation before it is recorded, which makes always-on audio in offices, break rooms or customer areas a legal risk. Leave audio off and turn it on only where an attorney has reviewed the use. Video-only recording in areas where people have no expectation of privacy, with clear signage, is the usual safe ground.
The spec checklist
Take this list into any surveillance quote, ours included:
- A camera schedule listing every location, its job (detect, observe, recognize, identify) and the expected pixels-on-target.
- The recording platform (NVR, VMS, cloud or hybrid) and why it fits your sites.
- Retention in days, with the storage calculation per camera.
- Cable routes, run lengths, and anything over 100 meters called out with the fiber or extender plan.
- Switch models and the total PoE budget, with headroom.
- Weather and impact ratings for outdoor cameras, plus surge protection on outdoor runs.
- The network plan: camera VLAN, how remote viewing is secured, who holds the admin credentials.
- Whether cameras are NDAA-compliant, if that matters to your contracts.
- Audio: off, or documented approval for where it’s on.
- Who services the system, and how firmware updates are handled after install.

Frequently asked questions
How many security cameras does a small business need?
There’s no fixed number. Count the entrances and exits, the cash or inventory points, the parking areas and any blind corners, then give each one a job: detect, observe, recognize or identify. A small office might need four to six cameras, while a warehouse with a yard needs many more. The job list sets the count, not a package size.
Can we keep our existing analog cameras?
Often for a while, yes. Hybrid recorders and encoders can bring working analog cameras into a newer IP system, which spreads the cost of an upgrade over time. New camera locations should be IP, and analog cameras covering critical spots like entrances are usually the first worth replacing.
Do we need cloud storage for our cameras?
No. Recording locally on an NVR or VMS server works well and keeps recording if the internet goes down, and you can still view cameras remotely. Cloud storage adds an off-site copy and easier multi-site access, in exchange for a monthly fee and more upload bandwidth.
How long should a business keep surveillance footage?
Thirty days is a common policy because many incidents surface a week or more after they happen. Your insurer, industry rules or a lease may require longer, so confirm before you size storage.
Is it legal for security cameras to record audio in Florida?
Florida generally requires the consent of everyone in a private conversation before it can be recorded, so always-on audio carries legal risk. The safe default is video only, with audio enabled only where an attorney has reviewed the use.
