What analytics can do
| Feature | What it does | Privacy risk |
|---|---|---|
| Person and vehicle detection | Alerts only when a person or car appears, not for moving trees and headlights | Low |
| Smart search | Find footage by attribute, such as a red truck or a person in a blue jacket, across cameras | Low to medium |
| Line crossing and loitering | Alerts for a fence line, a loading dock after hours, a lingering visitor | Low |
| People counting and occupancy | Footfall and dwell time for retail and space planning | Low if counts only |
| License plate recognition | Logs plates at gates and lots | Medium: check state rules on plate data |
| Face recognition | Matches faces against a list of people | High: biometric laws apply |
For most small businesses the first three rows deliver nearly all the value. Person and vehicle detection alone cuts false alerts sharply, and smart search turns an afternoon of scrubbing footage into a few minutes.
Adding analytics to cameras you already have
Analytics can run in three places, and the choice decides whether you need new cameras:
- On the camera. Newer IP cameras include detection on board. Nothing extra to buy, but older cameras cannot be upgraded this way.
- On the recorder or an analytics appliance. An AI-capable network video recorder or a small appliance processes streams from existing IP cameras, often from other brands through the ONVIF standard. The usual route for a system that already works.
- In the cloud. Video or clips are sent to a service for analysis. Easy to add and manage remotely, but it uses upload bandwidth and puts footage with another vendor. Check per-camera subscription fees over five years.
Analog cameras on an old DVR generally need an encoder or replacement to benefit. Image quality still matters: detection fails on a camera that sees only silhouettes at night or looks straight into the sun. For choosing and placing cameras, see our security camera guide, and for doors, the access control guide.
Face recognition and the law
There is no general federal law on private use of face recognition, but several states and cities regulate it, and the penalties can be large.
- Illinois BIPA. The Illinois Biometric Information Privacy Act requires written notice and a signed written release before collecting a face geometry scan or other biometric identifier, a public retention and destruction policy, and a ban on selling biometric data. It gives individuals a private right to sue, with statutory damages of $1,000 per negligent violation and $5,000 per intentional or reckless one. A 2024 amendment limited repeated collection from the same person to a single violation, but exposure for a business scanning every customer can still be very large.
- Texas and Washington also have biometric identifier laws for commercial use, requiring notice and, in most cases, consent. They are enforced by the state attorney general rather than by private lawsuits.
- Portland, Oregon bans private businesses from using face recognition in places of public accommodation, such as stores, restaurants and hotels.
- New York City requires commercial establishments such as stores, restaurants and venues that collect biometric identifiers from customers to post a clear sign at each entrance, and bars selling that data.
- The FTC has treated careless face recognition as an unfair practice. Its 2023 order against Rite Aid barred the chain from using face recognition for security for five years after false matches led staff to confront customers.
More states and cities are adding rules, and comprehensive state privacy laws increasingly treat biometric data as sensitive data needing consent. Treat face recognition as a legal project. Check with a lawyer in every state where you operate before turning it on.
Signage and employees
Post clear signs that video surveillance is in use at entrances. Where you collect biometrics, the sign may be a legal requirement, as in New York City. Several states limit audio recording and cameras in places like restrooms and locker rooms, and many require notice to employees of workplace monitoring. Unionized workplaces may need to bargain over new monitoring. Put your camera, retention and access rules in writing.
Before you buy
- List the problem first: false alerts, slow search, after-hours intrusions, footfall counts.
- Check whether your cameras or recorder already support person and vehicle detection.
- If adding an appliance, confirm ONVIF compatibility with your camera models.
- Price cloud analytics per camera over five years, and check upload bandwidth.
- Decide in writing whether face recognition is allowed. Default to no, and get legal review before yes.
- Post signage, set a retention period and limit who can view and export footage.
