Video Surveillance for Small Businesses — What You Need to Know

A video surveillance system isn't just a security tool — it's evidence, prevention, and a management tool in one. For a small business, the right system can prevent theft, help resolve disputes, and provide peace of mind.

But before you buy and install anything, you need to understand the basics. Here's the complete guide for small businesses.

Why does a small business need video surveillance?

• Theft protection — from both customers and employees
• Evidentiary value — for incidents, disputes, or insurance claims
• Prevention — visible cameras reduce the frequency of theft and vandalism
• Monitoring remote locations — manage your business even when you're not there
• Employee protection — documents working conditions and workplace incidents

Types of cameras — which one is right for you?

Analog cameras (traditional)

Cheaper, but with lower image quality. Require coaxial cable. Suitable when replacing an existing system.

IP cameras (digital network cameras)

High resolution, easy network integration, remote access from a phone or computer. We recommend IP cameras for new installations.

PTZ cameras (Pan-Tilt-Zoom)

Can rotate and zoom remotely. Suitable for larger perimeters or monitoring entrances.

Indoor/outdoor cameras

Make sure you choose the right type for the environment — outdoor cameras need a higher protection rating (IP66 or IP67).

How many cameras do you need?

There's no universal answer, but here's a rough framework:

• Small shop or office (up to 50 sq m): 2-4 cameras
• Warehouse or production space: 4-8 cameras
• Entrance and parking lot: at least 2 cameras (entry and exit)
• Areas with a cash register or safe: at least 1 camera required

It's a good idea to have a technician survey the site before deciding on the number — a lot depends on the actual layout of the space.

Core components of the system

• Cameras — the type and number depend on your needs.
• NVR/DVR recorder — the device that stores the footage. NVR is for IP cameras, DVR is for analog ones.
• Hard drives — determine how far back you can review footage. With 4 cameras at 1080p, a 2TB drive covers about 7-10 days of continuous recording.
• Cables and infrastructure — Cat6 cables for IP cameras or coaxial for analog ones.
• Installation and configuration — camera angles and positions are critically important. A poorly placed camera may not capture anything useful.

Remote access — monitor from anywhere

Modern IP systems let you watch live video and recorded footage from your smartphone or computer, wherever you are in the world. This is especially valuable for:

• Owners managing more than one location
• People checking on a location after hours
• Verifying an alert notification

Legal aspects of video surveillance

In Bulgaria, video surveillance is regulated by GDPR and the Personal Data Protection Act. Key requirements:

• Visible signage ("This area is under video surveillance")
• Footage must not be kept longer than necessary (typically 30 days)
• Monitoring is not allowed in places where employees have a right to privacy (restrooms, changing rooms)

SNM Support also advises on the legal requirements during installation.

How much does installation cost?

Prices depend on the number of cameras, the type, and the complexity of the installation. A standard system typically takes around 2 weeks to install. The main costs include:

• Cameras: from 60 to 300 euros each, depending on type
• NVR recorder: from 200 to 600 euros
• Installation and configuration: quoted individually
