What Are the Different Types of CCTV Systems? Full Guide

AI Overview: Quick Answers About CCTV System Types

Q1: What are the main types of CCTV systems?
The main types of CCTV systems include Analog (DVR-based), IP (NVR-based), PoE systems, Wireless (WiFi) systems, 4G/LTE CCTV systems, and AI-powered smart surveillance systems. These systems vary based on transmission method, installation type, resolution, and application environment.

Q2: What is the difference between DVR and NVR systems?
A DVR system works with analog cameras using coaxial cables. An NVR system works with IP cameras over Ethernet networks and supports higher resolution, remote access, and smart AI features.

Q3: Which CCTV system is best for commercial use?
IP PoE CCTV systems with AI detection are the most widely used in commercial and industrial projects due to stability, scalability, and high image quality (4MP–4K).

Q4: Are wireless CCTV systems reliable?
Wireless systems are suitable for homes and small offices. For professional installations, wired PoE or 4G LTE systems provide more stable long-term performance.

Q5: What CCTV system is suitable for remote areas without internet?
4G LTE solar-powered CCTV systems are ideal for farms, construction sites, highways, and rural areas without broadband.

Security monitoring has evolved from basic video recording to intelligent, cloud-connected surveillance ecosystems. Today, installers, distributors, and project contractors must understand the different types of CCTV systems to choose the right solution for each scenario.

This complete guide explains CCTV system categories by technology, design, functionality, and application, while providing practical insights for professional buyers.

1. Analog CCTV Systems (DVR-Based Surveillance)

Analog CCTV systems are the traditional surveillance solution that dominated the market for decades.

How Analog CCTV Systems Work

• Cameras transmit video signals through coaxial cables

• Signals are processed and stored in a Digital Video Recorder (DVR)

• Power is supplied separately

• Video can be viewed locally or remotely (if network-enabled DVR)

Modern analog systems now support HD-TVI, HD-CVI, and AHD technologies, allowing 720p and 1080p resolution over coaxial cable.

Advantages

• Lower hardware cost

• Suitable for upgrading old analog infrastructure

• Stable wired transmission

• Simple setup for small shops

Limitations

• Resolution typically lower than IP systems

• Complex cable management

• Limited scalability

• Less advanced AI capability

Ideal Applications

• Small retail stores

• Warehouses replacing legacy systems

• Budget-sensitive projects

Although analog systems remain relevant in price-driven markets, the global trend is shifting toward IP-based solutions.

2. IP CCTV Systems (Network Video Surveillance)

IP CCTV systems are the current industry standard.

How IP CCTV Systems Work

• Each camera has its own IP address

• Video data is transmitted digitally over Ethernet cables

• Video is recorded in a Network Video Recorder (NVR)

• Remote viewing via mobile app or PC software

Key Features

• High resolution: 4MP, 5MP, 8MP (4K)

• Smart compression (H.265 / H.265+)

• Remote monitoring

• Intelligent detection

• Easy integration with third-party VMS

Why PoE Technology Matters

Power over Ethernet (PoE) allows:

• Power + data transmission through one cable

• Reduced installation time
