What Is Cat5e Ethernet Cable?

Cat5e (Category 5e) is a twisted-pair Ethernet cable commonly used in professional IP security camera systems. It carries both data and power over a single cable when used with PoE.

• Supports distances up to 328 ft (100 meters)
• Handles PoE power for IP cameras
• More reliable than Wi-Fi for 24/7 recording
• Industry standard for professional surveillance

Why Professional IP Cameras Use Cat5e

Unlike consumer Wi-Fi cameras, SureVision IP cameras use hard-wired Ethernet connections to ensure stable video, consistent power, and uninterrupted recording.

• One cable = power + video (PoE)
• No batteries or wireless dropouts
• Higher bitrates for true 4K video
• Better security and reliability

How PoE (Power over Ethernet) Works

PoE allows a single Cat5e cable to transmit both electrical power and network data from a PoE NVR or PoE switch directly to an IP camera.

This eliminates the need for separate power supplies at each camera location, making installs cleaner and more reliable.

Connecting Cameras: PoE NVR vs PoE Switch

PoE NVR (Most Common)

• Cat5e runs directly from camera to NVR
• Plug-and-play camera discovery
• Ideal for systems up to 16 cameras

PoE Switch (Larger Systems)

• Used for 16+ camera systems
• Cameras connect to PoE switch
• Single network uplink from switch to NVR
• Simplifies long cable runs

Cat5e Connectors: Crimp-On vs Tool-Less

Crimp-On RJ45 Connectors

Crimp-on connectors require a crimping tool and proper wire alignment (T568B standard). They offer the most secure termination when installed correctly.

Tool-Less / Twist-On RJ45 Connectors

Tool-less connectors are popular for DIY installs. Wires are inserted, aligned by color code, and twisted closed — no crimping required.

These are ideal for homeowners and installers who want speed without sacrificing reliability.

Tools Needed for Cat5e Camera Installations

• Ethernet cable stripper
• RJ45 crimping tool (for crimp-on connectors)
• Wire cutter
• Cable tester (recommended)
• Fish tape or pull rods (for walls/attics)

Best Practices for Running Cat5e Cable

• Do not exceed 328 ft per cable run
• Avoid running parallel to high-voltage power lines
• Use outdoor-rated cable for exterior runs
• Label both ends of every cable
• Leave service loops for future adjustments
