🔧 How to Install & Configure Dahua PTZ SD49225DB-HC (25X HDCVI 2MP)

Complete Step-by-Step Setup Guide

The Dahua SD49225DB-HC is an HDCVI-based PTZ dome camera that uses coaxial cabling and supports up to 700m transmission. Installation requires correct mounting, power supply, PTZ control wiring, and DVR configuration.

Below is the complete workflow.

🛠 Tools & Items Required

• Dahua SD49225DB-HC PTZ Camera

• 24V AC power supply (or as specified)

• Coaxial cable (RG59) & BNC connectors

• PTZ control wires (RS485 A/B)

• Dahua HDCVI DVR (XVR recommended)

• Drill, screws, wall plugs

• Network tester (optional)

• Surge protection device (recommended)

1️⃣ Mounting the Dahua PTZ Camera

1. Choose a stable surface: wall, ceiling, pole, or bracket.

2. Ensure full 360° pan clearance (no obstruction).

3. Mark the drilling points using the mounting plate.

4. Install anchors, screws, and bracket.

5. Mount the camera securely and tighten the locking screws.

Important: PTZ cameras must be firmly mounted — any vibration will affect zoom/focus.

2️⃣ Cabling & Power Connection

✔ A. Video Cable (HDCVI)

• Use coaxial RG59 with BNC connectors.

• Connect camera → BNC → DVR video input.

✔ B. Power

• The SD49225DB-HC uses 24VAC.

• Connect 24VAC+ and 24VAC- from power adapter to camera input.

• Avoid sharing power with other heavy-load devices.

✔ C. PTZ Control Wiring (RS485)

• Connect RS485 A → DVR A

• Connect RS485 B → DVR B

• Use twisted-pair cable (Cat5/6 pair is fine).

Polarity matters — wrong polarity = PTZ not moving.
