🛡️📹 CCTV Siamese Video & Power Cable
This cable merges two essential lines—video and power—into a single, conjoined cable jacket. It’s designed for analog CCTV systems, allowing cameras to transmit footage while receiving power through the same cable run.
🔧 Cable Format
- Video Line: Coaxial cable
- Power Line: 18AWG 2-conductor (positive & ground)
- Jacket: Unified PVC sheath with split capability
- Connectors:
- BNC for video (male/female)
- DC barrel or terminal block for power
- Lengths: Available in bulk spools (500–1000ft) or premade patch cables (25–150ft)
🖥️ Compatible Devices
- 📷 Analog CCTV cameras (BNC output)
- 📼 DVRs with BNC video inputs
- 🔌 12V DC or 24V AC power supplies
- 🧰 Power distribution boxes
- 🏢 Home, commercial, and industrial surveillance systems
✅ Common Uses
- 🧩 Simplify camera installation with one cable run
- 🏠 Home security setups with multiple wired cameras
- 🏢 Commercial surveillance with centralized power
- 🛠️ Custom-length installations using bulk cable
- 🔌 Power and video routing from DVR to remote cameras
🧠 Signal Format Notes
- Video: Analog signal via coax
- Power: Low-voltage DC or AC (camera dependent)
- No Data or Audio: Strictly video + power
- No IP Support: Not for networked or PoE cameras
- Max Distance:
- Video: ~700 ft (without amplifier)
- Power: ~300 ft (depends on voltage and current draw)
⚠️ Things to Watch Out For
- 🔌 Voltage drop over long runs—use thicker gauge or local power
- 🧯 Not compatible with IP or PoE cameras
- 🧼 Keep power and video ends clearly labeled to avoid miswiring
- 🧪 Avoid sharp bends—can damage coax shielding
🛠️ Quick Tips for Beginners
- 🧪 Test each run before final installation
- 🧼 Use cable clips or conduit for clean routing
