How to make a surveillance line using fiber optic cable
The media converter turns the electric signal into a fiber optical signal so the camera's video can transfer over the fiber optical cable. Also, you'll need RJ45 and SFP fiber ports. IP cameras that are part of a modern surveillance system are deployed using PoE technology that involves the use of copper based network cabling like CAT5e or CAT6 that has a data transmission limit of 100m (328ft). While that is adequate for installations for a home or small business, large scale. In this video, we walk you through a real-world IP camera installation project that involves setting up a network for 10+ cameras across a 150-meter distance between a garage and a control room.

Communication optical cable away from low voltage line
The National Electrical Code establishes specific minimum distances when communications cables must run near power and light circuits. This practice is mandatory for two distinct reasons: ensuring the safety of the structure and its occupants, and preserving the integrity of sensitive data. Maintaining proper separation between power, data, and limited energy cabling is foundational to system performance, safety, and code compliance. Separation isn't just an EMI precaution — it protects signaling, reduces rework, and ensures pathways meet inspection expectations across risers. TECHNICAL GUIDELINE July 30, 2020 TG030 Rev.
