Network topology commonly used termination of the bus structure, does not support a round or star-shaped network. All node is serial connected by one bus is a good choice, in the picture above, the general network topology of A8-05B system is shown. N nodes are connected in a multipoint network. For higher speeds and longer lines, the termination resistances are necessary on both ends of the line to eliminate reflections. Use 100 Ω resistors on both ends (need only if wire length > 2km). The network must be designed as one line with multiple drops, not as a star. Although total cable length maybe shorter in a star configuration, adequate termination is not possible anymore and signal quality may degrade significantly. In Diagram 1 which showed next, b, d, f is right connection and a, c, e is wrong connection.
When using shield network wire (STP), Should maintain the continuity of the shielding layer of smooth, and connect Earth at one point, as shown in diagram 
Wire required System used CAT-5E UTP and STP cable. How to choose qualified CAT-5E cable? The resistance of each wire must ≤35Ω when length is about305M (FCL length). Door-station to Power Supply used RVV4*0.5, to lock used RVV2*0.5. Warning: Door-station’s picture will not full display in Visual Room-station’s screen when Room-station quite different from the video power supply, at appropriate locations in the building bus to increase a power supply can solve this problem. General video power supply from the visual Room-station of the maximum distance could not exceed 30 meters.
Because RJ-45 standard is made up for in-door using only, it is poor damp-proof and very easily be dirtied or oxidized. If a RJ-45 Head is broken, there are professionals hold professional tools required to repair the fault, this will lead to higher maintenance costs. Scotchlok is exactly what we need. Over 45 years ago, 3M introduced the industry's original insulation displacement connector - the Scotchlok Connector UR. Today, with increased demand for high-speed and high-bandwidth networks, the complete series of 3M connectors and tools has evolved again. Please visit www.3M.com for more Scotchlok’s information.
