About coaxial cables
This article provides the information of recommended coaxial cable.
Make sure that no other devices are connected to the coaxial cable.
Recommended coaxial cable: RG-6/U
- Insulation resistance: 1 MΩ or more at 500 VDC
*A maximum of 60 VDC is applied to the coaxial cable.
- Loop resistance: 20 Ω or less (at 500m)
To stably supply power to the camera side unit, the loop resistance must be 20 Ω or less at length 500 m (4 Ω/100 m).
LAN cables used to connect network cameras compliant with PoE standards:
100 Ω balanced as defined by ISO/IEC11801-2002.
(IEEE802.3af Annex 33B）
*If the resistance of the LAN cable between the camera side unit and a PoE network camera is larger, voltage drops and operation becomes unstable.
When using flat-type LAN cables, pay careful attention to the drop in voltage as failures caused by it have been reported.
