Common Wiring Colours These are common colour codes for various security equipment, however check with your hardware’s installation documentation before connecting to an existing system! 4-core 4-core alt. 6-Core + PWR + PWR + PWR ALARM SIG ALARM SIG ALARM GND ALARM GND ALARM SIG TAMPER SIG COM (TAMPER) TAMPER GND PWR GND PWR GND PWR GND 05062038 CCTVCOM24-1M 05062039 CCTVCOM24-100M 05062045 CCTVCOM24-250M RG59U & POWER COMBO CABLE f f Bonded CCTV RG59U and Double Insulated 2 core power cable f f Easy to install power and video at same time! 05052023 RG59U-1M 05052024 RG59U-100M RG59U SOLID CORE COAX CABLE f f 1/Ø0.65mm Copper Clad Steel core f f Braided screen: 16/7/0.14 OFC(88%) f f Wave impedance: 72±3 Ohm (@ 200MHz) f f Capacitance: 73±5pF/m 05492050 6RCCB 6MM 05492051 6RCCW 6MM 05492060 15RCCB 15MM 05492061 15RCCW 15MM NAIL-DOWN CABLE CLIPS f f 6mm round cable clip to suit RG59U f f Pack of 100 pieces f f 15mm square cable clip to suit bonded RG59U+Power or Twin RG59U cables 05062008 4X7-.2SC-1M 4-core 05062024 6X7-.2SC-1M 6-core 4-core / 6-core cable f f 4-core (4.8mmØ) f f 6-core (5.5mmØ) f f Great for alarm signal lines There are two common applications – Stepping down higher voltage DC power and secondly, converting from 24V AC power down to 12V DC. For Doss CCTV, we test cabling and cameras at 100m distance. The biggest limitation to the distance is the voltage drop in the cabling – if you feed 12V into the system, 100m later, you might be left with, say, 7V. If it is a 200m or 300m run, at some point the voltage will be too low to operate the cameras. One solution is to input say 24V DC and use a voltage converter ensure the supply to the camera is regulated at a safe 12V DC level. 24V AC is also commonly used in security installations. Since all Doss cameras operate on 12V DC, you’ll need a voltage converter behind the camera to fit your camera into an existing 24V AC System. 33774930 PC1A DC/AC TO 12VDC CONVERTER f f Screw Terminals f f Regulated 1000mA max f f Convert AC: 18-26VAC or DC: 18-28VDC to 12VDC 30978019 PW8019 2.5MM SOCKET TO 2.1MM PLUG f f 2.5mm Socket to 2.1mm Plug f f Can convert plug sizes of power supplies for use with 2.1mm DC extension and splitter leads 30978018 PW8018 SCREW TERMINATED DC PLUG f f 2.1mm DC plug 30978050 PW8050 SCREW TERMINATED DC SOCKET f f 2.1mm DC socket Distance Camera Max +12V Camera Min Volts Regulated Voltage Cable Voltage 33774925 PC500 DC/AC TO 12VDC CONVERTER f f 2.1mm DC plug f f Regulated output, 500mA max f f Convert AC: 14-24VAC or DC: 15-30VDC to 12VDC FIGURE-8 24/0.2 TWIN-CORE 05093003 2X24-.2PB-1M BLACK 05093004 2X24-.2PBR-1M BROWN 05093005 2X24-.2PW-1M WHITE 05093006 2X24-.2PG-1M GREY DOUBLE INSULATED FLAT 24/0.2 TWIN-CORE 05093020 2X24-.2DSW-1M WHITE 05093026 2X24-.2DSR-1M RED TWIN POWER CABLE f f 2-core x 24 strand (0.2mm).
