Cable schedule
Use the diagram reference to follow the same connection from the main diagram into the detailed explanation below.
| Diagram ref | From | To | Cable type | Core count | Power or data | Maximum distance | Purpose / important notes |
|---|---|---|---|---|---|---|---|
| C1 | IP Camera 1 | PoE NVR | Cat6 | 8 conductors / 4 pairs | PoE - confirm selected standard | Confirm against current Ethernet/PoE design and manufacturer instructions | Cat6 + PoE |
| C2 | IP Camera 2 | PoE NVR | Cat6 | 8 conductors / 4 pairs | PoE - confirm selected standard | Confirm against current Ethernet/PoE design and manufacturer instructions | Cat6 + PoE |
| C3 | PoE NVR | Local Monitor | HDMI cable preferred for high-resolution display, or VGA cable where supported | Connector-specific display cable | Display signal | Use the cable or approved extender limits for the selected resolution and equipment | HDMI / VGA local display |
| C4 | PoE NVR | Router / Modem | Cat6 | 8 conductors / 4 pairs | Data/control | Confirm against current Ethernet design | LAN uplink - no PoE |
| C5 | Router / Modem | Remote App | Internet / mobile data | No field cable across wireless path | Data/control | Not stated | Optional remote connection |
No maximum distance is invented. Where the exact figure depends on Ethernet design, voltage drop, current draw or the selected device, the schedule tells the installer to confirm it.
What the wiring actually is
Match each C reference to the same label on the main diagram and cable schedule. The line name alone is not a complete cable specification, so this table explains the physical cable, conductor or pair use, what it carries and how it normally terminates.
| Diagram ref | Cable shown | Physical path | Cable construction | Conductors or pairs | What it carries | Normal termination | Confirm before installation |
|---|---|---|---|---|---|---|---|
| C1 | Cat6 | IP Camera 1 to PoE NVR | Solid-copper Cat5e or Cat6 balanced Ethernet cable; Cat6 is the normal new-install choice. Do not use copper-clad aluminium. | Four twisted pairs / eight conductors, terminated consistently to T568A or T568B at both ends. | Ethernet data plus IEEE 802.3 PoE power when both the source and device support the required PoE class. | RJ45 plug, keystone or patch panel appropriate to the cable type; preserve pair twists. | 90 m permanent link / 100 m channel, PoE class, total switch budget, surge exposure and voltage drop for high-power devices. |
| C2 | Cat6 | IP Camera 2 to PoE NVR | Solid-copper Cat5e or Cat6 balanced Ethernet cable; Cat6 is the normal new-install choice. Do not use copper-clad aluminium. | Four twisted pairs / eight conductors, terminated consistently to T568A or T568B at both ends. | Ethernet data plus IEEE 802.3 PoE power when both the source and device support the required PoE class. | RJ45 plug, keystone or patch panel appropriate to the cable type; preserve pair twists. | 90 m permanent link / 100 m channel, PoE class, total switch budget, surge exposure and voltage drop for high-power devices. |
| C3 | HDMI cable preferred for high-resolution display, or VGA cable where supported | PoE NVR to Local Monitor | Factory-terminated HDMI is preferred for current displays; VGA is a 15-pin analogue alternative where the recorder supports it. | Use the complete manufactured display lead; it is not Cat6 and it does not connect to a PoE port. | Local video and, for HDMI, normally audio from recorder to monitor. | Recorder HDMI/VGA output to the matching monitor input. | Supported resolution, simultaneous outputs and cable/extension distance for the exact recorder and monitor. |
| C4 | Cat6 | PoE NVR to Router / Modem | Solid-copper Cat5e or Cat6 balanced Ethernet cable; Cat6 is the normal new-install choice. Do not use copper-clad aluminium. | Four twisted pairs / eight conductors, terminated consistently to T568A or T568B at both ends. | Ethernet data plus IEEE 802.3 PoE power when both the source and device support the required PoE class. | RJ45 plug, keystone or patch panel appropriate to the cable type; preserve pair twists. | 90 m permanent link / 100 m channel, PoE class, total switch budget, surge exposure and voltage drop for high-power devices. |
| C5 | Internet / mobile data | Router / Modem to Remote App | No data cable spans the wireless path. Each radio, router or mobile endpoint still needs its specified local Ethernet and power connection. | Radio link through free space; local device cables are documented separately. | Network data over Wi-Fi, licensed/unlicensed point-to-point radio or public mobile/internet service. | Aligned radios/antennas or the applicable router/cloud service. | Line of sight, Fresnel clearance, channel/interference, mounting, surge/earthing, bandwidth, data allowance and failover. |
Are any resistors required?
| Circuit | Resistor required? | Where it belongs | How to select it |
|---|---|---|---|
| Cat5e/Cat6 Ethernet or PoE | No external EOL resistor | Not applicable | The 100-ohm Ethernet impedance is a cable characteristic, not a resistor to install at the camera or switch. |
| 75-ohm CCTV coax | No external 75-ohm resistor in a normal camera-to-DVR run | Not applicable | Use true 75-ohm cable and BNC terminations. Do not add a loose resistor unless specialised test/distribution equipment explicitly requires it. |
| Fibre, HDMI/VGA or wireless path | No alarm EOL resistor | Not applicable | Use the correct optical modules, display cable or radio design instead. |
Never choose a resistor by cable colour or by the phrase "security cable". First identify the exact input, panel model and programmed supervision mode. An EOL resistor belongs at the end of the supervised circuit; placing it across the panel terminals defeats cable supervision.
HDMI or VGA local monitor connection
| Display path | When to use it | Cabling rule |
|---|---|---|
| HDMI | Preferred local display connection for 4K, 8K or other high-resolution output where the exact NVR and monitor support it | Use a compliant HDMI cable or an approved extender designed for the required resolution and distance. |
| VGA | Useful for a compatible legacy monitor or a model-supported secondary display; commonly lower resolution than HDMI | Use a proper VGA cable and confirm the NVR's supported VGA resolution and simultaneous-output behaviour. |
| Network client | A PC, browser, VMS workstation or app can view the recorder through the LAN | This does not replace the NVR-to-router Cat6 uplink and is not the same as the direct HDMI/VGA local display path. |
The monitor does not connect to a camera PoE port. Connect it to the NVR's labelled HDMI or VGA output. Display output, camera recording resolution and remote-app streaming resolution are separate settings.
Dahua, Hikvision and HiLook CCTV cabling applications
| Search/application intent | Physical layout | Current Security Wholesalers example | Platform note |
|---|---|---|---|
| Dahua CCTV system cabling diagram | Dahua IP cameras to built-in PoE NVR ports; separate NVR LAN port to router; HDMI or VGA to monitor | DHI-NVR4108HS-8P-AI/ANZ is a current 8-channel example with eight PoE ports and one HDMI plus one VGA output | DMSS / Dahua platform setup follows after local cabling works |
| Hikvision CCTV system wiring diagram | Hikvision IP cameras to PoE NVR ports; NVR LAN uplink to router; HDMI or VGA local display | DS-7608NI-I2-8P is a current 8-channel example with PoE, 4K HDMI and 1080p VGA | Hik-Connect / Hikvision platform setup is separate from the physical cable path |
| HiLook CCTV system cabling diagram | HiLook IP cameras to a compatible HiLook PoE NVR; separate LAN uplink; HDMI or supported VGA display | NVR-108MH-K/8P is a current eight-port example; confirm the exact kit/recorder supplied | HiLook is the value-focused Hikvision family, but model compatibility still needs checking |
| Other ONVIF/IP CCTV systems | PoE camera path may look similar | Do not assume plug-and-play activation, analytics, audio or full feature compatibility across brands | Confirm ONVIF profiles, codecs, firmware and recorder support before mixing equipment |
The brand phrases are consolidated into this canonical guide because the physical topology is materially the same. Separate brand pages would repeat the same diagram and risk competing with this page; exact model pages are only warranted when their ports, topology or setup problem is genuinely different.
What each cable does
- Camera Cat6: carries Ethernet data and PoE from each built-in NVR PoE port to one compatible IP camera.
- NVR LAN uplink: a separate Cat6 connection from the recorder's LAN/network port to the router or main network switch. It normally does not power the NVR.
- HDMI or VGA: carries the local display signal from the NVR to a monitor; it is not an Ethernet connection.
- Internet/mobile data: supports optional remote viewing after local camera recording and LAN operation have been proven.
- NVR power: uses the recorder's specified power input. Built-in PoE capacity must be checked against the combined camera load, including higher-power cameras.
Power requirements
Confirm the selected equipment's supply method, PoE class or DC input, total load and backup requirements before ordering. Keep lock power separate from data-path assumptions, calculate voltage drop for low-voltage loads, observe battery polarity and isolate any 230-240 VAC work to an appropriately licensed electrician.
How the wiring path works
Read the physical cable path first, then power, relay or I/O paths, network addressing and finally app or cloud registration. A device that appears offline may have a physical link, power, addressing or configuration fault; Wi-Fi and cloud registration should not be used to hide an incorrect LAN design.
Practical installation sequence
- Confirm every exact device model and current manual.
- Confirm cable types, routes, separation and distances.
- Check PoE or DC power capacity and site voltage drop.
- Mount and cable devices with power isolated.
- Test continuity, polarity and earth/surge arrangements where applicable.
- Power one subsystem at a time.
- Activate and address network devices.
- Configure relay, call or recording behaviour only after the physical path works.
- Test local operation, remote operation and failure modes separately.
- Record final models, IP addresses, cable IDs, settings and diagram revision.
Common mistakes
- Assuming a port provides PoE without checking the port and total switch budget.
- Confusing a recorder's isolated camera ports with its main LAN uplink.
- Powering a lock from an unsuitable relay or supply.
- Guessing normally-open, normally-closed, polarity or resistor details.
- Ignoring voltage drop, surge exposure or power-failure behaviour.
- Treating app setup as proof that the physical cabling is correct.
Troubleshooting
| Symptom | Likely cause | Test | Corrective action |
|---|---|---|---|
| Device has no power | Incorrect supply method or exhausted PoE budget | Check port status and measure only with the correct procedure | Match the power source to the exact device manual |
| Device powers but is offline | Wrong LAN path, addressing or activation state | Confirm link lights, subnet, gateway and device state | Correct physical LAN and addressing before cloud setup |
| System works locally but not remotely | Internet, DNS, account or cloud registration issue | Prove local operation first, then test WAN services | Correct router or account configuration; do not recable a working local link |
| Relay or lock action fails | Wrong contact logic, power path or load assumption | Test relay and lock supply as separate subsystems | Use the exact manual and suitable lock PSU; confirm egress requirements |

Frequently asked questions
Can I buy cable using this guide?
Use the cable schedule and buying list to shortlist the cable, then confirm the exact equipment model, route, distance, environment and manufacturer requirements before ordering.
Can cable distance or power capacity be assumed from this drawing?
No. Confirm the selected devices, PoE budget, voltage drop, cable construction and current manufacturer instructions.
Where do terminal names and resistor values come from?
They must come from the exact current manual for the selected model. Do not transfer terminal names, polarity or resistor values from a similar product.
Can this replace the manufacturer manual?
No. It is a planning and support reference only and does not replace manufacturer instructions, licensed work, fire engineering, egress assessment or site commissioning.
Does this work as a Dahua CCTV system cabling diagram?
Yes. It represents the normal high-level layout for a Dahua PoE NVR such as the DHI-NVR4108HS-8P-AI/ANZ: each IP camera uses Cat6 to a built-in PoE port, the NVR LAN port connects separately to the router, and a local monitor connects by HDMI or VGA. Confirm the exact Dahua NVR manual, PoE budget and supported output resolution.
Does this apply to Hikvision and HiLook PoE NVR systems?
Yes. Hikvision DS-7600-series PoE NVRs and HiLook PoE NVRs use the same broad camera-to-recorder, recorder-to-router and recorder-to-monitor topology. Port counts, PoE budgets, display resolution, plug-and-play behaviour and app setup vary by exact model.
Should the NVR monitor use HDMI or VGA?
Use HDMI where the monitor and recorder support the required high-resolution output. VGA remains useful for a compatible legacy or secondary display. Confirm the exact NVR's HDMI/VGA resolutions and whether both outputs can operate simultaneously.

Australian installation and safety notice
General guide only. Confirm current manufacturer instructions and site requirements. Work involving 230-240 VAC must be completed by an appropriately licensed electrician. Fire-release interfaces, emergency exits and door locking require project-specific compliance assessment. Keep mains and ELV cabling appropriately separated, isolate power before work, observe battery polarity and calculate voltage drop for the real load and cable run.
