Safire cabling and PoE engineering: Cat6 vs coax reuse
Before a Safire camera goes on the wall, the cable plant and the power budget decide whether the install is clean or a callback waiting to happen. This is how we plan the cabling topology and the PoE load — including when it's honest to reuse existing coax instead of re-cabling everything to IP.
How we plan cabling and power
Survey the existing plant
We check what's already in the walls — coax runs of unknown or mixed standard, spare conduit, or a blank slate — before deciding on topology.
Choose structured cabling or coax reuse
New runs get Cat6/Cat6a home-runs per camera; existing coax can often stay in service behind a Safire 5-in-1 XVR instead of a full re-cable.
Budget the PoE load
We sum the camera count and draw class against the NVR's or switch's rated PoE budget, always checked against the specific model's datasheet.
Label and document for handover
Every run and port gets an IEC 61439-style label so the as-built matches the drawing on day one and years later.
What disciplined cabling and power planning gets you
One recorder, five signal types
Safire's XVR accepts HDTVI, HDCVI, AHD, CVBS and IP on the same box, which is exactly what makes a coax-reuse decision possible without guessing the existing standard.
Cat6/Cat6a home-runs
Each IP camera gets its own labelled run back to the panel — no daisy-chaining, no shared segments to troubleshoot blind.
Coax reuse as a deliberate lever
If the existing coax plant is sound but its exact analog standard is unclear, the 5-in-1 XVR lets it stay in service rather than forcing a rip-and-replace.
PoE power budgeting, done honestly
Total camera draw has to sit inside the NVR's or switch's rated PoE budget — the exact wattage always depends on the specific models, so we check the datasheet rather than assume a number.
Separation from power cabling
Low-voltage runs are routed and separated from mains cabling per standard practice, reducing induced noise and simplifying future fault-finding.
Honest about ONVIF's limits
Safire IP gear generally supports ONVIF for basic video-stream interoperability, but the full Safire Control Center feature set is built for Safire NVR/XVR plus Safire cameras, not any ONVIF box on the market.
What's in a cabling & PoE engineering pack
A documented plan an installer can actually build from, not a verbal recommendation.
- Site survey findings and existing-plant assessment

- PoE load note against the chosen NVR/switch datasheet
- DIN-rail and patch-panel labelling scheme
- Handover documentation pack for the maintaining electrician
Frequently asked questions
Can we keep our existing coax cabling instead of pulling new Cat6?
Often yes. Safire's XVR is a '5-in-1' recorder that accepts HDTVI, HDCVI, AHD, CVBS or IP on the same box, so an existing coax plant of uncertain or mixed standard can usually stay in service. The trade-off is honest: the full Safire Control Center ecosystem is wider on IP.
How much PoE power do we need to budget per camera?
It depends on the specific camera and NVR/switch models — we don't quote a blanket wattage figure. Always check the rated PoE budget on the datasheet of the exact hardware in use before finalising camera count.
How long is footage kept on a Safire recorder?
Retention depends on configuration — resolution, bitrate, compression, motion-detection settings and installed HDD capacity all change the number. There's no fixed figure; it's calculated per project against the chosen model's specification.
Does ONVIF mean we can mix Safire with another brand's NVR?
ONVIF gives basic video-stream interoperability between manufacturers, which is genuinely useful. But the full feature set of the Safire ecosystem, including Safire Control Center, is designed around Safire NVR/XVR paired with Safire cameras.
What does the labelling and documentation cover at handover?
Every cable run, patch port and DIN-rail position is labelled to a consistent scheme in line with IEC 61439-style panel discipline, so the next electrician on site can read the installation without guesswork.
