If your old CCTV system is failing but the cabling runs are still good, we can upgrade your cameras and NVR while reusing what's already in your walls. Built for Brisbane body corps, commercial property managers, and single-business owners who don't want a rip-and-replace.
Before any retrofit, we walk every cable run with you and test continuity, length, and signal quality. Here's the typical pattern of what survives versus what needs to swap.
If your CAT5e/CAT6 runs are intact and within length (90m max for PoE), or your RG-59/RG-6 coax tests clean, we reuse all of it. We also keep your conduit, mounting brackets, junction boxes, and ceiling/wall penetrations. That's where the labour savings come from.
This is the upgrade. Cameras swap to current-gen Dahua 4K IP units with AcuPick AI or TiOC active deterrence. Your NVR swaps to a modern Dahua AcuPick recorder with H.265 compression so the same hard drive holds 2-3x more footage.
If you have a budget PoE switch from 5+ years ago we'll often swap it for a managed Gigabit unit. Same for any spinning-disk drives older than 3 years — we'll quote a Purple/SkyHawk surveillance-grade replacement. Existing monitors stay.
Four-step process. Most residential retrofits finish in 1-2 days. Multi-building body corp jobs run as phased cutovers, one block at a time, so the property never goes fully offline.
We walk every cable run, test continuity with a cable certifier, measure run lengths, check PoE budget, and document NVR cabinet space. Free of charge across Brisbane, Gold Coast, Sunshine Coast.
You receive a written report: what's reusable, what needs replacement, expected camera positions, and a fixed-price quote. No surprise day-of costs.
Pull old cameras, mount new ones on existing brackets, terminate cables, install and configure new NVR, test every channel, and verify night vision plus AI detection zones.
DMSS app setup on your phones, push notifications configured, AI rules tuned to your property, training on remote viewing and playback. Ongoing remote management available via dealer portal.
Four specific technical features that make retrofit cheaper than a full rip-and-replace install — without compromising the upgrade.
ONVIF is the open IP camera standard. A Dahua NVR can record from any ONVIF-compatible camera, including Hikvision, Axis, Bosch and most generics. We can mix and match if some of your existing cameras are still solid.
Old RG-59/RG-6 coax can carry full IP camera signal via EoC (Ethernet over Coax) converters or HDCVI Dahua cameras over the existing BNC runs. No new cabling, no new conduit, no patching ceilings.
Modern PoE+ injectors deliver up to 30W per port over CAT5e at 100m. Your 8-port PoE switch becomes a 16-port managed one, no recabling. Cameras get power and data on the same wire.
If your old alarm panel is also failing, we can layer an AJAX Hub 2 wireless system over the existing hard-wired sensor runs using AJAX Transmitter modules. Keep the wires, add cloud monitoring.
We walk your property, test every cable run, and provide a written compatibility report with a fixed-price quote. No obligation. Available across Brisbane, Gold Coast, Sunshine Coast, and Ipswich.
