Sydney has the widest spread of site types of any Australian city, and the practical constraints change completely between the inner suburbs and the western estates. Treat it as three jobs.
Strata and shared buildings
A large share of Sydney business premises sit inside strata: office floors, mixed-use blocks, industrial unit complexes at Rydalmere or Silverwater, and retail tenancies under apartments. The camera plan is the easy part; the approvals are not.
Expect to document what each camera sees, where the recorder lives, who holds the credentials, and how long footage is kept, before a body corporate or building manager signs off. Common areas — lobbies, lifts, basement car parks, bin rooms — are usually the building's decision, not the tenant's, so a tenant-funded system often ends up covering only its own doorway and interior. Cameras must not look into another tenancy, a residential balcony or a bathroom. That is general information rather than legal advice: NSW has its own surveillance devices and workplace surveillance rules, and our CCTV law overview explains the shape of them without replacing proper advice.
Older terraces and heritage shopfronts
Through Newtown, Surry Hills, Marrickville, Balmain and Paddington, the limiting factor is almost always cable path. Solid brick walls, no ceiling cavity worth the name, shared party walls, and facades where visible conduit is not acceptable or not permitted. Realistic options are surface conduit run on the inside, cable routed through an existing riser or shopfront bulkhead, or a smaller camera count placed where a path exists rather than where the textbook wants it.
Shopfronts also face a hard lighting mix — bright western sun on glass by day, streetlight and headlights at night. Wide dynamic range and a sensible mounting height matter more than megapixel count. Mounting a camera directly above a door at two metres and relying on infrared will give you the top of someone's head, well lit, and nothing useful about their face.
Western Sydney industrial
Eastern Creek, Erskine Park, Wetherill Park, Smithfield, Ingleburn, Marsden Park: large sheds, big hardstand, trailer and container storage, and long fence lines. Three things shape the plan.
- Heat. Western Sydney runs hot — well above the coastal temperature on summer afternoons. Recorders and PoE switches need ventilated, conditioned space, not a steel cupboard against a west wall.
- Vandalism and graffiti. Perimeter cameras get tagged, turned and cut. Mount high, run cable in conduit, and make sure one camera can see another.
- Distance. A 200 metre fence line is not one camera's job. Where buildings or gatehouses are separated, fibre between them beats long copper runs and avoids carrying surges across the site.
Coastal and bayside sites — Botany, Port Botany, Brookvale, the eastern beaches — add salt air, which attacks fixings, glands and exposed connectors long before it affects the camera.
Connectivity
Inner-city buildings vary enormously: some have fibre to the premises, others sit on an in-building copper network the landlord controls. Industrial estates west commonly have good fibre options. The number that matters is upload, because that is what limits remote viewing and offsite alerting, not the cameras.
Keep cameras on their own VLAN and reach the system through a VPN or managed remote connection rather than forwarding a port to the recorder. Our network and bandwidth guide sets out the sizing.
What Sydney businesses want AI monitoring for
Multi-tenant buildings mostly want after-hours activity in common areas flagged rather than watched: a person in a basement car park or loading dock outside the hours set, emailed with the frame attached. Retail wants door counts and dwell patterns. Industrial sites want tripwires across fence lines and gates, vehicle counts, and a searchable timeline of dock activity so a query about a missing pallet takes minutes rather than an afternoon. Several sites use plate reading at the gate to match arrivals against bookings. The system flags and alerts; people still decide what it means.
Who does the work here
We install directly on the Gold Coast, in Brisbane and across South East Queensland. For Sydney sites we work with local installers for the cabling and mounting, and set up and support the AI layer, the recorder configuration and the alerting remotely. We do not have a Sydney branch, and it is worth asking any installer — including whoever we introduce you to — for their licence and insurance details.
