Solar CCTV for Construction Sites
Return to Solar CCTV Systems Australia hub
Use Case Guide
Best fit by site size
Most small sites: start with the VIGI solar kit. Broader monitoring jobs: step to the Hikvision solar PTZ. Planned deterrence-heavy PTZ jobs: consider the Dahua 120W solar PTZ, noting the longer lead time.
Default small-site answer
Product: VIGI solar kit.
Best for: one gate, one site shed, one container, one temporary compound.
Broader monitoring pick
Product: Hikvision solar PTZ.
Best for: broader frontage, access road, laydown area or larger monitored scene.
Planned higher-risk option
Product: Dahua 120W solar PTZ.
Best for: planned projects that want a richer deterrence feature set and can wait for stock.
Where solar usually goes on a construction site
- Main gate
- Site shed or office
- Tool container
- Temporary compound
- Material laydown area
- Changing frontage or rear-lane exposure
Reference layout: gate, shed and compound
What usually works
One gate + one shed
Pick: VIGI. Why: easiest and fastest. What not to do: overcomplicate it with a PTZ too early.
One broad frontage
Pick: Hikvision PTZ. Why: genuine zoom and a larger monitored scene. What not to do: let it become the only evidence view on the site.
Planned high-risk frontage
Pick: Dahua PTZ. Why: richer deterrence features. What not to do: choose it for an urgent job and then get caught by lead time.

Real quote scenarios
| Scenario | Typical quote shape | Why this design works |
|---|---|---|
| Small townhouse build | One solar 4G camera covering entry/material laydown, app alerts and clear relocation plan as the site changes. | Construction views move. The quote should include how the camera will be repositioned as fencing and access change. |
| Medium commercial site | Two to four solar cameras, entry view, material storage, site office and rear access, with escalation contacts and weekly health check. | Separates vehicle entry from theft-prone storage areas and gives the builder a practical review workflow. |
| Large staged project | Solar plus powered or bridge-linked cameras, multiple zones, PTZ only where actively useful, and a documented stage-change plan. | The system needs to evolve with the build, not be treated as a fixed permanent CCTV design. |
Authority checklist: solar sizing and failure points
Solar CCTV succeeds or fails on the power budget. The camera name matters, but the real design question is whether the panel, battery, pole, enclosure, mobile signal and recording mode suit the worst week of the year, not just a sunny demo day.
| Design item | What to confirm | Common failure |
|---|---|---|
| Power budget | Camera load, 4G load, standby draw and night operation. | Battery sized for average weather instead of poor-weather periods. |
| Panel position | North-facing exposure, shade, tilt and theft/vandal resistance. | Panel mounted where trees, sheds or seasonal sun reduce charge. |
| Connectivity | 4G signal strength, SIM plan, data use and antenna position. | Camera works during setup but drops events once installed remotely. |
| Recording workflow | SD card, NVR link, cloud/app event review and export expectations. | Buyer assumes full CCTV behaviour from a constrained solar/4G site. |
Product paths to compare
VIGI solar kit
Good first comparison for straightforward gates, sheds and temporary sites where a clean kit path matters.
Hikvision solar PTZ
Compare where the site is broader and the buyer genuinely needs PTZ reach, not just a single fixed view.
Installer handover checklist
- Record panel orientation, battery size, SIM provider and expected maintenance interval.
- Test the camera after dark and after at least one real charge cycle where possible.
- Document what happens when the battery is low, the SIM fails or the SD card fills.
- Confirm who receives app alerts and who is responsible for checking the system after storms or site changes.
Frequently asked questions
Is solar CCTV as reliable as powered CCTV?
Not usually. It can be excellent where power is unavailable, but it needs more care around battery, weather, signal and maintenance.
Should I use 4G or a wireless bridge?
Use 4G when the site is isolated. Use a bridge where there is line of sight back to a powered network and the link can be installed properly.
