CCTV for Construction Site: Why Solar Cameras Fall Short
Thieves steal even from a house that is not finished. A customer building a new home told us the iron rods unloaded at the site had vanished, and the electrician's wires had been pulled out of the walls. He already had a solar camera, but it recorded nothing during the theft. If you are planning CCTV for construction site security, here is what we recommend, and why we advise against solar cameras.
Why solar cameras fail at a construction site
A solar camera is attractive because it needs no wiring, but several practical problems show up at a building site:
- It switched off at night. The customer's camera went off at about 1 am, exactly when the thieves came, so there was no recording.
- It records only when it senses a person. To save the battery, many solar cameras record only on motion. The sensor detects people only to about 5 m, and when the camera is mounted high it can miss them.
- Dust kills the charge. Cement and dust from the site settle on the solar panel, so the camera stops charging and switches off.
- Running costs. The battery needs replacing once a year, and the SIM card inside must be recharged every month, even if you have internet at home.
- No use later. After the house is built, a solar camera is of little use to you.
A better plan for CCTV for construction site security: use two of your final cameras
You will fit cameras around the finished house anyway. So buy two of them now, fix them at the site, and move them to the house when it is done. Nothing is wasted. They also record for 24 hours a day, not only on motion.
- Aim the first camera at the place where iron rods and materials are stored.
- Aim the second at the area where the construction work is going on.
AI features that suit a building site
We install Stanklin, a Taiwan-based AI CCTV brand, for this job:
- Human detection with alarm. Mark the area around the rods; if someone comes to steal, the camera sounds the alarm and can play a voice warning to drive them away.
- Big speaker. Talk live to the mason or workers on site from your phone, for example to ask whether the curing water has been poured.
- Face detection. The camera photographs the face of everyone who comes and sends the photos to your phone. If 10 people visited, you see the 10 photos at a glance and need not scroll through 24 hours of video.
- For CCTV for construction site protection, solar cameras can switch off, miss people and clog with dust at a construction site.
- Two wired cameras you can reuse at home protect the site and cost nothing extra later.
- Human detection, alarm, speaker and face lists make the site far harder to rob.
After the house is built: reuse the CCTV from the construction site
Unscrew the two cameras and fix them at the house. Then add two or three more cameras and the CCTV work is finished. If you are still building, plan the pipes for those cameras before the roof is cast; our roof concrete wiring guide explains where.
Key takeaways
Frequently asked questions
Why do solar CCTV cameras fail on construction sites?
They can switch off at night, record only on motion, stop charging when covered in dust, and need yearly battery changes and monthly SIM recharges.
Which cameras should I use at a house under construction?
The same cameras you will use at the finished house, moved to the house after the work is complete.
Can I talk to workers through the camera?
Yes. A large speaker lets you speak live to people at the site from your phone.
How do I see who came to the site?
Face detection lists the faces of visitors and sends the photos to your phone.
