Isolated camera network
VLAN, firewall rules and no direct exposure to the internet.
In the office buildings along Kifisias Avenue, cameras have to fit the building's rules, the company's IT policies and GDPR. We design them as part of the network, not as a separate box in the corner.
CCTV installation in Marousi is mostly about office floors in multi-tenant buildings along Kifisias Avenue, in Paradisos and Agios Thomas. The building usually already has cameras at the entrance, in the lobby and in the car park, owned by building management. Your responsibility starts at your floor's door.
That changes the design. You do not need to film the lobby again. You need cameras at the floor entrance, at reception, in the rack room and in storerooms with equipment or samples. Before anything else we ask building management for their rules on ceiling work and access hours.
Kifisias Avenue starts in Ampelokipi, right by our office, so visits to Marousi are easy to arrange. We often schedule the work for an afternoon or a Saturday, when the floor is empty.

In group subsidiaries and companies with their own IT, the first question is not camera resolution. It is where the camera connects and what it can reach on the network. IP cameras are computers with a lens, and on the same network as workstations they become an easy target.
So we put the cameras and the NVR on a separate VLAN, block their traffic to the internet where it is not needed and disable the manufacturers' P2P cloud services. Remote viewing goes through the company VPN.
In open-plan offices there is often a temptation to fit one camera that sees the whole floor. The Data Protection Authority does not allow that without a serious reason: cameras must not monitor employees' performance and do not go in kitchens or rest areas. Staff are informed in writing before the system goes live.
We recommend cameras at entry points and in areas holding valuables, not in meeting rooms. Audio is never recorded. In larger companies we work with your data protection officer or legal adviser, because we are not lawyers and the final responsibility lies with the company.
Many companies in Marousi already use cards for the building entrance. For the floor we add access control at reception, the server room and the archive, and link the events to the cameras. When a door opens out of hours, you see the matching clip straight away.
When staff leave, this pays off: the card is disabled once and the user's camera account is closed the same day.
Around the large shopping centres and in central Marousi there are shops and showrooms. Inside a shopping centre its own rules on works and cabling apply, and we usually do the job before opening. In medical centres near the hospitals, cameras cover the entrance and waiting area, never consulting rooms.
In Pefki, Lykovrysi and Melissia demand comes from small shops and detached houses. Four cameras and a small NVR are often enough there, with a phone app and alerts only for people and vehicles.
VLAN, firewall rules and no direct exposure to the internet.
We talk to management about ceilings, working hours and common areas.
Access control is linked to the cameras, so every event comes with a clip.
Devices, passwords, network diagram, deletion settings and signs.
Who watches live, who exports a clip, who changes settings.
We learn your IT policies, the building rules and what the building's own cameras already cover.
Using a floor plan or drawings, we set positions, views and routes through the ceiling.
Equipment, network design, retention settings and sign positions, ready for approval.
We work when the floor is empty, so staff are not disturbed.
We hand over passwords, accounts and the documentation pack, and give a short training to those who will use the system.
