Alarms and video surveillance for businesses in Nice and the Alpes-Maritimes

Intruder alarms, video surveillance and access control protect three different things: the building while it is closed, the record of what happened during an incident, and the day-to-day management of who comes in. MZ Informatique installs them and wires them into your network in Nice, Sophia Antipolis, Cannes and Monaco, within GDPR rules — and treats cameras as what they really are: connected equipment to be secured exactly like your workstations.

Alarms, video surveillance, access control: which equipment for which risk?

The three answer different questions, and they are rarely combined at random. An intruder alarm detects an unauthorised entry and triggers a response: siren, notification, verification. It protects the hours when the premises are closed. Video surveillance prevents nothing on its own: it deters, it records, and it provides usable footage after the event. Access control handles the everyday: who comes in, where, at what times, and it lets you withdraw an access right in seconds when a badge is lost or an employee leaves.

For a shop in Nice, video and an alarm are usually the priority. For a practice or a design office in Sophia Antipolis holding sensitive data, access control on the technical rooms matters more. We start from the real risk and from the floor plan, not from a catalogue.

  • Intruder alarm: detection, siren, notification and verification.
  • Video surveillance: deterrence, evidence and footage that is usable after an incident.
  • Access control: badges, time windows, immediate withdrawal of an entry right.

How does an installation work?

In four stages, and it always starts with a visit. Site visit: a survey of the entrances, the blind spots, the areas that must not be filmed, the power points and the existing cable routes. Layout plan: the number and position of cameras, detectors and readers, stating for each camera what it sees and what it does not. Installation: cabling, mounting, connection to your network and to the power supply, with the recorder placed in a locked room. Handover: access configured, the authorised people trained, and written documentation.

The cabling follows the same rules as the rest of your infrastructure: clean routes, labelled links, terminated in the cabinet. That is also what makes the installation repairable years later, by us or by somebody else.

Video surveillance and the GDPR: what does the law require?

Filming people is processing of personal data: it follows precise rules, and a non-compliant installation is also one whose footage will be unusable. Four obligations come up every time. Inform the people being filmed with a visible sign at every entrance to a monitored area, and inform employees individually. Consult the works council before the system goes live, where one exists. Record the system in the register of processing activities, with its purpose, its retention period and the list of people authorised to view the footage. Limit the field of view: no camera permanently trained on a workstation, nor on break areas, changing rooms or union offices.

Where cameras film a space open to the public, a prefectural authorisation is required as well. We prepare these elements with you and hand you the written file: without it, the installation is a legal risk as much as a security tool.

Applicable framework: the GDPR, the French labour code (information and consultation), the French internal security code for spaces open to the public, and the CNIL guidance on video surveillance in the workplace. To be validated by your own legal adviser before the system goes live.

Why give cameras and IT to the same supplier?

Because an IP camera is a computer sitting on your network. Shipped with a default password, firmware that is never updated and an admin interface sometimes reachable from the internet, it becomes exactly the kind of open door we spend our days closing for our clients. We have seen video surveillance installations used as the foothold for an intrusion onto the office network.

So we treat cameras, the recorder and the badge readers like the rest of the estate: a dedicated network kept separate from the office network, passwords changed and recorded, firmware kept up to date, remote access closed by default and opened only through an encrypted channel, and a recorder that is physically out of reach. That is the crossover no general installer makes, and it is why this service belongs in our cybersecurity silo.

  • A dedicated network for the cameras, separate from the office network.
  • Default passwords changed and recorded, named accounts for viewing footage.
  • Firmware on the cameras and the recorder tracked and kept up to date.
  • No admin interface exposed directly to the internet.

How much does an alarm or video surveillance installation cost?

The budget depends on the number of points to cover, on the length of cabling and on the nature of the premises — an open-plan office is not handled like a warehouse or a ground-floor shop. The costing is set out on the quotation, drawn up after the site visit: costing a security installation without having been on site makes no sense.

The visit and the layout plan are included in the free audit when the request comes alongside IT security work. You leave with the number of cameras actually needed — often fewer than the number you were offered elsewhere.

Maintaining the installation can be folded into the monthly monitoring retainer, with equipment updates and periodic checks that the recordings are being kept.

Frequently asked questions

Alarms and video surveillance: what we get asked

Can you film employees at their workstations?

No. A camera cannot be permanently trained on a workstation, nor on break areas, changing rooms or union offices. Surveillance has to be proportionate to the stated purpose: protecting property, stock or sensitive entrances. We settle that point at the site visit, before proposing any layout.

Will you take over an existing installation?

Yes, and it starts with an assessment: the equipment in place, the state of the cabling, the network configuration, passwords still left at their defaults, firmware, and the retention period actually configured. We then tell you honestly what is worth keeping and what has to be replaced, rather than ripping everything out on principle.

Can the footage be viewed remotely?

Yes, but never by exposing the recorder directly to the internet. Remote access goes through an encrypted channel, with named accounts and two-factor authentication: it is the only way to stop a system meant to protect you from becoming the way into your IT.

Do you work in Cannes, Antibes and Monaco?

Yes. We travel to Nice, Sophia Antipolis, Cannes, Antibes, Grasse, Menton and Monaco for the site visit as well as for the installation and the maintenance. The preliminary visit is always required: costing a security installation remotely makes no sense.

Do you need cameras, an alarm, or something else?

A free site visit in Nice, Sophia Antipolis, Cannes or Monaco, and a written layout plan. You will know what is needed, and what is not.
