Low-voltage systems and video surveillance

Low-voltage systems connect everything: workstations, cameras, badge readers, public address, intercom and fire detection. You notice them the day they fail: a camera switched off for weeks, a recording that cannot be found, a former employee's badge still active.

SADIS, a Moroccan company based in Laâyoune and Casablanca, designs, deploys and maintains these installations, from cabling to applications. This activity falls under its infrastructure division, presented on the our divisions page.

Structured cabling

Cameras, badges, Wi-Fi access points and phones all run over the same physical network. Improvised cabling weakens every addition. Structured cabling is designed as a lasting installation:

• Category 6 and 6A copper for workstations and network-powered equipment, each outlet labelled.
• Single-mode or multimode fibre optics between buildings, floors or the warehouse, where copper reaches its limits.
• Orderly 19-inch racks: patching, switches and recorders neatly arranged, cables labelled, power protected.
• Link acceptance testing: every link is tested and the result recorded.

Public address, intercom and fire detection are integrated into the same plan. Switching, VLANs and Wi-Fi are detailed on the network and infrastructure page.

Business video surveillance

A video surveillance installation is judged by one question: does the image show what you need on the day you look for it? Everything therefore starts with a placement study.

• Sensitive points: entrances, loading docks, till, high-value stock, car park, technical room.
• Fields of view: what each camera covers and what it must make it possible to identify.
• Lighting: backlight, dark areas, differences between day and night.
• The camera plan, approved before installation.

This study avoids two common defects: cameras filming walls, and key areas left uncovered.

IP cameras and mobile playback

IP cameras are powered over the network (PoE): a single cable carries both the image and the power. The ONVIF standard makes it possible to combine several brands. SADIS works in particular with Hikvision, Dahua and Axis, without being an authorised reseller: equipment is chosen to suit the site.

• NVR recorder or video management software (VMS), sized according to the number of cameras and the retention period.
• Live view and playback on desktop and mobile, for the site manager as well as for management.
• Per-user permissions: who can view, who can play back, who can export.

A recorder exposed on the Internet with its original password is an open door. Remote access is secured like the rest of the information system, a subject covered on the cybersecurity page.

Law 09-08 and the CNDP

Video surveillance processes personal data within the meaning of Law 09-08. People being filmed must be informed. Formalities with the CNDP may be required depending on the case; it is up to each company to check them with the Commission.

The image retention period is set in advance, proportionate to the purpose. It determines the storage capacity. Biometrics also fall under data protection: the choice between badges and biometrics is made with management.

Access control and time tracking

Access control answers what keys cannot: who enters, where and at what time.

• RFID badge or biometrics, with equipment such as ZKTeco: permissions by zone and by time slot, a lost badge deleted immediately.
• Intrusion detection: detection outside opening hours, in addition to the cameras.
• Attendance time management: recorded entries and exits replace the sign-in sheet.

What you receive

• The as-built documentation (DOE), with cabling plans and diagrams.
• The camera placement plan and the security system diagram.
• The labelling register and the operating documentation.
• The configuration sheet: retention period, accounts and permissions.
• The joint acceptance report, drawn up with you.
• User training in playing back and exporting footage.

Administrator accounts are handed over to your company: you remain in control of your installation.

Works without disruption

Works are carried out in the evening and at the weekend if necessary, and the cutover is prepared to limit disruption. Two anonymised references:

• Distribution and logistics: network for a new head office with warehouse, more than 1,500 m² covered, three sites connected by VPN.
• Subsidiary of a French group: air-conditioned technical room, 900 m of structured cabling, network and Microsoft 365, actual bandwidth raised from 2 to 60 Mb/s, works carried out at the weekend with no interruption to business.

Names and contacts shared in a meeting, with the clients' agreement. Other projects are listed on the references page.

Maintenance and commitments

A dirty lens or a full disk gives no warning. Scheduled preventive visits check lenses, recordings and disk space, with a written report. Under contract, during business hours:

• Acknowledgement of any request within 24 business hours.
• Remote intervention in under one hour.
• On-site intervention in under 4 hours in and around Casablanca, 48 hours outside Casablanca, under 12 hours in an emergency.
• 12-month SADIS warranty on turnkey projects, with the manufacturer's warranty applying depending on the equipment.

Fleet follow-up is described on the IT fleet maintenance page.

How a project unfolds

1. Free on-site audit: survey of the existing setup and the need. It comes before any quote.
2. Costing based on plans: no work begins without a signed approval.
3. Deployment: installation, connection and configuration.
4. Acceptance and handover: DOE, configuration sheet and training.
5. Maintenance under contract, if you wish.

Frequently asked questions

Can we keep some of our current cameras?

Often, yes. The audit identifies reusable equipment, and ONVIF cameras can generally be integrated with a new recorder.

Will we be able to view the cameras from a phone?

Yes, live and in playback, with per-user permissions and secure remote access.

How long are the images kept?

The period is defined with you, proportionate to the purpose, then recorded in the configuration sheet.

Do we need to make a declaration to install cameras?

People being filmed must be informed, and formalities with the CNDP may be required under Law 09-08. SADIS does not provide legal advice: check your situation with the CNDP.

Can access control be used for time tracking?

Yes. Recorded entries and exits serve as the basis for attendance time management.
