Steps to install a commercial alarm system

Needs analysis

The first step is to analyze your company’s specific needs. Identify critical areas requiring surveillance, such as entrances, exits, storage areas and high-risk zones. This assessment will help you determine the number of sensors, cameras and motion detectors required.

The needs analysis is a crucial step in the installation of a commercial alarm system, as it helps determine the specific security features required to effectively protect company premises. This analysis is based on a number of methodical steps designed to identify risks, define sensitive areas, and select appropriate security solutions. Here are the main steps involved in carrying out a needs analysis:

1. Risk assessment

Risk assessment is the first step in a needs analysis. It consists in identifying potential threats to which the company could be exposed, such as :

  • Intrusions and burglaries: Assess vulnerable points of entry such as doors, windows and unguarded access.
  • Vandalism: Identify outdoor areas that may be prone to vandalism, such as parking lots and warehouses.
  • Unauthorized access: Control access to sensitive areas such as server rooms, data storage areas or executive offices.

The risk assessment should include a physical inspection of the premises and, if possible, a historical analysis of previous security incidents.

2. Identification of critical areas

By identifying critical areas, you can pinpoint the most vulnerable spots and decide where to install safety devices:

  • Entrances and exits: Main and secondary doors often require motion sensors, door detectors and cameras.
  • Sensitive rooms: Server rooms, executive offices and data storage areas must be equipped with access control systems.
  • Public areas: Areas such as lobbies and corridors should be monitored by cameras to prevent suspicious behavior.

3. Video surveillance needs assessment

It’s important to determine where to place the surveillance cameras to cover the maximum number of areas without blind spots. You need to take into account :

  • Field of vision: Choose locations that offer a wide, clear view of the areas to be monitored.
  • Lighting conditions: Install cameras adapted to lighting conditions (day/night) and to indoor and outdoor spaces.

This evaluation allows you to define the type of camera to be used, such as fixed, dome or PTZ (Pan, Tilt, Zoom).

4. Identification of access points

The analysis should include all possible access points, including doors, windows and service accesses (such as garage doors or maintenance accesses). Each access point should be secured with door or window sensors.

5. Definition of motion detection requirements

Identifying areas where motion needs to be detected is crucial to preventing intrusions. Motion detectors should be positioned in corridors, staircases and open spaces where there is little after-hours traffic.

6. Access control needs assessment

If certain areas require restricted access, such as storage rooms for confidential documents, access control systems such as card readers, keypads or biometric readers are recommended.

7. Environmental considerations

The analysis must also take into account the company’s environment, in particular :

  • Weather conditions: Outdoor equipment must be weather-resistant.
  • Interference: Identify potential sources of interference (electromagnetic or radio) that could affect the operation of wireless sensors and systems.

8. Analysis of legal and regulatory requirements

The company must comply with local regulations and safety standards. This may include obligations regarding the confidentiality of data recorded by surveillance cameras, mandatory signage of monitored areas, and safety standards for electrical installations.

9. Assessment of communication and warning needs

The analysis must also take into account how alerts will be transmitted in the event of an incident:

  • Local alerts: Sirens and flashing lights on site.
  • Remote alerts: Notifications sent to smartphones, tablets or directly to a monitoring company.

10. Employee and stakeholder consultation

Involving employees and stakeholders in the process provides a better understanding of day-to-day risks and the specific needs of each department. It also helps ensure staff buy-in to the new safety measures.

11. Analysis report and recommendations

Once all the data has been collected, an analysis report must be drawn up, detailing the needs identified, security recommendations, and a proposal for the installation of a commercial alarm system tailored to the company’s specific requirements.


By carrying out a complete needs analysis, you can be sure that the commercial alarm system you choose will be effective, tailored to your company’s specific risks, and will contribute to optimum protection of premises and employees.

Choosing a commercial alarm system

After analyzing your needs, choose the commercial alarm system that best suits your business. Options include wired, wireless and hybrid systems. Each has its own specific features, and the choice will depend on your security needs, budget and premises configuration.

Wired installation

Wired installation is ideal for large companies with complex infrastructures. It requires physical wiring between each component and the alarm control panel.

Advantages :

  • Greater reliability: less risk of interference or malfunction.
  • Enhanced security: harder to hack or disable.

Disadvantages :

  • High installation cost: often requires major work, such as drilling into walls.
  • Limited flexibility: components are difficult to move once installed.

Wireless installation

Wireless alarm systems use radio signals to communicate between components, making them easy to install.

Advantages :

  • Quick installation: no need for cables, reducing installation time and costs.
  • Highly flexible: easy to reconfigure and relocate.

Disadvantages :

  • Possible interference: Signals may be interfered with by other electronic devices.
  • Technology-dependent security: wireless systems can be vulnerable to hacking if not properly secured.

Hybrid installation

Hybrid systems combine wired and wireless elements, offering a balance between security and flexibility.

Advantages :

  • Security and flexibility: Enjoy the benefits of both methods.
  • Adaptability: Can be adjusted to specific company needs.

Disadvantages :

  • Intermediate cost: more expensive than wireless, but less than wired.
  • Complex configuration: requires good management of both technologies.

Component installation

The installation of a commercial alarm system involves several components:

  • Alarm control center: the brain of the system, coordinating sensors and cameras.
  • Motion detectors: detect suspicious movements in protected areas.
  • Door and window sensors: monitor entry points.
  • Surveillance cameras: record and transmit images in real time.
  • Sirens: alert in the event of intrusion.

Each component must be installed in accordance with the manufacturer’s specifications, respecting safety and wiring rules (for wired systems).

Configuration and testing

Once the physical installation is complete, configure the alarm system by programming zones, monitoring schedules and sensor sensitivity levels. Test the system to make sure it’s working properly, with intruder simulations to check alarm responsiveness.
