Delta-M designs, installs and maintains complete security systems — video surveillance, alarms, access control and intercoms — for homeowners and businesses in Bouches-du-Rhône and across the PACA region. We work with market-leading brands: Dahua and Hikvision for video surveillance, Ajax and Risco for residential alarms, and Dahua and Vanderbilt for large-scale professional installations.
Next-generation video surveillance: AI working for your security
The cameras we install no longer just record — they analyse the scene in real time using onboard artificial intelligence.
Dahua WizSense uses a deep-learning algorithm and a dedicated AI chip to automatically distinguish a person or vehicle from irrelevant motion (foliage, shadows, animals), which greatly reduces false alerts. This range also includes line-crossing detection, perimeter intrusion detection, facial recognition, and AI SSA technology that automatically adjusts camera settings to the scene’s conditions.
Hikvision AcuSense works on the same principle: deep-learning algorithms built into the cameras and recorders precisely detect humans and vehicles, send instant smartphone notifications, and automatically tag recordings. The DeepinMind / DeepinView range goes further with business-grade features such as licence-plate recognition and people counting, useful for professional and commercial sites.
The practical result for you: fewer false alerts, more relevant notifications, and instant video search when you need it.
Connected security: video surveillance, alarm, access control and intercom working together
Installing several devices that don’t talk to each other limits their effectiveness. We favour ecosystems where video surveillance, alarms, access control and intercoms communicate on the same interface:
a triggered alarm can automatically activate the relevant cameras and lock access points;
a badge used at an unusual time can trigger a real-time video check;
video intercom lets you identify a visitor and unlock access from a smartphone.
This unified approach simplifies day-to-day management while improving response time in the event of an incident.
For the home: Ajax and Risco solutions
Ajax Systems offers a broad range (60+ devices, wireless Jeweller and wired Fibra versions) with a range of up to 2 km between the hub and detectors, 4 to 7 years of battery life depending on the sensor, a backup GSM connection in case of internet outage, and an easy-to-use mobile app. The system works without a mandatory subscription and is certified EN 50131 Grade 2/3 and NF A2P.
Risco offers modular control panels such as the Agility, an NF A2P-certified two-way wireless alarm, or the LightSYS2 for larger needs. Motion detectors, glass-break sensors, door/window contacts and outdoor sirens are controlled via Wi-Fi, GSM or Ethernet, with real-time alerts on the mobile app.
Note: for sites already equipped with a Ubiquiti UniFi network, UniFi Protect video surveillance integrates natively into the same network ecosystem (see our Wi-Fi & network page) — local recording with no cloud subscription, centralised management alongside your access points and access control, all on a single interface.
For businesses: Dahua and Vanderbilt for large sites
For professional sites — shops, offices, industrial sites, co-owned buildings (see also our Access control & intercom page) — professional-grade Dahua video surveillance combines with Vanderbilt access control solutions, designed for organisations of any size.
Vanderbilt offers IP door controllers (1, 2 or 4 doors), compatible with most badge technologies, and scalable systems capable of managing from 100 to over 2,500 users with access rights differentiated by time slot and by zone.
Why choose Delta-M
We assess your site, size the right solution (residential or professional), and handle the installation as well as ongoing support. Our role: to guide you toward the equipment that actually fits your needs — not the most expensive one.
Frequently asked questions
What is AI-powered video surveillance?
It’s a camera capable of analysing the image itself to distinguish a person or vehicle from irrelevant motion, reducing false alerts and speeding up event search in recordings.
Ajax or Risco: which alarm should I choose for my home?
Both are NF A2P-certified and designed for residential use. The choice mainly depends on your home’s layout and your usage preferences — we advise you after an on-site assessment.
Can alarm, cameras and access control be linked in a single app?
Yes — that’s precisely the benefit of the integrated ecosystems we install: an alarm, video and access system that communicate with each other from a single interface.
Is Vanderbilt suitable for a small business?
Yes, Vanderbilt controllers are scalable and sized just as well for a small structure as for a site with several thousand users.
