Low Voltage & Security Systems
STP designs and installs low-voltage building systems in Armenia: video surveillance, access control, and intrusion and fire alarm systems including wireless, and the European-standard distribution boards that power them. All of it goes onto the same documented infrastructure as your data network.
Overview
Low-voltage systems are usually bought separately from IT, by a different budget holder, and installed by a different contractor. The result is a building with four parallel cable plants, four support numbers, and no one able to say why the cameras drop out when the alarm panel is serviced.
Because we install the structured cabling as well, we can put surveillance, access control and alarm systems onto one properly designed, properly documented infrastructure: with one contractor accountable when something stops working.
Wireless alarm systems matter where you cannot run cable: heritage buildings, live retail floors, and phased fit-outs where the walls are already closed. We treat wireless as a deliberate design choice with a stated battery and supervision regime, not a shortcut.
Security systems are only as available as the power behind them. We build distribution boards to the European standard EN 61439, with circuit breakers to EN 60898-1, residual current devices to EN 61008-1 and surge protection to EN 61643-11, and an automatic transfer switch that moves the load to a generator when mains power fails. Cameras, recorders, access control, alarms and the network rack each get their own protected circuit, so one fault does not take the building's security down with it.
What is included
- IP video surveillance design, installation and commissioning
- Camera placement modelling for real coverage, not nominal count
- Network video recorder sizing, retention and storage planning
- Access control: readers, controllers, door hardware integration
- Intrusion alarm systems, wired and wireless
- Fire alarm system cabling and device installation
- Perimeter detection
- Integration with the corporate network, including VLAN segmentation
- Remote monitoring and alerting configuration
- Handover documentation and operator training
- Electrical distribution boards built to EN 61439
- Automatic transfer switching between mains and generator
- Circuit breakers, residual current devices and surge protection
- A dedicated protected circuit for each security system and the network rack
What you get out of it
- One accountable contractor across data, voice, video and alarms
- Security systems segmented from corporate traffic by design
- Coverage you can verify against a plan, not a promise

Questions
- Can security cameras share the corporate network?
- They can, but they should be segmented onto their own VLAN with controlled routing. Surveillance devices are among the least-patched equipment in most buildings, so they are treated as untrusted and isolated: while still being centrally monitored.
- Do you install wireless alarm systems?
- Yes, including in buildings where cable routes are not available. Wireless devices are specified with a defined supervision interval and battery replacement schedule, both documented at handover.
- Do you also build the electrical distribution board?
- Yes. We design and build distribution boards to EN 61439, with an automatic transfer switch to a generator where the systems must keep running through a mains failure, and a protected circuit for each system so that a fault on one does not trip the others.
