What does ATEL Technologies do?
ATEL Technologies is a San Diego low voltage, security and IT contractor founded in 1985. It designs, installs and supports structured cabling and fiber, security cameras, access control, audio video, life safety communications such as ERRCS and area of refuge systems, business internet, phone and cloud services, and managed and co-managed IT for businesses across San Diego County, and keeps them running with ongoing support plans.
What is a low voltage contractor?
A low voltage contractor installs systems that run on low-voltage power and data cabling rather than standard electrical circuits: network and fiber cabling, Wi-Fi, security cameras, access control, intercoms, audio video, paging, and life safety communications. In California this work is licensed under the C-7 Low Voltage Systems classification. ATEL holds C-7 and C-10 Electrical licenses (CSLB #1121116).
Why use one partner for cabling, security, AV and IT?
Cameras, access control, phones, AV and computers all run on the same cabling and network. One partner designs them together, coordinates one schedule, supports them after installation, and takes responsibility when something fails, instead of separate vendors blaming each other.
What areas does ATEL Technologies serve?
ATEL is based in Miramar, San Diego at 9580 Black Mountain Rd, Suite A, and serves businesses throughout San Diego County.
Does ATEL work on new construction and tenant improvements?
Yes. ATEL provides the full low voltage scope for new construction, tenant improvements and office moves, including cabling, MDF/IDF rooms, Wi-Fi, cameras, access control, AV, ERRCS and area of refuge systems, and coordinates with general contractors and inspectors.
Which brands does ATEL install?
ATEL is vendor-neutral. For video surveillance it installs Verkada, Axis, Bosch, Avigilon, IC Realtime, Alibi Security, Uniview and Eagle Eye Networks; for access control ProdataKey (PDK io), Brivo, Verkada, LenelS2, dormakaba, LiftMaster, DoorKing and MyDoorView; for networking, Wi-Fi and security Cisco, HPE, Ubiquiti, RUCKUS and SonicWall; and for IT infrastructure Nutanix and Scale Computing. For internet, voice and cloud services ATEL compares 400+ providers.
Does ATEL offer ongoing support after installation?
Yes. ATEL offers support plans for the security systems it installs (cameras, access control, intercoms and alarms) that cover normal wear and tear, updates and 24-hour emergency response; flat-rate managed and co-managed IT; and ongoing management of internet, phone and cloud services, including outages, moves, billing disputes and renewals. Ask about a support plan.
