Security Power Supplies

Security Power Supplies for CCTV, Alarm and Access Control Systems

A camera that keeps dropping out or an alarm panel throwing a false AC fail alert is often a power supply problem, not a wiring fault. Security power supplies regulate and distribute 12V or 24V output to cameras, NVRs, alarm panels and access readers, and matching the right amperage — from a compact 12V DC 1.5A CCTV plug pack to a rack unit — keeps an install stable. See our guide on CCTV power supply sizing for more.

What's in This Range

• 12V DC monitored alarm panel power supply — regulated output with AC fail and low battery terminals for compliant installs.
• 8A 1RU rack-mount power supply — fused, LED-indicated outputs for racks running several cameras or an NVR.
• 32-way wall-mount PSU with battery backup — fused, LED voltage display, high-capacity distribution for larger installs.
• Hikvision K7P02 access control power supply — purpose-built supply for door controllers and access hardware.
• 10-way power distribution module — splits one 12VDC/24VAC source across multiple devices from a single enclosure.
• Ajax NVR power supply — low-voltage supply built for Ajax NVR installations.

Who Uses This

Security installers, alarm technicians and access control integrators reach for this range on commercial fit-outs, warehouse and retail refurbishments, and switchboard or comms cabinet upgrades where a panel, NVR or reader needs a dedicated, monitored supply rather than a shared power point.

Security Power Supplies — Common Questions

What amperage power supply do I need for a CCTV or alarm system?

It depends on how many devices draw from the one supply. A single camera or reader is fine on 1–1.5A, but panels feeding several devices need more headroom — an adjustable 5A PSU with surge protection gives room to add outputs later, while larger installs suit a rack-mount or 32-way distribution unit.

Do security power supplies need battery backup?

For alarm panels and access control, yes — most compliance-focused installs pair the main PSU with a sealed lead-acid battery so the panel keeps operating through a mains outage. A 3A PSU with SLA battery charger and LED status handles the charging automatically, and AC fail monitoring flags a fault before the battery drops out.

Can one power supply run multiple cameras or devices?

Yes, provided total current draw stays within the rated output — this is what power distribution modules are built for, splitting one regulated source across several fused outputs instead of separate adapters. Our guide on CCTV power distribution covers sizing a shared supply.
