Product Overview
Compact wall-mounted power supplies are a practical necessity when connecting HDTVI cameras, access control panels, or other 12V DC-powered security devices without running power from a central unit. The 12V DC 2500mA SM PSU Plug Pack (30G) is a switch mode power supply unit designed to deliver a stable 12V DC output at up to 2500mA, with a maximum output power of 30W. Featuring a wide 90V-264V AC input voltage range, it accommodates variable mains conditions and is suited to Australian installations. The active and neutral pins meet AS/NZS3112 for electrical safety compliance. Measuring 55(w) x 96(h) x 42(d)mm, it is a lightweight and compact unit designed for wall outlet mounting. Note that the 30G series housing width differs from narrower models in the same range and may not allow 2 units to sit side by side in a standard double power outlet.
Key Capabilities
12V DC / 2500mA Output
Delivers a stable 12V DC supply at 2500mA, suitable for powering HDTVI cameras and other 12V security devices that draw within the 30W maximum output rating.
Wide AC Input Range
Accepts 90V-264V AC input, making this unit compatible with variable mains supply conditions and suitable for installations across different environments where supply voltage may fluctuate.
AS/NZS3112 Compliance
Insulated active and neutral pins meet the Australian and New Zealand AS/NZS3112 standard for electrical safety, important for installations that must satisfy local compliance requirements.
Compact Switch Mode Design
Switch mode technology provides efficient power conversion in a lightweight housing measuring 55(w) x 96(h) x 42(d)mm, keeping the unit small enough for wall outlet use without adding bulk to the installation.
Best For
- Individual Camera Power: Supplying a dedicated 12V DC feed to a single HDTVI camera where a central power distribution unit is not used or is not practical.
- Hikvision TVI Camera Installations: Providing a compliant, correctly rated power source for Hikvision HDTVI cameras in the 5MP and 8MP TVI 4.0 range that require 12V DC operation.
- Locations Without Structured Power Runs: Installations where running power cabling back to a central supply is impractical, and a wall outlet near the camera position is available.
Why Choose the 12V DC 2500mA SM PSU Plug Pack (30G)
Where a central power distribution board is not part of the installation plan, this plug pack provides a self-contained 12V DC supply rated to 30W maximum output, eliminating the need to run power cabling over long distances back to a rack or cabinet. The wide 90V-264V AC input range means the unit is not sensitive to minor mains supply variation, which is a practical consideration in older commercial and residential buildings. The AS/NZS3112 compliant pin design ensures the unit meets Australian electrical safety expectations. At 2500mA output, it delivers enough current for a single HDTVI camera and, in some cases, a short cable run with additional load. Available through Security Wholesalers as part of the accessories range, the T1225-21G is a straightforward component for installers who need a reliable local power source for individual camera positions.
Buyer Decision Tips
Check Your Camera’s Power Draw: Before using this plug pack, confirm the total current draw of the camera and any connected accessories does not exceed 2500mA (2.5A) at 12V DC. The unit’s 30W maximum output provides a ceiling, and exceeding it risks supply instability. For cameras that include IR LEDs, motorised lenses, or built-in heating elements, check the manufacturer’s maximum current specification rather than the typical operating figure.

Ideal Use Cases
HDTVI Camera at a Remote Position
Where a Hikvision TVI camera is positioned away from a central cabinet and a power outlet is nearby, this plug pack provides a self-contained 12V DC feed without needing a separate power run.
Small Standalone CCTV Installations
For simple 1-2 camera setups where a full power distribution board is unnecessary, individual plug packs at each camera location keep the installation straightforward and cost-effective.
Camera Replacement or Upgrade Work
When swapping out a failed or outdated camera, this plug pack can replace an existing local power supply at the outlet, matching the 12V DC requirement of most HDTVI camera models.
Temporary or Portable Security Setups
The wide 90V-264V AC input range and compact size make this unit practical for temporary camera installations or situations where the mains supply is not from a fixed, well-regulated source.
Choosing the Right Model
- Choose this model if: Your camera or device requires a 12V DC supply and draws no more than 2500mA (2.5A), and you need a compact AS/NZS3112 compliant wall-mounted plug pack for a single local power point.
- Choose a different model if: You need to power multiple cameras from a single supply – a 12V DC multi-output power distribution board would be more appropriate. If your camera requires a higher current than 2500mA or a different output voltage, select a power supply rated to match those specifications.
FAQs
- What does the 30G designation mean for this plug pack?
The 30G refers to the series of this switch mode power supply unit. The 30G housing is wider than narrower models in the same range, which means 2 units of this model cannot typically be placed side by side in a standard double power outlet. If you need 2 plug packs in the same double outlet, check whether a narrower series model meets your current requirements.
- Is this plug pack suitable for Hikvision TVI 4.0 cameras?
Yes. The T1225-21G is listed under Hikvision HDTVI and TVI 4.0 accessories and provides 12V DC at 2500mA, which is compatible with Hikvision HDTVI cameras that operate within that current draw. Always verify the specific camera’s maximum current consumption before connecting.
- Does the wide input voltage range (90V-264V AC) offer any practical benefit in Australian installations?
Australian mains voltage is nominally 230V AC but can vary. The 90V-264V input range means this switch mode supply handles fluctuations without instability, making it suitable for locations where supply quality is inconsistent, such as rural properties or older commercial buildings.
- Can I use this plug pack to power more than 1 camera?
This unit provides a single 12V DC output at 2500mA. Powering multiple cameras from one supply requires a multi-output power distribution unit. Attempting to draw current beyond the 2500mA or 30W maximum from this plug pack risks supply instability or damage to connected equipment.
- Where can I find this plug pack and confirm it suits my installation?
The T1225-21G is available through Security Wholesalers as part of the CCTV accessories range. If you are unsure whether this supply matches your camera’s power requirements, check the camera’s datasheet for its maximum current draw at 12V DC before ordering.
