Real HD 18 Port 20 Amp High Power Security CCTV Camera Access Control Power Distribution Box (12V DC, PTC Protected)
Quick take
This Real HD power distribution box is built to supply 12V DC to multiple security cameras from one 100-240V AC input. It includes a metal enclosure with a key lock, plus per-port auto-reset PTC protection and individual power status LEDs. The main buying caveat is power budgeting: each port is limited to 1A, and the included DC male pigtails are short, so some installs may require your own wiring plan.
Pros and cons
Pros
- Centralized 18-port 12V DC output for running multiple CCTV-style devices
- Per-port auto-reset PTC protection designed to prevent “blown” fuses and isolate issues by channel
- Key-locked metal case for basic security against unauthorized access
- LED indicators for monitoring AC/DC power status per the front panel design
Cons
- Port limit matters, each output port is rated for up to 1A (not all 12V devices can share a port safely)
- Included DC male pigtail leads are short, which may complicate neat pre-wiring or retrofits
What buyers think
Buyer-review evidence is limited in detail, but the available feedback is broadly consistent on two themes. First, it’s used successfully as a replacement or supplementary power panel, with buyers noting it works as intended for powering cameras. Second, practical install considerations come up, especially around the included pigtails, which some users found too short for their specific wiring approach. Overall, reviewers tend to treat this as a functional multi-output power supply solution, with the biggest day-to-day variable being whether the port limit and lead length fit the way you are installing cameras.
How this power distribution box is designed to work
This unit takes a single AC input (100-240V AC, 50/60Hz) and distributes 12V DC power across 18 separate output channels intended for CCTV and related low-voltage devices. Each channel has individual PTC output protection, which is meant to handle overcurrent situations without a permanent failure, and each port also has status visibility via LEDs.
Key specs to know before you buy
- Outputs: 18 channels of 12V DC
- Total output capacity: up to 20A total output (with each port limited to 1A)
- Protection: individual auto-reset PTC fuses per output
- Enclosure: metal case with key lock
- Input: 100-240V AC, 4A, 50/60Hz
Pros and cons for real installations
Who it’s best for
- Home and small business setups that want one centralized 12V DC distribution panel for multiple cameras
- Buyers replacing an older multi-port CCTV power distribution unit
- Installers who value per-port protection and want channel isolation rather than one shared fuse approach
- Projects where a key-locked enclosure is useful for discouraging casual tampering
Who should think twice
- Anyone planning to power devices that draw more than 1A from a single output port
- Retrofits or clean wiring jobs where short included leads would force extra rewiring, stripping, or reuse of existing cabling
- Buyers who need a different voltage or a higher per-port current than this panel provides
Power budgeting: the part most people get wrong
Even though the box is labeled with a high total output figure, the practical limit is per port. Since each port is rated for up to 1A, you’ll want to confirm your camera (and any attached IR illuminator or accessories, if applicable) stays within that per-device draw. If your devices exceed the port limit, the protection may trigger and the affected channel may cycle rather than deliver stable power.
Cable and pigtail fit (a common practical concern)
The package includes 18 DC male pigtails. Some buyers report that for their specific installation style, the pigtails were too short and required additional handling, such as stripping more wire length or reusing longer leads from an older panel. If you are doing a neat pre-wire workflow, measure your required run length and connection method before assuming the included pigtails will be plug-and-play.
Verdict
Real HD’s 18-port 12V DC power distribution box is a solid fit for multi-camera CCTV and similar access-control-style projects when you can meet two constraints: your per-camera power draw fits within the 1A-per-port rating, and your wiring plan works with the included pigtail lengths. If you need a centralized, key-locked, per-channel protected power panel for up to 18 devices, it’s the type of unit that can simplify distribution, with the main tradeoff being installation flexibility.

FAQ
How many cameras can this power distribution box support?
It provides 18 separate 12V DC output channels, so it’s intended to support up to 18 cameras (assuming each camera stays within the per-port current limit).
What is the output limit per port?
Each output port is rated for up to 1A. Even if the total output capacity is higher, the per-port limit is what matters for individual devices.
Does it have individual protection for each channel?
Yes. Each port uses auto-reset PTC protection, which is designed to protect that channel if a current issue occurs, instead of relying on a single overall fuse.
Is this compatible with 12V DC CCTV cameras?
It’s designed for 12V DC security cameras and related low-voltage devices. It supports common camera formats in the CCTV ecosystem that operate on 12V DC, but you should still confirm the power draw and port wiring requirements for your specific models.
Are the included pigtails long enough for all installs?
Lead length needs vary by installation. Some buyers found the included pigtails short for their retrofit wiring needs, so it’s wise to plan your wiring path and measure before you rely on the included leads.
Does it include a key lock?
Yes. The unit uses a key-locked metal case, intended to help prevent unauthorized access to the power distribution panel.
