18-Channel DC 12-Volt 20-Amp Output CCTV Distributed Power Supply Box/Converter with AC Plug and Lock(20A 18-Channel)
Quick take
This 18-channel CCTV distributed power supply converts AC power into a 12V DC output and is built for systems that need power distribution across many camera runs. It includes individualized protection elements per output (PTC fuse and LED indicator), plus broader surge and over-current protection features. The main buying caveat is to verify total camera power needs and plan mounting, since the physical layout for the cable pigtails may not match every setup.
Pros and cons
Pros
- 18-channel 12V DC distribution designed for multi-camera CCTV installs.
- Per-output safety monitoring, with an independent PTC fuse and an LED indicator for each channel.
- Multiple layers of protection features, including overload/short-circuit protection and surge/high-voltage protection.
- Works as a practical replacement and backup power unit for existing CCTV systems.
Cons
- Setup may require extra mounting effort, since cable pass-through options may not fit every enclosure layout.
- You still need to calculate your camera draw to stay within the unit’s total output capacity.
What buyers think
Buyer-review evidence is limited but generally points to reliable operation after installation. A practical mounting concern came up: the cable pigtail routing may require drilling additional holes depending on where you place the box and how your wiring path lines up. Overall, the feedback themes focus more on “it works” and “power and safety feel secure” than on advanced configuration or software behavior.
How this CCTV power supply is meant to be used
This model is built to distribute power to many cameras from a single 12V DC source. It is designed for 18 camera channels and is intended for multi-run surveillance builds where centralized power simplifies wiring compared with powering each camera separately.
Protection features that matter for multi-camera setups
When you run a lot of cameras, power protection becomes part of reliability, not just safety. This unit emphasizes channel-level isolation and indication:
- Independent PTC fuse and LED per output: If there is an issue on a particular channel, only that affected output should be impacted, helping other channels stay running.
- Short-circuit protection: A short condition is handled by the independent PTC fuse opening the circuit and then resuming normal operation once the issue is resolved.
- Over-current and overload protections: It includes automatic over-current protection that transitions to a self-protection state when current flow is excessive.
- High-voltage and lightning protection: It includes surge and high-voltage protection to help protect connected equipment from spikes.
If you are wiring cameras across long runs or in environments where electrical events can happen, these layered protections are the key differentiators to look for in distributed CCTV power supplies.
Power capacity, DVR compatibility, and the “do I have enough watts?” question
The unit’s total output wattage is listed as 240W (with an overall 20A output capability). The practical takeaway is that you should add up your cameras’ power requirements and confirm your system stays within the power budget.
Installation and mounting considerations
This is a metal-enclosure distributed power box intended for permanent installs. One review mention suggests that depending on your mounting location, you may need to drill additional holes to route the cable pigtails cleanly. Before purchase, think about:
- Where the AC plug enters and how you’ll route it safely to the box.
- How your camera cable pass-through points line up with the knockout hole layout.
- Whether you need straight-line routing or a more concealed “behind the mount” wiring path.
If you plan careful cable management, this box can still work well, but be ready for the possibility of minor enclosure modifications.
Pros and cons recap
Best for
- Anyone building or expanding an 18-camera CCTV system that needs centralized 12V DC power distribution.
- Buyers who prioritize per-channel protection (independent PTC fuse and LED indication) to reduce the blast radius of a single camera power fault.
- Home or small business installers replacing a failing or insufficient distributed power unit.
Who should avoid it
- Buyers who do not want to do basic installation work (drilling or re-routing) may find the physical knockouts and cable routing less convenient.
- If your camera count or total power draw does not align with the 12V 20A and 240W capacity, you may be better served by a supply that more closely matches your actual load needs.
Is it worth it?
This is a straightforward option if you need a centralized 18-channel 12V DC power distribution box with multi-layer protections and channel-level protection behavior. Based on the available buyer feedback themes, it tends to function reliably after setup and serves well as a replacement or backup power supply. The main reason it might not be the right fit is if your wiring and mounting layout does not match the enclosure pass-throughs, or if your camera wattage calculations are not done up front.
FAQ
How many cameras can this power supply run?
It is designed for an 18-channel CCTV setup, distributing 12V DC power across up to 18 outputs.
What is the output wattage and current rating?
The listed total output wattage is 240W, with an overall 12V DC output capability rated at 20A.
Does it protect each camera channel individually?
Yes. Each output includes its own PTC fuse and LED indicator, which is intended to isolate faults so other channels can keep running.
Will it automatically recover after a short circuit or overload?
It includes short-circuit protection using the independent PTC fuse, and the protection behavior is described as opening the circuit and then resuming normal operation once the issue is resolved.
Do I need to do any drilling to mount it?
It may depend on where you mount the box and how your cable pigtails align.
What should I check before buying?
Confirm your cameras’ total power draw against the unit’s 12V 20A, 240W capacity, and plan routing so the mounting and pass-through points work for your setup.
