TIENFOKOTA PoE Splitter 48V to 12V IP55 Waterproof (2-Pack) for IP Cameras
Reviews
Product description
What it is
The TIENFOKOTA PoE Splitter is a compact power accessory designed to derive 12V DC from a 48V PoE source. Sold as a 2-pack, it targets outdoor or exposed installations where cameras or other 12V devices need clean power from an existing PoE network without extra adapters.
How it helps your setup
On paper, it delivers up to 12W (1A) at 12V from a 48V input while maintaining standard Ethernet data transmission (up to 100 Mbps) in line with IEEE 802.3af/at. The IP55-rated housing signals suitability for rain, dust and moisture exposure, which is useful for external camera sites, industrial enclosures or any installation where weather protection is a priority.
What stands out in use
The unit is designed for plug‑and‑play deployment. A standard RJ45 interface keeps connections straightforward, and there’s no need for extra tools or complex wiring — just connect the PoE input and your 12V device, and power should be available. The device claims active conversion to guard against voltage fluctuations, which can help sensitive cameras or peripheral devices maintain stable operation across typical PoE installations.
What may not convince you
If you’re deploying high‑definition, high‑demand video or sensors, the 12W output could be a ceiling depending on your device’s load, and you might need to review actual power draw in practice. Also, the maximums stated are under test conditions, real‑world performance can vary with cable length, temperature and network traffic. The IP55 rating is robust, but it is not a guarantee of long‑term reliability in extreme environments without proper mounting and weather sealing.
Who it’s for
This splitter suits DIY installers and small to mid‑scale outdoor surveillance or remote network setups where a single PoE line must both carry data and power a 12V device. It’s practical if you want to reduce cabling clutter and avoid multiple wall adapters for each camera or 12V device in a budget‑conscious way.
Who it isn’t for
If your 12V device draws more than 1A consistently, or if you require higher power budgets for several devices, this splitter may not be the best option. It’s also not ideal where the environment is harsher than IP55 allows or where 802.3af/at compatibility is not present in the power source.
Practical considerations before buying
- Confirm your PoE injector or switch supports 802.3af/at to ensure compatibility.
- Check the actual 12V load of the device to confirm it stays within the 1A/12W limit.
- Plan for mounting so the IP55 seal remains effective, outdoor installations benefit from proper enclosure and drainage.
- Consider cable length, as longer runs can affect voltage delivery and performance.
Comparisons and buying logic
If you’re weighing options for outdoor PoE power, this splitter provides a simple, non‑overengineered approach to power a 12V device from a PoE line, without investing in specialised inline DC converters or weatherproof power bricks. For projects where more headroom is required or where you need multi‑port power distribution, alternatives that offer higher wattage or more robust enclosures may be worth exploring.
Is it worth it?
Is it worth it?
It makes sense if you need a straightforward, weather‑resistant way to power a 12V device from a PoE source and your load stays within the 1A/12W window. If your setup demands more power or a proven higher‑duty enclosure, you may want to look at alternatives with greater headroom.
FAQ
- What data speed does it support? It supports up to 100 Mbps data transmission as part of the PoE standard compatibility.
- How weatherproof is it? It is IP55 rated, suitable for rain and dust in outdoor or exposed environments.
- Can I power multiple devices with this? The unit is designed for powering a single 12V device per splitter, using two in parallel is possible but would depend on the PoE source and overall load.
