Can I use this extender with a 24V passive POE switch?

No, you cannot use this extender with a 15V-24V non-standard passive POE switch. This device is strictly designed to operate with standard 48V POE switches (IEEE 802.3af/at). Using a lower voltage switch will result in the cameras failing to power on.

Can I connect the POE output ports directly to my NVR or router?

Absolutely not. You must never connect the POE output ports to an NVR, a standard Gigabit switch, or a router. The output ports carry 48V of power; plugging them into a non-POE receiving port will instantly cause permanent electrical damage to that device.

Does this 1-to-2 POE splitter require an external power adapter?

No, this POE splitter does not require any external power adapters. It draws its operating power (less than 1W) directly from the incoming POE Ethernet cable, making it incredibly easy to install in ceiling spaces or outdoor junction boxes.

What is the maximum distance I can run the Ethernet cables?

You can run a standard Cat5e or Cat6 Ethernet cable up to 100 meters from your main POE switch to the extender's input port. From the extender's output ports, you can run another 100 meters of cable to your IP cameras, effectively doubling your network reach.

Can I get advice on calculating my POE power budget at your store?

Yes, you can bring your IP camera specifications to Sun Cheong Computer Co. Ltd. (新昌電腦有限公司) in Sham Shui Po. Our technical staff will help you calculate the total wattage required and ensure your main POE switch has enough power to drive two cameras through this extender.

Short Product Description

The 1-to-2 POE Extender Switch (JHJ-7703W) is a commercial-grade network splitter designed to power two IP security cameras using only a single Ethernet cable. Operating on standard 48V IEEE 802.3af/at protocols, this unmanaged repeater takes one POE input and splits it into two 100Mbps POE outputs, drastically reducing wiring costs and installation time for CCTV systems. Available for instant pickup at Sun Cheong Computer Co. Ltd.(新昌電腦有限公司) in Sham Shui Po, our technical staff can help you verify your main POE switch's power budget to ensure safe and stable camera operation.

Key Features

1-to-2 Expansion: Splits a single POE network cable into two POE outputs, allowing two IP cameras to share one main cable run.
Extended Range: Supports up to 100 meters of input transmission and an additional 100 meters of output transmission.
Standard 48V Support: Fully compatible with IEEE 802.3af (15.4W) and 802.3at (30W) standard POE switches.
Ultra-Low Power Consumption: The internal circuitry draws less than 1W, generating virtually no heat and preventing component aging.
Built-in Surge Protection: Comes standard with lightning and surge protection to secure your outdoor CCTV installations.
Gold-Plated RJ45 Ports: Ensures anti-oxidation and maintains smooth, uninterrupted data transmission over long periods.

Full Product Description

Cost-Effective CCTV Wiring Expansion

This 1-to-2 POE Extender provides a highly efficient solution for expanding your IP camera network without running additional cables back to the main server room. By installing this compact device at the end of a single 100-meter Ethernet run, you can instantly branch out to power two separate POE cameras for another 100 meters. This daisy-chain capability significantly reduces labor costs, cable clutter, and the need for expensive multi-port switches in small surveillance zones.

Strict Standard 48V POE Compatibility

The JHJ-7703W POE Splitter is engineered to work exclusively with standard 48V POE switches that comply with IEEE 802.3af or 802.3at protocols. It features a highly efficient internal circuit that consumes less than 1W of power, ensuring that almost all the incoming electricity is passed directly to your cameras. The device is also equipped with built-in surge and lightning protection, safeguarding your expensive surveillance equipment from unexpected power spikes during outdoor storms.

Pro Tip from Our Technicians

When deploying this POE Network Extender, our Sham Shui Po technical team strictly warns against using non-standard 15V-24V POE switches, as they will not power this device and may cause system failure. Furthermore, you must never connect the "POE Output" ports directly to a Gigabit switch or an NVR (Network Video Recorder) port. The output ports carry 48V power (Pins 45+, 78-); plugging them into non-POE receiving equipment will instantly destroy the network card of the connected device.
