Custom & OEM →Who uses it, where it goes and how to install it
Written for the ZJIES1000D-P-4PT1T-DC (ordering code ZJIES1000D-P-4PT1T-DCH) from the manufacturer's datasheet: unmanaged, 4 × 10/100Base-T PoE (802.3af/at, up to 30 W each) + 1 × 10/100Base-T uplink, redundant 48 V DC (36–56 V) input, -40 to +75 °C (wide-temperature version), 32 mm wide IP40 DIN-rail housing.
Who it is for
- CCTV installers with small pole or cabinet sites — Four PoE ports power four IP cameras over their data cables from one 48 V supply in the cabinet, and one uplink port carries all four streams to the NVR or to a fibre converter. A 100 Mbps port is plenty for one camera.
- Traffic, parking and toll projects — Every PoE port supports PoE+ up to 30 W, so the four ports can feed heavier loads such as cameras with heaters or small PTZs at the same time (4 × 30 W = about 120 W). The wide-temperature version is rated -40 to +75 °C for unheated roadside boxes.
- Factories and machine builders — A 32 mm wide DIN-rail unit that powers IP phones, wireless APs or inspection cameras inside a control panel, with EN61000-4 Level 3 immunity to ESD, fast transients and surge for electrically noisy plants.
- Telecom and utility sites with 48 V DC — The 36–56 V input runs directly from a 48 V rectifier or battery plant, and the two inputs let you connect two separate supplies so the cameras keep running if one fails.
- Integrators and distributors — Nothing to configure, so it can be shipped pre-wired in a cabinet. The page offers neutral casing and OEM customisation; for 8 Gigabit PoE ports use the ZJIES1000D-P-8PGT-DCH instead.
Where and how to install
- DIN rail inside a closed cabinet — Clip it onto a 35 mm DIN rail (wall mounting is optional). The housing is IP40: it keeps out dust and fingers, not rain, so outdoors it must sit in a weatherproof enclosure. With four PoE+ loads the switch handles over 100 W, so leave free space above and below it and keep it away from heaters and transformers.
- Size the 48 V supply for the PoE load — The datasheet gives a maximum input current of 2.6 A at 48 V with all four ports at 30 W, about 125 W. Use a DIN-rail 48 V supply with some headroom (about 150 W or more) if you expect full PoE+ loads; four ordinary cameras need much less. Wire the second input to a second supply or battery for redundancy and fuse each feed.
- Ports: which is which — Ports 2–5 are the PoE ports for cameras, APs or phones; port 1 has no PoE and is the uplink to the NVR, a larger switch or a fibre media converter. PoE is delivered on pins 1, 2, 3, 6 (Endspan, Mode A), so use correctly terminated 4-pair cable to standard 802.3af/at devices.
- Copper runs, cable quality and surge — Every port is copper, so each run is limited to 100 m. For PoE+ loads near that distance use solid-copper Cat5e or Cat6, not copper-clad aluminium, which heats up and drops voltage. Cables that leave the cabinet to a camera on a pole or another building need an Ethernet surge protector, and the DIN rail and cabinet should be bonded to the site earth.
- Temperature and condensation — For outdoor or unconditioned cabinets order the wide-temperature version (-40 to +75 °C); the standard version is rated -10 to +60 °C. A sun-exposed metal box can run far hotter than the air, so shade it or vent it. Humidity is rated 5–95 % non-condensing: seal the cable glands and add a breather or anti-condensation heater at humid or coastal sites.
PoE budget / how many cameras
With only four PoE ports and up to 30 W on each, the port count, not the power budget, is what limits this switch: four ordinary cameras use a fraction of the 120 W, and even four PoE+ devices at full load fit. The 100 Mbps uplink also has room for four camera streams.

- Pick the ZJIES1000D-P-4PT1T-DC for up to four PoE devices in one cabinet within 100 m; pick the ZJIES1000D-P-8PGT-DCH for 8 PoE ports at Gigabit speed.
- If the uplink must go farther than 100 m, put a fibre media converter such as the ZJIC200-2 on port 1, or choose a PoE model with SFP ports such as the ZJIES1000D-P-8PGT2GB-DC.
- Pick a managed model such as the ZJIES3000D-P-8PGT-DCH if you need a self-healing ring, VLANs or remote monitoring.
Values from the manufacturer's ZJIES1000D-P-4PT1T datasheet; port numbering (port 1 uplink, ports 2–5 PoE) is from our page. Camera power draws and the 8 Mbps per camera bitrate are assumptions; 25.5 W is the IEEE 802.3at maximum at the powered device. ≈125 W = 2.6 A × 48 V.
4-Port PoE Switch FAQ — ZJIES1000D-P-4PT1T-DC
How many IP cameras can the ZJIES1000D-P-4PT1T-DC power?
It powers up to 4 devices on its 4 PoE ports (ports 2–5), each delivering up to 30 W under IEEE 802.3af/at, with a total budget of about 120 W — an average of 30 W per port even fully loaded. That covers 4 IP cameras, including PTZ-class units on any port.
What is the port layout and which ports carry PoE?
There are 5 x 10/100Base-T RJ45 ports in total: ports 2–5 supply PoE af/at, and 1 port serves as the data uplink to your NVR or router. PoE power rides pins 1, 2, 3 and 6 (V+/V+/V-/V-, Endspan MDI Alternative A) on the same cable as data.
What supply do I need to feed the switch?
A DC 48V source in the 36–56V range, wired to the 4-pin terminal with dual redundant input. Budget for a maximum input current of 2.6 A at 48V with PoE fully loaded. Reverse-polarity and overload protection cover wiring errors during installation.
Which devices besides cameras can it power?
Any IEEE 802.3af or 802.3at powered device: IP cameras, IP phones and wireless access points are the typical loads. Because each port negotiates up to 30 W (PoE+), higher-draw devices like outdoor APs run from the same switch as low-power cameras.
Can it operate in an outdoor CCTV cabinet?
Yes — standard temperature is -10 to +60°C and the wide-temperature version covers -40 to +75°C, with 5–95% non-condensing humidity. The fanless IP40 metal case (32 x 144 x 95 mm) mounts on DIN rail or wall, with EN61000-4 Level 3 EMS immunity, a 320,000-hour MTBF and 5-year warranty.
Do the cameras need their own power wiring?
No — data and power travel on a single Ethernet cable from each PoE port, so each camera position needs one cable run only. That removes local power supplies at every pole or wall point, cutting material and labour on small 4-camera CCTV installations.
Will the 100 Mbps ports of the ZJIES1000D-P-4PT1T-DC slow down 4K or 8 MP cameras?
Normally no. A typical IP camera stream is a few Mbps to around 16 Mbps even at 8 MP with H.265, far below 100 Mbps per port. The shared point is the single 100 Mbps uplink on port 1: four cameras at an assumed 8 Mbps each use about 32 Mbps, and even four at 16 Mbps (64 Mbps) fit. Where many cameras or high-bitrate streams must share one uplink, use a Gigabit model such as the ZJIES1000D-P-8PGT-DCH.
Can I power the ZJIES1000D-P-4PT1T-DC from a 12 V or 24 V solar battery?
Not directly. The input range is 36–56 V DC, so 12 V or 24 V is below it and the switch will not start. Use a 48 V battery bank, or a DC-DC converter with a regulated 48 V output sized for the PoE load (up to 2.6 A at 48 V). Remember that solar sizing must cover the switch plus every camera it powers, 24 hours a day.
Will the PoE ports damage a laptop or a device that is not PoE?
No, for standard devices. The ports follow IEEE 802.3af/at, and a standard PoE port only switches on power after it detects a valid PoE device signature, so a laptop or non-PoE camera just gets data. The opposite case matters more: older 'passive' 24 V PoE radios or cameras are not 802.3af/at devices and will not be powered by these ports.
Can I build a ring with several ZJIES1000D-P-4PT1T-DC switches?
No. It is unmanaged and no ring protocol, STP or RSTP is listed, so closing a loop between switches creates a broadcast storm that can stop the whole network. Connect these switches in a line or star only. For a self-healing ring along a road or fence, use managed models such as the ZJIES3000D-P-8PGT2GB-DCH with fibre ports.
The NVR is 400 m away. How do I connect the ZJIES1000D-P-4PT1T-DC?
Not with one copper cable: Ethernet over twisted pair is limited to 100 m, and this model has no fibre port. Put a fibre media converter (for example the ZJIC200-2) on the uplink port 1 in the same cabinet and a matching one at the NVR end, joined by fibre. If you prefer one box, choose a PoE switch with SFP uplinks such as the ZJIES1000D-P-8PGT2GB-DC.
What power connector does the ZJIES1000D-P-4PT1T-DC have, and do I need to confirm it before ordering?
Yes, please confirm the power connector with us before ordering. For Zhongxin Shutong products the power input type and connector can differ between versions and batches, so tell us your supply (AC or DC and the voltage), how you will wire it in the cabinet and your country's plug standard, and we confirm the exact connector and supply version of the ZJIES1000D-P-4PT1T-DC for your order.
