I have had 2 sets of switches die to lightning strikes near the house before finding these. Took me a while to figure out what was happening. I have 4 ethernet runs over 100ft. Now with a full set of the WatchfulEyes (8, 2 on each end of each run) I haven't had any issues through the last 3 major lightning storms.
Testing with speedtest.net, the WatchfulEye doesn't seem to have any effect on speed, reliability, jitter, or ping. I thought I would at least notice some speed testing issues after install, but I didnt see any issues, at least for my length of runs.
If I make more runs I will buy more.

Ethernet & PoE Surge Protector
Technical Data:
- WTH-SG/RJ45 Series surge protective devices are applied to surge protection for data communication systems.
- WTH-SG/RJ45-E is connected in series in CAT6 network cables, compatible with 10/100/1000/10000 (10G) Base-T Ethernet systems, protecting the equipment which are connected to the network (e.g. computers, routers, PoE devices, etc.) against damages by over-voltage surge.
- Max. Discharge Current: 20kA (line to GND/PE)
- Max Watt: 90W (PoE)
- Data Rate: 100/1000Mbps
- Bandwidth (3db) per pair: >250MHz
- Insertion Loss: <0.5dB @100MHz
- Pairs Protected: 1-2,3-6,4-5,7-8
- Protective Element: GDT, TVS
- DIN Rail EN60715: 35mm top-hat rail

Application for Ethernet
- What are the advantages of the GDT+TVS type surge protection? It provides a two-step surge protection mode: the first-stage GDT protection, releasing strong surge intrusion and reduce the strength of the surge; it is followed up the second-stage TVS fine protection, achieving a lower residual voltage value.
- If the wires on the line side and the equipment side are connected reversely, will it affect surge protection? When the wire is connected reversely, TVS becomes pre-stage protection, and GDT is post-stage protection. The nominal discharge current of TVS protection will be much lower than GDT. If it encounters a surge intrusion, it may cause damage to the TVS. The second-stage GDT protection will also play a role in surge protection, but the residual voltage value will increase, which is a risk to the protected equipment.
Application for PoE
- There’s no TVS protection on 4-5 and 7-8 lines of WTH-SG/RJ45-E, does it affect the system? 4-5 and 7-8 line TVS protection is applied for 1000M network. If your system is a 100M network PoE system, 4-5 and 7-8 are PoE power lines, which already has GDT protection, and it is not necessary for TVS surge protection.
