Discussing Ethernet cables involves understanding their types, speeds, and applications.
Hello, I just set up a video protection system 150 meters away from my house. It includes a control unit and three cameras connected via RJ45 cables. Since I'm in a remote area with no fiber or stable connection, I've installed a mobile antenna and often switch to hotspot mode for internet access on my PC. To reach the control unit remotely, I use a 4G SIM router, which I plan to move later for safety. For added security, I want to hide the control unit if needed. I'm considering adding two to three cameras around the garden and entrance. One idea is using a cable that can accommodate more than three Ethernet connections. I found this option here: https://linkitaly.com/products/multicore...et-cables/. Do you have any suggestions or alternatives? Best regards.
RJ45/cat 6 doesn't function beyond 100 meters. Switching to fiber is the top choice, with costs similar to what you'd expect.
With two components and a fiber connecting them, would it function as intended? The process of matching the input to the output signal is unclear. Please clarify the setup.
Similar to previous points, the upper limit for a single Ethernet connection is 100 meters. One choice would be to install fiber, but you'd also need power for the fiber-to-Ethernet adapter, which isn't ideal. You might consider using a network switch to combine data from all cameras over one Ethernet link. Another approach involves using a high-quality Ethernet cable up to 100 meters and pairing it with a PoE-enabled switch that can be powered via Power Over Ethernet (PoE). If your cameras are equipped to draw power directly from the Ethernet port, you eliminate the need for separate power sources. MicroTik and Ubiquity offer switches compatible with PoE, such as the RB750UPr2 and RB750P-PBr2 models, which include PoE inputs and can support multiple ports. For instance, the outdoor version of the RB750UPr2 can be mounted on a pole and features Ethernet input with PoE capability, along with four Ethernet ports powered through PoE. You could also find a PoE injector that fits in your home to supply power directly to the Ethernet cable, enabling the switch to operate and power connected devices. If cameras are designed to draw power from the Ethernet connection, you won't require additional wiring. MicroTik and Ubiquity provide suitable switches for PoE applications, as detailed on their product pages. For longer runs beyond 100 meters, coaxial cables or VDSL (twisted pair) can be used, though they necessitate media converters at both ends. VDSL supports affordable cables up to 1000 meters and delivers speeds suitable for a few cameras. An example converter is available on Amazon. If you opt for PoE powering your cameras, you must assess each camera's power needs and select an appropriate injector to deliver sufficient wattage. Another alternative involves using coaxial cables or fiber optics, which allow distances exceeding 100 meters. In such cases, media converters are essential at both ends. With VDSL, you can achieve reasonable speeds for multiple cameras, but bandwidth limitations may apply if you rely on lower data rates. If bandwidth isn't critical, running two Ethernet cables simultaneously can work—each carrying separate streams of data and power, with PoE injectors handling the power supply.
For a direct wired link as discussed earlier, the sole choice is a fiber optic cable. Multi-Mode LC UPC OM3 cables could work, though signal quality over that length may require verification. After that, you can deploy a media converter at the location to transform the optical signals back into electrical form for your security system or nearby router.
I’ll opt for a straightforward media converter instead of a switch.
Check out the TP-Link model on Amazon; it should fit the setup.
Once that’s in place, I’ll order a 1000-baseLX and OS2 cable—single mode is ideal here, no need for multimode.
