It is certainly possible to convert HDMI to another type of signal. However, Coax is not a signal. coax is a type of cable that will carry several different types of signal, all of varying qualities. The highest quality signal over "coax" is HD-SDI or SD-SDI. This is a broadcast level digital signal, and can be either HD or SD Only the most expensive monitors or display devices have an HD-SDI input. The input is BNC 99.9% of the time. Another type of more "coax" signal is composite video. This signal is the yellow connector and is usually an RCA type connector. Composite video is always standard definition. Lastly, there is RF. This signal used to be the lowest quality, and was the standard in TV transmission until the digital changeover in 2009. This is the Screw type F connector. Before that time, it was always standard definition. Since the transition, it can be HD, but must be Digital RF. In order for an older TV to read Digital RF, it must have a QAM tuner either internally, or externally. Now comes the HDMI part. It can be very frustrating to try to convert HDMI to anything because of HDCP compliancy. HDCP is (very simply defined) Hollywood's way of controlling how their content is displayed. Every device in an HDMI chain must meet HDCP compliancy. If even one device is not, the content will not display. There are several other HDCP issues, which can be found on Extron.com. Most devices that convert HDMI to something else will not allow movie content in HD to pass. If you happen to have "ripped" movies, the easiest (though far from cheap) way to convert is with some sort of HD modulator (ZeeVee makes one as well as Contemporary Research). By using this type of device, you are essentially creating your own closed circuit TV system. Though this may sound cool, it is pretty expensive, and probably not the answer you are looking for.
Ok, once again a variety of answers below, each either right in part but only for the part the writer is thinking about, or dead wrong.As the questioner does not specify if this is the WAN cable to the Modem or CPE router LAN connection, nor does the question specify twisted pairs for DSL, COAX for Cable modems, or Fiber Optic Cables, there are four different answers.DSL (Not all DSL is ADSL). Yes it matters but you have no control over it. The Telco or ISP that owns the copper and the DSLAM unit (be it at the CO or a remote unit) which your DSL device connects with are typically owned by the provider. The distance is in relation partially to the gauge of the wire in the pairs. It is also affected by other wires in the path that may provide interference or crosstalk. If your provider is telling you distance is the problem, the provider may be telling the truth. However the provider may be covering for bad wire. If you hear a frying noise on your landline phone, that means you have a problem that the provider needs to fix before he can legitimately tell you it is distance.Cable Modems. Here once again distance is a factor and the cable provider’s head-end server can’t be too far away. However, if your TV picture is clear on an HD channel, distance should not be a factor. If you can’t get a clear picture, push your provider to fix that! :-)Fiber. Yes it can be but… there are two factors related to distance. Typically you are served by what is called a ftth connection (Fiber to the Home). This is a single fiber core that will connect to a NAP (Network Access Point) which splits the light source from the provider’s fiber switch between many users. The distance between the switch and the NAP safely can be 20 miles (32 km) but the distance from the NAP to your modem may be limited to 1.5 miles (2.4 km). This depends somewhat on how far away your NAP is from the Switch. As NAPs divide the light between the users, the distance each user can be is a diminished by the number of members connected to the NAP.Ethernet inside your home. I don’t know why someone said 3 meters. It’s sort of funny. The guy who gave you the exact feet equivalent of 100 meters was right, though we typically round it back to 300 feet. So long has you have a proper cable, you don’t need to go shorter. If you need to go longer, put a Ethernet switch in the middle.
How to Wire Cat 5/Cat 6 Security CamerasThere are some important details needed to attend to on running cables and wires for security cameras. If you are thinking about running the Cat 5/Cat 6 over 300 feet in length, it’s a good idea to check their specifications for transmitting distance as well as IP camera cable distance.The longer the cable goes, the more signal will be compromised accordingly. You can use a switch to act as a signal repeater in the middle of the line or you can make your long run with fiber optic cable.Besides, if you are running Cat 5/Cat 6 cables outside the house, keep in mind that you need to bury/protect them properly by using PVC conduit or metal conduit in line with your actual needs.How to Wire CCTV Cameras over Cat 5 CablesIn sharp contrast to IP security camera over Cat 5/Cat 6, analog CCTV cameras/systems are powered by separate cables (coaxial BNC cable & DC power cable) for electricity and video signal transmission, which increases troubles of running different cables around the house.Because of advanced PoE Ethernet technology, more traditional CCTV security cameras can be powered by Ethernet Cat5/ Cat 6 cables to run long-distance cables and reduce wiring hassles.Benefits of wiring CCTV cameras over Cat 5/6 EthernetSingle Ethernet cable to minimize wiring hassles Extend video transmission distanceExtend video transmission distanceEasy to integrate with existing Cat5 Ethernet infrastructureFuture –proofTo wire CCTV cameras over Cat5 Ethernet cable, CCTV video baluns, an electrical device converting balanced/unbalanced signal, are needed to transmit CCTV video signal over Cat 5, known as Unshielded Twisted-Pair(UTP) as well, for example, this passive video balun with the power connector and RJ45 Cat 5 data transmitter.There are some videos detailing how to wire and install CCTV cameras over Ethernet Cat 5/6 cables. For example, one video explains how to connect Cat 5 cable to CCTV security camera using a balun. Another video shows using Cat 5 cable and baluns to connect a CCTV camera to the DVR.
Do hdmi cables really make a difference on an HDTV?
You don't say what you would be comparing to, so the answer is ... maybe. Here's my take. The main reason for HDMI are not better picture. At most the difference will be minor vs Component, although there are much bigger differences vs S-video or Composite. If you are using a 1080p HDTV with a Blu-ray or upconverting DVD player as a source HDMI is the preferred connection -- end of story. It's the only way to get 1080p. The only other viable choice is Component (See the first Link) ... but it is normally limited by hardware to 1080i. Also HDMI facilitates the highest quality audio formats (digital coax or optical are limited, and discrete multichannel audio is not allways an option since many Blu-ray players don't support it). On a 720p HDTV (and that includes those sold as 1080i) Component is still a good option. In most cases the theoretical performance advantage of HDMI (as a digital rather than analog connection) are exactly that, theoretical. A future consideration is HDCP (See 2nd link). When fully implemented HD video will ONLY be available via HDMI because analog connections will be downsampled to sub-HD resolution. And HDMI will cut off video entirely if both ends of the connection are not HDCP compliant. For this reason all components intended for HD video should always be verified to be HDCP compliant. Don't buy anything that isn't. Another consideration outside the scope of your question (effect on performance) is that HDMI is a single cable solution since it can carry both HD video and multichannel audio. Put simply it simplifies connections and can can be less expensive that the multiple cables required otherwise. Finally, you don't (normally) require expensive HDMI cables (See 3rd link). They basically work or they don't, so $10-$15 is all you need to spend (unless you want to make long (>15') runs or embed the cables in the wall (in which case a suitable rated cable is required). The 4th link is a good on-line source for basic HDMI cables (always buy HDMI version 1.3 or better -- they are more "future proof").
What is the maximum length of an RG6 cable?
The highest video resolution currently possible is HDMI, but one of the drawbacks of this technology is that the HDMI cable is not suggested for long cable runs, due to the fact that HDMI cable is manufactured out of twisted pairs of copper conductors that are small-gauge, instead of the usual coaxial cable, and this can cause problems when the HDMI cable needs to be run over 50 feet in length. With twisted pairs cable, impedance can not be kept under strict control. Without this strict control, the signal may be reflected along the length of the cable between the source and the sink of the signal. This can cause interference with the source bit-stream. The usual specification length of maximum run for HDMI cable is normally about 50 feet, or approximately 15 yards. The maximum cable run that will be efficient will be different for each individual cable, depending on the quality specifications of the cable manufacturer. A higher quality cable will cost more, but will also run further before any additional devices and technology are needed. Generally, the thicker the copper wire is in the pairs, the more costly the cable is, but the longer that cable can be run before experiencing signal problems. To have HDMI cable that runs over the maximum effective length, 50 feet to 60 feet, will require additional technologies and devices. There are several excellent ways to extend your HDMI cable run and keep the signal effectiveness. When an HDMI cable length gets too long the signal loses strength. This results in picture distortion, sparklies (where single pixels drop out of the picture), or no picture display at all, only sound capabilities. If any of these problems occur than the cable length is too long, and the signal needs to be adjusted by additional devices. The available options to extend the HDMI cable run and still have a usable signal are various. There are signal restorers, signal boosters, signal extenders, signal equalizers, cables with thicker conductors,and fiber optic cables. The cost and effectiveness of these methods vary according to the method used.
I want the best cable of cctv camera for long distance, up to 150 meter?
RG59 normally with the 18 g 2 conductor for power cable is normally the best cable to use when your at distances under 1000 feet or 300 meters. (only use the RG59 with 95% copper ) There is an RG6 for camera use that is also 95% copper, don't confuse this with RG6 for cable TV since it is aluminum. This specialized copper RG6 will work for cameras over 700 feet (also under lol) You can also transfer the video over CAT5 or CAT6 phone cable using Balun connectors and you can get non-powered or powered balun connectors and run the camera that way for over a mile. You would normally power your camera at the location and run the video over the CAT5 back to your recorder etc....The non powered balun connectors are about $25 each. Do a search to find baluns and compare prices.
The maximum length depends on a couple of things such as the transmission speed and the Category of twisted-pair LAN cable being used.Typically, for 10/100/1000 mbps links, 100 meters (approx. 300 ft.) is the maximum length for cables with Cat5e or better. A 10 gbps link requires Cat6 cabling for up to 55 meters or Cat6a for up to 100 meters.To extend copper ethernet connections farther than 100 meters, an intermediary network switch can be added or cascaded in between spans, which will effectively extend the connection another 100 meters.For cascading ethernet in general, it is recommended to follow the “5–4–3 Rule”. There should only be a maximum of FIVE segments connected to FOUR repeaters/switches, and only THREE of the segments can have users on them.Alternatively, for longer single-segment spans above 100 meters up to well into the hundreds or thousands of kilometers, fiber optics are used.
How many feet of coaxial cable can you run without signal loss?
Signal loss occurs along every foot of coaxial cable. The amount of loss is dependent upon the frequency of the signal, the length of the coaxial cable run and the quality of the cable used. For a typical digital TV signal in the UHF range with RG-6 coaxial cable, you can figure 1.4 - 2.0 dB loss per 100 foot. This results in a 7.0 - 10.0 dB cable signal loss in your application. Also, remember that each connector results in an additional 3 dB loss. So you can easily lose 13.0 - 16.0 dB in your total application. The best way to deal with this loss is to use a distribution amplifier at the start of your 500 foot coaxial run. Select a distribution amp with at least a 16 - 20.0 dB gain to compensate for these coaxial losses and you should be find.
I want to extend my ethernet to over 300 feet. How do I do this?
From your question, I'm not 100% sure what to tell you. From the main question, you say you want to extend over 300 feet, but in the description, you say you want to extend TO 300 feet. The reason that makes a big difference (and forgive me if you are already aware of this) is because the specifications for running a Cat5 Ethernet cable limit you to 328 feet (100 meters). If you are running to 300 feet (or slightly over, as long as you are under 328 feet), then you are OK... all you need to do is run a Cat5 cable that distance. However, if you are breaking the 328 foot barrier, you will need some kind of powered repeater in order to run from your source to the IP cameras. However, the 10BaseT Ethernet specs make extending the length simple... all you need as a repeater is a powered HUB or switch. The cheapest one you can find will do. The most basic hardware setup you will need would be whatever equipment you have in your office where the server, switches and camera system are located. Up to 328 feet of Cat5 or Cat6 cabling and your cameras. And, if you are going to surpass the 328 foot barrier, you'll need a HUB or switch somewhere in the middle of each cable run from camera server to the IP cameras themselves. If you have to break the 328 foot barrier and it's not possible to put a repeater somewhere in the middle of your cable run (between the camera server and the cameras themselves), then your best option might be fiber optic cabling. In this case you would need a pair of fiber optic transceivers, one in the room where the camera server is (to convert from Cat5 to fiber) and one where the cameras are (to covert from fiber back to Cat5). You would then run a single fiber cable the bulk of the distance. If you need to go this way, add this to your post and I will help with finding the proper transceivers you'll need for the job. Hope that made sense!
