    CCTV HDMI to LAN

    let me help dispel something here, cat 5e, solid, 24 gauge cable installed without knicking the jackets of the conductors themselves is sufficient to operate ANYTHING currently made. Category 6 cable's improvements over 5e are strictly related to near end and far end crosstalk for Ethernet transmissions at over 350 mhz. Your cat 5e cable is completely capable of running gb Ethernet at distance as well as hdmi over UTP to standard distances of decent equipment of 100 ish meters and any camera IP/or analog with baluns to the max distance of 100m for IP and whatever the balun is rated. Changing from 5e to 6 for anything other than the most advanced Ethernet networks with the most advanced Ethernet devices will gain you a net of NOTHING! And no your brand new computer does not count as an advanced ethernet device. For 99% of these types of issues look to a few very simple things, primarily bad techniques of installation, crimped, cut, knicked wires, end connectors installed where the wire twist isn't maintained , ie 6 inches of conductors not inside the jacket and the end crimped on, solid copper crimp ends used on stranded wire, or the opposite, miswired ends, or if terminating on jacks, miswired jacks and or bad patch cords. I've also become recently aware that hdmi over UTP manufacturers apparently aren't that familiar with standard installation procedures and their products do not play well when they are connected via any method other than a straight through cable with rj 45's on each end, no jacks, patch cords, anything, just a cable sticking out of the wall with an end on it. Looks terrible and that's why we don't do that but hey what do we know. Its become trendy to say I want cat6 or to give cat6 requirements for a device but the truth is the equipment that will actually utilize the advantages of cat6 vs 5e isn't even on the market yet. If you don't believe all of the above, category 7 standards have been adopted, try and find it or even better get a quote to install it.
  2. can you clarify? You want to be able to see cameras on multiple computers? Put the dvr on network and use the client to view over network from any pc on that network.
  3. look on craigslist for an alarm tech (actually employed by an alarm company) looking for extra work. Those guys are always running wires in existing residential construction and will get it done clean fast and cheap. You're hesitant to start drilling into your house and you should be as you don't know all the ins and outs of adding electronics wiring to the home. You should be! There are hundreds of ways to screw up and only experience lets you avoid them. No matter how many pictures are posted NOONE can guide you through everything that needs to be considered unless they are there and do it, and even then we can still screw up some. Experience lets us have the best chance at success or at least a fixable screw up. Hire a local guy who knows what hes doing.
