    There is a product by Motorola called the Powerline MU. It is designed to provide MTU/MDU's (apartments) with high-speed broadband.

     

     

    Basically, the 'access point' is installed at the meter bank. This lights the entire complex up on that meter bank. All of the electrical outlets on the meter bank there now have high-speed connectivity. Plug in your modem and you are set.

     

     

    There are some catches on a system design such as quality/condition of the electrical systems interconnects (dirty breaker contacts, poor electrical wiring, bridge taps, etc) that can wreak havoc with such a system.

     

     

    If you want to know more check out Motorola's website.

    I'd say this all depends on what the path looks like. How much "stuff" in the middle greatly affects what you are dealing with.

     

    I'd stay away from 900MHz systems as those can have issues with spurious noise associated with high-voltage transmission lines and substations.

     

     

     

    But, you never know. I have a WISP customer that is maybe 3 blocks from a big substation, and they are on our 900MHz system. The antenna is pointed right over the top of the substation and there is no problems what so ever.

     

     

    If you can PM me with a google earth image I can take a look at it and maybe give you some thoughts.

    Good day, new member here. I came across this forum while researching some information on Toshiba cameras. After searching and browsing the forums I figured this is a great place and I should register.

     

    I currently work as a network engineer for a wireless ISP so I have a fair amount of experience dealing with wireless technologies and IP network design. Recently though, my company I work for has decided to branch out and push into CCTV systems. I will admit I am a bit aprehensive about this whole deal as I really have no business doing CCTV but I guess I can figure anything out so I'm supposed to do this too...

     

     

    My background is pretty much zero when it comes to CCTV. The largest CCTV job I have done is a multi-site (3 cameras/site) system using Axis IP cameras and linking them back to an ONSSI DVR. The neat part is this system runs over a pair of T-1's per site and the T's are transported via high-capacity microwave.

     

     

    Anyhow, I look forward to contributing here.
