how to watch surveillance or cctv camera from different location?

   Well, you are really talking about a wireless (aka radio) linked setup or setting up the cameras in an ipcam format.

   The traditional way, but problematic over much more than a mile or two, would be to add a radio transmitter to each camera and have a single receiver per camera at your reception/viewing point. There are also multi-receiver units that you can use instead of one receiver per channel.

   The receiver’s output plugs into one of the video/camera inputs intended for wired cameras, at the monitor/recorder/multiplexer. If it’s a multi-receiver, it has multiple outputs that you send one to each available input on the multiplexer.

   The multiplexer is the bit that takes the multiple inputs, and provides an output that can deliver the switched input from any one camera, any grouped ordered combination, or cycle between all inputs in sequence or randomly – on cheaper systems, the multiplexer is integral to the monitor, on more expensive stuff, it’s standalone and you connect all to the standalone muliplexer.

   But given a lot of complications over range and possibily licensing… depending on where you are, and also prices…

   Route 2 is probably more practical, the ipcam approach. If you already have an existing setup, it could be expensive, but going down the ipcam route would also allow upgrading to a digital recording system.

   An IPCAM type CCTV system uses wired or wireless digital video camera (at the cheapest end of the scale, nothing more than a cheap webcam with micro server built in and a wireless/ethernet card) or the microserver/wireless/ethernet add on that takes video from an existing wireless camera – these ‘ipcams’ then stream their output over the internet, or over an ethernet or localised wifi network, and can be viewed directly using a viewing software on a networked enabled PC/MAC etc.

   The ‘ipcams’ are, in a more serious context, usually streamed back to a server where the streams can be captured and archived for reference.

   And inbetween these extremes, there are all-in-one wireless camera/multiplexer/recorder kits (Swann being a notably available make) – that have 4 wireless cameras that talk to a combined mutiplexer/digital recorder, and you can view the content or live feeds via the mutiplexer locallly or in ‘ipcam’ fashion over the internet/ethernet/wifi network on some versions.

   Hope it helps, and apologies for not including examples of actual products, because it highly depends on where you are for availability and how far you are prepared to venture to look for examples.

   you will need an IP camera , or Network fixed cable enabled camera plugged into a router , and plugged into a DSL phone line , or a WIRELESS wi-fi enabled IP Camera linked to a laptop with gprs access to a mobile broadband service

   software used on your computer through the router will connect or a static IP from a fixed service will allow you to connect to your camera direct through access at remote third party locations , providing you have the required login you have assigned to the camera’s software

   if you only have analog connections to a recording system , then I would suggest an upgrade

   Your surveillance systems at your three businesses would have to be connected to a computer at each business. And each of those computers would have to have internet access. If that’s the case, then you could connect remotely to each of those computers and see what is going on. Check with the manufacturers of your surveillance system(s); they will be able to help you connect all three.

   Good luck!
