4 external cameras will need to have infrared (IR) capability so as to see at night. You will require a 4 channel Digital video recorder (DVR) to record the images from your 4cameras. Each camera will require a CAT 5 and coaxial cable. Cat 5 for power & coaxial for picture back to DVR. Cat 5 can be used for pictures too but for analogue cameras coaxial is best. You will require a monitor at the DVR. To be able to access the system from your PC or Smartphone you need to connect your broadband to your DVR. You will need to ask your broadband supplier for what's called a static IP address. This is required so as you can upload the images from your cameras via your DVR to your phone or PC. Some suppliers have a once off charge for the static ip address and some provide it free. Best results are achieved if upload speed is a min of 1GB. The higher the upload speed the better the pictures and the faster the load time.
Cost wise expect to pay anything from €1000 to €2500. Price around.
NB: ensure the installer is licensed with the PSA ( private security authority).
Ron just curious my broadband provider UPC have a dynamic system. I asked them about the static ip and they said it was only dynamic available. Yet my cctv installer was able to set up the cctv so that i can view online and on my smart phone with no problems
Could this be a problem down the line? (pardon the pun):cool: 0 -

Yes if your ip changes you will no longer be able to view from outside your network unless you find out the new IP you have been assigned and use that
kind of like your address on the internet, if UPC changes your address and you send something obviously it wont be delivered. Thus is the case with Dynamic IP
Static just means you keep the one IP all the time0 -

Uses of dynamic addressing
Dynamic IP addresses are most frequently assigned on LANs and broadband networks by Dynamic Host Configuration Protocol (DHCP) servers. They are used because it avoids the administrative burden of assigning specific static addresses to each device on a network. It also allows many devices to share limited address space on a network if only some of them will be online at a particular time. In most current desktop operating systems, dynamic IP configuration is enabled by default so that a user does not need to manually enter any settings to connect to a network with a DHCP server. DHCP is not the only technology used to assign dynamic IP addresses. Dialup and some broadband networks use dynamic address features of the Point-to-Point Protocol.0 -
