With an ever increasing interest in broadband CCTV, Transmission speeds and quality of service Vision Networks have added a few hints, tips and tricks to help CCTV integration and improve internet service speed.
CCTV systems with a network port can often be setup to allow remote viewing, some systems offer a free or paid for hosted service. Many CCTV recorders now offer software for both Android, Windows CE and iPhone. The majority of recorders allow connection from Microsoft internet explorer via a direct X downloaded plug-in.
Security should always be foremost in your mind, and the use of complex passwords is highly recommended.
The "upload" speed from your system is the more important as this limits the speed the recorder can send the images, most broadband solutions give a much slower upload speed typically peaking at 500 Kbs. Guernsey now supports ADSL 2+, in order to take advantage of this service your broadband router needs to support this format. Your router manufacture will often offer firmware updates to keep your equipment up to date with the improving infrastructure. We are assuming if you are connecting CCTV you have a broadband router installed and this is hard wired to the recorder. Wireless or USB connections will greatly affect performance.
Connect CCTV locally
The first step is to make sure you can view your CCTV system locally via your network. As part of the setup you will need to assign an IP address to your recorder, along with sub net and gateway. This often has the additional benefit of being able to synchronise the clock to an NTP (net time protocol) server via the internet. Chances are you will need internet explorer 7 or above and also you will need to allow the downloading of unassigned active X control (see internet explorer security settings)
The most complicated part..
(a) Most broadband connections have a dynamic IP address, this means it changes from time to time. A simple get around is to use a dynamic DNS service, this option is often explained with your CCTV recorder or can be configured on your router. This will enable your router WAN IP address to be tracked, allowing you to always find home.
(b) In order for your router to "route" your request to view the CCTV a port forwarding needs to be set up in your recorder. For example if your recorder is viewed using port 80 (normal internet explorer port) you need to tell your router to pass on any port 80 requests to your recorder IP.
Improve Broadband Speeds
Make sure your broadband router is running with the latest version firmware.
Ensure you have the correct ADSL filters in place on all telephones and your cables are in good order.
Broadband routers with proper network connectivity generally give better performance over USB.
Later generation versions of windows normally give better internet performance.
Shared systems will soon use up the available bandwidth, some routers offer additional configuration for resource sharing.
