The modern replacement for old analogue CCTV cameras is the wireless internet CCTV, also known as IP CCTV. The wireless CCTV system that is internet enabled has a great advantage over old system. You can see your property from anywhere in the world. You can see live images and video of your business property or your house, from wherever you are, just with the help of internet.
The technology has come in the market, but not many people know how to best use to. In order to get the best out of your wireless internet CCTV system, we must also look at the requirements and features that a router would need in order to be used successfully with the wireless system. There are a lot of things that goes into deciding your router for the wireless internet CCTV.
Broadband Type and Router Compatibility
You can have a broadband service that can come through either a phone line or a satellite CCTV box. In case the broadband service is through a phone line, you will require an ADSL modem/router also known as the DSL modem/router. Alternatively, if your broadband comes from your cable supplier, you would then require a cable router. This is another box that plugs in to your cable box.
The router part of your DSL modem/router or the cable router is basically the same. Manufacturers just make the DSL or cable version of the router that has the same features.
Router Features for Wireless CCTV System
- The router must be set up so that the port number, a special code, is allocated to the camera. When you type the IP address and the port number in the internet browser from any system, the router sees the port number and passes the message to the camera. Without this facility, it will not be possible to view your property through internet.
- With broadband suppliers changing your IP address at will, DDNS i.e. dynamic DNS support comes in. It helps you to use a third-party service to link a domain name you your IP address. The router’s DDNS feature makes sure that the router will tell the DDNS provider about your current IP address. Thus, even if your IP address changes, you can contact your camera with the domain name of the DDNS.
- Having your router remain connected is very important. This is important especially when you go out on a vacation. You don’t want to find that you cannot connect to your camera because your router disconnected due to power failure. In case of power cut, the DSL line or cable may drop for some time. Not many home routers are able to handle this, but with technology, new routers are able to reconnect by themselves after power cut. The router is able to sort itself out once the power is back and provides you hassle free access to your camera from anywhere in the world.
Thus, a router is an important device that enables you to monitor the security of your home and business’s wireless cctv systems from anywhere in the world.
Choosing Routers for Wireless Internet CCTV
Wireless Internet CCTV, also known as IP CCTV, is the modern replacement for old analogue CCTV cameras, and has the great advantage that you can see your property, live, from wherever you happen to be, using the internet. Now that the technology has become popular in homes and businesses, people need to know how to get the best out of it. In this article, I want to look at the minimum set of features that a router needs in order to be used successfully with wireless CCTV.
First, a quick note about types of broadband and router compatibility. Your broadband service is likely to come through your phone line or perhaps via a satellite CCTV box. If it’s through a phone line, you will need an ADSL modem/router, sometimes called a DSL modem/router. The modem part of the box is what talks to the phone line. On the other hand, if you have broadband from your cable supplier, you need a cable router. This is not the cable box itself, but another box that plugs into your cable box. The router part of a cable router or a DSL modem/router is usually the same, with many manufacturers making cable and DSL versions of what is essentially a router with the same features. Now, let’s take a look at the features you will need to get the most out of your wireless internet CCTV system:
- Virtual Server/Port Forwarding. This just means having the ability to set up the router so that a special code known as a port number is allocated to the camera. When you open an internet browser window and type in the URL or address of the camera, you add this special port number onto the end of the camera’s address, (e.g. for port 8765, you would type “http://:8765″) and when the router sees the port number it knows the message is to be passed to the camera. Without this facility, you would not be able to see your property over the internet.
- DDNS Support. It stands for Dynamic DNS and is used where the address of your home or business on the broadband system, known as the IP address, is changed at will by the broadband supplier. Most DSL broadband services have changing IP addresses, also known as dynamic IP addresses. Say you have an IP address of 91.103.218.59 (they tend to look like this) today, with dynamic IP addressing it could be something different tomorrow. This means you would never know what address to use to access your camera over the internet, and that is where DDNS support comes in. Basically, you use a third party service to link a domain name to an IP address. This service is provided by a separate DDNS provider and can be free, e.g. dyndns.com. The router’s DDNS feature means that the router makes sure it always tells the DDNS provider what your current broadband IP address is. Therefore, even if the IP address changes, you can always contact your camera by using the same dyndns address, e.g. “http://myipcamera.dyndns.com:8765″.
- Keep alive or auto-reconnect feature. This feature is all about making sure the router stays connected. You may have a power cut, or the DSL line/ cable connection may drop for a few moments. In these scenarios, you want the router to sort itself out. Earlier models of home router did not handle this well, and even today some can still be bought that don’t reconnect after a power cut or especially a broadband fault. The last thing you want is to go on holiday and then find you cannot log into your camera because a power cut several days ago left the router disconnected, so this is important.
- Encryption. Most routers these days offer some sort of encryption, usually known as WEP or WPA. WPA is stronger and preferable. Encryption is simply encoding the messages on your wireless network so that they cannot be intercepted easily. Make sure you get a router that offers at least one type of encryption that your wireless internet CCTV cameras offer. For example, it is no good getting a router which only does WPA encryption if your cameras can only do WEP.
