Default gateways serve an important role in TCP/IP networking. They provide a default route for TCP/IP hosts to use when communicating with other hosts on remote networks.
Gateways, also called protocol converters, can operate at any network layer. The activities of a gateway are more complex than that of the router or switch as it communicates using more than one protocol.

The following illustration shows the role played by two default gateways (IP routers) for two networks: Network 1 and Network 2.

In order for Host A on Network 1 to communicate with Host B on Network 2, Host A first checks its routing table to see if a specific route to Host B exists. If there is no specific route to Host B, Host A forwards its TCP/IP traffic for Host B to its own default gateway, IP Router 1.

The same principle applies if Host B is sending to Host A. Without a specific route to Host A, Host B forwards any TCP/IP traffic destined for Host A to its own default gateway, IP Router 2.

IP-Surveillance GXP 3610_HD



In today’s environment close observation of a person or group, especially one under suspicion is utmost important. Video surveillance is a vital tool for protecting people and property around the clock. The increasing availability and, thus, lower cost of higher-quality cameras makes improving the effectiveness of video more affordable.

 For a long time video surveillance was something mainly used by the government and large, wealthy companies; something you only saw in movies. Now you can see video cameras everywhere you look, whether you’re grabbing a quick bite at a fast-food restaurant, stopped at the intersection (hopefully not as you coast through a red light!), or walking up to your neighbors’ front porch. Video surveillance has become a necessity for small business owners, and is becoming more prevalent for home owners as well.

My reason for writing, however, is not to discuss the reasons for the rise of video surveillance system, but to examine three benefits of having a video surveillance system.

1) Acts as a deterrent to crime
The first benefit to having a 
video surveillance system is that it acts as a deterrent to crime. Seeing a camera, or a signage warning of cameras, can be unnerving to a would-be criminal.

2) Apprehend a suspect when a crime occurs
Another benefit of having a video surveillance system is the ability to apprehend a suspect when a crime occurs

3) Improve productivity of employees
Another major benefit of having a video surveillance system is improved productivity in the workplace (and at home). Many business owners’ primary motivation for installing a video surveillance system is not the threat from without, but the threat from within. About employees who routinely “steal” an employer’s time, by not doing what they are paid to do when they are paid to do it? At home security cameras can help you see if your children are home when they are supposed to be, and whether they are safe or not.

The GXV3610 series is a powerful tool in this regard. It is weather-proof Infrared fixed dome HD IP camera of outstanding performance and quality. Its advanced ISP (Image Sensor Processor) powered with state-of-the-art auto-exposure/auto-white-balance algorithm and a high quality lens, ensures high fidelity video quality that matches digital still camera color grade in a wide range of light environments.


The GXV3610 series is a powerful network camera for professional surveillance application in both indoor and outdoor environments.
