Appendix C: IP Address, Subnet and Gateway

This section discusses Communities, Gateways, IP Addresses and Subnet masking

Communities

A community is a string of printable ASCII characters that identifies a user group with the same access privileges. For example, a common community name is “public.” For security purposes, the SNMP agent validates requests before responding. The agent can be configured so that only trap managers that are members of a community can send requests and receive responses from a particular community. This prevents unauthorized managers from viewing or changing the configuration of a device.

Gateways

Gateway, also referred to as a router, is any computer with two or more network adapters connecting to different physical networks. Gateways allow for transmission of IP packets among networks on an Internet.

IP Addresses

Every device on an Internet must be assigned a unique IP (Internet Protocol) address. An IP address is a 32-bit value comprised of a network ID and a host ID. The network ID identifies the logical network to which a particular device belongs. The host ID identifies the particular device within the logical network. IP addresses distinguish devices on an Internet from one another so that IP packets are properly transmitted.

IP addresses appear in dotted decimal (rather than in binary) notation. Dotted decimal notation divides the 32-bit value into four 8-bit groups, or octets, and separates each octet with a period. For example, 199.217.132.1 is an IP address in dotted decimal notation.

To accommodate networks of different sizes, the IP address has three divisions – Classes A for large, B for medium and C for small. The difference among the network classes is the number of octets reserved for the network ID and the number of octets reserved for the host ID.

IP200, IP300, IP100 specifications

SVAT Electronics has long been a trusted name in the field of surveillance and security, and their line of IP cameras, specifically the IP100, IP200, and IP300, exemplifies their commitment to quality and innovation. These cameras are designed to cater to various security needs, providing users with advanced features and reliable performance.

The SVAT IP100 is an entry-level model, perfect for users seeking basic yet effective surveillance. This camera boasts a 720p HD resolution, allowing for clear and sharp images. One of its standout features is its night vision capability, which utilizes infrared technology to capture footage in low-light conditions, ensuring 24/7 surveillance. The IP100 is also easy to install, with a user-friendly setup process that allows users to get started without any technical expertise.

Moving up the range, the IP200 offers enhanced functionalities suitable for mid-level security needs. This model provides 1080p full HD resolution, delivering superior image clarity. The IP200 comes equipped with motion detection alerts, which notify users of any unexpected movement within its field of view. Additionally, this camera features a built-in microphone, allowing for two-way audio communication, which enhances its usability in various situations, such as monitoring children or pets.

At the top of the line is the IP300, a high-performance camera designed for more demanding surveillance requirements. This model supports 4MP video resolution, ensuring that every detail is captured with stunning clarity. The IP300 also features pan-tilt-zoom (PTZ) capabilities, enabling users to remotely control the camera's viewing angles and zoom in on specific areas of interest. This flexibility is particularly useful for monitoring large spaces effectively. Furthermore, the IP300 incorporates advanced motion tracking technology, which automatically follows moving subjects, ensuring that nothing goes unnoticed.

All three models are powered by advanced technologies such as H.265 video compression, which optimizes storage space without compromising video quality. They are compatible with mobile apps and remote viewing capabilities, providing users with the convenience of monitoring their premises from anywhere in the world. Whether for residential security, small businesses, or larger commercial applications, the SVAT IP100, IP200, and IP300 cameras deliver quality, reliability, and advanced features tailored to meet the needs of modern surveillance.
