IP Network Surveillance System or IP Network CCTV is an advanced surveillance and security system that uses network technology to transmit video and images from cameras to display and storage devices. This system is characterized by its ability to continuously monitor and control places and areas, which contributes to increasing security and protection. Network (IP) cameras are used in this system, and enable high-definition video recording and transmission over the network, allowing access to remote viewing over the Internet. The cameras can be connected to a local network within the building or to a public network via the Internet for control and monitoring from anywhere in the world. An IP network surveillance system is useful in many areas, such as residential security, businesses, public utilities, government organizations, and industrial facilities. This system helps to identify accidents and unwanted activities, and facilitates tracking and documenting events and incidents to provide a safe environment and effective control of property and people.

Online Lock System is a kind of smart lock system that enables remote control and management of locks via the Internet. This technology is used in doors, interior doors, safes and other places where a secure access and lock system is required. Traditional locks are transformed into smart locks by adding electronic components such as sensors, electric locks and electronic modules. These components are connected to the Internet or an internal local area network, allowing authorized persons to control and unlock the lock through smartphone applications or through a web interface on computers. With the online electronic lock system, users can manage access flexibly and efficiently. Permissions can be assigned to each individual user, which means that you can decide who can unlock and when.

A Public Audio System (PA Audio System) is a system used to transmit audio and advertisements to a large audience in a specified area. This type of system is used in public places such as airports, stations, malls, schools, theaters, stadiums and other public facilities. A public sound system is characterized by its ability to clearly communicate sound to a large audience, making it ideal for public announcements, alerts and instructions in a public place. The system is controlled remotely using different speakers and sound sources, allowing for easy and efficient management of audio and announcements. Public sound systems are used in many environments, including busy public places, shopping malls, schools, stations, hospitals, hotels, stadiums, religious venues, museums, galleries, government facilities, and other public spaces. A public sound system enhances users' experience and contributes to better communication and overall communication in large areas.

Voice over Internet Protocol (VoIP) is a technology that allows the transmission of voice and voice calls over the Internet. Instead of using traditional landline or mobile telephone networks, voices are converted into digital data that is sent over the Internet in the form of data packets. When this data reaches the desired destination, it is converted back into sound that can be heard by the receiver VoIP technology is used in a wide variety of communications applications, from regular telephone calls over the Internet to video calls, voice messaging, and mobile phone services over the Internet. VoIP is an innovative and efficient technology that facilitates communication and communication on a global scale, as it builds on existing Internet infrastructure and allows cost savings and improved voice quality. VoIP has become increasingly popular lately due to its many advantages, including lower costs of Internet calls, ease of use, ability to place calls from anywhere with an Internet connection, and the ability to combine voice, data and video into a single application. In this way, VoIP technology contributes to improving the communications experience and providing flexible and reliable means of communication for individuals and companies alike.

A General Radio Management System (GRMS) is a control system used to manage wireless communication networks within large buildings and facilities. GRMS allows users to easily communicate and coordinate within the building using cordless phones that are distributed in the various locations. The system relies on wireless communication technology to cover all parts of the building with a strong network, which makes communication easy and effective for users in all places within the building. GRMS is an effective communication solution in large buildings such as hotels, hospitals, malls, and government buildings, where employees and workers can easily move and communicate while performing their tasks. This technology provides many benefits, including the ability to communicate instantly and quickly, improve coordination between work teams and employees, and improve work efficiency within the building. GRMS technology is also an effective alternative to traditional fixed telephones and contributes to improving the quality of communication and communications in large institutions and buildings.

I apologize for the misunderstanding. My General Explanation A Building Management System (BMS) is an integrated system used for the overall control and management of many systems and equipment within buildings. This system aims to improve the efficiency of use, comfort and safety within the building through central control of various equipment and systems such as air conditioning, lighting, security, water and others. A building management system enables effective and integrated control of all aspects of the building, which helps in improving the overall performance of the building, saving energy and resources, and improving user comfort. The system can be programmed to adapt to building needs and usage requirements, facilitating more efficient and flexible building management. Building management system is an important tool in the smart management of modern buildings and large facilities, as it contributes to improving energy and environmental efficiency and reducing operational and maintenance costs, which leads to a better experience for users and residents and achieving higher levels of comfort, safety and sustainability.
