The cost of buying and installing a camera in a house varies depending on factors like brand, features, quantity, and installation complexity. Consulting with an Interior Designer in Greater Noida can provide a more accurate estimate tailored to your needs. Basic indoor security cameras can start from a few thousand rupees, while high-resolution outdoor cameras with advanced features can range from several thousand to tens of thousands. Installation costs may also vary, depending on whether professional installation is required and the complexity of wiring or mounting. Integrating cameras into a comprehensive home security system may involve additional costs for equipment and setup.
