  • You can get the kit delivered to your home or collect it from the store, giving you more freedom and control over the installation.
  • With professional installation, ‌schedule and block your time for technicians to arrive, making you vulnerable to delay.
  • You are left alone to handle the issues occurring during the installation, while the professional installation comes with on-site support during the setup and activation, which could be useful for elders.
