Answer: A smart home is a residence equipped with devices that automate and control home functions, often remotely via a smartphone app or voice assistant. These devices include smart lights, thermostats, security systems, and appliances that can be interconnected and controlled for convenience, security, and energy efficiency.

Answer: Smart home devices typically communicate using wireless protocols like Wi-Fi, Bluetooth, Zigbee, or Z-Wave. These protocols allow devices to connect to a central hub or directly to each other, enabling control and automation. Some systems also integrate with voice assistants like Alexa, Google Assistant, or Siri.

Answer: Yes, like any internet-connected device, smart home devices can be vulnerable to hacking. To minimize risk, use strong, unique passwords, enable two-factor authentication where possible, keep your devices and apps updated, and use a secure Wi-Fi network. Some users also opt for devices that offer advanced security features like encryption.

Answer: Many smart home devices are designed with energy efficiency in mind. For example, smart thermostats can learn your schedule and adjust heating or cooling to save energy, and smart lights can be set to turn off automatically when no one is in the room. Additionally, energy monitoring features in some devices allow you to track and manage energy usage more effectively.

Answer: If the internet goes down, most smart home devices lose remote control capabilities via apps, but many will still function locally. For example, smart lights can be controlled manually, and smart locks often retain basic functionality. However, cloud-dependent features like voice control or external camera access may not work until the internet is restored.

Answer: To enhance smart home security, follow these steps: Use strong, unique passwords for all devices and accounts. Enable two-factor authentication. Keep firmware and apps updated. Use a guest network for smart devices, isolating them from your main network. Regularly monitor device activity for any unusual behaviour.

Answer: To control smart home devices with your voice, you need a compatible voice assistant like Amazon Alexa, Google Assistant, or Apple Siri. After setting up your devices in the voice assistant’s app, you can use voice commands to control them. For example, you can say, "Alexa, turn off the lights," or "Hey Google, set the thermostat to 22 degrees."

Answer: The storage duration of CCTV footage depends on the system’s storage capacity, the number of cameras, the resolution of the footage, and the recording method (continuous vs. motion-activated). Typically, footage can be stored for anywhere from a few days to several months. Once the storage limit is reached, the system will usually overwrite the oldest footage.

Answer: Yes. Remote viewing can be achieved via a smartphone, tablet, or computer. This requires the system to be connected to the internet. Users can access live footage or recorded videos through a dedicated app or web portal.

Answer: The number of cameras needed depends on the size and layout of your property, as well as the areas you want to monitor. Typically, you would need cameras covering entry points (doors, windows), driveways, and other vulnerable areas. A professional security assessment can help determine the optimal number of cameras for comprehensive coverage.

Answer: The resolution of CCTV cameras determines the clarity of the video footage. Common resolutions include 720p (HD), 1080p (Full HD), 4MP, 5MP, and 4K. Higher resolution cameras provide clearer images and more detail but also require more storage space. 1080p is often sufficient for most residential and small business applications.

Answer: Yes, it is generally legal to install CCTV cameras on your property for security purposes. However, there are privacy laws to consider. For example, cameras should not be pointed at areas where people expect privacy (like bathrooms or bedrooms) and should not infringe on neighbors' privacy. It's also important to notify visitors that CCTV cameras are in use.

Answer: Some CCTV cameras are equipped with microphones and can record audio. However, the legality of audio recording varies by location and often requires consent from those being recorded. In many places, recording audio without consent is illegal, so it’s important to check local laws before using this feature.

Answer: Motion detection is a feature in many CCTV systems that triggers recording or alerts when movement is detected within the camera's field of view. This helps conserve storage space and makes it easier to review footage, as the system only records when something happens. Motion detection can usually be customised for sensitivity and specific areas of interest.

Answer: DVR (Digital Video Recorder) systems are typically used with analogue cameras and record the footage onto a hard drive. NVR (Network Video Recorder) systems are used with IP cameras and record footage over a network. NVR systems generally offer better video quality, easier installation, and more flexibility compared to DVR systems.
