1. What is CCTV, and how does it work?
CCTV (Closed-Circuit Television) is a video system where cameras are used to monitor and record an area. The footage is stored on DVRs or NVRs and can be viewed live or played back later.
2. What is the difference between DVR and NVR?
A DVR (Digital Video Recorder) works with analog cameras, while an NVR (Network Video Recorder) is used with IP (internet protocol) cameras. NVRs typically offer better video quality and are easier to install, especially with wireless options.
3. Can I access my CCTV cameras remotely?
Yes, most modern CCTV systems allow remote access through apps or web browsers. You can view live footage, review recordings, and control certain features from your phone or computer.
4. What is smart home automation?
Smart home automation lets you control home devices like lights, locks, thermostats, and appliances through an app or voice assistant. It can be used to enhance convenience, security, and energy savings.
5. How can CCTV be integrated with smart automation?
CCTV can be linked to your smart home system, allowing you to receive alerts, control cameras, and integrate footage with other devices, such as setting lights to turn on automatically when motion is detected.
6. Do I need Wi-Fi for a CCTV system?
Not always. Wired systems don’t need Wi-Fi for local recording. However, if you want remote access or use wireless cameras, an internet connection is required.
7. What is Power over Ethernet (PoE)?
PoE allows IP cameras to receive power and data through a single Ethernet cable, making installation easier and reducing the need for multiple cables.
8. How much storage do I need for CCTV footage?
Storage depends on factors like the number of cameras, video quality, and recording length. A typical setup may need 1TB for continuous recording of 4 cameras for around a week.
9. How long do CCTV cameras last?
With proper care, CCTV cameras can last 5-10 years. However, upgrading every few years ensures access to the latest features and improved video quality.
10. Are smart locks safe?
Yes, smart locks are safe and use encryption to protect against hacking. They can be a convenient way to secure your home and control access remotely.
11. Can CCTV be used to monitor indoors and outdoors?
Yes, there are CCTV cameras designed for both indoor and outdoor use. Outdoor cameras are typically weatherproof and built to handle temperature changes.
12. What’s the difference between motion detection and continuous recording?
Motion detection records only when movement is detected, saving storage and making it easier to review footage. Continuous recording captures all the time, ensuring no moment is missed.
13. Do smart cameras work during power outages?
Some smart cameras have battery backup options, but most CCTV systems will not function during power outages unless supported by a UPS (Uninterruptible Power Supply).
14. Can I automate lighting with my CCTV system?
Yes, with smart home integration, you can set up your CCTV to trigger lights when motion is detected, improving visibility and acting as a deterrent.
15. How do I ensure my CCTV system is secure from hacking?
Use strong passwords, regularly update firmware, disable remote access if not needed, and use a firewall or VPN for added protection.
