Installing CCTV cameras might seem straightforward, but many people make critical mistakes that reduce system effectiveness. One common error is poor camera placement—placing cameras too high or too low can lead to blind spots. Another issue is ignoring lighting conditions; glare or darkness can affect image clarity. Failing to secure the network or leaving default passwords also puts your system at risk. Always use professional installers when possible, and ensure your system is regularly maintained and updated. A good installation ensures your security system works as intended when you need it most.
