Environmental Monitoring: Some modern systems include sensors that can monitor temperature, humidity, and air quality. This enables more complete situational awareness.

Installation and Maintenance: Ensuring Optimal Performance

Proper installation and regular maintenance are crucial for ensuring the optimal performance of these systems.

Professional Installation: For complex systems, professional installation is recommended to ensure proper placement, wiring, and configuration.

Regular Maintenance: Cleaning lenses, checking connections, and updating firmware are essential for maintaining image quality and system reliability.

Secure Network Configuration: Securing the network and changing default passwords are crucial for protecting against unauthorised access.

Storage Management: Regularly reviewing and managing storage space is essential for ensuring continuous recording.

FAQs

How much storage do I need for my security camera footage?

Storage needs depend on recording resolution, frame rate, and the number of cameras. Cloud storage plans offer varying capacities, while local storage requires hard drives. Higher resolutions and continuous recording demand more space.

Can security cameras work without Wi-Fi?

Yes, some cameras can record to local storage (like an SD card or DVR) without Wi-Fi. However, remote viewing and cloud features require an internet connection.

What is the best location to place security cameras?

Key entry points (doors, windows), driveways, and vulnerable areas are ideal. High vantage points offer broader coverage. Ensure cameras are protected from weather and vandalism.

How do infrared (IR) cameras work?

IR cameras emit infrared light, which is invisible to the human eye. This light reflects off objects, and the camera captures it, creating a black-and-white image in low-light or no-light conditions.

Are wireless security cameras secure?

Wireless cameras can be secure, but it depends on the security measures implemented. Strong passwords, encrypted connections (WPA2/WPA3), and reputable brands are essential.

Can security cameras detect motion through glass?

Most standard motion detection sensors won’t work through glass. However, some advanced cameras with AI object detection may be able to recognize movement patterns that suggest a person is present, even through a window.
