CCTV cameras are usually wired and need a constant power supply. Surveillance cameras can be run on batteries which means they can be placed anywhere without worrying about wires.

A CCTV provides continuous monitoring and recording, scalability for large areas, and integration with advanced security features. A security camera is more affordable, easier to install, and flexible for small-scale monitoring.

When choosing a security system, make sure you consider the purpose and requirements needed, camera types, resolution and image quality, night vision performance, field of view and connectivity, and storage.

Most wireless hidden cameras, including Wi-Fi cameras, can transmit signals up to 300 feet in a direct line of sight. Longer distances can be achieved by using higher powered transmitters or high gain antennas.

Not all security cameras require Wi-Fi. Some cameras can use LTE plans instead and others are not connected to the internet, but rather record onto local storage such as hard drives.

If you use Wi-Fi security cameras, you can only use them where a signal connects back to your Wi-Fi router. Exterior walls block and degrade the signals which can cause your cameras to disconnect and not show any video.

The most common CCTV cameras on the market include 2MP (1080p), 4MP (1440p), 5MP (1920p) and 8MP (4k/2160p).

As the resolution increases from 1080p to 4k, the image quality improves significantly meaning 4K cameras capture the most detailed and clear images.

A good quality camera will include high resolution video, strong infrared night vision, wide angle lenses, motion sensors to get active notifications, and a sturdy weatherproof housing.

Like any other connected device, security cameras are vulnerable to unauthorized access, hacking, and data breaches.
