They are typically less expensive than IP cameras and can be used with existing analog systems. However, the image quality is lower, and the footage is not as easily accessible as with IP cameras.

3. Wireless Cameras Wireless cameras are easy to install and can be accessed remotely from a computer or mobile device. They are suitable for indoor and outdoor use and are available in various designs, including dome, bullet, and box cameras. However, they are vulnerable to interference and hacking, making them less secure than wired cameras.

B. Camera Resolution Camera resolution refers to the number of pixels in an image. Higher resolution cameras produce clearer images, making it easier to identify individuals and objects. Most security cameras have a resolution of 720p or 1080p, but some cameras can capture images in 4K resolution. It is important to choose a camera with the appropriate resolution for the intended use. For example, a high-resolution camera is necessary for identifying license plates or facial features, while a lower resolution camera may be suitable for monitoring a general area.

C. Camera Angle and Lens The camera angle and lens determine the field of view of the camera. A wider angle lens allows for a larger field of view, while a narrower angle lens is suitable for focusing on specific areas. The type of lens also affects the image quality, with higher-quality lenses producing clearer images. It is important to consider the intended use of the camera when choosing the lens type and angle.

D. Night Vision Night vision is an important feature to consider, especially for outdoor surveillance. Cameras with infrared LEDs can capture images in complete darkness. The range of the infrared LEDs varies depending on the camera, with some cameras having a range of up to 100 feet. It is important to choose a camera with sufficient night vision capabilities for the intended use.

E. Storage and Recording Security cameras typically record footage onto a network video recorder (NVR) or digital video recorder (DVR). NVRs are used for IP cameras, while DVRs are used for analog cameras. The storage capacity of the NVR or DVR depends on the number of cameras and the resolution of the footage. Some cameras also have onboard storage, allowing them to function independently of an NVR or DVR. It is important to choose a storage solution that can accommodate the desired amount of footage.

F. Power Supply Security cameras require a power source to function. Wired cameras are typically powered by a Power over Ethernet (PoE) switch, which supplies power and data over a single Ethernet cable. Wireless cameras are typically powered by a battery or solar panel. It is important to choose a power supply that is suitable for the intended use of the camera.

III. Security System Integration

Security cameras are typically part of a larger security system that includes other components, such as motion detectors, door sensors, and alarms. Integrating these components can provide a more comprehensive security solution.

A. Motion Detectors Motion detectors are used to detect movement within a designated area. When motion is detected, the camera can be triggered to start recording or send an alert to the user. Motion detectors can also be integrated with lighting systems to deter intruders.

B. Door Sensors Door sensors are used to detect when a door is opened or closed. They can be integrated with security cameras to trigger recording or send an alert to the user. Door sensors can also be integrated with access control systems to prevent unauthorized entry.

C. Alarms Alarms are used to alert users to potential security threats. They can be triggered by motion detectors, door sensors, or other security components. Alarms can be integrated with lighting systems to increase visibility and deter intruders.
