Choosing CCTV security cameras involves several tough choices, owing to the variety of camera designs, styles, and features available. The variety is intended to cater to the unique home and business security needs. For this reason, property owners must ensure they understand what they need to achieve by installing a surveillance system, as this will guide them in making the right choices.
Factors to consider when choosing CCTV Cameras
1. IP Cameras vs. Analog Cameras
The latest trends in home and business security have CCTV cameras as the preferred choice for consumers. The use of analog systems has been on a steady decline over the years, and it is likely that they will become extinct very soon. However, it is possible to convert analog cameras to work in IP-based CCTV Systems. Consumers that had already invested in analog systems may thus, choose to upgrade their systems, instead of abandoning them altogether, in favor of the new IP CCTV Systems.
On the other hand, individuals and businesses could decide to install IP Cameras, which have the distinct advantage of being able to digitize video internally, before transmission to the NVR for storage or live viewing. The analog cameras can only capture raw video and send it to a DVR for encoding and storage.
2. Fixed Cameras vs. PTZ Cameras
Fixed CCTV cameras can only focus on one view, depending on the position and direction they are facing. For this reason, these cameras have a narrow field of view. PTZ (Pan-Tilt-Zoom) cameras on the other hand, can focus on different views, regardless of their positioning. The cameras have an electronic mechanism that physical adjusts the camera direction and focus, and thus, enables the cameras to cover wider fields of view and zoom in on far away objects.
3. Standard Cameras vs. Infrared/Thermal cameras
Standard CCTV security cameras are ideal for surveillance in environments with constant lighting. These cameras cannot function properly in dim-lit environments or places where the lighting conditions are unstable. Therefore, consumers have two options, namely, to provide external lighting to enable the standard cameras to work in poor lighting, or install either, Infrared or thermal cameras.
