In the early 2000’s, the market was flooded with pre-built CCTV systems. Most of these box systems which originated from China were seen as the best during that time. However, with the advent of new technological progressions in optics, CMOS and DSP technology, many of these systems have become inadequate and do not offer maximum security surveillance even on simple installations.
When it comes to installing an efficient CCTV system, the selection of cameras to be used is very important. It is also good to factor in the room or location they are required to monitor. Light, environment and climatic conditions and speed of the objects which the camera will be capturing are some of the things you consider.
The following are tips to help you select the most suitable CCTV camera for your system:
Indoor CCTV Cameras
Indoor CCTV cameras are manufactured in various forms and sizes. The three important specifications to centre on are:
Resolution – Indoor cameras are generally used to track and/or record. Therefore, good quality indoor needs to have not less than 520 lines for a better resolution.
Lens and optics – An indoor CCTV camera should be able to focus or zoom into a tiny area. This will enable it to record facial shots which you can use as legal evidence where necessary. However, such shots should be recognizable and printable.
Blend with the environment – Indoor CCTV cameras come in different shapes and sizes and range from bullet cameras to domes. Also, there are camouflaged models which look like fire sprinklers, motion detectors and smoke alarms. Thus, you need to buy an indoor CCTV camera that will match well with your setting.
Spy Cameras are a set of cameras employed and camouflaged while in action. They are miniature but there are some that are of standard sizes and which can be kept in ordinary items like clocks, teddy bears, smoke detectors and various types of fittings. Spy cams are the most popularity attributing to their low prices and the technological improvements that have led to their enhanced picture quality and also the built-in DVR systems.
PTZ is an acronym for pan/tilt/zoom. PTZ are CCTV cameras that have a remote direction and a zoom mechanism. These cameras are very handy in circumstances where the user wants to trail a person or object keenly. Besides, they can be pre-set to spot faces or motions and trail them in the field of view. Some of the improved ones can function in a security guard mode, where the camera can automatically perform a series of commands such as panning, tilting and zooming so as to cover a wider area.
