What is a Security Camera?
For the moment the market offers a variety of video surveillance systems, which exemplify the rapid development of the industry. These security camera systems perform a wide range of tasks, from the surveillance on out to moving objects detection in a certain area inside the premises. Depending on the intended use, security cameras can have different versions, be fitted with different controls and data processing equipment. In our review we will examine the best security camera systems available on the market, explain you how to make the right product choice and what aspects to focus on when picking a security camera-equipped system.
It is worth noticing that the operation of many modern security cameras is based on a wireless Internet connection use. In case you do not have a Wi-Fi router that provides a reliable wireless connection see our wireless routers review, in which we give a piece of advice concerning the choice of an optimal router.
What Features to Compare
First, you must determine the tasks your surveillance camera system has got to perform, depending on which the correspondent installation type should be chosen (indoors, outdoors). Accordingly, you need to decide what kind of a security system is suitable for your needs: wireless or wired with one or several cameras. These aspects are described in Camera Type and Mounting feature.
The security cameras can be wired and wireless (data transfer, power supply), indoor security cameras or outdoor security cameras with different mounting options (wall, pedestal stand, combined). Cameras for outdoor surveillance are characterized by better case protection and designed for the use in different weather and light conditions.
Wired cameras connect to security system equipment via wires. This connection type allows for connecting to an existing home network or corporate network, as well as granting access to security cameras’ control and data from various local equipment, or remotely via the Internet. High reliability and security of video data transfer to the recording equipment are the advantages of wired connection. These cameras can be controlled, powered and used to transfer the video via a single cable while being insensitive to interference of mobile phones, Bluetooth-devices, wireless network equipment and car alarm systems.
Wireless security cameras transmit the signal to a recording device via a wireless connection (Wi-Fi, Bluetooth). IP cameras (a particular case of wireless cameras) broadcast video data not to the local video recording equipment but directly to the registered user's device on demand through an internet service (some models make it possible to record the video to the camera’s SD card). By using this type of security camera, you can get access to a video broadcast in real time from practically any location.
After that, you need to consider the Video Quality and Features. Camera shooting quality is governed mainly by the quality of the camera optics, which affects such quantitative indicators as video shooting resolution and a viewing angle. The higher the resolution the more detailed the resulting image is and the bigger the viewing angle the larger the area covered by a security camera is. The shooting modes supported by a security camera are also relevant, such as shooting in darkness, long distance filming, an automatic video recording start and user notification when the system detects motion in the field of security camera’s view (motion detection).
In conclusion, you should consider the feature of Control and Storage Device. This feature determines the type of security camera control, the software used for this purpose and the capabilities offered to the user. The parameters grouped in this feature determine the storage medium to store the camera shooting footage on and the method for accessing it.
