Below are some steps to keep in mind when you plan to Buy Security Cameras Online.
Know what you want:
You need to know your budget while buying security systems. Either you need a wireless or a wired security system. Also, do you want an outdoor and/or indoor CCTV system? Would IP cameras work out for your space? Do you want 2, 8 or 16 camera system?
Select the Camera Type:
Wired: As the name itself suggests, wired camera system has data cables that run through the space in which you are planning to set them up. Data cables are connected from the recording device to the screens where the footage gets displayed. You need professionals to install the wired camera system. And this definitely increases the initial installation costs of the wired systems. The one advantage of the wired system is that they are not subjected to interference and hence there is no data loss. Also, wired surveillance won’t have the risk of getting hacked or it won’t get affected by any bad weather conditions or frequencies.
Wireless: Wireless cameras are in great demand and prevalent among the homeowners. They are relatively small in size and easy to install even for people with moderate technical understanding or skills. They can be placed anywhere within the range of wireless frequency and can be concealed easily. As long as it stays within the receiver’s range, they can be easily repositioned. This camera does not need cables to connect them. It is less expensive in comparison to the wired one. It is user-friendly and offers crystal clear video footage as well as precise audio quality. One of the flaws of this system is that they are liable to signal loss or interventions. Also, they are vulnerable to getting hacked as it is an internet enabled system.
IP (Internet protocol) cameras: IP cameras or webcams is another option in the pool of security cameras. You just have to connect your camera device to the computer’s router and you are good to go. It’s one of the advantages is that it allows you to access the cameras from any remote location over the internet. Also, it provides recording options like NVR (Network video recorder) or recording straight to your computer. Moreover, it offers secure data transmission through authentication and encryption methods.
Image Quality:
Security cameras generate images using Charge Couple Device/ CCD or CMOS chips. Low price CCTVs generally uses CMOS technology, hence produces poor quality images/videos and has poor light sensitivity. CCTV camera which uses CCD technology produces high-quality audio/video data. Normally, the size of the CCD chip is 1/4″, 1/3” or 1/2”. Consequently, higher the quality of the image, higher is the price.
Color:
It is recommended to opt for black and white CCTV system if you are going to place them in areas with low light conditions. The color camera should be considered for indoors which have ideal lighting conditions. Nevertheless, many homeowners use color camera systems for outdoors as well as indoors. For night vision, many high-resolution color cameras use an IR cut-filter which enables recording in places having little to no light. Also, as they use an infrared light (sensitive to the human eye) source to light up space, they can be hardly detected.
Recorder:
The best option to record videos from the CCTV device is Digital Video Recorder (DVR) which tapes the data onto hard drives.
