Having a good security camera system is a must for any business. Many owners already know about the basic advantages--security, employee accountability, and the like--but in recent years, a more advanced set of applications have emerged that can help boost the potential of a retail business to whole new level. These applications, of course, are retail analytics and retail optimisation, the successful implementation of which requires any who try it to get the right cameras for the job.
The first thing to note is that you're likely better off using a wired system instead of Wi-Fi, for several reasons. Wired systems aren't subject to the kinds of interference that can disrupt recording on wireless camera. Furthermore, they are less susceptible to hacking attempts and other forms of outside influence. In short, Wired cameras are a reliable standby that will provide you near-constant monitoring under a multitude of conditions where Wi-Fi camera systems will not. This leaves us with two options: wired analogue CCTV or IP camera networks.
CCTV Or IP?
Most already have some familiarity with analogue CCTV or closed circuit television. These cameras usually employ a point-to-point (P2P) or point to multipoint (P2MP) functionality that enables the camera to transmit to a select few monitors, and footage is stored at to a digital video recorder (DVR)).
IP (internet protocol) cameras differ in that they have the capability to transmit their data via the internet to multiple locations. Video from IP cameras can go to a centralised network which records and stores all footage (as opposed to the DVR), or it can simultaneously be stored on built-in media such as SD cards (in cameras that support this function).
In addition to where footage from the cameras is stored, you should bear in mind that in many cases, IP cameras are considered the more efficient option. This is because the transmission of footage to an IP address allows you to view your camera feed from multiple locations, and even mobile smart devices (one could theoretically do this with analogue CCTV as well, but the process is unduly complicated).
720P? 2MP? 3MP? 4MP?
Lastly, you'll want to consider the camera resolution. This refers to the total number of pixels in the image that are recorded and affects the overall image quality. This can range from the low end, 720P, all the way up to 4MP (megapixels). More pixels equals higher resolution and hence, a larger, cleaner image. Most IP cameras, incidentally, can deliver images at the higher megapixel resolutions, so keep that well in mind when making your choice.
