Video surveillance in shops is today the most widely used video surveillance. The increase in the number of robberies and robberies, but also the intensification of scams requires an effective response. It is in shops that video surveillance has proven its effectiveness by proving to be particularly effective. Deterrent, preventive and curative, it is very rare today to see an establishment that is not equipped with a video surveillance system and Security Cameras in Chicago. What type of video surveillance camera to install in a business? Which system will offer you the most complete protection?
Install visible and dissuasive cameras
In your store, you want your cameras to be seen as early as possible and be able to act as a deterrent before an act is committed. They must be highlighted, on a bare ceiling or at face height. Dome cameras are effective when it comes to deterrence because you cannot detect the direction in which they are filming.
Install vandal-proof cameras
CCTV systems in stores are often targeted by robbers who want to deactivate their target's protection beforehand, but also by individuals who only degrade the cameras.
Choose wide-angle cameras
In the case of a robbery or theft, the important thing is to be able to detect very quickly what is happening in the field of each camera. Their fields must therefore be wide enough to limit dead spots and maximize the chance that the act will be detected in time. Reduced field cameras can also be installed in the annex, but only to monitor a certain point, such as the cash register for example.
Install a quality recorder
The last thing you want to find out after a robbery is that the images recorded by your cameras have not been recorded. So be sure to buy the most reliable and efficient recorder possible.
How does a video recorder work?
The video recorder of your video surveillance system is at least as important as its cameras. Without it, no image is saved or saved. Its quality, its good functioning as well as its correspondence with your video surveillance system must be perfect. To choose your recorder correctly, you must understand how it works. This article explains the role of your recorder vis-à-vis your cameras, and therefore of your protection.
The recorders function as a database which recovers the flow of images and videos transmitted by your cameras. These images are received in digital format and will then be stored for a predetermined time.
It is once the stage of receiving images has passed that things get complicated. There are two types of recorders: DVRs and NVRs. It is the way of recording and storing images that will differentiate these two systems.
DVR type video recorder
A DVR recorder compresses analog files sent by cameras, before storing them hard on a hard drive or storage device. The NVR will record digital images from the IP network.
We can therefore distinguish and summarize these two types of recorder by the way they record the image. We can also emphasize the fact that DVR recorders work with “classic” analog cameras, while an NVR recorder will work with IP cameras.
Once your images have been recorded and stored, your recorder continues to play an important role in your surveillance. Indeed, it also has control functions such as zooming, accelerating or slowing it down. Your recorder is therefore not just a storage box.
IP camera or HDCVI?
At the origins of the long list of choices that you will have to make before installing a video surveillance system, is the first distinction between IP and HDCVI cameras. This distinction, which is often little known and therefore little taken into account when purchasing a video surveillance system, is nonetheless essential. What are the specifics of these two systems? When should one favor one over the other? What are their advantages and disadvantages? This article attempts to paint a portrait of these two types of systems to help you choose the most suitable for your monitoring needs.
+ Cameras up to very high resolutions, limited by the visual rendering of the monitor screens.
+ Multifunction cameras (exchange of information, sending of alerts, messages, etc.).
+ Easy installation (wifi, PLC, etc.).
+ Very good storage management.
– Essentially wide angle cameras, few cameras with reduced field.
-Price for cameras higher than HDCVI.
-Price of the recording unit higher than the HDCVI.
+ Better zoom on image (cameras capable of filming further and more precisely).
+ The cost of cameras is low compared to IP cameras.
+ The price of recorders is also reduced.
+ Large storage capacity for images and videos.
+ Installation even easier than for an IP camera system.
-Cameras having no additional function to that of image capture.
– Cameras only fixed
The advantages and disadvantages of these two types of cameras make HDCVI a promising future. However, they are likely to be confined to indoor precision surveillance. IP cameras remain more effective when it comes to monitoring a large space such as a garden or a warehouse for example.
Discount cameras: are they worth it?
With the increase in the number of burglaries and robberies, Security systems in Chicago are becoming more and more common. More and more platforms are offering them, with or without after-sales service. With this democratization of video surveillance, also comes the appearance of a category of cheap video surveillance system of the discount type. These cameras respond to the sudden demand carried by an expanding market. Individuals and shop owners therefore find themselves in front of cameras which are sometimes worth very little money, and which a priori, fulfill the same role as more expensive cameras. This discount video surveillance has drawbacks which can cost you dearly.
Discount cameras are often sold without after-sales service. It is tempting to buy CCTV cameras that you install alone. However, no after-sales service will be offered to you. You will have to maintain your cameras alone, regularly change the parts, and constantly ensure the proper functioning of your cameras. This handling will cost you, in the end, more money than a good video surveillance system with a guarantee and an efficient after-sales service.
The insurance , are another problem when it was a question of discounts CCTV systems. Indeed, for you to be able to play your insurance in the event of a disaster, you must make sure that your cameras comply with the requirements of your insurance. Not all discount cameras are. Pay close attention to this aspect that is at least as important as the quality of your cameras.
The lifespan of your cameras is also relatively well correlated to the price you spend on your video surveillance system. Some discount cameras will work fine for a while, but will stop working at an inconvenient time, leaving you unprotected.
In any case, even if you decide, for economic reasons, to install discount cameras, make sure that they have a minimum image quality for the role you assign them.
