كيف تختار نظام المراقبة بالفيديو؟ 5 نصائح

Decided to install a video surveillance system? Don’t know which one to choose? Do not know what is WDR and DNR and afraid to buy a system with a fuzzy picture or a system that in half a year will burn out night illumination? Our 10 tips for choosing a video surveillance system will help you, also for your convenience we will tell you about the 3 most popular video surveillance systems on the market!

Tip one: Buy equipment as a complete set from one store. In many companies it is cheaper to order a ready-made kit than to buy all the same things separately. Also check the composition for the presence of all necessary elements: Cameras, brackets, mounts, cables with connectors, DVR, power supplies and hard disk for recording. Many companies in order to cheapen their offer do not include in the basic sets of hard drive, which means that you will only have online viewing without the recording function and in order for you to start recording you will have to find a store that sells specialized for video surveillance systems hard drives and also independently install it and format it by disassembling the recorder.

Tip Two: Choose a system between 2 and 5 megapixels. The more megapixels the better the shooting quality, systems with less than 2 megapixels have too low shooting quality. Systems with more than 5 megapixels are still quite expensive and the quality parameter does not correspond to the price parameter. The most popular systems are 4 or 5 megapixels, because at a relatively low price they give a good clear picture.

Tip three: Choose cameras with branded sensors. The matrix is 95% of the quality of your video surveillance system. In total there are 2 types of matrices – it is branded manufactured in factories of well-known companies, such as SONY or OMNIVISION and unbranded matrices manufactured in small factories in China, such matrices in the market unfortunately most. Unbranded matrix has poor picture quality with ripples especially noticeable at night shooting, as well as the risk of constant breakdowns due to the low quality of materials. From branded budget matrixes the most popular are the above mentioned matrixes of SONY and American company OMNIVISION. Also check with the store where you will purchase the system whether these matrices are original or a copy, if it is a copy, the quality will not differ much from the unbranded version.

Tip Four: Choose a system with motion sensors, WDR, DNR and LED night light. Motion sensors will save you budget on your hard disk and you can also receive notifications when the sensor is triggered on your smartphone. Without WDR and DNR functions, buying a video surveillance system is pointless, because without WDR you will have a backlight when light from the sun hits the lens and all faces will be black, and without DNR at night because of noise you will not be able to recognize faces even with high resolution of your cameras. LED night illumination is much more durable and will serve you for 10 years, unlike the standard based on R-5yh infrared diodes that will partially burn out by the end of the first year of use.

Finally, tip five: Look for the phrase: “Works with all types of any Internet" in the description of your chosen video surveillance system. After Roskomnadzor’s attempts to block Telegram in the summer of 2018, more than 95% of all installed video surveillance systems began to experience difficulty due to the blocking of IP addresses of cloud services. Some manufacturers fixed this problem at once, some did not fix it until now, which means that despite the fact that the system may be declared a remote viewing function in such a system it will either not work or will work with failures, finding a connection with the 4th, 5th time. Also if you do not have wired internet, check whether the system you choose will work via 3G/4G. And most importantly clarify whether the function of remote viewing is free, does not require a subscription fee function itself or the application on a smartphone, because this sin many manufacturers offer a price for equipment lower than their competitors, and earn their own on the mandatory non-costly monthly maintenance.

And now the top 3 most popular video surveillance systems on the market.
