3 Reasons why to choose EXIR Technology

While looking through the features of security cameras, you could have noticed that having EXIR Infra-red lighting is listed as an advantage.

Conventional IR, integral to cameras, uses an array of individual LEDs which aren’t particularly focused to the lens pattern. This tends to result in a picture which has a circular pattern of brightness with more illumination at the center of the image.

Hikvision, the world market leader for security cameras and accessories for video surveillance has developed the EXIR system which uses a lens configuration to make the illumination pattern rectangular and more evenly dispersed. The EXIR IR system is used in some of TVI and IP cameras.


So, main benefits of EXIR technology are:

1. Highly efficient light source and enhanced LED light strength.Hikvision’s EXIR technology offers up-to 30% increase in illuminant efficiency, more than traditional LED array technology. Compared to a traditional light extraction of 750mV, EXIR offers 1050mV, resulting in stronger light for long-range visibility usage.



2. Rectangular-shaped lenses are used for better light usage. To make the most out of IR LED light, Hikvision EXIR produces LED light in the form of a rectangle in order to fit a screen’s normal size, which is 4:3 or 16:9, and it helps to improve LED utilization efficiency and reduce light pollution in the surrounding environment.



3. Objects are more evenly illuminated, thus avoiding the typical shortcomings of conventional lighting systems based on infrared array elements (too much light in the center of the frame and not enough on the edges).

7 Important Features Of Security Cameras

Considering buying a security camera? Want to know what is most important, what features the cameras should have? In this article we’ll discuss some of them, which make the camera better, more professional, more effective and worth buying.
Security cameras are an essential part of your home and business, and this is the case, when quality means safety.

#1 Video Quality

In the security camera business, the video quality produced and recorded by your system is very important. Now, security cameras offer at least 720p resolution, and many even offer as high as 1080p for recording and streaming. Some of the top surveillance systems on the market feature 1280x960-pixel camera resolution and more.

The main purpose of a surveillance security system is to capture or deter criminals when there is suspicious activity around the house, business, or personal items. When a crime does occur, a high-resolution camera can provide a clear and detailed picture of the criminal.

#2 Vandal-proof cameras

Vandal proof security cameras are equipped with a metal housing that prevents the camera from damage from vandalism, physical abuse or possible maltreatment. All homes or businesses should strongly consider vandal proof security cameras for their video surveillance system installation. Vandal proof security cameras are often utilized in high-security areas like warehouses, banks, airports, hotels, parking lots, and retail stores.







#3 Weatherproof Cameras

Weatherproof cameras feature at least an IP66 weather rating, which is a standard rating of protection offered by a camera’s enclosure. Each outdoor camera housing is constructed to keep out small particles such as dust, and is unaffected by a range of weather conditions including heavy rain and snow.


#4 Viewing Angle

Viewing angle is an important feature to consider when both purchasing and installing security cameras. The viewing angle will determine where you position the cameras and exactly how much they can see at a time.


For instance, a 180° megapixel camera could be used to monitor a parking lot adjacent to the building that it’s mounted on. Actually, this one camera could take the place of up to four analog security cameras.

A 360-degree fisheye and panoramic security camera provides 360° surround view without blind spots, and it is ideal for surveillance applications that require wide area coverage in a single view.





#5 Remote Monitoring / Web Access


This is not only a feature and a service that is just generally added to your overall video surveillance system, it’s also a way to manage and oversee your business from a distance. You’d better buy a camera that can be accessed via the Web. You’ll be able to see the yard, the front door or your workplace from the screen of your smartphone or laptop computer.

#6 Recording / Storage


A security camera that doesn't save or record what it captures isn't very effective, especially if you're hoping to prosecute an intruder. That's why most security cameras offer either local or cloud storage and sometimes, both.

#7 Low-Light Security Cameras / IR



Infrared security cameras capture video in low light and no light areas. IR cameras, or infrared cameras are also known as Night vision security cameras. Infrared cameras have IR LEDs positioned around the outer edges of the camera lens which gives the camera its Night Vision capability.

Dummy Cameras: Security or Illusion?


Have You heard of dummy cameras? Of course, as it is rather common to use them in surveillance purposes, when one cannot afford buying a real security system or security cameras. Dummy security cameras imitate the appearance of real cameras and there are cases when they really help to deter crime. Installing fake security camera is surely a better idea than having no security cameras at all, or trusting the property security to a dog.

 Nowadays, fake security cameras are available in different sizes, colors, shapes. In most cases they use the original housing. There are dummy cameras which have some features like a fake pan/tilt/zoom, or red lights which make the camera look more realistic and achieve better results. Of course dummy cameras have the advantages of being much cheaper, they don’t need any maintenance and in certain situations they are useful. But before buying a dummy security camera, you should review all pros and cons seriously, and make the right decision. You should understand, that when it comes to security and protection of what is dear to us, fake cameras are a great risk. 
In most cases burglars and criminals are capable of telling the difference between a fake and dummy camera at one glance. As the 80-90% property crimes are being planned beforehand, the cameras, burglar alarms and other deterrents are also checked beforehand. Always remember, that a real security camera is a safer bet than a fake one. Besides, when something bad happens to Your property or business, you will not have a surveillance footage, if you had have chosen fake security cameras. The use of fake security signs and stickers is also a bad idea, as it takes only a few minutes to google the company name and find out, whether your house is secured by that particular company or it is a fake.
It's not a good practice from a security point of view or, when used for business, from a business point of view. Besides, dummy cameras may mislead other people in that certain area of “Surveillance” into fake sense of security, thus resulting in potential liability issues for the location owner in case of accidents. 
Installing fake security cameras is a bad idea, especially when the property is located in high crime areas, if you have valuables, which should be well protected, and of course, if the well-being and security of your family members, employees or customers matters most. Modern CCTV market offers affordable security cameras and security systems, and one should realize, that this is not the case to save or go on budget. Anyway, Hikvision offers security cameras and security solutions which fit to any budget. Hikvision offers best quality for affordable price, and this is where it stands out in the market.
