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.

What is WDR - Wide Dynamic Range?

WDR is the abbreviation used for Wide Dynamic Range. WDR is the technology used on professional security cameras, where there is need to balance brighter and darker surveillance areas. WDR is actually the difference in lighting. It is clearly seen, when recording entrance, where bright outdoor light is merged with dim indoor light, or when the area has large glass windows. Cameras using Wide Dynamic Range technology are able to record clearer details in low light scene, while making sure that the highlights don't get blown-out, and as a result having natural looking shot.

WDR technology is commonly used in surveillance cameras and in some medical applications. In an area with extremely bright and dark parts or in back light situations when the light comes from the back of a person, standing in front of a big window, a camera without WDR would produce an image where objects in the dark areas are hardly visible. Wide dynamic range solves this issue by applying techniques such as using different exposures for different objects in a scene for making objects in both bright and dark areas more visible and clearer. 

At www.koacctv.com high quality professional security cameras with true WDR are offered to re-sellers and installers, some of the cameras You can find below.
