7 Tips for Protecting Home Automation System from Hackers

There is no need to discuss how useful home automation systems can be, as beyond any doubt, they make our life easier, safer and incredibly convenient. Due to smart home automation systems, home owners can manage all home devices from one place, thus also maximizing home security level. Automatically lock and unlock doors, turn on and off the lights being in another place, make a video feed of your home available on your mobile phone, and even include thermostat control.  Anyhow, many systems are also vulnerable to home automation hackers. They are very often able to break in to change settings, access video feed, what is more dangerous, unlock doors of the house or garage so that they can easily access your home. If homeowners just follow these simple rules, their home automation systems will be more protected against hackers’ attempts to take control over their property.

#1 Set password

Always, in any case, set a password. Use strong passwords, weak passwords are easy to guess. The best choice are strong passwords with numbers, letters, and characters.  Also avoid using real words or names.

#2 Change your password regularly:

Even if hackers have already revealed Your password, regular change can save the situation.

#3 Secure Your router:

In case the router is secure, it makes all the connected devices strongly protected. It would be excellent if homeowners chose routers which have strong security features. Also, make sure you change the default password to a new, stronger one while installation.

#4 Choose reputable brand:

It is always tempting to order some cheap system from unknown brand, but you should always have in mind that this can cost a lot more, than a trusted product from a well-known brand. They will also give more practical instructions against home automation hackers.

#5 Consider having a separate network for your home automation system:

It is a good idea to create multiple access points on the router for two different networks.  One will serve for your computer and mobile devices, and the second will be used for your home automation system. So, even if a hacker reveals your network password from your mobile or laptop, they still won’t be able to access your home automation system.

#6 Check the camera logs.

Many security cameras give access to users to the history of which IP addresses have accessed to the camera feed. Checking the camera logs regularly will help to make sure no one has accessed your home surveillance system. If you notice any suspicious behavior, immediately change your password and contact your security provider.

#7 Don’t use public Wi-Fi

Using home automation applications on public Wi-Fi can easily give access to hackers. Turn off the Wi-Fi and use secure mobile data instead before using a home automation application. Using an encrypted mobile website if your system offers that feature is also a good idea.

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).

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.

7 Signs, that Your House has been Targeted for Robbery

According to FBI statistics, every 15 seconds a house is being robbed in the USA. 9 out of 10 burglaries are usually planned beforehand, so there are a few signs, which are indicators that Your house is being watched for not-so-good-purposes. Here are some situations You should watch out.

1. There are strange marks on the fence, on garage, on the house itself. If You are sure, that its not Your kids' art, then consult the police officer as soon as possible.

2. You have spotted a strange person walking slowly in Your neighborhood and observing Your house. This is to be taken into consideration carefully, because he might just turn out to be a lost passer-by.



3. A vehicle that you haven't seen before on your street: The first warning sign is a vehicle parked and unattended for a long time or at random times near your home. It doesn't belong to your neighbors or anyone you know in the neighborhood.

4. In general people have an appointment set in advance when a cable repairman or TV installer is stopping by to fix or service your equipment. So if a handyman, workman, or anyone else comes to your home unannounced, take warning.

5. Another knock at the door by a stranger who asks to use Your bathroom or wants a glass of water. It is possible, that he would be a random passer who is just in need of anything, but anyhow, better safe than sound, keep an eye on him.

6. Your locks, window locks or garage door/window is mysteriously broken. You should hurry to fix them and check Your alarm system.

7. There are promotional materials at the front door, like visit cards, promo-offer catalogs, sticky notes on the door. Usually burglars put all these at the front door, to check if homeowners are at home, or not.


Many people think that wasting money on a home security system is useless and they try to take the responsibility of keeping their home safe by not having a security alarm system, and only after a burglary or another accident realize, that investing on a security system is vital for their home protection.  Keep Your property secure and safe with security system. That's the best deterrent for burglars.

What is an IP camera?

What is an IP camera, and what are the main differences between an IP camera and a CCTV camera?

IP camera, or Internet Protocol camera is also called Network Camera, and they are widely used for residential and commercial purposes, offering the user high quality.

IP camera needs a static IP address for the router and other network devices to identify and connect with it. In case of a dynamic IP address that keeps changing randomly every time the camera is connected to the network, a fixed URL via Dynamic Domain Name Service (DDNS) must be set up.

While CCTV cameras transmit one-way analog data with the help of coaxial cable to the DVR, and then it is converted to digital data, IP cameras are able to send and receive, that is to stream digital video, PoE - a system that passes electrical power along with data on an Ethernet cable., and in this case there is no need in analog to digital conversion. IP cameras stream the video directly to the NVR, a Network Video Recorder. The main advantage of IP camera over CCTV is that the camera captures and delivers a higher quality video. Additionally, IP cameras capture a much wider field of view than comparable analog cameras. As a result, the cost of IP cameras is much higher than that of analog ones.

IP cameras either have wired or wireless connections, and are used both indoors and outdoors, during the day and at night.

There are two kinds of IP cameras:

Centralized IP cameras

These cameras require a central NVR to store the recording, handle video and alarm management.

Decentralized IP cameras

Decentralized IP cameras don’t need a central NVR, and the video is processed at the source, as the cameras have recording function built-in and can thus record directly to any standard storage media, such as SD cards, hard disc, or a server.

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.

Security Cameras as Crime Deterrent

We have already discussed the importance of using CCTV cameras in public places, and first of all the role of CCTV cameras as crime deterrent. In this article we will find out, what do we mean by saying crime deterrent?

The most important thing is, that the cameras are an effective tool in reducing crime if deployed the right way. Correct installation, monitoring and maintenance of the cameras plays a key role in crime prevention. The use of CCTV Cameras can be a solution to issues like vandalism, drug use, drunkenness, racial harassment, sexual harassment, anti-social behavior.

It is very important to let the society know about the use of security cameras at certain area. The offender must be aware of the cameras' presence. There should be put special signs for cameras, and as different studies and statistics show, crime rate has decreased in areas, where warning signs were put. Actually, it is not so important to arrest the criminal, but it is of more importance to prevent the misbehavior. Sometimes it is even possible that fake cameras could achieve the same preventative aim as active systems. Anyhow, there might be cases, where hidden cameras should be used, because of some really important security matters, or when the police is carrying out an investigation.

Video evidence not only helps police investigate crimes, it can be used as evidence in court.

Internal cameras are meant to keep the employees honest and identify those who are not. Internal cameras can also prevent shoplifting and armed robbery and they can identify those who commit crimes despite the cameras.

An integrated security system that includes surveillance cameras is a must have nowadays, especially in areas which have high criminal rate.

So, Video Surveillance aims to:

1. deter Crime

2. increase the confidence in public safety

3. increase the property protection status

4. help police with its investigations

5. prevent social misbehavior

Different Types of CCTV cameras, Main Features.

Very often we are asked “What camera should we choose?” “What is the difference between Dome & Bullet Cameras?” etc. In this article we will describe every type of camera briefly.

CCTV cameras come in various types, styles, and configurations, and it is very important to choose the right CCTV camera for the right location and application.

Dome Cameras

In general, Dome Cameras are used for indoor security and surveillance applications. The cameras are named so, because of their dome like shape. The "dome" shape makes it difficult to tell the direction that these cameras are facing, and thus are ideal for deterring criminals. Dome cameras can be fitted or embedded to ceilings to conceal the majority of camera’s casing.

Bullet Cameras
Bullet cameras are easy to recognize by their thin and cylindrical design. There are also classifications of Ultra Bullet distinguished by their smaller size and cheaper price. These type of

cameras are ideal for surveillance of a large area, like large retail stores, houses or other business.

Unlike dome cameras, bullet cameras are easy to tell, where the camera is pointing and what it is recording.

Day/Night Security Cameras


Day&Night security cameras usually operate in two modes: colour for daytime, when light levels are high and black and white for viewing in low-light environment. A true Day/Night camera will have an “IR-cut filter” inside the camera. Once the IR cut filter is removed from the surveillance camera, it enables the image sensor to become sensitive to near-IR wavelengths, thus making it possible for the camera’s light sensitivity to reach down to extremely low light levels or even complete darkness.



Vandal-Proof Security 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.

You can also typically find vandal-proof cases that are designed to protect more sensitive cameras, giving you the protection that you need without having to go out and purchase a brand new camera



IP/Network Security Camera

An Internet protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which, unlike analog CCTV cameras, can send and receive data via a computer network and the Internet.

IP cameras, both hardwired and wireless, are easier to install than analog cameras because they do not require a separate cable run or power boost to send images over a longer distance.

C-Mount CCTV Camera

C-mount CCTV cameras have detachable lenses to fit different applications. Standard CCTV camera lenses can only cover distances of between 35 and 40ft, therefore with C-mount CCTV cameras, it is possible to use special lenses, which can cover distances greater than 40ft.

PTZ Security Cameras



PTZ Security Cameras allow you to control the pan, tilt and zoom operations of the camera lens remotely. PTZ Cameras have the ability to move up, down, right, left, and even zoom.

HDTVI cameras

Image result for HDTVI cameras HDTVI (High Definition Transport Video Interface) is latest HD analog video solution. HDTVI can provide HD video up to 1080P resolution at real time. Different from HD-CVI and HD-SDI solutions, HDTVI can support long distance video transmission.

HDSDI cameras

HD-SDI CCTV cameras, also known as HD security cameras, are capable of capturing video surveillance footage at 1080p resolution (1920 x 1080 pixels). These high definition surveillance cameras must be used with an HD-SDI surveillance DVR.

Hidden Cameras

A hidden camera or spy camera or security camera is a still or video camera used to record people without their knowledge. The camera is "hidden" because it is either not visible to the subject being filmed, or is disguised as another object.
