Internal surveillance cameras

Domestic camcorders have been popular for many years, their use is almost ubiquitous. It is difficult to imagine an area of ​​human activity in which video surveillance and video recording would not be applied. Surveillance cameras help in the detection of crimes and even allow you to prevent them. These gadgets are adopted by private security agencies and law enforcement agencies. Since the area of ​​their use is quite wide, it is quite natural that the market offers a variety of models. In order not to get lost in the wealth of choice, you should pay attention to several important aspects.

Application area

Home video camera is a universal device that can be operated not only in a residential area.Conventionally, the use of internal surveillance cameras can be divided into several areas.

1. Apartment Video Camera. Such devices often have a small body to make it easier to disguise them from prying eyes.
   
2. Home Video Camera. A private house needs protection no less than apartments in an apartment building. The private sector most often falls under the views of intruders. A cottage can be a target for thieves, so you should think in advance about the security of your home. Best of all this will help video surveillance.
   

3. Video camera to give. A country house, especially located in poorly protected communities, is a rather attractive target for intruders. Often thefts occur during the autumn-winter season, when most owners do not come to their plots. In this case, a model with a motion sensor is best suited, which, if necessary, will notify the owner of the attempt on the property (a corresponding notification will be sent to the smartphone).
   

4. Video camera in the entrance. The disadvantage of a multi-storey building is a large density of accommodation.Often there are neighbors leaving the garbage on the landing or teenagers committing acts of vandalism. For a quick suppression of these actions and their prevention, it is best to install a surveillance camera in the stairwell. A camera that can shoot in a dark room with IR illumination will cope with such tasks.
   
5. Video camera to the store. A great opportunity to further secure your property. The fact of theft, captured on video, is essential evidence of guilt in court. For operation in the mode of a large flow of people, it is better to use models with a color matrix. Color recognition helps to establish more details than the traditional black and white image.
   
6. Office video camera. Sometimes it is imperative to know what the employees in the office do. To prevent the facts of theft and leakage of documentation or other intellectual property, it is best to equip the office space with a video surveillance camera. This will help in disclosing the details if such a nuisance happens. In addition, the camera can serve as an additional incentive for employees, because their behavior and level of discipline in the workplace will be recorded.
   

Classification

Video surveillance cameras are divided according to the shape of the case and the type of information transfer.

By form factor

The dome shape of the case is most suitable for indoor use.. In appearance, such a camera resembles a hemisphere; sometimes there are models protected by a special “glass”. This form factor is also called a ball in a glass.

Cabinet models - A very interesting version of the video surveillance system. These cameras are not supplied with mounts and brackets. Such devices are often bought for a specific task. The dense, well protected case can be placed without problems and on the street. Inside the model easily fits productive filling. But this is not the most common option for indoor video surveillance. Explained it pretty large size the camera itself. The larger the size of the case, the harder it is to hide it from the eyes of others.

Miniature video camera - A great option for the implementation of hidden video.The case is most often made in the form of an elongated oblong cylinder or a small square. All necessary fixtures are supplied. Installation is carried out indoors only. This type of video camera is very popular due to its size, which makes it easy to hide the device from the office staff, or from outsiders eyes.

By type of information transfer

Here we can distinguish two types - wired and wireless. The first type is cameras that work only with all the necessary wiring. In most cases, this is a twisted pair, and more recently, coaxial cable ranked first. Every day, optical fiber, which is a more modern and reliable source of information transfer, is becoming increasingly popular.

A significant disadvantage is difficulty in pulling the cable itself. Sometimes you have to rebuild the walls, making new recesses in them for the cable. Another problem is cable masking. In addition, sometimes in the room just nowhere to hide bulky wires. The advantages of wired data transmission are its relative availability and the transmission distance of the signal from the optics to the receiving unit.

Wireless cameras are a modern data transfer protocol used by Wi-Fi, Bluetooth and IP cameras. They are not tied to bulky wires, there is no need to pull tens of meters of cable. The only thing required is power supply. At the same time, the signal transmission distance is significantly reduced. In addition, there is a binding to the router and the signal repeater. If somewhere fails, the camera immediately stops broadcasting.

It should be noted that such models require much more human intervention than their wired counterparts. In addition, the price tag for wireless devices is much higher.

Useful features

If the model supports write to memory cardthen it is a good option to save on the wire broach. After all, you can bypass the signal transmission to the hard disk, located in the receiving unit. The slot for memory cards is usually located on the case itself. It is convenient and practical, but not in all cases. The camera with recording on micro SD is a good find for those who know what they want from a gadget.

Home surveillance cameras need the most motion sensor. It is necessary where the room is empty for a long time.The more movements in the frame, the more will be the positives. It is very convenient when setting a cottage or a country house for long-term security.

Some models allow you to view the broadcast online using IP technology or P2P. This is extremely important in order to test the motion sensor for a false positive factor.

HD support relevant for color cameras. Most of all, this technology is used in shops and offices, where the greatest importance is attached to details, or it is required to quickly recognize a person. The higher the resolution of the lens, the better the picture that the camera transmits. To date, the HD format has become quite common, and some manufacturers who want to keep up with the times, are introducing support UHD, QHD in their models. At first, attention should be paid to this option, since it is associated with the quality of the written material.
