Analog cameras are used in enterprises for video surveillance of objects. Modern models are made with sensitive lenses. Most chambers are made with high conductivity. The resolution of the device is quite different. Also, the main parameters of the cameras should include the viewing angle and focal length. Additionally, the frequency of the device is taken into account. To understand analog type cameras in detail, it is recommended to consider the standard modification scheme.
Camera layout
The standard scheme of an analog camera involves the use of a contact lens, a module and a control unit. Lenses are applied low and high sensitivity. Video outputs are installed in different series. Thyristors for models are suitable with a frequency of 400 MHz. Additionally, it is important to note that the adapters for cameras are installed with regulators.
Model Types
There are different types of analog cameras. According to the type of installation, the models are divided into internal and external modifications. The first option is the mostsuitable for office buildings. They use matrices of low conductivity. In this case, the viewing angle does not exceed 12 degrees. If we consider external cameras, they have a wide lens. Most devices use a wired module. The maximum viewing angle for models is 160 degrees. By design, rotary and projector modifications are distinguished.
Internal cameras
Indoor analog CCTV cameras are made with racks for installation. Modern models are distinguished by high resolution, they use a wired modulator. The focal length of devices starts from 3.5 meters.
How to connect an analog indoor type camera? Some models are installed directly through the line conductor. Expanders for modifications are selected in a positive direction.
The sensitivity parameter of the internal cameras is approximately 5.5 mV. Most devices are made with a PP video output. It should also be noted that there are modifications with transient modulators. The operating frequency of the internal cameras is about 450 MHz. Most models are made with a protection system. It should also be noted that the devices differ in noise level. In some cases, cameras are connected via channel adapters.
External cameras
External cameras stand out with a wide viewing angle. They have better security systems. Such modifications are often installed at the entrance of office buildings. Models are also often used beforeshops. Their viewing angle, as a rule, does not exceed 230 degrees. Some models are made with a contact adapter on the video output. The resolution setting in the cameras is different. Most models work from a modulator. Additionally, it is important to note that there are cameras with multi-channel adapters. The operating frequency parameter in the devices reaches a maximum of 450 MHz. Lenses are used in different classes. Apertures are installed in the P40 series.
When choosing a modification, it is important to pay attention to device modes. Night photography requires a special filter. It should also be noted that there are models with high light sensitivity. Connection of wireless cameras is carried out through a linear adapter. Comparators for devices are matched by a low directional network. If we consider a simple model with a short rack, then it is fixed through one module. Modern models are produced with AC output. Thyristors are used to connect them. These items are sold with or without a rectifier. It is also worth noting that there are modifications on wired controllers that close on the module. To connect such a modification, a special contactor is installed. In this case, the camera is connected to the computer. To configure the equipment, go to the device menu. In this case, a lot depends on the operating system.
PTZ cameras
Rotating analog CCTV cameras include a multi-channel matrix and a conventional lens. The module is used with a thyristor. Connecting an analog cameramost often through a switch. If we consider the standard model, then it has a resolution of 780 by 500 pixels. Some devices are manufactured to support the CP format.
It should also be noted that the models have special movable racks. Drives are used only controller type. Some chambers are distinguished by low resistance. Rectifiers for them are selected for two outputs. To install the modification, you will need a contact expander, which closes on the power supply. A regular personal computer is used to set up the camera.
Scheme for connecting designed cameras
The designed analog cameras are allowed to be connected via a dipole modulator. The controller is used with one adapter. Experts say that the filter is used with a contactor.
If we consider wire modifications, they have a PP output. In this case, the adapter is used with an expander. It is also important to note that some models are connected only through a three-output contactor. In this case, the equipment is configured thanks to a personal computer. The standard model is adjustable via panel. Considering modifications on modulators, it is worth noting that they need to install a variable controller. The adapter for these purposes is used for three channels. A low-resistance expander will do to complete the circuit.
Best analog type camera
ActiveCam AC-TA461IR2 is the best analog camera that has been recentlyis in great demand. She has a high-quality lens that allows you to shoot video in high resolution. The matrix of the model does not consume much electricity. In addition to the advantages of the device, it is worth noting the good conductivity of the modification. Experts believe that the device is very easy to install. It should also be noted that the model has an excellent body. The filter in this case is of a photosensitive type.
Installation to a computer
Analogue cameras are connected via a computer using an adapter. In this case, much depends on the output of the panel. If we consider devices with a PK connector, they use a contactor without an expander. In this case, the camera is connected directly through a contactor. It should also be noted that the modification can be configured using the driver. Some devices are made with PE output. They do not fit the standard expander. It is more expedient to select an adapter with a transceiver. Most specialists use only wired modifications. If you install several cameras, then a receiver is used for this. Modern devices are produced for two outputs.
Connect via laptop
Through a laptop you can connect analog cameras of various types. If we consider projector devices, a transceiver is used for them. Rectifiers are installed with and without filters. It should also be noted that the cameras are mounted through modules. Speaking of channel modifications, it's worthnote that they use KE connectors. All this suggests that the standard connection module will not work.
In this case, only modifications with a dipole adapter can be used. In this case, the rectifier is installed with a wave switch. To configure the camera, you will have to go to the control panel. Next, it is important to detect a new device; for this, a scanning function is provided. After that, all that remains is to update the modification driver.
Using a 10V block
10V power supplies are only suitable for external cameras. Contact modulators are used to connect the modification. In this case, the controllers are installed with adapters of different conductivity. Modern devices are made with the release of the Republic of Kazakhstan. They have a standard lining.
It should also be noted that there are devices with a variable adapter. Cameras for such models are suitable only for the designed type. The rectifier itself is of a low-resistance type. Experts say that the thyristor is selected with a filament adapter. First of all, an expander is connected to the circuit. After that, the cameras and power supply are installed.
