Presence
One of the most important management tools for optimal human resources management is the traffic control system or traffic registration device. It is very important to closely monitor and manage the entry and exit of personnel in order to evaluate their performance in optimizing and reducing costs. Using attendance software to output data for use in the payroll system is one of the other reasons for the necessity of purchasing a time clock. Maybe at first glance, buying this system is a kind of cost imposition, but gradually and over time, by reducing costs and improving the performance of personnel, not only the purchase cost will be compensated, but it will also bring many benefits.
The facilities of the presence and absence
According to the type of technology, all types of watchmaking devices (face, fingerprint, iris or card recognition) provide different facilities and capabilities. Some devices support multiple authentication methods at the same time, and some only support one authentication method. In some examples, in addition to recording and managing entry and exit time, it is possible to determine body temperature, face recognition with a mask, or determine the level of access to different parts using the access control module.
The most important criteria for selecting the presence of the presence and absence
Identification algorithm
Currently, there is a great variety of attendance and absence devices in the market of these products, and this variety is in terms of the method of authenticating people's identity or the mechanism of traffic registration by the system.
In fact, this product identification algorithm is the factor that creates the difference of the devices. Currently, traffic registration is done using identification algorithms such as code, biometric technology, and sometimes in combination. But it is important to mention that the first and most important criterion for choosing and buying an attendance device is the place where the device is supposed to be used.
Control and registration of traffic on attendance devices take place in three general ways:
Suitable presence and absence for offices
Another environment where the use of time clocks or time attendance devices has been well received are offices. One of the most important features of offices is having specific check-in and check-out times and fixed work shifts.
Therefore, in these environments, the use of fingerprint and facial recognition attendance devices are the best options, which with a simple attendance and attendance software that comes with the device, can accurately control and monitor the movement of personnel and, as a result, calculate personnel salaries and wages more easily. reduce costs.
Of course, it is important to mention that the number of attendance devices should be considered proportional to the number of personnel in the collection so that the speed of information recording increases, otherwise, considering that the biometric identification algorithm requires a time of about seconds, may lead to the formation of long queues to register traffic.
The method of discharge or connection to the device
The main role of the attendance device in the traffic automation system is to register the traffic, which requires the transfer of information on the attendance software in order to perform calculation operations and adjust salaries and wages.
Therefore, you should choose a device with a method of communication or information discharge according to your work environment. Among the ways of downloading information, we can mention the use of USB port, network cable and WIFI. In some examples, the only way to download information is through a network cable and USB port, and some examples, in addition to the above two methods, benefit from the ability to connect to WIFI to download information.
The speed of the device and other accessories
The speed of the attendance device can depend on the memory of the device and the type of processor used in the device. Therefore, if you need an attendance device in a large group, be sure to pay attention to the processor specifications of the device so that you don't face problems. Because in a large complex that has a large number of personnel, a weak processor can disrupt the movement of personnel and create long queues, which is actually a waste of useful work time.
One of the other factors that you should pay attention to while buying an attendance device is having an external battery or an external battery support, this option is one of the important things so that the device can still be used in the event of a power outage. be But one of the things that you can pay attention to while buying is the ability to use the device as an access control or traffic control device.
The device installation location
One of the things that should be taken into account while buying the time attendance device is the place to install the device. Maybe many people don't pay much attention to this, but you should keep in mind that the installation location of the device is especially important for facial recognition devices.
For example, if the face detection device is exposed to strong sunlight in an open environment, it can cause problems in the face detection because this strong light can lead to the formation of a dark image, which makes the detection difficult. make In fact, the angle of light can affect the efficiency of face recognition. However, this problem has been solved to some extent in the product series of Nanotime SEMI OUTDOOR 7000 attendance and attendance device and SEMI OUTDOOR 7000 model.
Also, installing the presence and absence device for facial recognition in places with low light can also cause problems for face recognition if there is no infrared camera. Therefore, before buying the attendance device, it is necessary to determine a suitable place to install the device. One of the things that should be paid attention to in the right place for installation is installation in a place where some traffic is not recorded many times so as not to cause problems in your calculations.
