Controlled Access System

  ·        Revolving doors seem like glass flaps in a cabin which is going to revolve while people are passing inside or outside. The good thing is that entry and exit at same time is possible with automatic revolving doors. ·        Revolving doors cannot be classified in turnstiles. It can be classified in pedestrian gate categories. ·        They have aesthetic and slim body which is made with stainless steel or aluminium and combined with tempered glasses. ·        The body of revolving door is usually cylinder shape. This oval shape is tinged an elegant appearance. ·        Indication led lights have been on some of revolving doors for guidance. For more information, visit Optima Engineering How does a revolving door work? ·        There are photoelectric sensors on the door cabin which i...

  ·        There are two separate mechanism on the double turnstile, each of them is for per passage. ·        Double Full Height Turnstiles often use ratchet mechanisms to allow the rotation of the stile in one direction allowing ingress but preventing rotation in the other direction. ·        A lock up arm ( pawl ) is used to locking at the double full height turnstile mechanism. ·        Solenoids push or pull the pawls. ·        A drive spring provides the double turnstile arm to return its correct position when passage occurs. Drive spring mechanism has a spring inside its housing used to store mechanical energy. If this spring is compressed more than desired, force applied to turnstile arm rotating force will increase. ·        Shock absorber provides the smooth operation of the double t...

  ·        It is also called in different forms like; swing gate turnstile, cylinder swing turnstile, swing barrier turnstile, swing barrier, flap barrier, flap gate, glass line, VIP turnstiles, rotary gate, rotary automatic swing gate etc. ·        Automatic swing turnstiles are used to controlled at pedestrian entrances. ·        Swing barriers are very common near the other turnstiles because materials entrances ·        It is possible to see swing turnstiles at commercial centres, university, governments, private sector buildings etc. ·        Swing gate turnstiles may be preferred for handicap access. Because the flaps open the passage automatically. For more information, visit Optima Engineering. How does a swing gate turnstile seem? ·        Swing gate turnstiles seem like a glass flap ...

  ·        Swing Gate has a push button console which is placed to operate it. ·        Kind of Access Control Systems, card reader systems, remote control systems can be connected to operate the swing gates. ·        Basically, the hydraulic power unit pumps hydraulic oil to the pistons and pistons pulling the gate leaf to open or pushing the gate leaf to close. ·        Electro mechanic actuators have warm gear mechanism to open and close the gate leaf. ·        In case of power failure; it is possible to open and close it. Most of swing gate mechanism has a clutch system to release motor from the gears. When the gears are released from motor, the gate can open or close easily with man power. If the system is hydraulic, there is manual hand pump. For more information, visit Optima Engineering What are Swing Gate benefits ...

  Under vehicle inspection system captures and monitors underside image of the vehicles with a highresolution color/monochrome industrial cameras. System specifies suspicious objects after under vehicle scan process and takes them into a frame on the monitoring screen. In general, area scanning and line scanning cameras are used on the UVIS (Under vehicle inspection system) market. Now, we will talk about the technical specitications and advantages&disadvantages of these two type of cameras.  For more information, visit Optima Engineering. Both area scan and line scan cameras are preferred for machine learning in the industry. Line scan camera is a strip that quickly captures one row of pixels at a time as the camera is moved over an object or the object is being moved under the camera. In constrast, area scanning camera (also called regular camera) takes still photos of a specific two-dimensional area. The important difference between these two camera types is whether the...

Hidden gate turnstiles, also known as "speed gates", are generally used in places where entrance / exit control is made such as commercial centers, offices, schools, stadiums, subway, train and bus stations. In this blog post, detailed information will be given about the functions of hidden gate turnstiles Access control systems such as card readers, finger readers, face recognition systems can be integrated into hidden gate turnstiles. These systems can easily communicate with the turnstiles thanks to their relay outputs (dry contact). Speed gate are equipped with many functions to control user’s motions. Some of these are listed below:  For more information, visit Optima Engineering. Alarm function number 1: (double pass with single permission) Let’s say that there is a hidden gate turnstile and this turnstile has card reader to control entrance&exit access logs. When users scan their access card to card reader, they will have a single permission. If two users try to pa...

  The first thing to consider when choosing license plate recognition systems is; "License plate recognition systems" and "license plate recognition cameras" don’t have the same features. Therefore, knowing these concepts well will be useful for choosing a license plate recognition system.  For more information, visit Optima Engineering Basically, the purpose of a license plate recognition system is to be able to perform license plate recognition under different conditions. For example, the best license plate recognition system should be able to perform license plate recognition from vehicles moving at different distances, at different speeds, in environments with different illumination levels. In addition, these systems are capable of defining more than one plate at the same time. Different from these, some security cameras can be converted into a "camera capable of plate identification" with software and hardware added later. However, great performances ...
