Code Grabber For Garage Doors, Barriers and Gates
Codegrabber Alpha
Barrier and gate capture is used when working with automatic security systems operating at a frequency of 315 and 433.92 MHz. The average range of these devices is 20-25 meters in good weather conditions.
Main operating modes:
1. Password selection.
2. Copy the code.
You can purchase a barrier on the company’s official website or by phone from the organization’s manager.

The barrier code grabber is equipped with special algorithms for adapting to systems from other manufacturers, which makes the device practically universal. It is powered by one 1.5V battery.
The device is equipped with an antenna 17 cm long, which in practice is often reduced by half (to 85–90 mm), without significantly reducing the range. You can purchase a barrier code grabber directly from the manufacturer through an official dealer.
Barrier signal capture
Barrier code grabbers are divided into:
1. Devices with an algorithm adapted to copy the security code. A device with this algorithm can bypass the trusted dialogue circuit. The principle of operation of the dialogue circuit is as follows: the key sends a signal to the receiving control unit. Then the request is processed by an algorithm for searching for a key among the stored devices. The receiving device sends a special request signal to the key, which is processed using a secret code. The processed code is returned to the receiving control unit and compared with the original request. After that, the car is disabled by the security system.
Advantages: high reliability, the system is very difficult to hack.
Disadvantage: high price.
2. Equipment working with static codes. These are the simplest security systems.
Advantages: ease of use and low price.
Disadvantages: It is very easy to hack such a security system.
3. A device that works on the basis of code substitution. The principle of operation of this device is based on intercepting the signal sent by the key to the alarm receiver. The device creates interference that allows the sending request signal to be replaced with its own code.
Barrier scanner
The basis of the barrier key scanner is that it is a master key, that is, a learning key. The device allows you to store about a hundred control panels of the security system in its memory.
The barrier code grabber is made in a plastic case, equipped with a telescopic antenna up to 20 centimeters, has five buttons and a joystick for navigating the device menu. Compact size and information displayed on an LCD screen. The board has a built-in special RF ID module designed to select a security code for tags and cards for intercoms and barriers at an operating frequency of up to 125 kHz.
The menu is compiled for convenience in Russian and English. It is possible to set a password when turning on (set your own PIN code), as well as manually set the operating frequency.
Code grabber for barriers and gates
The universal code grabber Gate is equipped with AM modulation. These are the standard operating frequencies of the device. The monochrome LCD displays 4 lines. For convenience, each cell can be manually assigned a name.
Main operating modes:
1. Scanning and recording codes/requests.
2. Automatic password selection.
Used when a key or remote control is lost.
3. Radio signal jamming mode.
4. Code replacement. Universal for automatic security systems operating at a frequency other than the standard one.
5. Card and tag copying mode at 125 kHz.
