The remote control, as an accessory of the conference camera, is the most frequently used remote control. So what types of remote controls are there on the market? Only by understanding these types can we better filter which remote control is more suitable for us. In general, the remote controls on the market are divided into the following three categories according to the signal classification:

1.Infrared remote control

Advantages: The main principle of this remote control is to control the device through infrared light, which is invisible light. The infrared light is then converted into a digital signal that the control device can recognize, and this type of remote control can be remotely controlled from a long distance.​​

Disadvantages: However, due to the limitation of infrared rays, the infrared remote control cannot pass through obstacles for remote control or remote control the device from a large angle, and the anti-interference ability is not good.
2.2.4GHz wireless remote control

Advantages: With the increasing popularity of wireless remote control in remote controls, the 2.4G remote control signal transmission method can effectively solve the shortcomings of infrared remote control, allowing you to remotely control the TV from all angles in the house. And it is a 360-degree operation without dead ends. All-round three-dimensional coverage is the advantage of the 2.4G remote control, and it is also the best type of remote control at present.

Disadvantages: The cost of 2.4G is too high, and electronic products are usually worth every penny. The same 11-button remote control, 2.4G remote control is twice as expensive as the infrared remote control. So this kind of remote control is usually only entrenched in the high-end market.

3.Bluetooth remote control

Advantages: The advantage of the Bluetooth remote control is that it can achieve a completely independent signal transmission channel by pairing with the device. Such a link channel can avoid interference between wireless signals of different devices, but this is only a 2.4GHz technology. Replenish. That is to say, a more perfect effect is achieved, which plays the role of a double-protected signal transmission.

Disadvantages: As far as the current situation is concerned, the Bluetooth remote control also has some defects. For a common example, when we use this type of remote control for the first time, we need to manually pair the remote control with the device, and device operation may occur. Delayed condition, and then need to refresh.
