roduct Introduction

 

ST-605SZ integrated wireless video instruction transmission system adopts frequency modulation microwave mode to transmit the audio/video signal and receive RS485 signal (control the rotation of camera, lens, lights and rain strip) from the control center. The system features long transmission distance, good stability, and may adjust the digital display via video frequency and set up the frequency rate by the computer; it is waterproof and especially suitable for application in the field and under the bad environment. The system has several bands for selection: L (1.0-1.7GHz), Ku (10.7-15GHz), the receive frequency is 227-233MHz, it has good anti-interference, and it realizes real-time and clear image transmission with a distance of 5-10 kilometers. The system boasts good performance and price ratio.

 

Note:

Band: L, Ku

Distance: 5 kilometers, 10 kilometers

Model: ST－605SZ (L), ST－605SZ (Ku)

The distance of different model is not same; the customer should pay attention to that.

L (1.0-1.7GHz), Ku (10.7-15GHz)

ST-605SZ has waterproof function and may adjust the frequency and effectively avoid the interference frequency; long bandwidth (1.1-1.7GHz, 10.7-15GHz), wide adjustable range, small power and less personal injury; Additionally the system has transparent interface and the connection is similar to the wire monitor system; it adopts the common electric interfaces (BNC, AV), 220V AC power supply, DC12V power may be customized. In order to meet the actual condition, the working frequency is usually confirmed by the user according to the actual application (video frequency: 1100-1300MHz, 1300-1500MHz, 1500-1700MHz, it may be freely combined within 200MHz; instruction frequency: 227-233MHz, it may be set by the software); in order to ensure the microwave transmission, please avoid any barrier (building, tree or metallic bracket) between the transmitter and receiver; the equipment is especially applicable to long distance transmission at the open field, such as coastline, trans-river, road, oil field, mine and forest fireproof, it is a good complementation to the wired monitor system sometimes. The longest distance can be up to 5-10 kilometers, it’s easy to install and no cable is needed, it greatly reduces the cost, and much time can be saved. In accordance with the requirements, ST-5A-ZS (outdoor wireless cradle instruction controller) is equipped to realize the remote control to the camera, cradle head, rain strip and light, only one wireless cradle head instruction controller is required in one system.
