Fire-proof explosion-proof wireless mobile video transmitter

Fig

HD explosion-proof transmitter

MV2025P-3011A

 

○ The transmitter adopts a totally enclosed explosion-proof design, which has the characteristics of explosion-proof and shockproof

○ And comply with GB3836.1-2010 Explosive gas environment electrical equipment Part 1

○ General requirements and GB3836.2-2000 Electrical equipment for explosive gas atmospheres Part 1

○ Explosion-proof "d" explosion-proof standard, especially suitable for harsh outdoor environments such as chemical industry, oil field, mine, etc.

 

○ It adopts the PH-G0401 explosion-proof casing qualified by the country and adopts the structure of the casing heat dissipation method to bring higher safety to the system. The casing has explosion-proof and shockproof functions;

○ The equipment's power interface uses a military waterproof plug, and the power supply is pressed to open the switch with the indicator light displayed, which is convenient and practical

○ The image transmission front-end equipment can be fixed, portable and in-car use

○ The device uses a universal video interface, which can be connected to professional explosion-proof cameras, as well as ordinary analog cameras and digital video cameras (including helmet-mounted cameras)

○ The transmitter is mainly used for real-time video and sound signal transmission by ground personnel in flammable and explosive places, and can also be used for live transmission on ships sailing on the surface

○ Built-in rechargeable lithium battery at the front of the device, can work independently for 6 hours when the battery is fully charged

○ Non-explosion-proof occasions can be powered by a special adapter

○ Non-explosion-proof occasions can be powered by a special adapter

○ The transmitter uses encryption technology, which can prevent others from receiving the same frequency signal

 

○ Working frequency is adjustable, that is, it can be set within the specified frequency range

○ 6/7 / 8MHz, 1.5 / 2/4 MHz, multiple bandwidth output settings

○ Adopting COFDM modulation technology and H.264 image compression technology to ensure stable signal transmission and high-quality audio and video signals

○ Video input PAL / NTSC optional (factory default is PAL system)

○ You can input component video signals and 2 audio (left and right channels) signals simultaneously
