Product Description Introduction:The mini transmitter is highly integrated digital video transmission equipment that can realize wireless video transmission in mobile and NLOS (Non line-of-sight) conditions. With professional clothes and pinhole camera, it can be used in public security bureau or security department to finish covert missions (technical investigation and covert intelligence gathering). It can be also applied in emergency and evacuation, railway, marine and so on. We can use the mini transmitter with a specially designed multifunctional amplifier to meet the requirement of longer transmission rangeProduct Application:The product is an ideal solution in remote surveillance, designed specially for the covert intelligence gathering market. By using a pinhole camera, the first responder can catch live scenes at the accident ground. Then the mini transmitter sends real-time images to the receiving center.MV2025TWSE Covert Mobile Video TransmitterFunctions & Features:Super low latencyWorking frequency and RF bandwidth self-adapted within specified rangeRS232 data unidirectional transmissionLow power consumption, small size and portable usage Separately workable and also compatible with external power amplifierSpy vest and pin-hole camera compatible High-strength aluminum alloy caseArmed force aviation plug for A/V and power interfaces; different pins for different function interface to avoid misplugRemovable lithium battery, easy operation and battery replacement Specifications:Power SupplyPower supply interfaceStandard interfacePower supply Combined transmitter: DC14.8V Mini video transmitter: DC7.8VVideo TransmissionFrequency output range300MHz~1.2GHz or user customizedRF bandwidth MHz6/7/8MHz or 1.25/2.5MHzPower output200mWC/N≥28dB@23dBmSHG>52dBcModulation COFDMVideo encoding MPEG-2/MPEG-4Encryption AES/ALLTECH Basic scramblingConstellation QPSK/16QAM @ 1.25/2.5MHzQPSK/16QAM/64QAM @ 6/7/8MHzFEC1/3, 2/3 @ 1.25/2.5MHz1/2, 2/3, 3/4, 5/6, 7/8 @ 6/7/8MHzCarrier 2KGUI1/8, 1/16 @ 1.25/2.5MHz1/4, 1/8, 1/16, 1/32 @ 6/7/8MHzVideo input level1~1.2Vp-p@75ΩVideo input format PAL/NTSCVideo resolution 720x576(PAL) 720x480(NTSC)Video amplitude-frequency characteristic dB0~4.8MHz-0.5~1.55.5MHz-4.0~1.5Audio input Left/right channel, stereoRS232 control interfaceStandard RS232 level, 9600, 8, N, 1RS232 data interface Standard RS232 level, support 1200~115200Delay Less than 60ms Environment Working temperature-25°C~55°C Storage temperature -40°C~70°C Ambient humidity No less than 95% Protect standard Rust protection and shakeproof Appearance Dimension 101mm ×81mm ×15mm Weight 0.28Kg (include battery) RF interface Standard SMA MV2025RH7-JKYZ Portable Suitcase Video ReceiverFunctions & Features:MPEG-2/MP@ML/4:2:0 DVD decoding standard Receiver internal parameters configurableAuto front error correction Frequency continuously adjustablePower off memory Standard definition image and hi-fi stereo outputFeed short-circuit protect and indicationLithium battery power supply with power displayAVI format video recoding; USB flash disk video recordingH.264 video compression with Ethernet transmissionFull-featured PTZ camera remote control COFDM demodulation and high receiving sensivitity (single antenna -92dBm, diversity receiving -96dBm)Specifications:Power SupplyWorking voltage VAC220V±20V, DC14V~DC16VWorking current A≤2.5A@ DC15.5V Video Receiving Frequency input range170MHz~860MHzRF bandwidth1.25/2.5MHz or 6/7/8MHzReceiving sensitivity-96dBm~-20dBm@8M/-106dBm~-20dBm@1.25MDemodulation COFDMVideo decoding standard MPEG-2/MPEG-4Constellation QPSK/16QAM @ 1.25/2.5MHz; QPSK/16QAM/64QAM @ 6/7/8MHzFEC1/3,2/3 @ 1.25/2.5MHz,1/2, 2/3, 3/4, 5/6, 7/8 @ 6/7/8MHzCarrier 2KGUI1/8, 1/16 @ 1.25/2.5MHz; 1/4, 1/8, 1/16, 1/32 @ 6/7/8MHzVideo output level1~1.2Vp-p@75ΩVideo output formatPAL/NTSCVideo white bar amplitude mV650~720mVVideo synchronous amplitude mV260~275mVVideo amplitude-frequency characteristic dB0~4.8MHz-0.5~1.55.5MHz-4.0~1.5Rx feed output voltageDC10V~DC12VRx feed output current (MAX)800mAAudio outputLeft/right channel, stereoRS232 control interfaceStandard RS232 level, 9600, 8, N, 1RS232 data interfaceStandard RS232 level, support 1200~115200Command Command air baudrate600bps~19200bpsPower output≥32dBmKeyboard communication protocolPelco-P such multiple protocols with baudrate adjustableKeypress Rubber button, numeric keypad, camera function keysEnvironment Working temperature -25°C~55°CStorage temperature-40°C~70°CAppearance Dimension 460mm×370mm×180mmWeight 10.1kgBattery weight 1.1kgColor Black
