Product Description   The product that you are viewing is the Non-stop working  Cell Phone Jammer with Waterproof design, which is developed specially for prisons and other large, sensitive facilities, such as military installations and government compounds. And as applying high technology this jamming system can be controlled remotely with activation and deactivation of the system is carried out only by using a Wireless Waterproof Software Controlled Cell Phone Jammer.   And apart from the above characteristic, this jammer device is constructed inside a special metal enclosure, incorporating an efficient "smart active" cooling system with incoming air filters, which enables the system to operate 24 hours a day and 7 days a week continuously even in hot weather. And the secure design ensures that the prison inmates and unauthorized prison personnel cannot tamper with the safe and continuous operation of the system.   If you are looking for one just come here and pick up one. We will of course offer you the high quality jammer at the best price.Features:High powerWaterproof designWith a extreme hard metal enclosureShielding range can be regulated by the computer remotelyAlarming system design in case of equipment abnormal problem and people’s sabotage, showed as below:The computer makes an alarming sound and e-mail notification to the administratora) RF line is artificially cutb) Equipment doors exception openc) Modules damaged.Easy outdoor installation and remote controlled operationAny computer with COM port can be available for the program software.It can be controlled in real time including RF output power and separate module as well as all the jammer’s working status.Specially designed shockproof ,Waterproof and RF shielded internal metal enclosureSmart active cooling system enables unlimited continuous operation in very hot temperatures with fans design.Module design based on high power RF amplifiers with VSWR and temperature self-protection technology.At a Glance:Each unit can jam up to five frequency bands simultaneously.Continuous operation, even in hot climates, with no time limit.Secure design to avoid sabotage.(VSWR) circuit protection to ensure system will not burn out should there be antenna short circuiting or disconnectionAntenna type options, directional or omni antennas option.Controlled via a computer,E-mail system.Turn on/off the jammer via computerAdjust the output power via computer.Turn on/off the jammer module separately.Special additional housing for all weather protection.UPS and battery backup in case of mains power failureApplication:Prisons and other large sensitive locations such as military orgovernmental compounds. It can also use in Oil and GasStorage Facilities and fields, Security Services, Military Units,Secret Services, Museums, Border Patrol and Drug Enforcement,Customs, etc.Product Notes:   The shielding range of the device will be determined by the local signal strength. In different situation, it will be with different performance.   Please try to put the device in a higher position while it is working. Itwill be better. The suggested height is about 8M.  To avoid the loss of function of the device, please try to avoid the device placed on or the metal materials.    Do not turn on the power before the antennas is installed, If the antenna is not properly installed in accordance with the manuals, the shielding range will be not so good. Make sure the correct installation before turn on the power.Specification:-CDMA800  850-894MHz-GSM900  925-960MHz-DCS1800  1805-1880MHz-PCS1900 1930-1990MHz-3G: 2110-2170MHzTotal Power: 250WFrequency Bands:Up to five bandsPower Supply:AC220V/ 110V    DC27-28VPower Consumption: 1000WShielding Radius: 200-500M (Based on back ground signal strengthNet Weight:42KGSize:72*45*32cmAccessories:Omni directional antennaPower supply cableCase key,RF cables
