Do not underestimate this one up lap, without it, the lens and the camera can not focus properly, the image becomes blurred. So before installing the camera, first look at the camera and the lens is not the same kind of interface mode, if not, then you need to increase or decrease depending on the circumstances circle. Some cameras do not pick laps, but after using image adjustment ring (such as Panasonic products)

■Mobile and NLOS(Non line-of-sight) transmission
■High strength aluminium enclosure, dustproof,rs 458, waterproof and shockproof
■Lithium battery for power supply(continuous working time of every battery is an hour)
■Modular design and highly integrated
■Adjustable working frequency
■Can be used conveniently with the specially designed clothes
■Transmission security by encryption of AES 128 bit/ ALLTECH Basic Scrambling
■Matched with multifunction amplifier for longer range requirement. The transmission range can be up to 80km in LOS (line-of-sight) condition
Product 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.
COFDM video transmission
The COFDM mini transmitter is a new concept in remote surveillance, designed specially to meet the special requirements of covert missions. This product is modular design and highly integrates the antenna, digital modulation and AV compression into one. Every lithium battery can support the system to work for an hour continuously .If used with the multifunctional amplifier, longer transmission range can be up to 80kms in LOS (line-of-sight) environment.
