This product can be used in conjunction with a variety of cameras .Its function is real-time synchronization of wireless transmission of images and sound , microwave analog signal ,There is no delay , the transmitter and the sound image of what is , and the receiving side image of what sound is entirely the same time .Open to the measured distance of 1200 m. Elevator shaft wireless monitoring transmission easy !

Installed by the factory testing and long-term customer experience reflects many years of accumulation, the product to be used in elevator shaft power better than other similar products effect , clear images without interference !

Individual customers interference occurs due to improper use , the image of flowers, is due no fixed transmitter and wall transmission ! Repeatedly remind customers not partition transfer , under the straight-line distance to a barrier-free environment in the transmission . In addition , the installation channels 1 and 4 may be the same or reversed under 2 and 4 under the same dial to reach completely prevent other signal interference.

Case 1:Lift a move will have interference. Image is flowers, stopped on the right, mind you buy a high amount of some higher power and communications , I put the well from the second floor elevator to the sixth floor, only 4 floors , but the effect well, it is a move to spend elevator after and sellers to communicate , tried many methods will not work . changing the 75-5 line will not workCase of communication with the customer is the customer tried many methods , but there is no way the transmitter on the car fixed, so a move to interfere with the elevator ! Put a lot of direction as well. Therefore, when using the transmitter must be fixed !

Case 2:When used, good penetration , less than 10 meters across the two walls no signal.If not , then the partition wall can reach 1000 m . Equivalent to sunlight , like a wall blocking is wearing is not the past . Therefore, the product must not partition transmission ! If you must partition purchase 1.2G products.
