the first is their acquisition in a different way, video USES the real-time monitoring of surveillance cameras in parking lots, and image capture parking lots, and treatment and to assess the usage of parking space, at the same time also can identify the license plate number.Ultrasonic scheme using ultrasonic ranging principle, to emit ultrasonic parking Spaces, according to echo to determine whether there is vehicle parking Spaces.
second, their way of communication, video program USES a TCP/IP protocol, the transmission speed is fast, convenient wiring, expand the upgrade is very convenient.Ultrasonic scheme using CAN bus, stability is good, just RS484 general stability, transmission speed is generally.
third, they’re different system function.Video solutions have parking guidance and reverse at the same time find two big functions, and can monitor the video;And ultrasonic approach generally only parking guidance function, if you need to find car reverse function, independent of the brush card should be added to find the car system, vehicle positioning machine installation, next to the parking space users located in, get off to a credit card is not very convenient, and is independent of the two systems, the large number of devices need to install, construction wiring trival,
overall, video scheme adopts advanced video detection technology, high intelligent degree, find a car in reverse side effect is obvious, as long as the user query input on vehicle license plate number, the screen will display take the best route, car and because of using TCP/IP protocol, extended more, such as through a smartphone to connect to the yard WIFI, can query the location of the vehicle on the mobile phone and so on.And ultrasonic approach in contrast is not so advanced, but the plan cost is relatively low, if need to meet basic parking guidance, is a good choice.
