Many people who are doing weak current projects will hear the word engineering treasure. Some people do not know what they are doing. Let's find out here. Engineering Bao full name is called multi-functional monitoring video tester, also called monitoring engineering treasure, it is a multi-functional monitoring project debugging tool that integrates video security monitoring and control project debugging and fault detection.
Security Tools What You Can't Face Start with Engineering Po!
Engineering Po incorporates features such as camera image detection, PTZ pan and tilt control, network cable testing, audio testing, and control protocol analysis. With an engineering treasure, engineers can usually complete the positioning, detection, search for faults, and find out the cause of the fault. Greatly improve work efficiency.
In the early days when monitoring engineering treasures did not come out, monitoring project debugging was a troublesome task. After all the monitoring equipment lines were installed, they looked directly at the monitor in the surveillance room. Which picture was wrong or wrong and then shouted under the camera with the intercom. The staff then climbs up and adjusts the ladder. Since the monitor image is different from the actual camera, the shift to the left shifts to the right. The propaganda is also smart. Just say, “move to the left of the camera, to the right of the camera. shift".
In security surveillance projects, the use of fiber-optic communications to solve the video surveillance transmission channel has become more and more common, engineering treasure can test the optical transmission channel in the security system, video and PTZ control, and high-precision digital multimeter to measure the strong part of electricity. The front-end monitoring equipment can be more fully maintained and installed. Engineering Po is a multi-function integrated portable tester, which is suitable for monitoring the installation, maintenance, and equipment maintenance of the engineering company. Professional appearance design; touch-type keys, better hand feeling; gold-immersed technology, keys are more sensitive and durable.

The main function of engineering treasure
1. High-precision optical fiber communication optical power measurement
Engineering Po integrated optical power meter adopts the most advanced hand-held instrument dedicated integrated chip for ultra low power operation. 3.5-inch TFT-LCD display for large-screen high-definition display. The operation is simple and convenient. Wavelengths 850nm, 1300nm, 1310nm, 1490nm, 1550nm Five wavelength correction points. Optical power can be displayed linearly or non-linearly, both for direct measurement of optical power and for relative measurement of optical fiber link losses. It is an essential instrument for the construction and maintenance of optical fiber communications, cable television systems, and security systems.
2, high-precision full-featured digital multimeter
Engineering Po built-in stable, high reliability 3/4 bit (6600 count) digital multimeter, clear readings, can be used to measure DC voltage, AC voltage, DC current, AC current, resistance measurement, continuity test, diode measurement, Capacitance measurement, automatic/manual range conversion, differential measurement and locking, complete functions, high measurement accuracy, easy to use.
Engineering Po built-in professional digital multimeter is suitable for engineering personnel to test the weak and strong electricity in the security system, as well as maintenance personnel to measure equipment maintenance and so on.
3, the screen shows the camera image
Engineering Po video surveillance tester adopts a large-screen digital LCD monitor. The display area is wider and clearer, and the camera image effect is displayed more intuitively and conveniently. The camera image can be displayed when the surveillance camera can be debugged.
LCD monitor brightness, contrast, color saturation adjustable, backlight brightness adjustable for field construction and maintenance.
4, video signal strength measurement
Engineering Po video monitoring tester has added video signal strength measurement to test whether the video signal is attenuated or excessively high. The video signal will cause signal attenuation because the video cable is too long. The attenuation of the video signal will cause the image to be dim and reduce the dynamic range of the image; if the video signal is too strong, it will cause a virtual image and reduce the clarity of the image. Engineering Po video signal measurement function, real-time display of the video signal level value, if the range is exceeded, the instrument's screen will have a prompt message display.
5, multi-standard image generator sends color bar to detect monitoring transmission channel
Engineering Po can send a variety of formats (PAL, NTSC) color graphic strips through the video OUT port. The graphic strips include eight colors: white, yellow, cyan, green, pink, red, blue, and black, through the monitoring center. Whether the monitor receives a color pattern bar to judge whether the video channel is normally transmitted, at the same time, through the color pattern bar received by the monitoring center, it can be judged whether the color deviation occurs due to transmission attenuation or interference. The device can also be sent by the video OUT port color pattern, while receiving and displaying at the IN port, suitable for on-the-spot detection of video transmission, such as video transmitter, video cable and so on.
6,12V power output, power the camera
Engineering Po video surveillance tester designed 12V 1A power output port specifically for the power supply of the camera, to provide temporary power for the camera. It is mainly used for live demonstration and testing of some cameras. At the same time, for some venues where cameras need to be installed, because the site has no power before the project is implemented, temporary power must be found to supply power to the cameras. The power supply output of the engineering treasure has played a necessary role.
7, audio test function, test the sound of the front-end audio device is normal
Engineering Po video monitoring tester's audio test function can test audio equipment such as pickups on the front end of video surveillance.
8, ball machine or decoder PTZ control
Engineering Po video monitoring tester includes Pelco-D/P, SAMSUNG, Panasonic and more than 20 kinds of PTZ control protocols. Through its own RS485 or RS232 interface, users can control the top, bottom, left, and right rotation of the PTZ, and Adjust the zoom, focus, and aperture of the all-in-one.
9. Preset position setting, call and setting of dome parameters
Engineering Po video monitoring tester supports PTZ presetting and recalling functions. The dome camera can save the position parameters such as the horizontal angle, tilt angle and camera lens focal length of the head under the current status to the instrument, and can also quickly call up the instrument. Prepositions.
Engineering Po video monitoring tester can call the main menu of the dome ball through the preset position and edit the parameters of the dome camera.
10, RS485 address scanning function to help engineers find the address of fastball
Engineering Po video surveillance tester's unique address scanning function can help engineers quickly find the address of the fastball. The maintenance project may not know the address of the fastball for some fastballs that need to be maintained. If the fastball is to be removed for inspection, the workload is large. Engineering Po independent scanning function can help engineers find the address of the dome camera.
11, UTP network cable test
Engineering Po's unique network cable test function, through the UTP Cable Test test port on the meter, can test the connection of various network cables (any two or more lines), and even the RJ45 connection of video surveillance engineering can be fast. Accurately displayed. Simple, convenient and practical.
Engineering Po is also a line splitter for the wiring project. In addition to displaying the connection method of the UTP network cable, it also displays the network cable number. The engineer can accurately determine and mark the beginning and end positions of the cable, and thus quickly manage the complicated network cable stack. Shun cable connection.
12, data capture function
The instrument can capture the control protocol code sent by the keyboard or DVR through the RS485/RS232 interface to check whether the PTZ control command data sent from the monitoring center can be received normally and verify the RS485/RS232 data transmission.
