How to Choose High-quality  Ip Cctv Tester
How to Choose High-quality Ip Cctv Tester
If you are installing an analog surveillance camera system, you might want to consider taking a few handy cables with you. Later on this blog post, we will delve into the types of cables you will encounter when you start a hard-wired surveillance camera system. Let's start with Ethernet cables, the most common cables you need for your hard-wired surveillance camera system.For an analog HD / TVI surveillance camera system you need Siamese RG-59 cables. With these cables, you can power your surveillance camera and receive video information from the camera when only one cable is running. Use a Siamese replacement cable for your surveillance cameras, use it for your computer, use a Siamese replacement cable for your printer or use it when your network needs something different.By using PoE switches and injectors, IP cameras can supply and transmit video with a single cable, reducing cable costs compared to CCTV. CCTV uses coaxial cables, while IP cameras use the standard Cat 5E and Cat 6 network cables.IP cameras work by twisting a pair of coaxial cables for a wireless connection. One of the advantages of IP cameras is that they can be powered by a pair of twisted Ethernet cables, eliminating the need to lay electrical wires. IP cameras have an aVision capability of IP that surpasses analog systems.Analog cameras, for example, require a separate cable to control pan, tilt and zoom functions. They are also vulnerable to security breaches as the feed can be intercepted and the recording device stolen. IP cameras can accept power, video, audio and PTZ controls and control the signal via a single cable.The cabling you want to install depends on what you have in the surveillance camera system and what type of camera you want to choose. Mounting a surveillance camera on the outside of a house may seem like a daunting task, but it is the only way to get a camera to work the way it is designed. When viewing a PTZ camera, you want to monitor the live video feed over a large area and be able to zoom in and see more detail, especially in the case of a security guard overlooking a parking lot.There are two types of video surveillance systems: CCTV (closed circuit television, also known as analog) and IP (also known as network cameras ). IP cameras are digital cameras that send signals over a cable and are stored in a network. They are the biggest technological advance in cameras ever produced.CCV systems convert the video signal into a format that can be used for television (video recorders and DVRs). IP cameras convert video signals into IP packets which are transmitted to a storage device such as a server (NAS) or stored on board the camera over a data network (Internet network). High-quality HDCVI cameras (Solid Copper Coax Roll-off) can transmit video up to 1,600 ft.The recorded H.264 video file can't be played in Windows Media Player when it is played by the tester. The video stream is not displayed on the tester if the data rate is close to 0 KB / s. For this reason, the video file must be converted to MP4 format before it can be played in the test.Some private security cameras have optical zoom lenses (digital zoom) that trim and enlarge the camera while shooting. The more megapixels the camera sensor has, the more you can zoom in to see things better. The 1080p is the standard resolution of the cameras we tested and will benefit from a model with a higher resolution sensor.The warranty does not cover operating system errors caused by third-party apps. You can use the built-in Chrome or Firefox web browser to download the camera app and camera information. We recommend that you use an existing VLC to play the video clips.Our security camera testers are designed to facilitate the installation, maintenance and testing of security cameras. A shopper who bought a CCTV camera tester used it to test his camera before he started installing it in his home. A closed circuit TV tester is a handy tool for professional installers of CCTV security systems and do-it-yourselfers to set up and configure CCTV cameras from any source.CCTV testers feature a colour LCD screen, video port, rechargeable lithium batteries and several types of colour bars for signal output. The Cat6 cable is the most widely used cable in the world and Balun is widely used, but wearing analog video destroys clarity, so the passive Balun should be used according to the manufacturer's recommendations. For a fast and dirty workshop, check the analog camera and look at the test card to show clarity outside the camera.The Evertech screen is not the best, he writes, but it's fine given the cost. A reviewer looking for a CCTV tester IP camera and monitor kit is stating that it comes at an unbeatable price, considering he only needs it for a single home security setup.The Koolertron GH iPCT98, which is hard to beat even for $300, runs on Android and iOS apps, meaning that you can download and install a word processor or calculator program and reduces the number of devices a technician has to take to the field.The vast majority of private surveillance cameras now have mobile apps, and many are focused on how to do it remotely. Web portals offer more flexibility to access your videos and notifications. Another aspect of the functionality that should not be overlooked by a CCTV tester is the ability to work with analog IP cameras.Additional features vary from camera to camera, but our top picks offer enough variety to separate them from the rest of the competition. Remember that these cameras are designed to help you keep track of what is happening around your home.

What Should Be Considered When Purchasing a Cable Fault Tester
What Should Be Considered When Purchasing a Cable Fault Tester
Cable fault tester is a common cable fault detection equipment, and its accuracy and detection speed are guaranteed. We are used to evaluating this thing before we buy it, from its performance, value, price and other aspects. After that, we will decide whether to buy it. So, what evaluation should be done when purchasing a cable fault tester? When selecting the cable fault tester, the cable fault tester needs to understand its performance. Is its overall performance stable, or is it convenient in the whole operation? If there are problems in the operation and unstable performance of the cable fault tester you choose, it will certainly lead to more problems in the whole use, not to mention that the cable fault tester you choose is a test suitable for your own use, which can not highlight its whole use value. Therefore, when selecting the cable fault tester, we should pay attention to these two points: 1. How about the performance? Before choosing a cable fault tester, you'd better understand and test several different cable fault testers, that is, find some early tests to see if they really have high usability. 2. Quickly detect the fault point and find the problem of your own equipment in a very short time, If you can, it can show that it is a very good cable fault test. If you can't meet this standard, you will waste more time and money, and the selected cable fault tester will not be suitable for your own use. Therefore, we can understand how to select a more appropriate cable fault tester. After selecting an efficient and suitable cable fault tester, the next step is how to use it. What if you can better operate the cable fault tester to enable you to quickly detect the fault point? 1. Understand the instructions of the cable fault tester. After you get a cable fault tester, you need to understand its operating instructions before preparing for operation. Some people feel that they have a certain understanding of the cable, so it is not necessary to understand its operating instructions when using it. In fact, this is not the case, Most of the time, my knowledge is very different from professional operation, so I can understand the contents of the operation manual in advance before use, which naturally has a very good guarantee for the whole operation after use. 2. Check the circuit. When using the cable fault tester, do you need to test in advance or find out if there is a problem with its circuit connection? If there is a problem that needs troubleshooting, you also need to know whether the whole connection is normal in advance, so as to have higher detection efficiency in the whole detection, know the problem of cable fault, and find a good solution, so as to ensure the working performance of the whole power system. Generally speaking, after the carefully selected cable fault tester, the equipment performance of the cable fault tester is guaranteed. In the process of cable fault detection, the corresponding fault results can be obtained according to the fault performance in the operation manual.
Pulse Flashover Method for Fault Detection of High Voltage Cables
Pulse Flashover Method for Fault Detection of High Voltage Cables
Cable has a very important application scenario in our daily life. It can be said that we can't live without cable. In order to ensure the normal use of the cable, it is necessary to regularly detect and maintain the cable. In case of cable failure, the fault point shall be found out in time for maintenance. There are many cable fault maintenance methods. Today, I mainly introduce one of the high-voltage cable fault detection methods, pulse flashover method. For high resistance fault, due to the large resistance at the fault point, the reflection coefficient at this point is very small or almost equal to zero. When measured by low-voltage pulse method, the reflected pulse amplitude at the fault point is very small or there is no reflection, so the instrument can not distinguish it. There are two common high voltage flashover measurement methods, namely DC high voltage flashover measurement method (direct flashover method for short) and impulse high voltage flashover method (impulse flashover method for short). 1、 DC high voltage flashover method (referred to as direct flashover method) when the fault resistance is very high and a stable resistance channel has not been formed, the gradually increased DC voltage can be applied to the tested cable. After reaching a certain voltage value, the fault point is preferably broken down to form flashover. The flashover arc is used to form a short-circuit reflection on the added voltage, and the reflected echo is formed by a high resistance source at the input end to form an open circuit reflection. In this way, the voltage will be reflected many times between the input and the fault point until the energy is exhausted. 2、 Impulse high voltage flashover method (impulse flashover method for short) when the fault resistance is reduced and a stable resistance channel is formed, the DC high voltage cannot be added due to the limitation of equipment capacity. At this time, it is necessary to use impulse voltage test. The DC high voltage charges the cable through the ball gap until breakdown, and still generates short-circuit reflection with the flashover arc formed by it. The measuring inductance L shall be added at the cable input end to read the echo. The radio wave is reflected by short circuit at the fault point and l at the input end, and multiple reflections will be formed during this period. Due to the self induction phenomenon of inductance L, it begins to show open circuit reflection due to the current blocking effect of L, and shows short-circuit reflection after a certain time with the increase of current. The whole circuit consists of capacitor C and inductance L, which constitutes a large process of L-C discharge. Therefore, the wave process at the line input is a nearly attenuated cosine curve superimposed with fast pulse multiple reflection wave. 3、 High voltage cable fault detector is generally used. High voltage cable fault is high resistance fault, and high voltage flashover method is used to measure the distance of fault point. This method uses st-330b cable fault locator as experimental equipment. 1. Wiring mode: firstly, complete the wiring of high-voltage flashover as required; Then, connect the sampler with the ranging host with a double clamp test line, and then place the sampler next to the grounding wire of the high-voltage capacitor. 2. Equipment operation (1) start up, select the sampling method as flashover, the pulse width is the default, the cable type is the physical type, and the reading accuracy is the default. (2) Use the high-voltage equipment to discharge the cable, and then click the orange sampling button on the right to start sampling until the waveform is collected. Press the sampling key again to stop sampling. (3) Study the waveform, move the vernier ruler to the starting point and ending point of a waveform, read the waveform, and the distance of the fault point will be automatically measured in the upper left corner.

What Problems Will Be Encountered in the Use of Underground Pipeline Detector
What Problems Will Be Encountered in the Use of Underground Pipeline Detector
As a new type of intelligent stethoscope, underground pipeline detector is used to survey underground pipelines. It is composed of transmitter, receiver and accessories. It is mainly used for underground pipeline positioning, buried depth measurement and long-distance tracking, as well as pipeline insulation fault point measurement and search. The equipment adopts multi coil electromagnetic technology, which greatly improves its depth determination accuracy and target pipeline identification ability. It can accurately track and locate the target pipeline even in the area with dense and complex pipelines. However, due to the complexity and diversity of underground pipelines, a better method is to combine various technical methods for general survey. The common site conditions in the operation of underground pipeline detector are as follows: 1. Track from the joint or handover box. Before the cable applies the transmitter signal, the common connector on the cable needs to be removed to track the target pipe. If all cables are to be tracked from the junction box, the transmitter can work in an inductive manner, placed on one side of the junction box and in line with the cable to be tracked. 2. Long distance tracking cable. In order for the transmitter signal to transmit a sufficient distance, it is necessary to remove the grounding connection of the cable. When the joint or joint is grounded for safety or lightning protection, surge arrester (anti overload) can be used to replace the grounding of the joint or joint, so as to protect the cable and make uninterrupted positioning possible. 3. Is the connector spike. Most cable connectors or connectors will generate spike pulse when the receiver responds. Working experience and understanding the local situation will help the operator to judge whether the spike pulse indicates that there is a connector box. 4. It's a metal guardrail. The cable is usually buried directly under the road outside the road metal guardrail, and the signal is combined with the continuous metal guardrail. The metal guardrail is close to the antenna at the lower part of the receiver, which is difficult to track. When it comes to the receiver, this difficulty can be overcome by making the internal antenna at the lower end flat with the metal guardrail. 5. Street lighting. Generally, the metal column of street lamp and the metal shielding layer of lighting cable are connected with the metal column. At this time, the transmitter signal can be connected to the metal column of street lamp. If the cement lamp post - unless the lighting cable can be connected to the maintenance rack and grounded, the transmitter signal needs to be connected to the metal shielding of the lighting cable. Knowing the relevant location and depth of lighting cables (and other street facilities on the same lighting system) can help track lighting cables. A connection point may apply signals to a large area of cables. It is also feasible to use street lamp posts to apply signals to other power cables, but the signal may be weak because the signal may have been transmitted for a long distance before returning to the substation and can flow out of the system again. At this time, the transmitter can increase the output power mode and increase the output power. This method can locate cables that are difficult to apply signals or inconvenient. For cables coming down from wooden poles, cement poles or lighting columns, the transmitter can be placed in sensing mode to apply a signal by making a right angle to the ground on the pole.
