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.

How to Choose High-quality Ip Cctv Tester 1

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.

Theory of Cable Fault Locator

The basic function of cable fault locator is in the power industry and some industries using cables, especially in some complex power systems. It is very difficult to find the fault of underground cable lines. However, in this regard, the continuous emergence of equipment with various functions and simple operation can not only reduce the high cost of fault detection, but also reduce the inevitable long-time power failure when difficult to find (cable fault locator) cable fault, which brings a lot of convenience to troubleshooting. Direct buried cable fault detection in underground direct buried cable and underground residential power distribution (URD) system is a very time-consuming thing, and will cause very inconvenient power failure to users. Some technologies may also damage the cable. For some equipment with high technical requirements, its operation is more complex, and only operators with strict training can use it, which brings a lot of inconvenience to the popularization and application of this kind of technical equipment. Therefore, the selection of appropriate technology depends partly on the knowledge of cable system design understood by the designer of fault detector, and also partly on the professional and technical knowledge of equipment and operators in this regard. With appropriate equipment and professional technology working on site, it is the first step to detect faults quickly and effectively. Hammering (pulse) method many power companies use hammering (pulse) method. This technique is effective in detecting high resistance faults in a simple (cable fault locator) cable system. The hammering method includes using a pulse or impulse voltage to impact the power cut cable. When an effective high voltage pulse strikes the fault area, the fault point flashover and produces a hammering sound that can be heard by the operator along the cable surface. However, detecting cable faults often requires several hammers, and repeated shocks may damage the cable.

Working Principle of Cable Fault Locator

The cable fault locator consists of three main parts: power cable fault tester host, cable fault locator and cable path tester. The host of the cable fault tester is used to measure the nature and total length of the cable fault and the approximate position between the cable fault point and the test end. The cable fault locator determines the exact location of the cable fault point based on the approximate location of the cable fault point determined by the host of the cable fault tester. For buried cables with unknown direction, a pathfinder shall be used to determine the underground direction of the cable. The basic method of power cable fault test is to apply high-voltage pulse to the fault power cable to produce breakdown at the cable fault point. When the cable fault breakdown point discharges, it generates electromagnetic wave and sound at the same time. It is very time-consuming to detect faults in underground directly buried cables and underground residential power distribution (URD) systems, and it will cause very inconvenient power failure to users. Some technologies may also damage cables. For some equipment with high technical requirements, its operation is more complex, and only operators with strict training can use it, which brings a lot of inconvenience to the popularization and application of this kind of technical equipment. Therefore, the selection of appropriate technology depends partly on the knowledge of cable system design understood by the designer of fault detector, and also partly on the professional and technical knowledge of equipment and operators in this regard.

Functional Characteristics of Live Cable Identification Instrument

Live cable identification instrument is of great significance in cable construction and maintenance. The charged cable identification instrument uses single chip microcomputer technology to encode the transmitted signal at the transmitting end, drives the large-diameter caliper to transmit the large current phase coded signal with an average value of 0. The single chip microcomputer in the receiver decodes and identifies the received phase coded signal. According to the uniqueness of the signal phase characteristics on the target cable, the target cable is identified from a large bundle of other cables. The live cable identification instrument can also directly connect the output signal to the cable in power failure operation. At this time, the grounding circuit can be identified to be more than 1000 ohms. It is a light, compact and portable instrument. It is suitable for various types of high and low voltage power cables. The instrument is composed of current pulse transmitter, receiver, transceiver caliper and several connecting wires. It has high-power current pulse output; The on-site received signal has clear characteristics, easy to carry, light and flexible, high sensitivity, can effectively suppress the on-site power frequency interference, and judge accurately and quickly; The protection circuit is reliable and not afraid of output short circuit; Large jaw Ñ„ 150 power cables suitable for various cross-sectional areas; There is a high-power isolation transformer inside, and there is no direct electrical contact between the operator and the mains.

Basic Principle of Live Cable Identification Instrument

As the running live cable is not allowed to damage any grounding wire and other connecting wires, nor is it allowed to directly add the output signal of the live cable identifier transmitter to the cable phase line with high voltage. Two difficult problems need to be solved for live cable identification. One is how to couple the cable identification signal to the cable; Second, the coupled signal is generally small, and the operating cable may have 50Hz power frequency electromagnetic interference composed of 50Hz unbalanced current, induced 50Hz interference current, cable distributed capacitance current, etc. the high-sensitivity receiving caliper has the problem of how to resist 50Hz power frequency interference. The charged cable identification instrument developed by US adopts single chip microcomputer coding and decoding technology and PSK technology widely used in the field of communication. The phase coded signal with an average value of 0 is transmitted on the transmitting caliper, and the single chip microcomputer in the receiving caliper performs phase identification after filtering the received signal by hardware and software. When the receiving caliper cards the cable according to the current direction, the identified cable ammeter deviates to the right, accompanied by audible and visual indication. The current direction of other cables is opposite to that of the identified cable, and the ammeter pointer deviates to the left. No audible and visual indication. This reflects the uniqueness of the identified target cable. It is easy to distinguish the identified cable from multiple cables. In addition, since the signal current strength on the identified cable is the same throughout the line, the electromagnetic signal strength received by the receiving caliper along the cable is the same. In principle, the identified cable is not limited by the length of the identified cable.
