Sizheng - Home remote audio and video monitoring program software
Modern remote monitoring systems are based on mobile phones. The mobile video surveillance and alarm system is a set of intelligent systems that can be used in security applications. It can use the mobile phone to learn about the situation at home whenever you are in the network.
The remote system includes hardware and operating system in two parts:
hardware
Hardware devices include surveillance cameras, surveillance pickups, routers, storage systems (computers, set-top boxes, etc.) and display devices (computers, mobile phones, etc.).
installation
A camera (must have an audio input port) and a pickup are installed in the required monitoring area (home) to capture live pictures and sounds. Connect the camera to the storage device. The storage device must have monitoring software (collector) installed. And through the router to transfer audio and video to cloud storage.
Through the Internet, remote display devices such as mobile phones and mobile computers (viewing software monitoring terminals are required) can monitor the actual situation at home through the cloud.
The circuit diagram is as follows:
software
There are many free monitoring software on the Internet. Its software function basically meets the family's monitoring situation.
Acquisition side: Install the acquisition end on a storage device (computer, smartphone, tablet, or Android smart device). A surveillance camera with a pickup on the device link. Open the monitoring acquisition software to identify the camera set up the storage path (usually free monitoring software does not have cloud storage capabilities, it can only be stored to the local) and login account password and other information.
Viewer: Install the viewer software on the display device (mobile phone, computer, tablet, etc.). Open software to enter login information. You can monitor your home situation.
Product selection
Camera: Generally speaking, we want users to choose a camera with audio input function. Because in spite of the audio input port on the storage device, in order to better manage the audio and video (in the case of multi-channel audio and video), the corresponding sound from the screen can make the monitoring more realistic.
Pickup: Why pick a pickup? Some people choose a camera with a microphone for cost savings. However, the audio of these cameras often does not work well because the pickups built into the camera are passive microphones. The sensitivity of this microphone is quite low, and it is inevitable that there will be more noise during the recording when it is built into the camera. The advantage of the external pickup is that the highly sensitive monitoring pickup can omnidirectionally collect the sound of the monitoring area. The Sizheng monitoring microphone not only has a high fidelity effect, but also can effectively reduce the low noise. In general, the pickups selected for home monitoring are high-fidelity pickups (Sheng-COTT-C7 high-fidelity pickups, COTT-S2 high-sensitivity pickups).
Storage devices: We recommend using Android smart boxes on the premise that we already have a network (with a router). This kind of equipment is simple and inexpensive to install for monitoring only to meet the needs. Be sure to select a device with an audio input port when purchasing. In the case that there is no routing yet, it is recommended to use smart routing to save the installation process.
Surveillance equipment: There are no viewing devices at the moment. You can use the Android phone IOS phone that has been eliminated as a display device.

Stainless Steel Cut Wire Shot As Conditioned
Cut Wire Shot is a very important and popular Metal Abrasive.It is often utilized in shot peening processes when ferrous contamination of work piece is forbidden. As the most cost-effective one, the stainlesss steel cut wire shot, also named Stainless Steel Shot, is widely used for shot peening processes on stainless steel or inconel parts. When Blasting stainless work pieces or other metals need to be down as a pristine surface, stainless cut wire may be a very good metal abrasive to take into consideration. Stainless Steel Cut Wire shot as conditioned is usually used for shot peening processes on stainless steel or inconel parts. As for Longlived stainless steel cut wire shot, the minimum diameter could be 0.15mm and maximum diameter is 3mm. If you want, it could be bigger as your demand.
Concerning stainless steel cut wire shot, it has a very bright surface, maintains its shape longer then cast abrasives and it has a dust free surface. Stainless Steel Cut Wire is available as cut or conditioned and with various chemical compositions.The bulk density of stainless steel cut wire shot is very high and must be taken into consideration in relation to its use in equipment. Suitable equipment must be selected to convey stainless steel shot.
Generally, stainless steel cut wire shot could be classfied into two kinds. One is Stainless Steel Cut Wire Shot AS Cut and as conditioned. And then, stainless steel cut wire shot as conditioned could also be divided into three small groups according to their different roundness and they are G1, g2, G3.
