Why can monitoring only look at the replay of the day,

First of all, you need to determine the brand of your monitoring equipment, if there is a software manual, it is best to look at it first. Secondly, your problem description is not very clear, under what circumstances can you not respond to the date, you can only look at the day, this is not understood, the date can not be clicked and the monitoring of the day of playback should be two different things.

Before installing the monitoring, every time I played with my father, he always said, "Let's go, let's go", afraid that I would spend money. Now that the monitoring is installed, he doesn't urge me anymore, he chatters slowly every time, not in a hurry. Not only can I see their every move, but I can also chat with them, making up for the regret of not being able to get along with each other right now.

It's a lot closer, it's like we're living together. In the early morning of April 5, Zhao Ren's parents watched him drive away from home. Interviewee for **丨Beijing News.

Reporter Wu Linshu丨Proofreading by Hu Jie丨Liu Yue.

Outcome. There are 100 million people aged 60 and over living in rural China. According to the Rule of Law**.

According to relevant reports, the left-behind elderly in rural areas are accompanied by villages and land, and the burden of farming is heavy and the sense of loneliness is serious. In this context, more and more young people who are working abroad are installing monitoring equipment in their hometowns, so that they can check the status of the elderly at any time and communicate with them.

After Chen Xiaodong's mother died, his father became an empty nester and stayed in a village deep in the Yishan Mountains in Shandong. "My dad's loneliness at home alone, the loneliness that I never saw him directly before, just by imagination. Chen Xiaodong felt that after installing the surveillance, the loneliness of the old man seemed to overflow the screen and poured towards him.

Zhao Ren's parents stayed in Liaodong.

A small mountain village has been more than 20 years, and during this year's Qingming holiday, he installed three surveillance cameras at home, one to prevent theft, and the other to check the condition of his elderly parents at any time, and supervise his mother to measure blood pressure and take medicine. Not long ago, Zhao Ren's monitoring on a certain platform became popular all of a sudden.

In the picture, the septuagenarian mother thought that the camera was spent, worried that her son would not be able to see clearly, stepped on the cabinet, grinned and wiped it with a towel. "My parents are old and so far away, so if I leave one more image, I will leave a little more thoughts, and when they are 'a hundred years later', they can look at it from time to time. Zhao Ren told the Beijing News reporter.

The Beijing News reporter interviewed the above two "wanderers" who monitored security in their rural hometowns and listened to their stories about security monitoring.

Under normal circumstances, community monitoring can last for about 7 days, casinos for about 15 days, finance-related venues for about 26 days, and in the case of banks, about 3 months to half a year. The storage time of the surveillance video and the hardware memory of the host, the method of recording, and the number of frames of the recording.

It is closely related, so the specific time should be subject to the actual situation.

Expand your knowledge. The monitoring system is one of the most widely used systems in the security system, and now the more suitable construction site monitoring system on the market is the handheld communication equipment, and the monitoring is now the mainstream. From the earliest analog monitoring to the hot digital monitoring in previous years and then to the current ascendant network monitoring, earth-shaking changes have taken place.

Develop. First generation.

Traditional Analog Closed Circuit Surveillance System (CCTV):

Rely on specialized equipment such as cameras, cables, recorders, and monitors. For example, the camera outputs a ** signal via a dedicated coaxial cable. Cables are connected to dedicated analog devices such as splitters, routers, switchers, cassette recorders (VCRs), monitors, etc.

Analog CCTV has a number of limitations:

Heavy recording loads must be removed from the recorder or replaced with a new videotape, and the videotape is vulnerable to loss, theft, or inadvertent erasure.

The low quality of the video recording is the main limiting factor. The quality of the video decreases as the number of copies increases.

Second generation. Current "analog-digital" monitoring system (DVR):

Analog-digital" monitoring system is a digital hard disk recorder DVR as the core semi-analog-semi-digital scheme, from the camera to DVR still uses coaxial cable output signal, through DVR at the same time to support video recording and playback, and can support limited IP network access, due to DVR products, there is no standard, so this generation of system is a non-standard closed system, DVR system still has a large number of limitations.

Port. Instead of generating images in the form of continuous analog** signals, these cameras generate JPEG or MPEG4 data files that can be accessed, monitored, recorded, and printed by any authorized client from anywhere on the network. The all-IP** monitoring system is its huge advantage.

Simplicity All cameras are simply connected to the network via cost-effective wired or wireless Ethernet, enabling you to leverage your existing LAN infrastructure. You can use a Category 5 network cable or Wi-Fi.

Transmit camera output images as well as horizontal, vertical, zoom (PTZ) control commands (even directly via Ethernet).

Powerful central control An industry-standard server and a set of control and management applications can run the entire monitoring system.

Generally, the monitoring can be stored for more than a month, and this time can be replayed.

The monitoring and storage time is generally stipulated as follows: 7 days for the general community; 15 days for general entertainment venues; 26 days for the financial sector; Banks for 3 months to half a year. The length of time that surveillance footage is stored is generally related to the following points:

1. The hard disk capacity of the host: Under normal circumstances, a camera records continuously for 24 hours, and the required hard disk capacity (different systems have different parameters, the minimum is hours). 2. Video recording method:

As the name suggests, mobile recording is when there is a moving object through the monitoring range, the host starts to record, and the other time is not recorded; Continuous recording, on the other hand, is 24-hour uninterrupted recording. 3. The number of frames of the video! The system defaults to 25 frames.

This means that 25 shots** are recorded in one second.

Hope mine is helpful to you.

Only when the monitoring system uses computer video recording or hard disk video recorder recording, can the monitoring record and view the playback. If it is a computer connected to the monitoring, just open the monitoring software to find the [video] menu, the DVR can be directly on it**or by copying the video to the computer**. Here's a closer look:

1. First of all, make sure that there is a corresponding hard disk or computer in your monitoring system as the medium of recording before you can view the playback; To use the computer, you only need to open the monitoring software, select the [Recording] menu, you can enter the time and camera serial number to find the video file at that time;

2. If it is a host made of DVR, you can directly connect the display or back up the content through the computer**;

This has to look at the kind of monitoring, there is real-time monitoring, there is hard disk monitoring, the real-time kind is a return visit on the mobile phone, the kind of hard disk, you can view it directly.

Monitoring depends on whether there is a storage function, and if there is a storage function, it will be available in the main menu. Playback options.

Summary. There are many factors that go into keeping surveillance footage.

First, the size of the hard disk capacity in the DVR. The larger the capacity of the hard drive, the more storage.

Third, the number of cameras connected to the hard video recorder. The larger the number of cameras connected to the DVR, the shorter the recording and saving time is (assuming that a 1T hard disk is connected to 6 heads and can be recorded and stored for 14 days, then the same DVR can only be stored for 7 days when connected to 12 heads).

Fourth, the time period of recording. Some monitors only record during the day or only at night, so that the number of days saved is more, and if the 24-hour recording is relatively short.

Typical monitoring can be played back for several days.

Hello, I am a partner lawyer of the platform and have received your question.

It is generally thirty days.

The surveillance camera installed in 2019 can play back for a few days, 60006000

More than 6,000 yuan.

There are many factors that go into keeping surveillance footage. Let the size of the capacity of the hard disk in the DVR be buried. The larger the capacity of the hard drive, the more storage.

The larger the number of cameras connected to the DVR, the shorter the recording and saving time is (assuming that a 1T hard disk is connected to 6 heads and can be recorded and stored for 14 days, then the same DVR can only be stored for 7 days when connected to 12 heads). Fourth, the time period of recording. Some monitors only record during the day or only at night, and the number of days saved is more if you read the slippery sample, and if you record 24 hours a day, the time will be relatively shortened.

8 cameras.

It depends on the specific factors.

It cost more than 6,000 yuan.

In your case, it's usually seven days.

There is also a 10-camera installation in January 2019 that costs 12,000

Monitor how long it lasts.

Seven days.

Summary. Hello dear <>

The monitoring can only see the replay at that time, can the mobile phone see the replay of the previous two days?

OK. Generally speaking, surveillance cameras will have three days of free storage, of course, some may not, depending on the situation, but it is definitely possible to look back at the monitoring of the previous few days, but more than three days are required to pay for an additional opening, of course, you can also not choose cloud storage, you can use memory card local storage, you can also watch back.
