Surveillance System Recording Some time to skip what happened when playing back the footage

Hello, there are several cases of time skipping during surveillance video playback.

1. The power supply of the camera is not normal, sometimes the power supply is insufficient, there is no image, and the video recorder will skip the time when there is no image.

2. The signal line connection is not smooth, because the distance of the signal line is too far or the copper content is low, the signal is attenuated to a certain extent, the image is stuck or comes and goes, the video is not successful when the signal is very weak, and the time period will be skipped during playback, 3. The camera is faulty, sometimes good and sometimes bad, and the video recording is unsuccessful when the camera fails, resulting in skipping that time period during playback.

4. This situation will also occur when the power line or signal line is in poor contact.

5. This situation will also occur if the hard disk fails and the hard disk has bad sectors.

6. The equipment of the monitoring system has stopped working due to power failure, and the video recorder will skip when playing back at this time.

Solution: 1. Eliminate line faults, check whether the power supply is normal, whether the joints are connected, and reconnect the faulty places.

2. How much copper content is in the signal line, whether it exceeds the maximum cable distance, and the national standard super five oxygen-free copper for network cameras.

Adding a switch in the middle within 150 meters will not attenuate, and it is recommended to use optical fiber beyond this distance.

3. Check whether the camera is normal, if the camera is a problem, replace or repair the camera.

4. Check whether the hard disk is faulty, and replace the hard disk if there are bad sectors.

The above is the common problem and solution of the jump time of the surveillance video playback, if the problem cannot be solved, it is recommended to ask a professional monitoring engineer to check and repair. Hope.

Generally, no one moves this thing, and you look closely, and you will find that in fact, there is a 5 seconds missing in the middle, and this is the problem of setting, and the machine recording has time, and a file will be formed at a certain time, and this is called (packaging) There must be a time difference between the package, so it is generally 5 seconds (5 seconds to start recording), and the machine has settings, and you will find that it seems to be stuck in the middle, and it seems that there is something missing, in fact, you look at the time carefully, generally speaking, it should be coherent, and you are looking at the error of your eyes, and it is useless to look at the time carefully As soon as the screen switches, it feels like something is missing.

Pay attention to the length of the skip. And the number of times. It's possible that the video is segmented in the settings!

Also, does your company have remote monitoring? If there is, then when someone is monitoring remotely through the network, the time period will not be recorded! You can ask the installation company about this situation!

There are two possibilities, one is artificial editing, and the second is that someone closes or cuts off at a critical moment.

That time monitoring was turned off.

Maybe the original file was deleted.

Summary. Generally, due to the poor quality of the network cable, the crystal head is not good, and the maximum capacity of the switch exceeds the upper limit, etc., there is packet loss in data transmission. Let me give you a brief introduction.

If the monitoring screen is completely stuck, it is most likely caused by backbone line problems or poor performance of the core switch.

If all the monitoring pictures are stuck, it is likely that the backbone line, the line between the recorder and the switch is faulty, the network cable crystal head, the quality is too poor, you can consider replacing an original network cable test. In the monitoring system network, a large number of data streams need to be transmitted, which requires the switch to have the ability to stabilize data. The greater the number of cameras connected to a switch, the larger the amount of data flowing through the switch.

What is the reason for the intermittent phenomenon of surveillance video playback?

Generally, due to the poor quality of the network cable, the crystal head is not good, and the maximum capacity of the switch exceeds the upper limit, etc., there is packet loss in data transmission. Let me give you a brief introduction. If all the monitoring screens are stuck, it is very likely that the backbone line is caused by the backbone line problem or the poor performance of the core switch If all the monitoring pictures are stuck, it is likely to be the backbone line, the line failure between the video recorder and the switch, and the poor quality of the network cable, you can consider replacing an original network cable for testing.

In the monitoring system socks network, Jingjian needs to transmit a large number of data streams, which requires the switch to have the ability to stabilize data. The greater the number of cameras connected to a switch, the larger the amount of data flowing through the switch.

Not all of them, but occasionally, with a break of forty minutes.

That's not a network outage.

Under normal circumstances, it can be continuous**, but if you take fast forward, fast rewind** there will be intermittent phenomenon, in addition, there are also video recorders that use frame video, and the video recording is not continuous, frame by frame video, of course, ** will not be continuous, this kind of video mainly takes into account the relatively small file saved, which can increase the time to save the video.

Summary. How to see when someone passes by 1. Open the monitoring system that has been installed on the computer, and enter the "username" and "password". 2. After entering the system, click "Video Playback" in the bottom row.

3. Enter the "Video Playback" page, see that there are four squares on the right, click any square on the right first, and the box will turn into a green box after selection. 4. Click "Equipment", "Date" and "Time" in turn, and then click "Query", and the time period to be retrieved will be displayed in the query box. Double-click on any time period, and the screen on the right will display the screen you want to retrieve.

After entering the system, click on the "video playback" in the bottom row. 3. Enter the "Video Playback" page, see that there are only four squares on the right, click any square on the right first, and the grid will turn into a green box after selection.

4. Click "Equipment", "Date" and "Time" in turn, and then click "Query", and the time period to be retrieved will be displayed in the query box. Double-click on any time period, and the screen on the right will display the screen you want to retrieve. 5. After entering the video playback page, at the bottom of the screen, there are **, pause, cavity opening fast playback, slow play and other options, which can be selected according to your needs.

The DVR can view the previous recordings at any time, but it should not have this function to check when the playback has been performed.

It is recommended to turn on the motion detection function, and start recording when there is an object moving, so that you can save hard disks, and you can record for a long time.

The surveillance shows that all the recordings are successful, but what is the reason for skipping directly in the middle of the playback?

Hello, hello, there are several situations where there is time skipping during surveillance video playback1, the camera power supply is not normal, sometimes there is insufficient power supply, there is no image, the video recorder will skip the time without image. 2. The signal line connection is not smooth, because the distance of the signal line is too far away or the copper content is very low, the signal is attenuated to a certain extent, the image is stuck or the upgrade is sometimes and now, the video is not successful when the signal is very weak, and the time period will be skipped during playback, 3. The camera is faulty, sometimes good and sometimes bad, and the video recording is unsuccessful when the camera fails, resulting in skipping the time period during playback 4. 5. If the hard disk fails, the hard disk has a bad sector, and this situation will also occur 6. The equipment of the monitoring system has stopped working due to a power failure, and the video recorder will skip at this time of playback.
