The reason for the delay in the CCTV image

As you know, in order to maintain security in today's world, it is necessary to use CCTV cameras. But sometimes these cameras may encounter problems that slow down their performance.

Here we have recommendations for you that if a problem occurs, first check your CCTV camera and if the problem is not solved, contact experts or support.

In the following, the reason that causes a delay in the performance of CCTV cameras will be discussed.

Please stay with us until the end.

If you don't want to do the wiring, wireless CCTV cameras are a great choice. Wired cameras can be difficult to set up and require you to unplug the system to perform repairs. Also, if you rent the property, wiring is probably not possible. Moreover, if you have to move your cameras to other places in the house, it can become a big challenge for you.

Imagine spending all day wiring cameras in the yard, only to accidentally pick the wrong angle. For this reason, many are turning to wireless security cameras. However, one of the big drawbacks of using wireless cameras is the heavy load they place on the network, especially if all the video is broadcast live 24/7. So what can you do about this problem?

It has been reported that there is a delay between motion detection and the start of video recording. In other words, when motion is detected, the camera starts recording video, but by the time the recording starts, there is enough time for the target to reach the camera or change its orientation. This issue seems to be related to the sensitivity of motion detection. People have also stated that even if they set the camera's motion sensitivity to maximum, this problem still occurs.

Modem limitations
Most of the time, Internet Service Providers (ISPs) or ISP-provided devices are not designed for non-routine home use. In fact, high-quality video transmission over the network is highly compressed, and many routers and firewalls limit their speed to a low speed. For modems, the Data Over Cable Service Interface Specification, or DOCSIS, is an international communications standard that adds high-bandwidth data transmission to cable television. If you only have a few cameras but intend to stream live, a DOCSIS 3.0 modem should be sufficient. But if you plan to expand the number of cameras, you should probably upgrade to version 3.1.

Checking your IP CCTV without delay: a quick guide

Video routing
Most routers are not built to stream high-quality video over the network at the same time as day-to-day Internet routing. You have several options here, but in general, the simpler solution to control streaming from cameras is to assign them a separate wireless bridge that connects to your main router. With this method, you can expand your number of cameras as much as you want and you will only need to add more bridges. One of the advantages of this method is its low cost. You can get a DD-WRT router for less than $10 and use it for all your cameras. But remember that the bigger the wireless camera network, the more complicated it will be.

If you don't want to change the router software, you can always get a wireless access point (Point of Entry). Just make sure to point it in the direction of your IP cameras.

Video compression and network video recorders
If you don't want to change your current network infrastructure, look into using higher quality video compression. This can reduce video quality, but should reduce the strain on your wireless network. It's a decent solution for everyday use, but if you plan to use your cameras for security purposes, it's recommended that you get the best video quality.

It's also likely that any lag you're experiencing is due to your hardware factors. If you have a network that needs to be able to handle video, or you're using a bridge, your hardware is probably having trouble processing and decoding video. A simpler solution is to install a Network Video Recorder (NVR) on your network. Similar to a cable DVR, this device allows you to store and play back videos. The NVR connects to your network, so connecting it to a bridge would also be useful.

Consider professional supervision
The purpose of video surveillance is to protect your home and family. If your cameras are not properly configured in the network, you will not be able to see possible events in urgent or dangerous situations.

From the operator's point of view, this delay is caused by the time between the camera and the display.

Between the camera and the display, a video signal passes through several stages, each of which can be a source of delay. To improve this delay, it is useful to understand the path traveled by the video.

Video recording is the first step in the camera. When a camera's lens and imager capture an image, they must encode it using a video codec to create a data stream (eg, MJPEG, MPEG-4, H.264). This coding is done inside the IP cameras or in the case of analog cameras, inside the video encoder. The performance of the encoding processor and the choice of video codec play an important role in the speed of this process. The slower the encoding processing, the greater the delay.

After encoding, the encrypted video is moved over the network. As with other network data, video data streams are broken up into smaller packets that travel through the network and are recombined at the destination. Packet routing is a means of determining network delay. Obviously, network design has an effect on the speed and efficiency of data transmission.

After all the video packets arrive at the destination, you need to combine them in the right order and somehow decode them so that they can be viewed on the monitor or display. This step takes place on the player. Like the encoding stage, the processing power of the device and the choice of codec also affect the efficiency of this process. An important point about decoding is that it is more difficult than encoding, and as cameras with larger data streams such as megapixel cameras cause more traffic on the network, decoding must also be prepared for heavier processing.

After decoding, the video streams are transferred to the display for viewing. Gradually, today's LCD monitors are used in video security control rooms. Although LCDs have many advantages over traditional CRT monitors, they also introduce some latency because decoded video must be processed before it can be displayed.

Finally, if a system operator uses a keyboard and joystick, this keyboard controller may introduce latency when sending its control signals over the network.

Fixing the delay problem of CCTV cameras
If the new computer has a weaker memory or processor for the graphics card, the video will seem to run slower because the camera feed will be processed more slowly. Sometimes you may notice that there is a delay between the live streaming of the video and the actual time. As with any live internet streaming service, expect a slight delay (perhaps a few seconds). If the lag is noticeably longer, try some solutions here:

If you have too many open programs running on your device, they can slow down the overall performance of the device. Close some apps, like the Nest app, and then just open the Nest app to view your video.

If the delay is longer than 10 seconds and occurs after a long time of viewing video in the Nest app, reload your device: Go to the Nest app home screen and tap to refresh your camera.

If your camera, phone, tablet, or computer is connected to a Wi-Fi extension, there may be additional latency, which creates additional relay time between each device and the camera. If you're using a Wi-Fi booster at home, connect your camera directly to the Wi-Fi router to reduce latency.

It is also possible that the delay in your camera video is caused by problems in the network on both sides, which we mentioned in the first part of this article.

If the camera doesn't connect easily, it's best to use the device's setup guides and instructions.

Try more detailed Wi-Fi suggestions:
All security cameras have a delay relative to real time, and the cost or quality of the camera does not greatly affect the severity of the delay. On the most expensive cameras we've tested, the delay can be anywhere from 5 to 10 seconds, or even longer. We've noticed that we can start recording, then go back to our computer and see ourselves on the screen.

Latency, especially when coupled with motion detection, can be problematic. Many cameras correctly send motion detection alerts, but the images they send or record often don't produce what they're detecting.

Next, we talk about more problems and other CCTV cameras:

Fixing CCTV camera problems and how to fix them
Recognizing the problems with your CCTV camera can be troublesome.

So, in this article, we have provided some tips to help you fix the issues.

Check the power and connection of the camera:
Sometimes, a problem can simply be due to a dropped connection, and the network may even just have a problem right now.

Internet Protocol (IP) cameras usually have LED indicators that are used to transmit data over the network. But this may be hidden inside the camera.

If the camera LEDs are not lit, you need to check if the camera is powered and plugged into the wall.

If your camera is mains powered and not battery powered, you will need to check that the camera is receiving the correct wattage, as a complex camera such as a wide-tilt zoom will require more watts than a normal plug-in will provide.

Ping and connections
Identify your camera's IP address by checking the camera list. Once you find your address, you can "ping" it from your laptop or smartphone to test the stability of the connection.

In the Windows search engine, type "cmd" to open a DOS command window. When the command window appears, you will be prompted to enter “ping” and your IP address.

You may see "Request Time Out" or "Destination Host Unreachable" messages. If these messages appear, check if your device is on the same network as the camera. If your device is on the same network as the camera, try connecting to the camera using your browser.

Remember the username and password
If you can ping the camera but are unable to connect, you may have entered an incorrect username or password.

If the reason for the failed connection is incorrect username or password, refer to the relevant manual.

Check ARP tables
Check the Address Resolution Protocol (ARP) tables, which are usually found in the camera-related sections.

Using ARP can make it possible to find a match between a MAC address and an IP address.
