Many users have made it difficult to install a monitoring system. I don't know if I should choose an analog camera or a network camera. Analog cameras are cheap, network cameras are more expensive, and two-phase trade-offs are made. Many users make decisions about price advantages, and this is often where the analog camera's breakout space is.
Indeed, in the surveillance market, network monitoring has always been a controversial topic. From the perspective of development needs, the advantage of network monitoring is unmatched by analog surveillance. However, the delay in analog monitoring and delay in the market has also caused more reflections. For users, the choice of analog monitoring or network monitoring is also based on their own needs and the performance of the product itself. The imaging effect is still the whole system budget, I believe that every user has a flaw in his heart.
So, what is the difference between an analog camera and a network camera? I believe that everyone can literally draw a rough definition, that is, network cameras can be networked, analog cameras can not, and the specific difference? The author below to summarize.
First of all, the concept should be clarified:
The front end of the analog camera uses an interlaced CMOS/CCD sensor to convert the optical signal into an analog electrical signal, which is then output to the DSP. The DSP performs A/D conversion and color adjustment processing and then performs D/A conversion to PAL/NTSC TV. Signal output.
The network camera is a new generation of cameras combined with analog cameras and network technology. It has an embedded chip and an embedded real-time operating system. The video signals transmitted by the camera are digitized and compressed by a high-efficiency compression chip and transmitted to a Web server over a network bus, enabling authorized users to view, store, and manage video data at a local or remote location through a scaled IP-based network infrastructure.
Second, the performance is very different:
First, clarity. Seeing more clearly is the goal pursued by every user and the ultimate mission of the security industry. The current clarity of network cameras and analog cameras is not comparable. At present, network cameras can already achieve image output of millions, 2 million, 5 million or even 10 million pixels, while analog cameras can only output images of CIF and D1.
Second, manage the differences. The webcam has a built-in WEB that manages and views images using a standard WEB browser on a PC. At the same time, the network camera can also realize remote management and image viewing, and the image data is stored on the remote hard disk, which is easy to search, easy to store, and will not be destroyed. The analog camera is relatively a closed system and can only be monitored internally. Look, you can't monitor it remotely. Video data can only be stored locally, and it can't be viewed remotely. It is easy to be destroyed by criminals.
Can you boost your WiFi signal with outdoor 4G CPE?
When you travel or go to some remote areas, you may be annoyed by poor reception. Is there any way to get a strong WiFi router signal outdoors in a 4G LTE network? Very good, outdoor 4G CPE router would be a good choice!
What is an outdoor 4G CPE router?
An outdoor 4G CPE router differs from a Wifi-only router in that it needs to be connected to a fiber optic network. The 4G CPE WiFi router can pick up the carrier's 4G LTE network signal and convert it into broadband and Wi-Fi. Just plug in your SIM card with your data plan and enjoy a stable and reliable WiFi signal with family and friends. This Outdoor CPE can be used in harsh environments. If you install your router outside or near a window in an area with a weak 4G signal, your device can receive a better 4G signal.
Second, what are the characteristics of outdoor 4G CPE router?
1. Better network for ODU and IDU
4G CPE outdoor routers include an outdoor unit (ODU) and an indoor unit (IDU). Help your device receive the best outdoor cellular signal through the ODU, and connect to the indoor WiFi router through the network cable to experience better network speed. As shown in the figure below, an outdoor LTE CPE (ODU) is installed outdoors and connected to an indoor Wi-Fi router (IDU) via a network cable. The entire 4G device is powered by POE. This data will be transmitted over the same Ethernet cable, eliminating the need to connect the ODU to a power outlet.
2. High-speed multi-user available
The outdoor 4G CPE features a built-in 4G LTE modem and a 5dBi high-gain antenna. LTE CAT4, download speeds up to 150Mbps, WiFi speeds up to 300Mbps, can connect 32 users at the same time. The high-gain antenna of the outdoor 4G CPE router enables it to have higher power and stronger signal transmission and reception capabilities than mobile phones. Therefore, the CPE router can receive the signal. If your phone can't receive a signal in some areas. Sometimes you also use your phone as a hotspot to share Internet access with your friends, right? Similarly, this 4G LTE CPE router allows 32 users to connect to WiFi at the same time, allowing more users to connect and receive a better signal than a phone sharing hotspot. In addition, the IDU has four Lan ports and can be connected to the device through network cables, which is also a backup mode of the Internet.
3. Excellent outdoor performance and design
On the one hand, outdoor LTE CPE is waterproof, UV resistant and corrosion resistant. It can be used at -20℃~60℃ operating temperature. Therefore, it is ideal for outdoor deployment. On the other hand, there are a variety of installation methods. CPE can be mounted on Windows or walls by mounting brackets. It is also possible to attach it to the antenna mast. In addition, the signal strength is displayed through the LED indicator to facilitate users to find the best location to get a better 4G signal.
4. Support different frequency bands
Outdoor 4G CPE supports a variety of frequency bands, including LTE-FDD, LTE-TDD, 3G WCDMA, and 2G GSM network bands. Meet the needs of different frequency bands in different regions and make full use of network resources.
5. Convenient management of CPE
Start the Web browser to log in to the Web management page. You can configure and manage the CPE easily. The web management system supports Linux. Provides functions such as WebUI management, Telnet, SSH terminal system status monitoring, NTP client, synchronization between devices and the system clock network, and configuration file import and export.
6. Applicable to various application scenarios
CPE is designed to provide ISP or operator with 4G LTE outdoor wifi router to facilitate network connection, whether at home, or in enterprises and remote areas, to bring users a wonderful network experience.
All in all, an outdoor 4G CPE router is an excellent choice for connecting to the Internet in remote areas and places where the signal is weak, the wired network is unreliable, or there is a lack of reliable WiFi. It's worth deploying outdoor CPE in rural, coastal, boat, caravan, campsite and remote areas to enjoy the best network speeds and outdoor activities! It can even reduce complex cabling deployments for home networks without the need to install a wired fiber network.
