Seven Advantages of IP or Network Camera Surveillance System

Seven Advantages of IP / Network Camera Surveillance System

1, the advancement: system use existing integrated wiring network transmission of images, and real-time surveillance. The system front-end equipment, attachment is concise, the back-end and only a set of software system.

2, reliability: the main equipment of WDR PoE network IP camera adopted embedded real-time operating system, the required equipment is simple, and image transmission is implemented through integrated wiring network, the reliability of the system is high.

3, price performance ratio: the required equipment system is extremely simple, system control by the backend software system implementation, eliminating the traditional analog surveillance system of a large number of devices, as a result of the image transmission through the network integrated wiring, saves a lot of video coaxial cable, reducing the cost.

4, security: system set up different levels of user permissions, only the highest authority of the user to set or change to the whole system, without permission of the user is receiving less than the image.

5, easy maintenance: the 3 megapixel waterproof IR h.264 CMOS IP camera installation of the system is simple, installation and use of the software system is also very simple. In the aspect of maintenance, system wiring is very simple, and the reliability of the main equipment is very high, maintain good performance, and can realize remote maintenance.

6, easy extension: when the need to increase surveillance points, surveillance host, only need to add 3MP outdoor vandalproof HD wdr dome camera can be through the existing network, without the need to change existing wiring system what to do.

7, wide range of application: using the network transmit real-time image, such as office, building inter-district remote surveillance: chain business, large factory room, the distal child care for the elderly, public building, there is no dangerous environment surveillance, surveillance, traffic regulation of all financial institutions branch, false alarms distinguishing, etc.

HDCVI Vs HD-SDI & IP

HDCVI Vs HD-SDI & IP

HDCVI Vs HD-SDI
Longer Transmission Distance:-
Both HDCVI and HD-SDI can transfer HD signal @720p/1080p, but HDCVI has a distinguished advantage at the transmission distance.
With general transmission media, HD-SDI reaches 100 meters at most while HDCVI, at least, transmits 500 meters by using 75-3 cable and featuring low signal distortion rate.
Better Anti-Interference Capability:
The anti-interference capability of HD-SDI solution is relatively poor when been placed against high-frequent radiation environment, which could lead to higher bit error ratio while the HDCVI adopts low-frequency modulation technology, making it free from the high-frequency wireless electric radiation to ensure stable video transmission at high image quality.
HDCVI Vs IP

Reliability:
HDCVI adopts P2P transmission to ensure a smooth and reliable transmission; while the transmission of network camera is based on Ethernet and thus may lead to network jitter and packet loss.

Real-time:
The network HD features video bu­ffer technology and the delay is controlled within 300 milliseconds in the general and fair networking environment; However, HDCVI features no latency capability for an outstanding real-time performance.

No Compression:
For HDCVI, there is no compression processed to maintain its original e­ect and thus present in vivid image quality.
Benefits of HDCVI Technology:-

Lower Cost:-
Unlike HD-SDI, which posts high demands on cabling and installation; HDCVI solution inherits the same installing means of conventional analog solutions, which is of great convenience and also decrease the cost.

Smart Control:-
As HDCVI transmits multiple-signal (video/audio and dual-way data) over one cable, it realizes video/audio synchronized transmission and reverse-signal transmission control at the same time, such as PTZ and zoom control; which further simpli‑es the installation.

Where To Use HDCVI CCTV?
HDCVI Cameras very useful where HighDefinition CCTV Cameras require at Lowcosts and all areas like Banks, Hotels, Restaurants, Residential Buildings, Apartments, Flats, Police Stations, Public Areas, Various Government Sectors, Private Sectros, etc.

Choosing Video Surveillance for SMB Owner

5 Top Points for Choosing Video Surveillance for SMB Owner
Video surveillance innovations have changed the landscape for users in the SMB (Small, Medium-sized Businesses) market in India. Improved security, reduced liability and peace of mind, along with useable video for real-time monitoring, Mobile Surveillance and forensic investigations, are some of the benefits now available to the SMB.

Following are top 5 points every SMB owner should be aware of when upgrading or implementing new video surveillance systems / CCTV surveillance systems.

Quality – One key to a successful system is the quality of the image. New high definition (HD/AHD) and megapixel IP cameras capture images in great detail, enabling the SMB owner to more effectively protect people and assets. Improvements in camera technology such as wide dynamic range (WDR), digital signal processing (DSP), and increased signal to noise ratios have helped create cleaner images with stable operation, allowing their use over a wide range of environmental conditions. State of the art technology enables low-light operation, outstanding 30 FPS quality and high standards with minimal maintenance.

Wide Selection / Functionality – CCTV cameras come in all shapes and sizes, in all price ranges with a multitude of features. It’s important that you know what you want to accomplish with the camera and not be influenced by bells and whistles. Cameras are available for indoor and outdoor applications, in dome or box configurations, and with or without audio capability. Network cameras can be accessed remotely, moved anywhere on an IP network and conveniently powered via Power over Ethernet (PoE). Digital technology has also enhanced the feature set of cameras with new and exciting capabilities. Advanced features include motion detection that can analyze video and respond automatically with actions such as tripping an alarm or initiating recording, freeing personnel from the need for constant monitoring. Image processing digitally removes ambient fog, haze or smoke to create the clearest picture. Other features include on-board recording to SD card, network failure detection, privacy mask and a variety of built-in video analytics features including active tampering detection and audio detect.

System Integration – One of the most compelling reasons for SMBs to consider new video surveillance technologies is the improved system integration capability. Open architecture and industry standards such as ONVIF, PSIA and H.264 have helped eliminate challenges once faced in designing a system. Now, best of breed designs can be put together to minimize financial impact while meeting security requirements with best available technology. Hybrid solutions further help preserve investments in infrastructure by deferring or eliminating the need to rip and replace systems that are still useful and functional. Additionally, the growing availability of integrated solutions like recorders with built-in software control and management capabilities enables the implementation of high performance, multi-camera HD systems with exceptional functionality, cost-efficiency and scalability.

Multi-Purpose Uses– New systems can offer the SMB options beyond video surveillance for improving business operations. For instance, video can be used to monitor daily operations and employee productivity. Not only can weaknesses or non-conformance issues be identified but the video system can be used to instruct the proper procedures. In retail environments, cameras can be integrated with point of sale (POS) systems to help with loss prevention. Video images can also be used to review consumer traffic patterns to assist the SMB owner in realizing optimum store layouts. The quality and reliability of the system makes the possibilities endless.

Technology Partners– SMBs may not have the staff or specific expertise and experience necessary to determine the kinds of products that will solve their particular issues, or to evaluate those products in order to choose the right one for the organization. By partnering with a trusted integrator who has knowledge and understanding of the systems, the SMB owner can better protect the value of the investment and help to ensure on-going satisfaction with the system.


The video surveillance playbook for SMBs has changed by becoming both more complex and more compelling. Taking the time to research and understand will help to make the decision process easier.
