How to provide power backup for CCTV camera?
CCTV camera, as the core part of video surveillance solution, often shoulders the important function of security. The basic condition for the normal operation of CCTV camera is stable power providing. However, stable power providing is difficult in many developing countries. Power outages, unstable power grids, overvoltage and undervoltage of power supply are common. In the case of unstable power grid, how to provide power backup for CCTV camera becomes the premise for the stable operation of the entire video surveillance network.
Common cases of power grid instability
Generally speaking, there are two main situations in which power grid is unstable:
The site has power supply, but it is unstable
When the site is outdoors, the voltage of the power grid is often not as stable as that of the in-building power grid. The voltage is prone to undervoltage or overvoltage. When this happens, if there is no good protection and power backup, the CCTV camera will be powered off. The following figure shows an example of an Edgeware outdoor CCTV camera site. The standard power grid voltage in this area is 120VAC. As shown in the figure on the right, its voltage drops to 95VAC for a moment, which constitutes an undervoltage event.
The site lost power
In most cases, the power grid of the entire site is offline. This situation is very common in many countries. The power grid is offline for 1-2 hours. Some African countries even have electricity for only 4-8 hours a day, and the power grid is offline for the rest of the time. In this case, it is even more important to do a good job of power back up for CCTV cameras.
Power Backup for CCTV Camera Solution
The Power Backup for CCTV camera solution Edge Span U60-LSP-7 designed by Edgeware based on the experience of outdoor CCTV camera deployment is an all in one system. It contains the following main components:
1) Power System
The power system is overall high integration design contains high-efficiency UPS, complete electricity protection and high-performance long-life battery. The main functional as follows:
• 300W High Efficient DC-UPS
This DC-UPS is developed by Edgeware dedicated to the outdoor applications. Because of the harsh outdoor environment, the Edge Span U60 DC-UPS system adopts a high-stability design and is optimized for high-temperature environments to ensure long-term outdoor project deployment. Work stably and reliably.
At the same time, U60’s DC-UPS system provides a complete monitoring and management function, which is collected by Edgeware’s Convergence Monitoring Unit and uploaded to the Convergence Management Software Platform to remotely monitor and manage the working status of the UPS.
• 48V 10AH Lithium Battery
The system is equipped with a 48V10AH lithium battery by default, which can provide 480wh of electrical energy for the system.
• Monitoring Unit
Monitoring unit is the core module of Edge Span U60 for monitoring and management. Monitoring unit and Convergence software platform can provide monitoring with Edge Span U60 complete system such as DC-UPS, surge suppressor, environment, battery, external sensors etc. So that the customer clearly knows the status of the site, and prepares the corresponding spare parts before the engineer arrives at the station for maintenance, which will not cause multiple on-site repairs, thereby reducing Opex.
• ES33058PFM-BT Industrial POE Switch
The ES33058PFM-BT is a Gigabit L2+ managed industrial PoE switch. It has 2*100/1000Base-X SFP ports and 8*10/100/1000Base-T adaptive RJ45 ports. Downlink Port 5 ports can support IEEE802.3af/at PoE standard. Single-port POE power up to 30W. 2 ports support 802.3bt 110W POE++.As a PoE power supply device, it can automatically detect and recognize power-compliant devices that meet the standard and supply power through the network cable. It can supply power to POE terminal equipment such as wireless AP, IP camera, VoIP, and industrial sensors through the network cable, and meet the network environment that needs a high-density PoE power supply. It is a system that Edgeware designed for outdoor deployment.
Please pay attention , when ES33058PFM-BT switch installed in Edge Span U60-LSP-7, downlink port 8 is occupied by monitoring unit.
