PTZ security camera has been used to build video surveillance and security system to get property and humans secured. With the ever-expanding demands on security cameras, there are various types of security cameras produced and applied in practice, such as analog cameras, IP cameras, PoE cameras, etc. No matter which types of cameras are being installed, the security camera system set up mainly to solve two issues, one is the network, and the other is power. Long distance outdoor setup generally exposes more challenges and difficulties for some objective and subjective reasons. Today, we are going to introduce a cost-efficient solution that can solve the power and network issues for PTZ security camera that integrates PoE, fiber, and remote DC power.
Lacking a local AC power outlet is a common problem to get PTZ security camera install at the desired location. PoE PTZ camera comes out to solve this problem perfectly. PoE (Power over Ethernet) is a widely used power networking cabling method for low voltage IP devices setup, as it enables twisted Ethernet cable to carry power simultaneously for connected edge IP devices, that said, in this way, the present AC power source can be eliminated as power and network are transmitted together from the main network device over a single Ethernet cable. In short, PoE gives great flexibility on camera placement and connection.
Utilize PoE PTZ camera to install over a long distance, directly running long length Ethernet cable for connection won’t make sense. You should aware that either common IP camera or PoE camera, both rely on Ethernet cable as for data or PoE transmission medium, while Ethernet cable can only reach a 100 meters(328 feet) or less transmission distance due to power loss and voltage drop. Therefore, only extend the length of the Ethernet cable is useless as only a weak signal and deficient power are extended to the remote PTZ security camera. We can choose fiber optic cable as the data transmission medium to overcome long range deployment. Fiber optic cable is made from glass or plastic that are much thinner than hair, and it makes use of light to transmit the optical signal that only with data. Fiber optic cable only deals with network issues for the PTZ camera. Power requires separate consideration. For these reasons, fiber optic cable is capable to provide greater distances up to 1km, 20km, or 80km.
PTZ camera stands for Pan-Tilt-Zoom camera, and it is a kind of camera that is generally used for large coverage monitoring with its pan, tilt, and zoom functions, and for a clear image result. Video quality and its upload speed matter the performance and utility dramatically. High definition lens and network speed that the network serves are the keys to receiving effective surveillance and security. And bandwidth is the crucial related factor need to be considered. Generally speaking, the higher resolution and the higher upload speed are demanded, the higher bandwidth is required. Otherwise, a clear image can’t be viewed on the monitor or mobile phones, especially when the video data run over an ultra long distance because of the signal loss in copper Ethernet cable, and deficient bandwidth may result in latency for video upload to the internet and download to local monitor or mobile devices. To be honest, quite a few consumers opt to choose fiber optic as the connection to address the low bandwidth issue and get an improved surveillance system. Fiber optic cable offers high bandwidth with low latency even after a long run, which means it is able for the PTZ camera to have a higher potential receiving gigabit network speed if using a pair of fiber media converters to build the link for a video stream.
When deciding to use fiber to get an extended Ethernet or PoE for PTZ security camera in long distance outdoor setup, apart from the above advantages, the connection using fiber optic cable is able to experience less electromagnetic interference as no current through the cable, and it is known that outdoor environment always has a higher possibility to encounter lightning or other weathers easily trigger EMI. Therefore, a more reliable connection paves the way for continuous video surveillance. Moreover, fiber optic network is relatively safe from cybersecurity threats like hacking because the data is more difficult to tap in and change.
Actually, the whole connection is involved in copper and fiber. At the main end, a networking device like router, network switch output with copper cable, and at the edge end, the majority PTZ camera only receive power and data through copper cable too. That being said, we need to convert copper and fiber signals for each end. Generally, there are two common options, one is the PoE fiber media converter, and the other is the fiber PoE switch, which needs to be powered to work. In the beginning, it is said that PoE can eliminate the local power source for the PTZ security camera. And from what was mentioned previously, having known that fiber optic cable only transmits data, and power requires a separated solution. Then the problem comes, how to solve the power for the signal conversion network device if there is no way to access a present AC power outlet?
To sum up, complicated situations like which need to install at remote locations away from the main network, and may demand a high bandwidth remained over long run, and may be hard to get AC power outlet from the present site, can be solved with the PoE over Fiber with DC Power System conveniently and reliably.
PoE over Fiber with DC Power System
To address power and network issues for PoE powered devices and fiber network devices that are plan to be installed at outdoor long distance locations, Fastcabling produced PoE over Fiber with DC Power System. This system is well-integrated PoE, fiber, and DC remote power in one link. The system adopts fiber optic cable for Ethernet extension to break the 100-meter transmission distance limitation and provides PoE fiber copper conversion tool to supply PoE to the edge PoE powered devices(PoE PTZ security camera), and allow low voltage DC power source place at the main network end where is far away from the PoE fiber copper conversion tool. Power and data are transmitted from the main network end and provide extreme flexibility and convenience for system setup. Want to know more benefits offered by the system, the blog article PoE over Fiber with DC power system Explained & Startup Guide can meet your need.
The system mainly relies on the 5844-46 Waterproof Industrial Hardened Grade Fiber PoE Media Converter. It does not only work for fiber to copper or copper to fiber signal conversion, and output PoE for connected PoE powered devices and is also the key to realize remote DC power sending from afar(main network end or other locations) to the media converter because of its wide input voltage range from 24V-56V, it can adapt the distance with a regulated voltage. This media converter supports a gigabit network to meet the high bandwidth requirement of the PTZ camera or other applications that need demanding bandwidth. And Its IP68 waterproof and dust-proof rating rugged housing makes it suitable for outdoor deployment.
The fiber Power Termination Box is the other significant tool to build the system. This termination box is of great use on cable and connectors routing, distribution, management, and protection. With the assistance of this box, power and fiber can be managed together and you are able to get a fixed fiber network power infrastructure under preparation, when a new IP device needs to install, then take the corresponding cabling to finish the connection with the easy plug-and-play job.
If you have questions about installing a security camera system with fiber or PoE, the Fastcabling support team is waiting for your contact and strives to provide dedicated support that is useful for you.
