WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both Wi-fi and PoE at same time. If you hook up the IP camera to your router, you have to choose one of them, either Wi-fi or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the set up environment and research which functions you want to achieve.
Wireless or PoE, which is a good? As a mature technician that has four years in video recording surveillance industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transfer data through wireless signal (2.4GHz UHF music group, 5GHz SHF strap).
Obviously, once the IP camera facilitates Wireless, the camera can connect your router without needing hardwired connection. WiFi can permit IP camera become lightweight, this is the advantage of Wireless.
But there are two downsides on WiFi, which can be; every gadgets require power supply, that means your IP camera still requires cable television for connection.
Up to now, I haven't found any IP cams have the ability to operate with electric batteries.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does indeed Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we've a lot of things to consider including ability rate of Wi-fi device, environment (indoor or outdoor) and even more.
Typically, a home/office router (TP-Link) provides WiFi coverage reaches up to 10 meters inside.
When Wireless devices will work outdoor without hurdle, the transmitting distance will be much considerably.
To extend the WiFi coverage or distance, you can set up WiFi access point. This gain access to point (or hotspot) has a range of about 20 meters (66 ft) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power supply over solitary Ethernet cable tv (Kitty5/6) is the main feature of PoE technology.
As long as your IP camera helps PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP surveillance cameras support plug-and-play assembly, which greatly reduced the unit installation procedures, and eliminate the necessity of vitality cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum ability rate is to 15.4 W of DC ability (bare minimum 44V DC and 350mA) to each device.
To be able to provide power for high power utilization devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of electricity.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Downsides AND PROS OF POE TECHNOLOGY
Let's firstly discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet cable tv, no need extra power cable or power supply.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmitting is through wired cable connection, there is no signal disturbance, no transmission jamming.
For properly working of PoE devices, Electric power sourcing equipment (PSE) is vital component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is a lot expensive when compared to a traditional network move, which increased a little on cost.
#6. Wi-fi VS POE
No best solution, only right solution. If you wish to install a unitary IP camera for home monitoring, you can opt for Wireless IP camera.
Guaranteeing the WiFi IP camera is installed within coverage of your Wi-fi router.
For more than one IP camera, PoE is recommended. PoE is much reliable than Wireless in conditions of data transmission.
Furthermore, an IP camera system based on PoE is much easier to manage, centralized ability solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of security market, I found that WiFi IP cameras are widely used for non-professional in house security, and PoE IP video cameras are installed for outdoor monitoring system. But if you choose Wi-fi IP Camera please read article below.
So how can you determine which wireless IP camera suits your needs?
Firstly, establish the thing you need. Many customers often don't really know which type of cordless IP camera suites and would meet their needs. As a result, they get sucked into buying cordless IP cameras that are beyond what they need.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be located in? (Hallway, outdoor, low light or bright); what precision of data would you like to catch? (HD images with or without sound) & most importantly, what is your budget?
Subsequently, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Needless to say, this feature will be based upon the environment where you want to use the camera.
A wide skillet and tilt range is never a negative thing.
Thirdly, zooming capacity for the wireless IP camera is also essential.
Ensure that you check the sort of zooming capabilities, whether its optical or digital.
Most of the IP cameras on the market are digital, but you will never fail to find one with optical focus.
Fourth, test the gear before purchase.
That is vital, in particular when you are buying from your neighborhood electronic store.
Always request for a test installation as this will permit you to look for the picture quality of the camera.
Furthermore, it will offer you an possibility to learn how to set up the equipment in a proper manner to make sure that you receive the best image and audio tracks quality.
