what is cctv camera
Closed Circuit television CCTV records images of people in certain public places including town centres, roads, airports and on public transport CCTV images can be used as evidence in court. You can request CCTV recordings of yourself.
what is NVR in CCTV camera
A network video recorder NVR is a digital device which sits on your IP CCTV network to receive live image video streams and record them digitally to a hard disk.
How to Install PoE IP CCTV Cameras with NVR Security System
PoE IP CCTV Camera Installation Wiring with NVR – Step by Step
In the latest technology era, AI security and surveillance is taking the major role in protecting systems of sensitive areas with appropriate information than human being. The security systems also improved by designers e.g. DVR (Digital Video Recorder) system was the best system for local home user with less amount of Closed Circuit Television (CCTV) due to its price range as compared to NVR (Network Video Recorder) system because, they need extra switches and low maintenance. Nowadays, NVR comes up with built-in switch hub and power supply and replace the DVR system. As the NVR is network base system, it can be wired or wireless system with high range and can be used with multiple channels. There are some other differences between DVR and NVR but we will not go into details as we have already described them before and will focus on the NVR security camera installation wiring.
What is NVR?
NVR stands for "Network Video Recorder". As the name suggests, it is based on networking as the input signals are from a network as compared to a DVR where the input signals are based on direct wire connection. In NVR system, the video data encode and process at camera in digital format and send it to the NVR recorder to store it in a hard drive inside the NVR which can be viewed later by monitor or remotely if it is connected to an Ethernet router.
Keep in mind that only IP camera (Internet Protocol) can be used with NVR system as compared to DVR where analog camera is used. Moreover, NVR is a wire or wireless system where DVR doesn't support wireless system. Also, both PoE (Power over Internet) and Non-PoE cameras can be connected to the NVR system based on its design. In some NVRs, there is no built-in PoE system and you will have to buy an additional PoE and switch.
Before proper installation, check all the IP cameras locally to make sure they are working properly.
As external power doesn't need in PoE IP Cameras, therefore connect only the cameras through PoE via Cat5 / Cat 6 cables. You can use passive PoE splitter and PoE Injector and the wire length can be 130 feet (40 meter). In other cases, up to 35 Watts power can be transmitted over the internet and the Ethernet cable length can be 328 feet (100 Meters). In this way, the camera is able to transmit the video signal and receive the input power through the same cable.
Now connect the other end of PoE injector (Cat 5/ Cat 5 or RJ45) to the back side of NVR slots labeled as PoE input ports as shown in fig. If cameras are audio enabled, the white RCA cable should be connected to the Input slot in NVR for audio data transmission.
In our case, the power supply is built-in in the NVR system. So you can directly connect the NVR by three pin plug using 120V AC or 230V AC depends on your region. For smooth and reliable operation, it is recommended to connect the camera and NVR to the UPS (Uninterruptible Power Supply System).
To check if the system works properly, connect the PC / LCD / Monitor by VGA cables. For HD, Use the HDMI cable to connect the Monitor / Laptop with NVR as shown in fig.
You have done. Power ON the NVR and check if the live camera recording is showing on monitor as expected. You can configure the camera setting and IP by the user manual provided by the manufacturer.
The following fig shows a typical PoE IP CCTV cameras security system with NVR.
