How To Build Small Spy Cameras

When choosing to employ IP network cameras for your residential or commercial security camera system there are a few things to take into account. This article volition focus on clearing up some mutual questions regarding Network IP Cameras and NVRs (Network Video Recorders). In society to clarify some of the topics covered, I volition often refer to "Techpro Security Products" make of NVRs and cameras.

Analog Cameras & DVRs
First, it is of import to empathise some differences betwixt IP cameras and analog cameras. In virtually cases, an analog camera merely sends the video signal back to the DVR over a coax cable. The DVR is where the encoding and recording is done. It also contains the software for managing the camera settings and camera options. You lot tin access and modify each camera's settings through the DVR itself. The DVR also provides the ability to view the cameras in real-time and review recorded footage. Without a DVR you would non exist able to tape or view recorded video.  Essentially the DVR is the brains of an analog security organization. Usually, analog cameras are powered with a 12 or 24 volt power source.

IP Cameras
Network IP cameras, on the other paw, are standalone units that can exist accessed via the camera IP address. All of the software and settings (the brains) are embedded in the camera itself. Many IP cameras also have an SD carte for storing recorded video. IP cameras are just like any other computer or smart device that is attainable on your network. IP cameras utilize CAT5 or CAT6 to transfer the video, and in most cases tin can be powered over the same cable when use in conjunction with a POE (Power Over Ethernet) switch.

Essentially this means that yous can have i IP camera on your network or several if you choose. Each IP camera would have its ain user interface and specific settings that can exist viewed or managed individually by going to the IP accost of each camera and logging in to it.

Viewing Multiple IP Cameras Simultaneously
As you might judge, if you have multiple IP cameras, it quickly becomes a hassle to take to go to unlike IP addresses and log into each camera individually in order to view in real-time or re-view recorded video.

Then, what practise yous need to view all of your IP cameras in one place? The reply is anNVR (Network Video Recorder). You can think of an NVR as a hub with a single IP where y'all tin view all of your cameras simultaneously. The NVR tin can too house a hard bulldoze(s) to store the recordings of all your IP cameras and dramatically increase your storage capacity.

IP camera compatibility
Because each IP photographic camera has its ain user interface and photographic camera options built into the photographic camera itself, not all IP cameras are completely uniform with all NVRs. Next I will talk most the diverse IP camera compatibility options.

Compatible Network IP cameras and NVRs
Your best option is to buy network IP cameras that take a uniform NVR. This means that the manufacturer of the cameras specifically designed the NVR to be uniform with the user interface, software, and options that are embedded in the photographic camera itself.

For purposes of this instance we will talk most the "Elite" line and "PRIME network IP lines by Techpro Security Products. If you lot were to buy Elite IP cameras along with an Elite NVR, yous tin look that the cameras will work seamlessly with the NVR. This means that all of the camera options and functionality are directly accessible and configurable through the NVR itself. In that location is no need to log into each camera individually for the initial setup or to admission the camera's functionality thereafter.

The aforementioned tin can be said for the PRIME IP line. If yous were to buy Prime IP cameras with a Prime number NVR you are guaranteed to accept total functionality directly through the NVR.  Buying IP cameras that are fully compatible with the NVR tin can brand for a fast and convenient setup too as streamline the maintenance and usability of your new security camera organisation.

The ONVIF Protocol
What if you already have IP cameras and but desire to replace your NVR or vice versa, you have an NVR but yous want to add new IP cameras?

All cameras use a specific protocol for advice between the NVR and the camera itself. One of the nearly mutual protocols is ONVIF. In nigh cases, if the photographic camera is ONVIF compatible it volition be able to communicate with an NVR that is also ONVIF compatible. This means that you are guaranteed to get video output from each photographic camera to the NVR. But in many cases, not all of the cameras functionality volition exist available directly through the NVR.

TechPro Security Products too has a TP line of IP network cameras. The TP line uses the ONVIF protocol and can be used in conjunction with the Elite NVRs, Prime NVRs or any ONVIF compatible recorder.

When using ONVIF, it is recommended that you log into each camera individually to configure the settings at the camera level prior to installing or mounting it.  Once all of your cameras are configured the fashion you lot like, y'all are ready to install them and video will be transferred back to the ONVIF uniform NVR.

Some common things you will want to set upwardly on your ONVIF cameras include but are not express to the following:

The Camera IP accost – If the cameras you lot are using do not accept a DHCP option y'all will want to manually assign each photographic camera a unique IP accost to avoid IP conflicts on your network.

Main Stream Resolution
Extra Stream Resolution
Appointment & Fourth dimension Format
Camera Label
Movement Detection
Motion Masking
Color and Contrast settings
IR Configurations

It is likewise recommended that yous update the camera firmware at the fourth dimension of setup every bit information technology may not be able to be updated through the NVR.
