I have a home video surveillance system has been running for eight years (https://ammo1.livejournal.com/49699.html). It is based on analog cameras and DVRs. Now I plan to buy a simple IP-Surveillance system.
Modern IP-camera can operate without a registrar - it connects to the network and the Internet via Ethernet cable (there are models and WIFI), and allows you to view an image both in the local network on your computer or smartphone, or via the Internet, with thanks to the use of cloud services, it does not require the real IP-address and protoss ports.
The camera has a WEB-interface settings.
There are motion detection, configurable mask covering part of the image, and many more features.
Most cameras use the H264 codec, but there is a camera with H265 support, the compressing video stream is 3-5 times more for the same quality.
There are cameras with recording on MicroSD-card, but do not forget that someone could steal a camera together with the recording.
There are cameras with the ability to rotate, sound recording and speaker, which you can send voice messages.
If multiple cameras or want to share geographically place where there is only one camera, and the place where the recording is carried out, you can use the DVR. The vast majority of IP-based cameras support ONVIF protocol by which the registrar communicates with cameras.
Most recorders also support cloud-based services and allows to remotely view images from the cameras and control the operation of the registrar through the Internet.
There are several types of recorders.
The smallest and cheap recorders only work with IP-cameras and is used to record an external hard drive with USB or eSATA or MicroSD card.
There are plenty of registrars, which is placed inside a 3.5-inch hard drive.
Hybrid recorders work in conjunction with IP-cameras and analog cameras, including high-definition (AHD, XVI, CVI, TVI).
There is one problem. Many DVRs can not independently detect motion and use commands from the camera, and many cameras do not transmit the commands. The result is that the recorder can not record video on motion and the only way to write the video continuously.
To connect IP-based cameras to the recorder require an additional Ethernet-switch. Also need a 12-volt power supply for the cameras. If the recorder is powered by a 12 volt power is usually its power supply and enough for him and the camera and can be powered from him. The majority of IP-based cameras a separate power plug, but there are those that feed directly via Ethernet cable (POE) for such cameras need a switch with POE or POE-injector.
I plan to buy yet for experiments H265 small recorder for $ 22.
AND H265-chamber metal dome for $ 28.
If you know more interesting options, share! :)
