This summer I built three surveillance system. All of them use the mobile Internet and allow you to watch videos from the cameras on a smartphone, located anywhere in the world.
I'll tell you how to construct a video surveillance system at my dacha.
Dacha two IP FullHD-camera installed (you can put up to eight cameras), implemented motion recording and remote viewing of the cloud. Backup battery allows the system to operate without electricity in the network up to 10 hours.
The whole system is mounted within a metal enclosure with protection from moisture for the standard IP55.
Inside the box is a block of uninterrupted power supply of 12 volts, the IP-Video, a router.
3G-modem to the USB interface is placed in a jar of Actimel inserted into one of the two communication orifices of the cabinet. Due to this, the modem perfectly catches the signal of the cellular network at the same time remains as it were, inside the waterproof enclosure.
the third chamber can be added without any modification to the system. If you reconfigure the router to the WAN-port it turned into another the LAN, it will be possible to add a fourth chamber. To add another four cameras need to install a 5-port LAN switch (switch) have replaced by a more powerful power supply.
camera
I used a metal outdoor dome Camera AZISHN on SONY IMX323 sensor.
The camera is located on the fence wire from them fixed so that they are not visible from the street.
They provide an excellent picture FullHD day and night acceptable.
recorder
To record video from a camera using the DVR Super Mini NVR Enster N9000-8EX.
The Registrar wrote to the usual 32-gigabyte flash drive connected to one of its USB connector. In fact, I ordered a 4-channel recorder, but has twice come more expensive eight-channel. Now the third way, let's see what comes.
the Internet
For remote access to the system used free mobile internet Danycom. One gigabyte, provided free of charge tariffs, enough to spare. Danycom is a virtual operator on the Tele2 network.
It turned out that I have in the country is very It does not work 4G Tele2 network, but 3G works fineSo using a USB modem 3G, which I I unlocked to work with SIM cards of any operator.
The modem is connected to the Internet center (router) Keenetic 4G III. To him the same cable to connect the recorder, it is connected to the camera - the router 4 LAN-port, and with the help of settings can also add a fifth, making WAN-port on the LAN.
Kinetic is ideal for use in country surveillance for several reasons: first of all, it works with all modems, and is able to "Juggle" their nutrition hangs due KeenDNS service can be accessed at the interface of the router from the Internet, and in my case even reboot the recorder (this will write more in the section Power), and finally, it is cheaper - to Avito easily find it for 500 rubles.
Nutrition
As used me recorder requires a 5 volt power supply (connector MicroUSB). I have done a clever thing - soldered cable adapter, which is both the USB-extension cable for the modem. To the USB connector to solder a second cable to the connector MicroUSB, supplies power to the registrar of the kinetics. So I "killed two birds with one stone": and decided to issue 5-volt power supply and has the ability to remotely forced reboot registrar (as I wrote above, the kinetics can turn off and turn on the power on port USB).
I modified BBP, Having taken from it a high-voltage part in another place, but you is not likely to be needed. The BBP stands Battery 12 volt 7 amp-hours. At power failure the two chambers, the registrar and the router to the modem operate on it to 10 hours.
Power supply 12 volts is applied to the five-pin pads WAGO 222. They plugged the power cord of the router and the wires from the cameras.
The cameras are connected street UTP cable. The unused pairs in the camera's power is applied (Passive POE). I do not use any adapters, and a crimped RJ45 connectors on the orange and green pairs. Both the blue wire pairs are connected to the positive side, both brown wires to negative (logically should have been the other way around, but in all the adapters plus it is blue, so I did the same). From the side of the cabinet wires simply connected to the blocks WAGO, to the chambers, they are connected to power socket screws.
review
To view XMeye used mobile application. To it is connected and the registrar and separate camera (even if the registrar for some reason stops working, you can watch the video from the cameras, but will not be able to watch the recording).
How much is
I calculated how much I spent on this system. Not all of my expenses are required (for example, you can eliminate the use of a metal cabinet, and instead of an uninterrupted power supply to use normal).
Camera 2 x 1400 = 2800
Registrar = 1400
USB flash drive 32 GB = 0 (I had, if you do not, add the cost of flash or MicroSD card)
BBP = 700
Battery = 0 (I was a new costs about 500 rubles).
Keenetic 4G III = 0 (I gave it to the manufacturer, b / y by Avito can be found for 500 rubles).
Modem 3G = 0 (lying, for sure, and you are lying).
Cable 20 meters = 300
Wardrobe IP55 = 1150
Connectors, WAGO, box = 100
Total: 6450 rubles.
If everything, including a router and a modem to buy new, the price will rise by half, but I do not recommend - modems and routers to Avito sell for pennies.
Appointment of my control systems - from time to time to watch and make sure that the country is all right. If you aim at CCTV protection from intruders, you need to put the camera in the house more cameras on the street in the most inaccessible places, and of course to place the recorder where it is not the villains find. In addition it is important to equip the house alarm system with motion sensors.
The system has been running for a month and no crashes and hangs in that time was not.
