Sigrand Distributed Video Surveillance System
In this review I want to talk about the equipment of our company for building video surveillance systems. There are many IP cameras, switches, thermal housings and other equipment with very similar characteristics on the market, so I will try to focus on the distinctive features. Under the cat, you can learn how you can connect video cameras in a chain to one port of the switch, smart thermo housings and multi-kilometer PoE extenders.
Let's start with camcorders. The model range is limited to the Sigrand SG-1C-xxx line in a standard package without an integrated lens.
The cameras have a modular design, which allows to produce modifications in the same case with different sensors, processors and network interfaces.
Currently using a Texas Instruments DM368 processor and two types of sensors with wide dynamic range support (WDR or HDR). Also, there are all the standard attributes of modern cameras: mechanical IR filter, h.264 encoder 1920x1080 30 frames per second, support for ONVIF.
Now about the features. As you can see in the picture, the SG-1C-111 and SG-1C-121 cameras have two ethernet ports. Inside there is a three port switch that allows you to connect up to three devices to the network. The MII interface of the camera is connected to one port and the remaining two are brought outside. If we connect a switch to one of the external ports, and another camera to the second, we get the possibility of a serial connection. That is, you can “hang up” a chain of cameras on one switch port. Passive PoE technology is used to power the camera chain; power is supplied through two free pairs and passes through two external ports of the camera through.
The maximum possible number of cameras in the chain depends on three parameters: the power of the PoE injector, the power consumption of the cameras and the distance between them in the chain. If you use the MS-17E8PP module with a power of 60W per channel as an PoE injector, you can connect up to 12 cameras, with a small distance between them. If the distance between the cameras is the maximum possible for Ethernet 100 meters, then the number of cameras in the chain is limited to 5 pieces. The length of the chain, from the switch to the last camera, will be 500 meters. This becomes possible, due to the operation of the cameras at PoE lowered to 30 V. We call this connection “end-to-end” PoE or PoE-through.

Sigrand SG-1C-112 and SG-1C-122 cameras have a built-in SHDSL modem, which
allows you to transmit a 2 Mbit video stream at a distance of up to 8 kilometers using a standard cable with a cross section of 0.5 mm. To power the camera at this distance, a constant voltage of 240V is used along the signal line. This is a fairly common technology PoDSL (Power over DSL). To connect cameras using this technology, the MS-17H4P2 module is used.
Online broadcast of our cameras and not only ours can be viewed here.
Sigrand SG-1H-W1 and SG-1H-I1 Housings are the first smart PoE Housings with a spotlight.
The housing is controlled by the built-in microcontroller and is configured via the RS-232 port. There are three temperature sensors: diodes, inside and outside the casing. A powerful radiator and two fans are used to cool the diode array. The casing has two modes of operation - autonomous and controlled through the RS-232 port. In standalone mode, you can use cameras of any manufacturers with PoE support. Adjustable thresholds on and off the spotlight, the distribution of power between the camera and the spotlight, on and off fans and so on.
If you use the thermal enclosures in conjunction with Sigrand cameras, then all processes can be controlled via the web interface, as well as sequentially connect several thermal enclosures to a single switch port using PoE-through technology.
The basis of the system for building a distributed video surveillance system with remote power supply is the Sigrand SG-17S switchboard - the only device on the market with the ability to install different interface modules - SHDSL or Ethernet.
As standard, it comes with a 240-watt power supply and two 10/100 / 1000BASE-T / SFP ports. It allows you to connect: up to 32 video cameras with Ethernet interfaces (PoE class2 - 7.5 W), up to 16 illuminated thermal housings (PoE - 15.4 W) and up to 16 PoDSL cameras. Price $ 699.
Now there’s not much about the modules for the SG-17S platform: the maximum number is up to 4 pieces, support for PoE and PoDSL interfaces.
MS-17E8PP (8 x 10/100 Ethernet PoE +)
8 port PoE module. Supports remote device power technology by free pairs (in Passive PoE mode). Maximum power up to 60 watts per channel. The price is $ 239.
MS-17H4 (SHDSL 4 x 15.2 Mbit / s)
4-port module SHDSL. The maximum speed for each interface is up to 15296 kbps per pair. Price $ 379.
MS-17H4P2 (SHDSL 4 x 15.2 Mbit / PoDSL)
4-port PoDSL module. The maximum speed for each interface is up to 15296 kbps per pair. Provides 240VDC remote power to each interface. The maximum power of the connected devices is up to 17 watts. Price $ 559.
By combining different modules, you can connect multiple cameras and thermal enclosures to one Sigrand SG-17S device, closing almost all ranges of distances.
If you need to connect and power one PoE camera over a long distance, you can use our new SHDSL modems Sigrand SG-17B-261 and SG-17B-351.
SG-17B-351 ($ 409) takes power over PoE and injects it into the PoDSL line,
on the contrary, SG-17B-261 ($ 359) receives 240V from the SHDSL line and injects PoE.

Prospective, in our opinion, the development of which we are now engaged in:
1. Single-channel Passive PoE injector 15 - 60 W (from $ 10 to $ 20)
2. Switch 2 ports 10/100 / 1000BASE-T / SFP + 4 PoE ports 60 W, in desktop or street version (from $ 200 to $ 300)

4. Sigrand SG-3C-xxx outdoor cameras, the cheapest camera line, a competitor to Ubiquiti Air, only with a varifocal lens and a 2 megapixel sensor. ($ 150)
5. Modular router + switch + NVR + Sigarnd SG-18S repeater, on a powerful network processor freescale P10xx / P20xx, 3 ports 10/100 / 1000BASE-T / SFP, 3 expansion modules, HDD rack, power supply up to 1000 W. It is theoretically possible to connect to the device and power up to 200 cameras. The software will be a modified version of momentvideo.org
6. VDSL2 modems and modules for cameras and switch.
6. White or infrared searchlight with adjustable power up to 15 W, powered by PoE and the ability to connect to the chain.
Let's start with camcorders. The model range is limited to the Sigrand SG-1C-xxx line in a standard package without an integrated lens.
