Document Definition:
This document defines the specifications (i.e., introduction, technical features, deployment and maintenance
methods) of the WiSen Vision Unit, which is one of the key components in Wisen Low Power, Intelligent, Wireless
Sensor Network (WSN) Monitoring system. It is responsible to:
Capture high-definition images (8MP) even in ultra-low light conditions;
Issue visual (LED) and audible (buzzer) warnings on-site;
Form a time-synchronised WSN with other nodes in the system;
Transmit image data to a server via public wireless network or local WiFi / cabled network connections.
Overall, Vision Unit follows the basic procedures as shown below:
Imaging: All Vision Units capture images periodically at interval T;
Trigger Listening: The built-in radio chip listens for trigger ping signals from nodes on the same frequency
band for activation;
Activation Response: Upon activation, the unit immediately captures an image and simultaneously
activates the audible (buzzer) and visual (LED) warnings.
Scope:
Customer Site Project Managers and Engineers, Wisen Service Engineers, etc.

1. Product Introduction
The WiSen Vision Unit is one of the key products in our patented WisenMeshWAN® and
WISENMESHNET
®
geotechnical safety monitoring system. Working together with Wisen nodes and gateways, it
includes a high-definition 8MP black-light-grade camera with automatic flash, and an LED/buzzer warning system. The
unit is powered by primary batteries or external DC (7-32V) and uses its embedded 2G/3G/4G or WiFi/Ethernet
modules for image transmission.
This product operates using our core technology, i.e., WisenMeshWAN® and WISENMESHNET
®
Low Power, Intelligent,
Wireless Sensor Network protocol. This product satisfies the three fundamental identities of the system:
A. Network Life Span: to maximise battery life across the mesh network as a whole;
B. Network Data Arrival Rate: to minimise data packet loss;
C. Single Node Environmental Coverage: to maximise radio coverage.
Our product has a minimum IP68 rate and is designed to work in a tough environment. It is small in size, reliable in
performance, easy for maintenance, and has strong immunity to radio-interference.

5. Operation Procedures
5.1．WiSen Vision Unit Location Choices
Location: There are two fundamental considerations that are used by Wisen to identify available location for a WiSen
Vision Unit:
1) Firstly, the mesh coverage is the primary factor to be considered. It is vital to arrange the wireless mesh
topology so that all the nodes in the system are connected. The recommended location of a Vision Unit is
next to the gateway, where wireless trigger pings from nodes can always be received;
2) Secondly, 2G/3G/4G coverage (or equivalent when WiFi, Ethernet modules are used) in the site must be
available to ensure communication between a Vision Unit and a remote server. The simplest way to check
the signal availability on site will be to use a mobile phone having the same service operator as that of the
Vision Unit;
3) Camera placement: avoid nearby objects that may reflect flash; avoid facing strong light sources.
5.2．Deployment Procedures
1) Open packaging, take out unit, open lid;
2) Insert 4 x ER34615 batteries (observe polarity);
3) Insert Micro SIM card into 4G daughter board (golden chip facing PCB, cut-corner outward);
Figure. SIM Card Insertion.
Note:
A. SIM Card Installation: To insert/replace the SIM card, you MUST Turn off the power!
B. Push the SIM card all the way into the SIM holder until you hear a click, which means a secured
insertion is made.

www.wisencn.com Page - 10 - of 15
4) Install antennas (mesh and 4G) firmly;
Figure. Mesh Antenna (left) and 2G/3G/4G Antenna (right).
5) Connect external camera:
Orange -> R-; White -> R+; Green -> T-; Blue -> T+; Black -> GND; Red -> VCC
6) Connect LED/Buzzer (if used):
Green -> G; Yellow -> Y; Red -> R; White -> Buzzer; Black -> VCC
7) Connect external DC power if needed (DC_IN and GND terminals);
Warning: incorrect power connection will cause serious damage.
Figure. DC Cable & RS232 Connections.
8) Power on a Vision Unit: observe LED sequence: Red, Yellow, Green flash once each, then warning colour
flashes 3 times with buzzer;
9) On the 4G daughter board, the LED flashing sequence is as shown below:
A. “PWR” (power supply) turns on;
B. “CNT”: slow flashes (meaning searching for a valid network), then quick flashes (meaning registering to
the found network);
C. On the Vision Unit main board, “NET” LED turns to solid green (meaning a successful connection to the
cloud sever was established).

www.wisencn.com Page - 11 - of 15
It overall takes about 30-40s to connect to a server.
Figure. Mesh LED and 4G Daughter Board LEDs.
10) After initial 2 intervals (3min each), unit reverts to configured T;
ONLY if connection to server is available, the 2nd Time Interval takes one photo and sends back to
the server.
11) Tighten lid and cable glands;
12) Validate image data on Wisen Visualisation Platform.
5.3．Mounting Options
Mount unit securely on pole or wall using fixing bracket. Ensure camera has clear view of target area and is not
obstructed.
6. General Maintenance and Notification
1) Once the Vision Unit is installed and working, please do not interfere with it (e.g., moving around, power cycling)
unless it is absolutely necessary;
Wisen Innovation Technical Doc. No.2026 WiSen Vision Unit (TR) - User Manual
www.wisencn.com Page - 12 - of 15
2) The Vision Unit relies on radio signals to communicate with the nodes. It must be wirelessly reachable by the
nodes and please ensure that it is not covered by any materials, which would block the radio signals, for example,
chicken wire, aluminum sheet hoardings, etc.;
3) If no data is received from the Vision Unit, then please carry out investigations in the following two stages:
A. Remote Inspection of historical data, to identify:
a) Whether the heart-beat message has been sent back successfully at each time interval;
b) Whether the voltage in the heart-beat message is as expected, if not, please check the batteries;
c) Whether the signal strength has become significantly weaker, if yes, please check the antenna has been
screwed on firmly;
d) Whether the SIM card contract is valid and that payment is paid up to date.
B. On-site Inspection: if all above are good, please arrange for an on-site inspection to check:
a) Whether the Vision Unit has visible external damage;
b) Please check that the 2G/3G/4G and Mesh antennas have not been screwed to the wrong connectors;
c) Whether the antenna is bent or damaged and it is not blocked by new construction, e.g., hoardings;
d) Whether any live and high voltage cable is directly hanging right next to the Vision Unit 4G antenna; [If
so, remove and keep a minimum 0.5m distance];
e) If an external DC power is used on a Vision Unit, then ensure it is NOT shared with any other heavy
machinery, which will cause a power surge;
f) Whether any connectors are loose.
Notices
:
i. Case One: If any improvement has been made from the list above, please inspect the data from the Wisen
Visualisation Platform;
ii. Case Two: If all the actions from the list above have not cured the problem, please do take high quality photos
during the site inspection and share with the Wisen support team for further consultancy (if needed).
