VigilPlus Remote Monitoring System for Heritage Organisations

Key features

Real-time data

Vigil+ sensor readings are in real-time. Knowing the real-time readings of sensors means alarms can be sent immediately for any potentially dangerous changes to the environment.


Perpetual data collection

Unlike traditional ‘data loggers’ or ‘data sampling’, Vigil+ sensor readings are held in perpetuity. Spook understands that importance of providing longer trend data periods to study in order for a more accurate measurement to be applied. Users are able to continually “Measure, Analyse, Improve and Control” by studying long-long-term sensor trend analysis. By understanding patterns in data, predictive models can be deployed.


Easy installation & low cost

Spook understands not every company has an engineer available to set up complicated systems and make sure everything is functioning correctly. Spook’s wireless sensors are simple "plug and play" devices. They arrive pre-configured and have on-board on/off switches making installation extremely easy.

Wireless freedom

Vigil+ sensors are truly are wireless. In order for sensors to be as efficient as possible, users need to be able to place them anywhere and not worry about power supply. This "plug and play" mentality is going to be what ultimately drives the Internet of Things (IoT) industry forward.

Eventually, when electricity can be transmitted wirelessly over long distances, organisations will be able to place extremely powerful sensors in any location and not have to worry about power issues at all. Until that happens however, Vigil+ wireless sensors are robust and have an approximate lifecycle of 10 years. Spook even monitors the signal and battery level of each sensor making the battery replacement program intuitive and easy.

Calibration certificates

All Vigil+ sensors have been tested by professionals to make sure they perform under a variety of harsh conditions. The readings taken by sensors cannot be altered once the data is recorded. Sensors can be ordered with traceable calibration certificates such as NIST or EN12830. All data is logged and time-stamped under the history tab in Vigil+ for that specific sensor.

Vigil+ wireless sensors are able to communicate with a gateway 250-300 ft. non-line of sight. Expectations for data transfer through 7-10 walls can easily be achieved. By using radio frequencies, Vigil+ sensors and gateways will not interfere with current existing networks such as Wi-Fi. These products are a complete wireless solution geared towards maximum ease of use.

All Vigil+ sensors, gateways and software work seamlessly together to provide complete peace of mind. Customer secure real-time dashboards are available on any internet enabled device.

Departmental and regional access

Spook's customers range from single room installations to multiple room locations across national/international borders.

When multi-room or multi-territory monitoring is required sometimes an organisation may only need to know what is happening under their jurisdiction or in their region or district. Whereas the global custodians may need an enterprise centric view across all regions and territories.

Even at local level there may be a need for different departments to be responsible for their own monitoring footprint. For example, water ingress monitoring may be the remit of the facilities department whereas the temperature and relative humidity of an exhibit may be the responsibility of the conservationist team.

Vigil+ provides multiple dashboard portals to cater for this whilst ensuring management has a global view of everything. Customer can have as many dashboards, users or alarm processes as they want within the simple annual monitoring fee. There are no hidden charges.

Transport and logistics

Museums and Art Galleries are now lending more of their collections than at any other point in their history. There are many reasons members of the public may not be able to visit the main exhibition locations so making collections mobile is the natural extension of sharing art with the public. Enabling more people than ever before to encounter the wide range of material and culture that heritage organisations has in its care comes with its own sets of difficulties .

Often the preparation for such journeys begins months or even years in advance. Whether the exhibition is to be held in a counter museum on the other side of the world or in a temporary exhibition space in the UK means the logistics behind transporting fragile objects requires careful planning.

Before leaving the confines of the parent organisation all objects must be assessed by conservators to see whether or not they are stable enough to travel. If objects are particularly fragile decisions need to be made on what needs to be done in order to transport them safely.

Key areas for consideration are security, environmental threats and knowing exactly where consignments are in real time.

Occasionally certain kinds of objects, for instance delicate ivories, artefacts, fabrics and paintings; will require special conservation materials to be included in order to maintain steady environmental conditions whilst in transit and while being displayed at the temporary location.

Spook has designed a mobile monitoring solution precisely for this called The TRIG (Transportable RIG).

Heritage organisations vary but they share environmental monitoring concerns

Water ingress

Water ingress has the ability to cause damage in a matter of seconds. Installing water/fluid sensors in areas that have an increased likelihood to cause water leaks or floods is vital.

Heat extraction

Heating, Ventilation & Air Conditioning (HVAC) or Air Conditioning (AC) equipment together with chilled water being pumped into and out of the facility is the primary heat extraction medium.

Water accumulating on the floor or water dripping from overhead piping can and does cause immeasurable damage. Early detection of any water leakage is a crucial tool in protecting damage to artefacts. Reaction to a water alert can get the maintenance team on the scene in time to deal with the issue and take remedial action long before the incident causes problems.

Natural flood

Equally worrying is natural flood. We live in an era whereby unusual weather patterns can quickly cause flash floods. It is easy for a flash downpour to cause local flooding or entrapment of water in ducts and guttering around buildings.

Spook has an array of wireless water sensors designed for detecting water ingress immediately.

Light (LUX - luminescence/unit area)

Galleries and viewing areas are often lit to set the appropriate mood, there are usually special requirements to insure images, pictures and fabrics remain pristine. Wireless light meters are a perfect solution to track LUX to help avoid accidental lighting mistakes.

Light needs to be managed, whether it is with automatic dimmers or by the more conventional method of staff entering an area to close blinds to prevent sun damage.

Seasonal light patterns

Because Vigil+ retains sensor readings in perpetuity, reports can be produced to study long-term trend data. Analysis can be gained to predict light patterns at different times of day, season or even year. By understanding the cyclical changes to light means planning and building ‘LUX’ routines is achievable.

LUX hours

Many heritage organisations have areas that are sensitive to light. Sometimes they have a specified "Light Budget." Vigil+ wireless light sensors are ideal for tracking and managing "Lux Hours”.

Temperature & humidity

Relative Humidity (RH)

The Association of Independent Museums (AIM), recommends RH to be maintained as closely as possible within a 20% variance. This allows for daily and annual seasonal changes to be taken into account.

Commonly used bands are 40%-60% or 45%-65%. However, acceptable levels may vary depending on what is achievable locally and that which best suits the needs of the particular items in the heritage collections. Daily RH fluctuations tend to be more damaging than constant levels. Even seasonal changes can have a detrimental effect.


AIM highlights the importance of maintaining stable temperatures. As with RH, fluctuating temperatures cause greater damage to the collections than achieving a constant level.

Heritage organisations exhibition spaces are generally heated to accommodate members of the public and a typical temperature range for human comfort levels is around 17-21°C. However, storage of items can be kept at lower temperatures to slow down degradation.


Heritage organisations often tread the fine line between public enjoyment and protection of valuable assets. Grade II listed buildings, exhibition spaces and areas with delicate fabrics and wall coverings all need to manage the difficult balance between members of the public viewing them and the organisation conserving them providing adequate protection.

Activity sensors

For important or irreplaceable items a small activity detection sensor is available. This wireless sensor can be used to determine if an asset (art-work) is removed from the premises, or just moved in general. Any vibration or sudden movement would cause an alarm.

Infrared (IR) sensors

IR sensors are designed to locate movement even in completely dark environments, perfect for additional after-hours security.

Boundary/pressure pad sensors

These sensors are ideal for areas that need to allow viewing platforms or areas to members of the public and to protect ‘no go’ boundaries. Often these areas are simply protected with a perimeter rope and exhibition security staff are employed to ensure no one intrudes beyond the permitted area.

By installing IR beams and pressure pads, any vulnerable area can be monitored with ease. Subtle alerts can be discretely sent to security staff within the vicinity. This ensures public viewing of exhibits remain calm and members of the public are not unduly panicked while enjoying their visit.
