The roadside unit should be ideally mounted at a height of between 2.2m and 3m, although it can be as high as 4m. See our installation section for details.

The units should last several years, dependent on environmental factors. In some environmental situations the specialist internal battery may need replacing, however the unit can be returned for overhaul at modest cost should this be required.

Individuals can buy a gift voucher on the website and forward this to their CSW coordinator. The coordinator can then use the gift vouchers received for all, or part, payment during the check-out.

The roadside unit is supplied with a medium fixing band suitable for a standard sign post (75mm - 120mm), a wrench and a security bit to fix band.

Any community or organisation that is concerned about speeding traffic in a restricted speed zone. It can be used to supplement the work of an existing Community Speedwatch team, or can be helpful to set one up.

Not yet .....Our first model of roadside unit has daylight hours operation only, just as with traditional CSW. This is so that we don't need to use any distracting camera flashes and so that the unit can be smaller, cheaper and lower power. Most of the impact of speeding within communities is during daylight hours, so we've concentrated on that. It'll still work longer hours and more consistently than a team of people at the roadside!

HOWEVER.... we do have a version in development that can be configured to also work at night. Let us know if you're interested and we'll increase the priority for production release.

The roadside unit has been built to be small and discreet. It's about the size of a book ; 200mm x 175mm x 63mm. The solar cell used to power the unit is incorporated in the top of the Roadside unit, so there's no separate power installation or wires to the unit. Easy!

Your community speed watch coordinator can change the speed at which vehicles will trigger the Road Unit camera. There needs to be a significant margin between the zone speed and the minimum trigger speed.

The roadside unit has been designed to look after itself as best it can. Depending on traffic dirt, etc, you may have to wipe clean the camera window and polish the solar cell occasionally to keep it in tip-top condition. We provide user maintenance tips as a download when you purchase the unit.

For orders above £245 and within the UK mainland, yes, postage is included. For everything else there is a variable charge depending on the service and destination. Delivery charges are detailed during the checkout process.

There are ongoing costs per Roadside Unit to maintain the data connectivity and server access. This is necessary as each unit sends data across the mobile network for which there is a direct cost to us, in the same way that there's an ongoing cost for a data service on a smartphone. However, we try to keep that subscription cost as low as we can. The first 12 months are included within the Roadside Unit purchase price, so there's nothing extra to pay for the first year. After 12 months you'll need to start paying for a data plan to keep the unit connected and maintain access to the data it provides. We considered simply having a Roadside Unit cost and bundling the cost of data into it for a longer period, but we concluded this was a fairer way to do it.

If the roadside unit is to be installed on private land then seek the landowners permission, otherwise obtain approval from your local parish council and/or the highways authority in your area. Depending on the installation position, you may need to have Chapter 8 competencies to ensure the safety of you and others during the installation.

According to the police, speed camera warning signs are not required.

However, this is not entirely consistent with the Protection of Freedoms Act (PoFA 2012) and it may be that you will need to have signage for the roadside unit as it contains a public facing camera and therefore falls within the PoFA definition of "Surveillance Camera". According to the guidelines, camera surveillance in public requires signage (and that is only fair given its prolific use when recording and monitoring law-abiding citizens; AutoSpeedWatch only records where offences have occurred).

On our understanding of UK Law we recommend you use our information signs, even though an image is only captured, and the LPD assistant tool used, only after a speed offence is detected. As always, we suggest it's worth involving the local police authority, local councils and highways agency from the start.

It helps identify speeding vehicles, in a similar fashion to traditional Community Speedwatch. If you need information on volumes of traffic against time-of-day, or percentile speed, then a traffic logging product will more likely suit your need. The unit is solar powered, and therefore on dull or overcast winter days it may need to pause to save power and recharge. This means that total vehicle volume counts would be interrupted. Even though the unit might pause like this, it'll still work a lot more consistently than even the most dedicated team of CSW members roadside, and therefore identify vehicles that persistently speed. If you're particularly interested in vehicle volume counts then use a vehicle logging device instead.

AutoSpeedWatch only needs to record data relating to the offending vehicle, and no personal information relating to the driver or vehicle occupants. Taking a picture of the rear of the vehicle helps us achieve this.
