The best in the business! Dave is a top bloke and a pleasure to deal with, responsive and always helpful. Had a ground anchor, chain and padlock at my door in a jiffy. The products themselves really are worth the money, their Apex Pro really is the dogs danglies. Would think any potential theif would get a sinking feeling once they see that in the ground!! Could not recommend more, putting some pennies away to hopefully get the crown jewel; their Guardsman Barrier!

The guardsman is a very robust, sturdy and secure security device. A great piece of mind for myself with regards to securing my motorcycle in my garage. Dave, constantly kept in contact to let me know when they would install the guardsman. Fitment was done quickly with no fuss at all.Great service.

Really easy guys to deal with and good piece of kit. Been looking at a barrier for a while but slightly put off by the cost. Saw it being demo'd at a show and took the plunge. Really happy. Very easy install job by their team. Piece of mind now the shed has some protection.

We couldn't be more pleased with our Guardsman, Defenders and Apex Pro ground anchors. The customer service from Image4 Security has been faultless throughout - from our initial inquiry, keeping us up-to-date on progress of our order. The guys arrived to fit our devices exactly on time, did the job brilliantly, were courteous and respectful, cleaned everything up afterwards and took plenty of time to check and explain the configuration. We would have no hesitation in ordering again from Image4 Security.

Excellent installation of two Guardsman Security Barriers. Easy ordering. Good communication. Installed efficiently and no mess. Friendly and approachable. High quality product, which I hope is never tested. Easy to open and close every day. Highly recommended.

Had the pleasure of meeting these guys at the motorcycle live show, ordered a ground anchor with a chain, turned up to fit it, all done in 30 mins, cleaned up, product is great, no chance of anyone taking this bike in my opinion! Highly recommended

I’m very happy with my Guardsman with chain anchor installation, installed outside of my house rather than garage (which I don’t have!) to prevent anyone from easily rolling away with my bike during the night or when I’m out.This isn’t the designed use of the Guardsman and I’m very pleased to say that David and the team were very diligent in checking all details, customising the fitment and completing a very neat install. Used as I have chosen to, the Guardsman makes stealing my bike from my pathway a major challenge - hopefully enough to put off any attempts and certainly enough to make it very challenging indeed.The item is very well designed and made with many anti-theft features - from obstructing the area above the lock to prevent lock drilling to rounding off all the installation bolts so it can’t be loosened.Great and unique product, nothing else in the market is comparable.

My experience of dealing with Image4 Security when I purchased their Guardsman Security Barrier really could not have been better.The purchase process was slick, communication in terms of gathering the information that they required in order to prepare for installation was courteous and the installation itself was efficient and professional.The Guardsman Security Barrier itself is outstanding quality - a really impressive piece of kit which inspires confidence in the security of my garage.HIGHLY recommended!


According to insurance companies, using a disc lock can make your motorbike three times less likely to be stolen. Using a disc lock with a built-in alarm such as our ZOVII ZD10 alarmed disc lock adds that additional layer of security and can put thieves off attempting to steal your bike at the same time as alerting you to the disturbance.

A disc lock is a physical lock that sits on the motorbike brake disc and stops the motorbike wheels from turning and therefore stops your motorbike from being wheeled away. If the disc lock is alarmed, such as our ZOVII ZD10 alarmed disc lock, any disturbance to the lock will trigger the 120dB alarm to be triggered. This can put off the thief and alert you to the disturbance.

The ZOVII ZD10 alarmed disc lock works by using a vibration sensor and 120dB alarm which are triggered when the disc lock is disturbed. This can put the thief off stealing your bike and alert you to the situation.

A disc lock is positioned on a motorbike brake disc and is locked in position using the push locking pin which sits through one of the holes in the brake disc. Once locked into position, the disc lock prevents the wheel of the motorbike from being turned and thus stops your bike from being wheeled away and stolen.

Like all security devices, with the right tools and knowledge, they can eventually be broken into. However, due to the compactness and design of the disc lock gaining access to the locking pin can be extremely challenging and therefore any disc lock is a great first layer of defence when securing your Motorbike. They are also very useful when out and about as they are compact and lightweight and easy to carry.

The discs of the rear motorbike wheels are generally more awkward to remove; for this reason, the disc lock should be used on the rear wheel. To prevent a potential thief from bypassing the disc lock by loosening the brake disc, it is highly recommended that a disc lock is used on each brake disc of your motorbike.

The battery of the ZOVII ZD10 alarmed disc lock lasts between 6-9 months depending on use. The battery used is a lithium CR2 battery available from most supermarkets
