7" Split-Screen Bracket to Windscreen Quad AHD Mirror Monitor | MON293BQAHD
4 Channel Split Screen Mirror Monitor for Blindspot, Rear View, and Reversing Camera. Up to 4x1080P AHD inputs. IPS 1024x600 colourful, bright, clear display. Multiple split modes. Bracket direct to windscreen model, see our bracket options tab for more details when choosing a bracket.
About our 4 Channel Quad Mirror Monitor Display for 1080P AHD Reversing Camera / Side Blindspot Cameras / Rear View Camera
High Definition Image Quality - Our 7 inch mirror monitor display uses a 1024x600 IPS panel. IPS panels are used on gaming PC monitors to produce even better colours, a sharp defined image and great viewing angle. This produces an amazing, easy to view image.
Multiple Input types up to 1080P - This monitor can accept up to 4x reversing/side/rear view camera signals including the latest AHD signal, whether it is 720P/960P/1080P in PAL or NTSC format. The monitor can also accept traditional standard definition signals (CVBS), however we recommend AHD for the best experience.
Multiple Split Image Modes - This monitor allows Full Screen on One Channel, Two Way Splits, Three Way Splits and 2x 4 Way Splits (4 Square/H split)
4 Channels for Reverse, Rear View, Side View Cameras - The monitor wiring harness is fitted with 2x 4 pin aviation connectors. This gives space for a rear view, and reversing camera to be fitted. Change between channels by either using the V1/V2 button on the screen, the remote control, or the trigger wires.
Most Popular Location for Fitting a Monitor - The position of the interior mirror is where we naturally look when we wish to see what is behind us.
Trigger Wires for automatic channel changing e.g. reversing/indicating - Optional to connect. This 4 channel mirror monitor has 4 trigger wires, which can be used to automatically change channel when events occur e.g. reverse gear. Trigger delay time allows you to hook up to side indicator lights and set a time delay to avoid the monitor just flashing on/off the channel when the indicator light flashes e.g. change delay to 3/4 seconds, which is longer than the flash interval of your indicators and it will stay on that channel for 3/4 seconds since the last time your indicator light flashes.
Full Function Remote Control - We provide a remote control that allows you access to all the menu functions and changing channels from a distance. These functions can also be achieved on the monitor by using the buttons.
Two Year Guarantee and Lifetime Support - This monitor should last a very long time without any issue. We guarantee it to be free from faults for two years. After two years we are able to offer low cost repairs to keep your system in good condition and avoid extra time or expense installing all new components. We also keep good stock of spare parts such as wiring harnesses should you decide to take the monitor out of the vehicle with you when you sell your vehicle but leave the wiring where it is.
Fits our range of windscreen swan neck bracket attachments - We stock a range of brackets to fit the most commonly found windscreen mounting plates fitted to vans. To order a discounted bracket with the monitor, please view our bracket options tab, then select your desired option from the drop down menu before adding to basket.
4 Pin Channel Inputs - This monitor is fitted with 4x 4 pin inputs. This is the favourite connector type for the reversing camera industry allowing the monitor to power the cameras - avoiding CANBUS issues and allowing for an easy install.
Check out our video below showing the function, wiring, and menu system of the split screen mirror monitor.
Rear View Mirror Mount Options Details
We have various mounting options for the rear-view mirror reversing camera kits. Please see the options below. Remember to carefully check the description and photos, as some mounts look similar. We only stock the most common vehicle mounts (usually vans). Be aware that if there is a plastic cover over the mounting plate this may not fit back on with a bracket in place.
Clip-over Existing Mirror - This is the most popular option, especially if you already have an interior mirror to clip on to. This option has a version of the mirror monitor that has strong spring loaded clamps to attach it to the old mirror.
ACCMB1 - Mercedes Sprinter with Auto Lights / Wipers Option - We usually see this type of mounting on Mercedes Sprinter vans that are fitted with auto lights or wipers. 90 degree twist (clockwise from 9 o'clock position to fit).
ACCMB2 - Some Ford / Universal - Most commonly seen on Ford vehicles e.g. Ford Transit. Also known as the universal bracket because the mounting plate (button) that works with this bracket is the easiest to glue on. We stock the button and glue kit (see further down). Slides down from above.
ACCMB3 - Some Volkswagen - We usually see this mounted to Transporter, various cars, and Crafter vans built after 2017. 90 degree twist (clockwise from 9 o'clock position to fit).
ACCMB5 - Some Mercedes / Renault / Vauxhall - Most commonly found on Mercedes Sprinters without auto lights/wipers, as well as older Renault Trafic, Renault Master and Vauxhall Vivaro vans. Mounts by sliding down from above.
ACCMB6 - Universal Ceiling Mount - Allows you to attach the monitor to the ceiling.
ACCMB7 - Some Citroen Relay / Peugeot Boxer / Fiat Ducato / Iveco Daily Vans - We typically see this fitted to earlier models of Relay/Boxer/Ducato vans, as well as recent Iveco Daily vans. Slide down from above fitment.
ACCMB8 - Some Renault Master, Vauxhall Movano and Nissan NV400 Vans - We typically see this fitted to earlier models of Renault Master, Vauxhall Movano, and Nissan NV400 vans. Slide up from below fitment.
ACCMB2 + MP35 - Some Citroen Relay / Peugeot Boxer / Fiat Ducato / Ford Transit / New Vauxhall Vivaro - Most commonly found on more recent Ducato/Relay/Boxer vans. Usually this will be hidden by a round plastic circular cover. There will also be a spring underneath the cover that will need to be twisted anti-clockwise to remove (be careful in case it pings off in the direction of your eyes).
ACCMB2 + Button + Glue - Universal - adds a button with Loctite 319 interior mirror adhesive for ACCMB2 bracket to attach to - This is ideal if you find your vehicle doesn't have any mounting plate fitted, or has one that we have no bracket to fit to. This bundle will provide you with a universal bracket, a universal button/mounting plate, and the Loctite 319 interior mirror adhesive required to fix this to the windscreen. We provide full detailed instructions on how to achieve a good, strong bond.
You can now choose to upgrade your kit to the latest AHD technology. This upgrades both camera, and monitor spec. Read more about the technology below.
What is the difference between traditional reversing cameras, and the latest AHD reversing cameras?
For many years reversing cameras have used a technology called CVBS (composite video baseband signal). This is the same technology that you will have seen in the past on devices such as DVD players. CVBS has limitations as to the resolution that it can transmit, typically this is around 480i.
For years, the world has come to see ever increasingly high-definition cameras get developed. Until recently we haven’t seen this trickle down to things like reversing cameras.
The reason for this delay is due to the problems in transmitting high-definition video across distances greater than a few meters. Digital video signal cables are limited to short distances without the use of repeaters. For example, HDMI cable has not long advanced to be able to handle around 15ft before signal degradation becomes an issue.
AHD is known as Analogue High Definition; it allows a High-Definition video signal to travel through a traditional analogue coax cable. This new technology solves the transmission distance limitations issue and allows the reversing camera world to finally experience a substantial increase in both definition and dynamic range.
With it being a new technology, how can I be assured I won’t experience any teething problems?
The truth is that AHD has been around for a number of years now, and it DID have teething problems. This is why we only brought in our range in early 2022, once we were convinced it was stable enough.
We did bring some small batches of AHD kits a few years earlier, selling them cheaply to assess how they performed in the real world. For the most part they worked well, but they weren’t perfect. The biggest problem was something the factories termed “flicker”. In 2021 we were informed that this had finally been solved, and all of our samples / road tests confirmed this.
So are all AHD cameras better than the traditional cameras?
The short answer is no.
As always, the answer is more complex than just comparing numbers. For example, you can get 720P/960P/1080P camera chipsets for just a few quid (£). The cheap camera chipset will give you a worse picture than a good quality traditional CVBS 480i camera, despite its “bigger numbers”.
The only real way we were able to decide on which image sensors we would stock in our new range, was to test them out in the real world with lots of samples.
If the monitors aren’t also 1080P, then what is the point in using a 1080P camera?
Resolution isn’t a massive problem when it comes to the smaller screens used in reversing camera monitors eg 7 inch. The 800x480 (384,000 pixels) digital hi resolution panels used on our standard premium systems have pixels so small it is hard to see them, even close up! The only time we hear people mention resolution as a problem, is when discussing the cheaper analogue LCD panels that have 480x234 pixels (112,320 pixels) displays - these you can easily see pixels.
Our AHD monitors are upgraded to 1024x600 pixels (614,400 pixels), which is a 60% increase compared to the digital LCD. They also use IPS panels instead of standard LCD, which allows for better colour replication.
During testing we notice that some of the best AHD camera image sensors are 1080P only, such as the Sony IMX307 sensor. When you compare this sensor to cheaper 720P/960P/1080P AHD sensors, you see a big difference in night-time picture, as well as when there are differences in light levels across the picture eg. bright headlamps in an unlit area, or shadowy areas on a bright day.
So although you won’t experience full 1080P, when it comes to screen sizes that are substantially smaller than your TV at home, and a lot closer to your eyes, it isn’t really noticeable. Plus you get the main benefits of high dynamic range, great colour, and great low light level performance.
So are there any drawbacks to AHD?
Not many, the main one is the delay in changing channel – this is around 2-3 seconds on average, compared to approx. 1 second with traditional CVBS signal systems.
The second is that the night mode kicks in more suddenly. With traditional CVBS cameras the transition between night and day is much slower. AHD goes black and white as soon as the light level reaches a certain Lux level. Most of our AHD cameras this happens at between 1 and 8 Lux depending on camera model. In night mode the camera image will be black and white, with no colour visible. This has advantages though, since the black and white image will be miles more detailed than a colour image with a lot of “noise” to the picture.
Lastly, AHD isn't recommended for trailers due to the fact that the more coils and links you add to the cabling, the more this will affect the very high frequency signal of the 1080P cameras.
Is there any point in selling the CVBS technology still?
Absolutely, CVBS reversing cameras will still be around for many years to come.
When it comes to car stereos, there are only a few models that can support AHD, the vast majority will only support CVBS.
When it comes to full systems, people will appreciate the cheaper cost, the quicker start up/changeover times, and still appreciate the good image quality that our premium CVBS sensors give.
Our summary
As you can see, things are never as simple as they first appear. All we can ask, is that you trust our judgement when it comes to image sensor choice/quality. Leave it to us to road test hundreds of variations, both day and night, before bringing the best to market (working with the factories to improve their product with our experience).
I hope this bit of knowledge has helped inform your product choice.
