Xignal M720(G4F)-IP Hybrid Mobile NVR
The networked hybrid. Four analogue cameras plus four IP cameras on one recorder, five to eight channels in total, with a built-in switch and ONVIF support so the IP side is wired and configured without a separate network box. It also carries plate recognition and the ADAS and DSM driver AI options.
Supplied, fitted and commissioned
Overview
What the M720(G4F)-IP does
The smaller of the two hybrid recorders, and the more networked one. Four analogue inputs take AHD, TVI or CVI cameras over cabling already on the vehicle, and four IP channels carry network cameras, for five to eight channels in total. What sets it apart is that the IP side is handled on the box: a built-in switch means the cameras plug into the recorder rather than into a separate network switch, and ONVIF support means the cameras do not have to come from one manufacturer.
It also carries the driver AI that the larger hybrid does not. ADAS connects a forward facing camera for lane and collision warnings, DSM connects a cabin facing camera that detects fatigue, distraction, smoking and phone use, and the recorder reads plate licence numbers. With a 4TB drive and eight channel playback, the trade against the M728(G4F)-IP is channel count rather than capability: that model takes eight analogue inputs and adds a heated drive bay, but publishes no switch, no ONVIF and no driver AI.
Where it fits best
- Patrol cars, vans and light vehicles moving to IP cameras without a separate network switch
- Mixed installations where the IP cameras come from more than one manufacturer
- Fleets that want lane departure, collision and driver fatigue warnings on the same recorder
- Operators needing plate recognition alongside ordinary recording
- Vehicles where four analogue views and a few network cameras is the whole requirement

Figures published by the manufacturer. One thing worth knowing about the source: its specification table covers this model and the larger M728(G4F)-IP together, and several rows carry two values. The figures published here are this model's, taken from the first of each pair, which the manufacturer's own feature list labels by series. Note also that the analogue inputs take AHD, TVI or CVI but not CVBS, where the M728(G4F)-IP does list CVBS. Where a figure reads Not published, the manufacturer does not state it, which is not the same as the feature being absent.

Questions
Before you specify the M720(G4F)-IP
Questions we are asked about this model.
Which of the two hybrids should I specify?
Channel count decides it first: this model takes four analogue cameras, the M728(G4F)-IP takes eight, and both add up to four IP channels. After that the two diverge in what the manufacturer publishes for each. This one publishes a built-in switch, ONVIF support, Wi-Fi, ADAS, DSM, plate recognition and a 4TB drive. The M728(G4F)-IP publishes none of those, and instead publishes a heated drive bay, a longer eight to ten second power-loss hold and a pre-allocated file system, on a 2TB drive. So it is roughly networking and driver AI here against channel count and ruggedness there, not simply a bigger and a smaller version of one product.
What do the built-in switch and ONVIF actually buy me?
The switch means the IP cameras plug into the recorder itself rather than into a separate network switch mounted somewhere else on the vehicle. That is one less box to find space and power for, one less thing to fail, and a simpler loom. ONVIF is the open protocol that lets a recorder talk to IP cameras from different manufacturers, so you are not tied to one camera brand for the life of the vehicle and can replace a failed camera with whatever is available. Neither is published for the M728(G4F)-IP, which is the single clearest reason to choose this model over it.
Does it take my existing CVBS cameras?
No, and this is the one place the smaller hybrid is more restrictive than its siblings. The analogue inputs take AHD, TVI or CVI. CVBS, the older composite standard, is not listed for this model, though it is listed for the M728(G4F)-IP and the analogue M710(G4F). If a vehicle still runs CVBS cameras, either those cameras get replaced or a different recorder is specified. Tell us what is fitted and we will check it before you order.
Is this the answer to an all-IP school bus requirement?
No, and neither hybrid is. Where an authority requires IP cameras for school transport, the requirement is typically seven cameras, four exterior and three interior. This recorder carries four IP channels and the M728(G4F)-IP carries four as well, so neither reaches seven on the IP side. Where the hybrids do fit is the mixed case, a vehicle part way through moving to IP. If the contract is regulated school transport, say so on the enquiry and we will specify against that rule rather than around it.
What do ADAS and DSM do on this recorder?
They are separate camera modules specified at order, not features of the box. ADAS faces forward and gives real time warnings on lane departure and collision risk. DSM faces the driver and detects fatigue, distraction, smoking and phone use. The recorder also reads plate licence numbers. Each camera module occupies a channel, so count them against the four analogue inputs when you plan the views a vehicle needs.
Where do the days of retention actually live?
On the drive in the vehicle first, and on the server after that. The 4TB drive is a rolling buffer sized to the route and the channel count, which on eight channels of 1080p is a real constraint. Longer retention lives on the server the footage is offloaded to. Three routes run alongside each other: reduced rate streaming over 4G while the vehicle is moving, full resolution transfer over Wi-Fi at the depot, and manual extraction of the drive or the SD card when an incident needs the original file.

fleet and school transport rules
The M720(G4F)-IP Against Common Requirements
The hybrids get asked about wherever an authority requires IP cameras for school transport, so the honest answer belongs at the top. Four IP channels does not cover a seven camera all-IP bus, and no configuration of this model will. What follows is what each rule asks, and where this recorder does and does not answer it.
- Seven cameras on a school bus: four exterior and three interior. Eight total channels covers seven in a mixed installation, but not as seven IP cameras.
- Where IP cameras are mandated: this recorder carries four IP channels, so it suits a mixed fleet rather than an all-IP bus. Ask us before specifying it for one.
- Open camera choice: ONVIF support means the IP cameras are not tied to one manufacturer, which matters on a framework that runs for years.
- At least 60 days of retention: the vehicle holds a rolling buffer. Retention beyond what the 4TB drive holds is sized on the server, not on the recorder.
- GPS from an approved provider: the built-in GPS and BeiDou module reports position, and the link to the approved provider is configured at commissioning.
- Telematics on heavy vehicles: many authorities require driving hours, harsh braking, acceleration and speeding to be reported on heavier vehicles, and licensing can depend on it.
- Encrypted storage and an authorised user register: where footage documents a violation, the evidence rules that apply govern the server it lands on rather than the recorder itself.
