Solid State
The 4K DV4 has no moving parts which makes it more reliable than camcorders or hard drive recorders when subjected to shocks or vibrations. Excessive movement suffered by mechanical devices can lead to a recording being lost or could even cause damage to unit itself.



Our cameras connect to the DV4 via the av-in socket. There is a choice of 4 recording resolutions including:

DVD Resolution: 720X576. Recording time:45 mins per 1GB

Web Resolution: 320X240. Recording time: 2 hours per 1GB

DVD resolution is great for quality recordings that you want to play back on a large TV screen or burn later onto DVD. The Web Resolution setting is ideal for use on your website or uploading the video to YouTube.



Activating the Recording

The DV4 has three methods of activation (power on/off and start/stop video recording):

Recorder activation


using the buttons on the DVR itself.

Remote activation


using the wired remote control.

PowerStart activation




automatic startup and record controlled by your vehicles ignition system.

In order to use the PowerStart activation facility on the DV4 you will need a 12v Connector to wire into your car/bike electrics and the DV4 5v adapter. Alternatively if you have a cigar power socket on the vehicle you can get our Car Cigar Adapter.


Using one of these adapters when the DV4 is in PowerStart mode will mean the DV4 starts up and begins recording automatically as soon as it receives a live power feed. When the power feed is turned off the DV4 will stop recording and shut down. Use of a power adapter will also allow you to charge the DVR on the move and therefore record indefinitely.




Video is recorded at a high frame rate of up to 30fps and is saved into the recorders memory. This memory is also expandable with extra high speed memory cards should you wish to record for longer.


The built in colour monitor (2 x 1.5 inch) makes the 4Kam easy to set up as you can see what the camera sees. Being small enough to fit inside a packet of cigarettes (78 X 55 X 20mm) and extremely light (80g), the DV4 can easily be slipped into your pocket or bag.
