Nice L9BAR-KIT Automatic Barrier Gate System (24V DC) for Up to 9m Boom Arm
Unless selecting a vari-focal camera (with an adjustable lens) It is important to select the correct camera lens option for where the camera is to be positioned. A smaller lens will give you a wider angle but will be "zoomed out more", while a bigger lens will narrow the angle down and "zoom in more". See below to give you some idea on angles of Megapixel HD Cameras:
| Lens in mm | Approx Viewing Angle (degrees) | Ideal Distance (metres) | Typical usage/notes |
|---|---|---|---|
| 2.8 | 106 | <6 | For seeing as much of the immediate area as possible such as above a doorway/low down/garage soffits (edges can appear slightly warped/distorted) - clearly "zoomed out" |
| 3.6/4 | 83-90 | <12 | A great general purpose option giving great coverage still in the corner of a room or higher up on second floor soffits with less distortion - more of a natural "zoom" |
| 6 | 56 | 6-20 | Narrows down the angle and zooms in to look past the immediate area a little to gain more detail - down a driveway for example from higher up |
| 12 | 24 | 20+ | Zooms in significantly more to look at a gate, entrance or adjascent building |
| 16 | 19 | 24+ | As above but more so |
The amount of hard drive space you require is dictated by how many cameras, as well as their resolution and frame rate settings. Finally you can often make your storage space last a lot longer by enabling motion detected recording rather than continuous, especially if there are long periods of no activity.

As a rule of thumb we recommend a minimum of 2 Terabytes per 4 x 2-4MP HD cameras, as this should give you 2 weeks to a month with a few adjustments on motion detected recording. You may only require the full 25 frames per second on certain cameras if things are fast moving.

Nice L9BAR-KIT Automatic Barrier Gate System (24V DC) for Up to 9m Boom Arm
The Nice L9BAR-KIT is a premium long-reach automatic barrier system designed for large vehicle entrances where maximum clearance and reliability are required. It is commonly used in industrial sites, commercial parking areas, logistics hubs, and high-security access points. The system operates with a 24V DC electromechanical gearmotor integrated into a steel barrier housing. The control unit is located in the upper section for easy access and simplified maintenance. It allows quick programming of parameters such as speed, force, and automatic closing time through a display-based interface. The L9BAR supports boom arms up to 9 meters, making it one of the widest barrier solutions in the NICE range. Despite the long arm, it maintains controlled and stable movement with an opening time of approximately 8–12 seconds, depending on installation and configuration. The system is designed for intensive-duty operation (up to ~150 cycles/hour) and includes a high-strength balancing spring system rated for long operational life (up to 1,000,000+ cycles). Its elliptical boom design improves wind resistance and structural stability.
