BulletCam HL 5MP
- CCTV Lens Guide
- Hard Drive Size Guide
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.
Resolution (Megapixels) |
Days of storage provided by 1TB per camera (continuous - full 25 frames per second) |
Days of storage provided by 1TB per 4 cameras (continuous - full 25 frames per second) |
Days of storage provided by 1TB per 4 cameras (50% motion- 15 frames per second) |
---|---|---|---|
1 | 44 | 11 | 36 |
2 | 22 | 5 | 18 |
3 | 17 | 4 | 14 |
4 | 11 | 3 | 9 |
5 | 9 | 2 | 8 |
6 | 8 | 2 | 6 |
8 (4K) | 5 | 1 | 4 |
12 | 4 | 0.5 | 3 |
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.

AI-powered surveillance with hybrid illumination for color clarity
BulletCam HL offers best-in-class motion detection accuracy and intelligent AI-based object recognition. The camera provides high-definition image quality, supports real-time viewing, and raises the bar with hybrid illumination — combining IR and white light to ensure clear footage even in total darkness. Within the Ajax ecosystem, BulletCam HL interacts seamlessly with intrusion protection, fire detection, and automation devices to create an integrated design for safety and comfort — all accessed within a single app. Footage is instantly accessible via mobile, desktop apps, or local VMS, and the end user retains full control.
Full-color visibility, even in the dark
Hybrid illumination in BulletCam HL cameras automatically switches between infrared and white light based on object recognition or motion detection. This ensures high image quality in low-light conditions and at night. The feature provides full-color footage that helps identify clothing, vehicle color, or other critical details. The sudden white light can also act as a deterrent, making intruders aware they have been spotted.
- IR illumination range: up to 50 m
- White light illumination range: up to 50 m
Tailored lens for any scene
Select from a variety of lens options to match your installation needs. Use wide-angle lenses for open areas such as building perimeters, or choose a narrower view for corridors and compact spaces. Higher resolution provides better coverage and detail over extensive areas, while lower resolution is ideal for limited spaces where ultra-high detail is not a priority.
Balanced lighting in every frame
Ajax cameras easily adapt to changing lightning conditions thanks to True WDR. This smart technology, involving hardware and software, corrects uneven lighting in complex scenes, frame by frame, in real time. True WDR provides excellent video quality with clear details and is configured in Ajax apps. The process is simple and allows for instant enhancement in video quality.
Camera empowered by AI
Ajax cameras offer AI-powered object recognition for efficient event recording and storage. Users can configure recording based on their needs, from continuous to triggered by motion or AI detection. The settings help capture critical events, such as a vehicle entering a parking area or a person crossing a restricted zone. This helps to reduce unnecessary footage and makes it easier to review recordings. AI processing takes place directly in the camera, eliminating the need for additional equipment or subscriptions. Both users and security personnel can easily monitor spaces via a smartphone, receiving instant notifications when movement is detected — no specialized security training required.
