- 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, frame rate settings, and whether you have H.265 encoding enabled or not to save space (We advise turning it on to double the capacity shown below with ease).
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 (to perhaps double or more these figures again).

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 2 Terabytes for a 4 x 4/5MP HD camera setup, as this should give you approx 2 weeks using H.265 @ 20fps and that is on continuous, not motion-detected recording.
(You may only require the full 25 frames per second on certain cameras if things are fast-moving - ie above a till)

Ajax Hub2 (4G)
Security system control panel with support for photo verification & LTE cellular module
Spare accessories available (likely on a special order basis), if required please speak to Sales or your BDM.
In control of security, not your private life
Hub 2 manages all the Ajax devices in the system to alert users about open doors, broken windows, threats of fire and flooding. If burglars break into your facility, Hub 2 will notify the monitoring station 1and send photos from the MotionCam detectors. You won’t need to live under the constant supervision of the security cameras to know what’s going on.
Alarm photo verification in 9 seconds
Hub 2 works with MotionCam and MotionCam Outdoor motion detectors. When detectors are triggered, they take a series of photos. It helps to evaluate the situation at the facility. Visual verification helps you instantly assess the situation, relieving users of unnecessary anxiety, and security companies — from false calls of patrols.
Always connected — via cable and cellular networks
Communication with the outside world is critical for the security system control panel. Its reliability and stability guarantee timely alarm transmission to the security company and users.
Hub 2 can be simultaneously connected to three Internet service providers — via Ethernet cable and 2G, 3G, and LTE 2 cellular networks. The automatic switching between channels takes seconds.
Guaranteed delivery of alarms and visual alarm verifications
To ensure reliable communications, we have equipped Hub 2 with four antennas and support of two proprietary radio protocols: Jeweller and Wings. Jeweller is responsible for the transmission of commands, events, and alarms, while Wings provides batch transmission of images. Ajax two-way radio communication uses frames to synchronize device communication sessions, authentication to prevent fraud, and encryption to protect against data theft.
Flexibility at the core
The Hub 2 radio network covers several floors and separate buildings — thanks to the communication range of 2,000 meters and the ability to connect five range extenders. To manage access and security zoning of the facility, the hub allows connecting 50 users and creating 9 security groups. Hub 2 is a perfect choice for home and business security.
Controlled with apps
We refrained from control buttons on the control panel body and archaic interfaces — apps are more convenient and reliable. They connect to a hub via a secure channel through the Ajax Cloud server located in several AWS data centres. Server availability in 2021 was 99.995%.
Apps allow system users with administrator rights to manage the security of the facility, change settings of the hub and the devices connected to it, create scenarios, and monitor events. From a smartphone or a PC. On the site and remotely.
Automates security
Hub 2 allows creating 32 scenarios and minimizing the impact of human factor on security. The hub can arm and disarm a facility or a group by schedule. Instantly activate a smoke machine if someone enters the premises. Blackout the premises and turn on emergency lighting in case of fire. Or shut off the water in case of a leak. Control lights, electric locks, roller shutters, and garage doors — by arming/disarming, button press, or a detector alarm.
Resistant to sabotage
Whatever happens to Hub 2, the security company and the users will be notified. No one can disconnect the hub unnoticed when the facility is disarmed. If an intruder attempts to dismount the device, this will trigger the tamper immediately. The Ajax Cloud server can notify about the loss of connection with the hub in 60 seconds due to frequent polling. Even if the building is de-energized, the hub will protect the object for up to 16 hours with a built-in backup battery.
Future-proof
Hub 2 runs OS Malevich — a real-time operating system developed by Ajax Systems. OS Malevich is extremely stable, immune to viruses, and protected from cyberattacks. Modular architecture simplifies the constant upgrading of OS Malevich.
Hub receives new features several times a year with over-the-air updates. The update process is automatic and takes minutes when the security system is disarmed. The hardware configuration will allow Hub 2 to evolve and remain relevant for years to come.
Hassle-free installation
Hub 2 is ready to operate out of the box. All communication modules, power supply, and backup battery are already installed. To start setting up the system, you need to connect the device to the power supply and the Internet, insert the SIM cards, and scan the QR code through the app. With the SmartBracket mounting panel, there is no need to disassemble the device body during installation.
Connecting security devices, video cameras, users, testing the radio signal, creating groups and scenarios, even sending a request for connection to the CMS — all system settings are always available in the Ajax apps. Whether you are at the site or not.
Easy security system upgrade
To simplify updating hubs at the facilities, we have provided the ability to transfer data between them automatically. The import feature allows you to transfer settings, connected devices, groups, scenarios, and users from the old hub to Hub 2. In less than 15 minutes.
