SiteGuard Tower: Portable Solar Powered Wireless Intrusion Alarm System
- 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)

Featuring MotionCam Outdoor (PhOD) Jeweller on each side, SiteGuard tower provides 360-degree coverage at a distance of up to 30 m and photo verification of the alarms in 9 seconds. Also, a user can request a real-time image for situational awareness via Ajax apps. Upon intrusion detection, StreetSiren Jeweller activates the sound of 113 dB and LED flashing lights for up to 3 minutes, alerting intruders that their presence is known.
Hub 2 (2G) Jeweller or Hub 2 Plus Jeweller control panel ensures a user instantly receives informative push notifications about alerts via Ajax apps. The hub also allows remote management, battery health monitoring, and automation scenarios execution to arm/disarm the system according to the site’s operation hours. With the help of 12-24V PSU for Hub 2/ReX 2 power supply unit, the control panel is connected to an external battery, which is charged by a solar panel. For indoors usage or proper storage, SiteGuard tower is equipped with a socket.
The hub and PSU are safely hidden in a weather-resistant IP-rated box and protected with DoorProtect Plus Jeweller. Thanks to tilt and shock sensors, the device detects and alerts a user about an attempt to open the box, unauthorized movement, and interference with SiteGuard tower. In addition, thanks to its anti-masking technology, MotionCam Outdoor (PhOD) Jeweller alerts about accidental or malicious actions aimed at blocking its sensors even if the system is disarmed.
