What to know about the Safire Smart Dual IP Thermal Camera.
In this article, we focus on the SF-IPTB256A-7D5 Bullet and the SF-IPTT256A-7D5 Turret Camera, this for the lens with longer range that can be suitable for solar parks.
For all Deep Learning AI camera we recommend using a SD Card in each camera, this is needed so that the camera learn and avoid making mistakes.
The Thermal Specs:
Model | SF-IPTB256A / SF-IPTT256A | |

IRIS Type | Fixed Iris | |
Lens | 3.2mm@F1.1 | 7mm@F1.1 |
Field of View(H×V) | 56°×42.2° | 24.8°×18.7° |
Min. Focusing Distance |
0.5 m | 1.1m |
DRI Distance Human (0.75m) |
Detection: 133m(436ft) Recognition: 33m(108ft) Identification:17m(56ft) |
Detection: 292m(958ft) Recognition: 73m(240ft) Identification:36m(118ft) |
DRI Distance Vehicle (2.3m) |
Detection: 409m (1342ft) Recognition: 102m(335ft) Identification:51m(167ft) |
Detection: 894m(2933ft) Recognition: 224m(735ft) Identification:112m(367ft) |
What to keep in mind to detect or recognize a Human for the 7D5, the Detection is 292m and Recognition 73m of a human that is only 0.75 meter high, so the taller the human, the better that camera can detect a human. Now that we see the more variables we have, the more or less are needed to be used for a project.
The difference between Detection and Recognition.
Detection is the ability to distinguish an object from the background. It involves identifying and localizing objects with bounding boxes, and providing detailed information about their presence and location. At the maximum detection distance, you are able to see that something is there, but you cannot tell what the object is. Recognition is the ability to classify the object class (animal, human, vehicle, boat …). The recognition distance is where you can start to gauge what that something is. Object recognition focuses on categorizing objects without the need for precise localization. Identification is the ability to describe the object in details (a man with a hat, a deer, a Jeep …).
Sample.
When looking at the two images below, we can see a situation from less secure to fully secure.
Explication, to begin, the size of the two fields are different. Using the same SF-IPTT256A-7D5 model camera we need to have 8 SF-IPTT256A-7D5 Thermal camera, Since this is a dual lens camera there are two video streams that can be combined to get an even better image.
When using a Safire Smart NVR and Safire Smart PTZ, and here is a detection there is, the PTZ can be trigger to go to the preprogrammed preset and zoom in on the zone.
Keep in mind that when having 4 SF-IPTT256A-7D5 dual thermal cameras and 1x Safire Smart PTZ we need to have a 16 channel NVR 8 for the thermal cameras and 1 for the PTZ. We recommend using the Safire Smart 8000 B2 NVR.
Then for the second situation a 32 channel recorder, 16 for the thermal camera and 1 for the PTZ camera, for this we recommend using the SF-NVR8432A-B2 Safire Smart NVR.
