Night Surveillance System Solution

Night Surveillance System Guide

A night surveillance system lets operators find, recognize and locate people and vehicles after dark, when visible-light cameras see little or nothing. JOVSTAR builds these systems from its own thermal imaging, image-intensifier and digital night vision, and laser ranging equipment, with person detection to 3.0 km on handheld thermal binoculars and eye-safe laser ranging with satellite positioning.

Start from the night conditions at your site: how dark it gets, whether there is smoke, haze or vegetation, the distance at which you must notice and recognize a person, and whether observers are on foot, at fixed posts or in vehicles. Then match each task to the technology below.

Ranges are each product’s stated values for its own targets and conditions; night vision recognition figures are for no-moon conditions. See each product page for full specifications.

Choosing the Right Night Technology

No single sensor is best for every night task, which is why a surveillance system combines them.

Thermal imaging: detection in total darkness

Thermal cameras see the heat that people, animals and engines give off, so they need no light at all and see through smoke and light haze. They are the detection layer: the JV-650M detects a person at 3.0 km and a vehicle at 6.5 km. Thermal images show shapes rather than faces or text, and they cannot see through glass or water. See the thermal imaging camera guide.

Image-intensifier night vision: natural detail with no delay

Image-intensifier goggles amplify starlight and sky glow into a sharp, natural image with no screen delay and long battery life: 60–100 hours on one CR123A for the JV-NVM201. They are the best choice for patrols that must walk or drive at night, but they need some ambient light or an infrared illuminator.

Digital low light: recording and color

Digital devices use sensitive CMOS sensors, record photos and video, and can add an 850 nm infrared illuminator for complete darkness. The JV-NVD102 works down to 0.0001 lux; the JV-NVD8X-3.5 shows full-color images down to 0.001 lux on a 3.5-inch screen so several people can view at once.

Thermal fusion: heat and detail in one view

Fusion goggles overlay a thermal image on the night vision view, so a person hiding in shadow stands out while terrain detail stays visible. Person recognition extends from ≥120 m in low-light mode to ≥200 m in fusion mode on the JV-FNV2105 and JV-DNV2105.

Light, Weather and Night Range

Night range depends on the light available, the weather and the task: detecting that someone is there, or recognizing what they are.

• Light level. Night vision figures are quoted for no moon, the hardest case; moonlight and sky glow extend range. Thermal range does not depend on light.
• Weather. Smoke and light haze barely affect thermal imaging, but heavy fog, rain and high humidity shorten both thermal and night vision range.
• Detection vs recognition. Recognition is typically one-third to one-half of detection range: the JV-650M detects a person at 3.0 km and recognizes one at 1.0 km. See detection, recognition and identification ranges.
• Magnification. 1× goggles keep a wide view for moving (recognition 100–120 m); magnified devices such as the JV-NVD104 recognize people at 500 m but narrow the view.

1. Set the decision distance at which operators must notice and recognize a person.
2. Choose thermal detection that covers that distance with margin for rain and humidity.
3. Add night vision or fusion for the teams that move on foot or need detail.
4. Add laser ranging so every detection comes with a distance and position; see how far a laser rangefinder can measure.

Recommended Configurations by Site

Security sites and facilities

Plants, warehouses, campuses and utility sites need patrols that can see in dark corners and between buildings. Patrol teams carry 1× goggles such as the JV-NVB201 or the lighter digital JV-NVD101, with a thermal monocular such as the JV-TSRII350 for open ground. For long fenced perimeters and kilometer-range coverage, see the Border and Perimeter Security System Solution.

Ports and coastlines

Open water and shorelines need long-range detection and distance measurement. A JV-650M or JV-MFB675 binocular at an observation post, paired with a JV-LRFM4 / LRFM8 rangefinder, detects and ranges people and boats; fixed installations can integrate laser modules such as the JV-LRF1508AD (person ranging ≥5,500 m, RS422) with thermal and visible cameras.

Forests and wildlife reserves

Vegetation hides people and animals from the naked eye but not from thermal imaging. Rangers use light handheld thermal devices such as the JV-HTMA213 (115 g) and JV-HTI625 (360 g), and fusion goggles for moving through terrain at night.

Night search and rescue

Search teams find people by body heat in darkness, smoke or undergrowth. The JV-HTM4125 / 4135 monoculars run for 5 hours and charge over USB; four-tube goggles such as the JV-NVF201 give a 100° horizontal view for moving safely, and a JV-LRFM10 gives the casualty’s position to ≤20 m.

Power, Recording and Environment

• Battery life: image-intensifier goggles run 60–100 hours on one CR123A (JV-NVM201); fusion goggles run ≥6 hours on one 18650 cell (JV-DNV2105); plan spare cells for full-night shifts.
• Recording and sharing: the JV-TSRII4 series records to 16 GB of built-in storage, the JV-NVD8X-3.5 records photos and video, and the 5-mode binocular transmits images over Wi-Fi to a command post.
• Environment: the JV-650M and JV-TSRII350 are rated IP66 and the JV-LRFM10 IP67. JOVSTAR tests equipment for high and low temperature, vibration, water and dust protection, and salt spray.
• Eye safety: JOVSTAR 1535 nm rangefinders are Class 1, so they can be used where people may be present.
