In our practice of operating video surveillance systems in Siberia and the Far East, we have repeatedly encountered a situation where standard metal casings failed after just 18 months. Corrosion, condensation inside the optics and electronics failure due to overheating in the summer are not theoretical risks, but real losses faced by one of our clients, who lost a quarterly data archive due to depressurization of the case.Polycarbonate housings for outdoor camerassolve this problem radically, providing IP66/IP67 protection at extreme temperatures from -60°C to +80°C without the need for additional heating or air conditioning in 90% of cases.
If you are looking for a reliable solution for perimeter security of industrial facilities, warehouse terminals or transport infrastructure, this article will give you clear selection criteria. We will not use marketing slogans; instead, we will analyze the technical parameters that directly affect the service life of your system, based on GOST standards and real experience in installing more than 5,000 pieces of equipment.
The main advantage of the material lies in its molecular structure, which provides a unique combination of impact resistance and optical transparency. Unlike aluminum, which conducts heat and cold, creating a “thermal bridge” and causing the formation of condensation on the inner surface of the glass, monolithic polycarbonate has low thermal conductivity (0.2 W/m K). This means that the temperature difference between the inside of the case and the outside environment is smoothed out naturally, which is critical for the operation of the IR illuminator and the camera sensor.
The impact strength of polycarbonate is about 80 kJ/m², which is 250 times higher than ordinary glass and 30 times higher than acrylic. In practice, this means that the housing can withstand stones, hail up to 40 mm in diameter and even accidental blows from tools during servicing without cracking. However, there is an important nuance here that suppliers are often silent about: not all brands of polycarbonate are the same. Cheap analogues produced in violation of extrusion technology may have internal stresses that lead to cracking under load after 2-3 years.
We recommend using only virgin polycarbonate with a co-extruded UV filter. This 30-50 micron thick layer is applied during the manufacturing process and protects the material from degradation under solar radiation. Without this coating, polycarbonate turns yellow and becomes brittle after 3-4 years of use in the open sun, especially in southern regions with a high ultraviolet index. You can check the presence of a layer visually at an angle or by requesting a quality certificate from the manufacturer, which indicates the light transmission parameter after 2000 hours of artificial aging according to the ISO 4892-2 standard.
Another critical factor is chemical resistance. Polycarbonate is inert to most aggressive environments found in industrial areas: acid rain, salt fog (important for port cities), oils and technical lubricants. The only weak point of the material is contact with strong alkalis and ammonia, therefore, when installing near chemical plants, it is necessary to take into account the wind rose and the possible release of reagents. In such specific cases, we use additional varnish treatment of the external surface, which increases the product life by another 30-40%.
It is important for design engineers to understand that the use of polycarbonate can reduce the weight of the structure by 40-50% compared to aluminum counterparts of the same strength. This reduces stress on brackets and supports, simplifies installation at height, and reduces foundation requirements for free-standing posts. Savings on metal structures during large-scale deployment of a video surveillance network can reach 15-20% of the total project budget.
Recommendation:When ordering a batch, be sure to request a sample of the material to perform a bend test and check for the presence of a UV layer using a special detector or UV lamp. Don't rely only on paper specifications.
When choosing a protective casing, the key parameter is the degree of protection of the shell, determined by the IEC 60529 standard (in Russia - GOST 14254). For outdoor use, the minimum acceptable level is IP66, but our experience shows that for long-term reliability it is better to focus on IP67 or IP68. The difference between them is not just in numbers, but in fundamentally different scenarios of environmental impact.
The IP66 marking guarantees complete protection against dust and resistance to powerful jets of pressurized water. This is the basic level for cameras installed under building canopies or on walls where direct rainfall is possible, but short-term immersion is excluded. Polycarbonate housings for outdoor cameras with an IP66 rating typically have silicone or EPDM rubber seals that remain flexible over a wide temperature range. It is important to note that the quality of the seal depends not only on the gasket material, but also on the geometry of the groove and the clamping force of the lid.
The IP67 rating adds the ability to be briefly submerged in water up to a depth of 1 meter for 30 minutes. This characteristic becomes critical when structures become icy in winter, when melt water can accumulate in large volumes, or when installed in areas of potential flooding. Housings of this class undergo more stringent tests for the tightness of welds and cable entry points. In our practice, there were cases when cameras with IP66 failed after freezing rain, when water froze in the joints and expanded, breaking the seal, while IP67 models successfully withstood these loads.
The thermal stability of the material allows the equipment to be operated in the range from -60°C to +120°C (short-term). However, the operating temperature of the camera itself is limited by the capabilities of the electronics, usually -40°C...+60°C. The task of the corps is to create a buffer zone. Polycarbonate, having a low coefficient of linear expansion (6.5–7.0 × 10⁻⁵ 1/°C), maintains geometric stability with sudden temperature changes characteristic of a continental climate. This prevents the appearance of microcracks in the places where the brackets are attached and the destruction of adhesive joints.
The optical transparency of polycarbonate reaches 88-90%, which is comparable to optical glass. This is critical for high-resolution cameras (4K and higher), where any distortion or reduction in light transmission affects image detail and license plate recognition range. Unlike matte plastic housings, which scatter light and create flare from the camera's own IR illumination, clear polycarbonate provides a clear optical path. Some models are equipped with an anti-reflective coating, which further reduces reflections from street lights at night.
Product certification must be confirmed by documents of conformity. To work in the market of the Russian Federation and the EAEU, it is mandatory to have a declaration TR CU 004/2011 “On the safety of low-voltage equipment” and TR CU 020/2011 “Electromagnetic compatibility”. In addition, for critical facilities it is recommended to have a fire safety certificate confirming the flammability class of the material (usually V-2 or V-0 for special grades of polycarbonate).
Action:Check the markings on the case with the product passport and make sure that the declared IP class is confirmed by test reports from an accredited laboratory, and not just written on the box.
Vandalism remains one of the main threats to security systems in public places. Polycarbonate housings for outdoor cameras are often marketed as vandal-proof, but the degree of this protection varies. The IK10 standard assumes resistance to impact energy of 20 Joules (5 kg load falling from a height of 40 cm). Monolithic polycarbonate with a thickness of 4-6 mm can easily cope with such a load without splintering, unlike glass or fragile plastic.
However, the strength of the case is determined not only by the wall material, but also by the locking system. We recommend paying attention to hidden fasteners and drill-proof locks. Exposed screws are a weak link that allows an attacker to quickly remove the cover even without damaging the case itself. High-quality models use special bolts with non-standard heads (Torx Security, Tri-wing) and internal fasteners, access to which is possible only after removing the case from the bracket.
Another aspect is protection against unauthorized access to cables. The cable entry must be protected by metal pipes or armored corrugations integrated into the housing. Trying to cut the cable from the outside should not work. In our projects, we often reinforce the lower part of the body with a metal plate, since this is where impacts most often occur when trying to knock down the camera with a stick or stone.
Case geometry also plays a role in protection. Streamlined shapes without protruding elements make it difficult to grip the body with a tool or hands. The absence of flat areas on top prevents the accumulation of snow and ice, which, with its weight, can deform the cover or create pressure on the seals. Condensation ducts should be designed so that water flows downwards without flowing back into the vents.
It is worth mentioning thermal protection. Although polycarbonate itself is a good thermal insulator, in summer, under direct sunlight, the temperature inside a closed black case can reach critical values. Therefore, we strongly recommend choosing light-colored housings (white, light gray), which reflect up to 80% of solar radiation. If the design of the object requires a dark color, it is necessary to provide active cooling or passive radiators on the external surface.
Tip:When installing in areas at high risk of vandalism, use additional steel wire cages over the polycarbonate housing. This will create a double barrier: the cage will take the first blow, and the body will provide a tight seal.
The choice of housing material is often the subject of heated debate between customers and integrators. To make an informed decision, it is necessary to consider the objective advantages and disadvantages of each option in specific operating conditions. Below is a detailed comparison table based on our field tests and manufacturer data.
| Parameter | Polycarbonate (Monolithic) | Aluminum (Cast/Extruded) | ABS plastic / Composites |
|---|---|---|---|
| Impact resistance | High (does not break, bends) | Medium (deforms when hit hard) | Low (cracks in the cold) |
| Thermal conductivity | Low (0.2 W/mK) - no condensation | High (200+ W/mK) - risk of icing | Low |
| Weight | Lightweight (easy to install) | Heavy (requires reinforced brackets) | Very light |
| UV resistance | High (if covered) | Not required (powder coated) | Medium (fades over time) |
| Operating temperature | -60°C … +120°C | -50°C … +80°C (depending on seals) | -40°C … +60°C |
| Price | Medium/High | High | Low |
| Main disadvantage | Resistant to scratches (requires careful washing) | Corrosion in paint chipped areas, condensation | Fragility in the cold, aging |
From the table it is clear thatполикарбонатные корпуса для уличных камерoccupy the niche of optimal balance between cost and reliability. Aluminum casings are indispensable where maximum protection from open flames or extremely high temperatures is required (for example, in metallurgical shops), but for standard outdoor conditions their high thermal conductivity creates more problems than it solves. The need to install heaters in aluminum housings in winter increases the energy consumption of the system by 30-50%, which translates into significant amounts on a city scale.
ABS plastic and cheap composites are only suitable for temporary solutions or installation in mild climates (temperatures below -20°C). In Russian realities, such housings become “disposable”: after the first serious winter, the plastic loses its plasticizers, becomes brittle and crumbles from the slightest wind or vibration. We categorically do not recommend using them at facilities where long-term operation is planned for more than 2 years.
Separately, it is worth mentioning maintainability. Damaged polycarbonate housing can often be restored by hot air welding or gluing with special dichloroethane-based compounds, maintaining tightness. Aluminum requires argon welding and repainting, which is nearly impossible in the field. Plastic cannot be repaired.
In the context of electromagnetic compatibility (EMC), metal has an advantage, creating a Faraday shield. However, modern cameras have their own shielding, and the influence of the external housing on the signal quality is minimal. If the object is located in an area of strong radio interference, you can order polycarbonate cases with an internal coating of a conductive layer, which combines the advantages of a dielectric and the shielding properties of metal.
Conclusion:For 95% of outdoor video surveillance tasks in temperate and cold climates, polycarbonate is the uncontested leader. Select metal only for specific industrial areas with extreme thermal radiation.
Even the highest quality housing will not save the camera if the installation is carried out incorrectly. Service call statistics show that up to 40% of equipment failures are not due to manufacturing defects, but to installer errors. Let's look at the most critical points that you need to pay attention to.
The first and most common mistake is incorrect organization of the cable entry. Often, installers will simply drill a hole in the bottom of the case and run the cable through, using regular electrical tape or silicone caulk to seal it. Over time, the sealant peels off due to thermal expansion, and moisture begins to penetrate inside through the capillaries of the cable. The correct solution is to use special cable glands with rubber cones selected strictly for the cable diameter. The cable inside the housing must have a loop (“drip loop”) so that water flowing down the cable does not reach the entry point, but drips down first.
The second mistake is ignoring ventilation. Many people believe that a sealed enclosure must be completely sealed. This is a misconception. Air circulation is necessary to prevent fogging. Modern polycarbonate cases are equipped with membrane filters (Gore-Tex or analogues) that allow air to pass through but retain water and dust. It is strictly prohibited to seal these holes with foam or paint. If the housing does not have factory ventilation, you will need to install pressure equalization valves at the lower and upper points yourself.
The third problem is mounting the camera inside the case. The use of rigid metal brackets without damping pads leads to the transmission of vibrations from the wind or the operation of the rotation mechanisms directly to the camera matrix. This causes a “jelly” effect on the image and accelerates wear and tear on the mechanical parts of PTZ cameras. We use silicone spacers or rubber washers where the camera contacts the bottom of the case.
Maintenance of polycarbonate also has its own characteristics. The material is resistant to abrasive cleaners and solvents (acetone, gasoline, alcohol in high concentrations), which can cause clouding or microcracks. To clean the exterior surface, use only warm water with neutral soap and a soft microfiber cloth. High pressure washing (Kärcher) is only allowed from a distance of at least 1 meter and at an angle so as not to damage the seals.
Winter operation requires special attention to snow loads. Although polycarbonate is durable, a thick layer of wet snow can put excess pressure on the cover. Regularly clearing snow from the housing roof will extend the life of the seals. Do not use metal scrapers - only soft brushes.
Checklist before handing over the object:Check the tightness of all screws (with force control), make sure that there is a cable drip loop, test the operation of the membrane filters and take a photo report of the condition of the seals.
When purchasing equipment for large projects, unit price is often the deciding factor. Поликарбонатные корпуса стоят дороже аналогов из ABS-пластика и иногда сопоставимы с бюджетными алюминиевыми моделями. Однако расчет полной стоимости владения (TCO) показывает обратную картину.
Рассмотрим пример парка из 100 камер, установленного в регионе с холодной зимой. Использование дешевых пластиковых корпусов приведет к замене 30-40% единиц оборудования уже на третий год из-за разрушения материала. Стоимость замены включает не только новый корпус, но и выезд бригады, подъемную технику, простой системы. В среднем, один выезд сервисной службы стоит от 5000 до 15000 рублей в зависимости от удаленности объекта. Умножьте это на количество отказов, и вы получите сумму, превышающую первоначальную экономию в 3-4 раза.
Использование алюминиевых корпусов без подогрева влечет за собой риски конденсата и обледенения. Добавление нагревательных элементов увеличивает потребление энергии каждой камерой на 20-40 Вт. При круглосуточной работе в течение 6 холодных месяцев (4320 часов) перерасход электроэнергии на 100 камер составит более 30 000 кВт·ч. При тарифе 5 руб./кВт·ч это дополнительные 150 000 рублей расходов ежегодно, которые будут расти с каждым годом.
Поликарбонатные корпуса, благодаря своим теплоизоляционным свойствам, позволяют в большинстве случаев отказаться от активных нагревателей, используя лишь термокомпенсацию самой камеры. Срок службы качественного поли карбонатного корпуса составляет 10-15 лет без потери защитных свойств. Это означает, что капитальные затраты на замену корпусов в горизонте 10 лет будут нулевыми.
Кроме того, следует учитывать фактор гарантии. Производители, уверенные в своем продукте, дают гарантию до 5 лет на поликарбонатные изделия. Это снижает риски для интегратора и повышает привлекательность предложения для заказчика. Надежная система видеонаблюдения — это актив, который работает годами, а не пассив, требующий постоянного ремонта.
Мы проводили аудит проектов, где изначально сэкономили на корпусах. В итоге, через 2 года заказчики потратили на обслуживание и замену в 2.5 раза больше, чем стоила бы изначальная установка премиальных поликарбонатных решений. Экономия должна быть умной, а не сиюминутной.
Recommendation:При составлении сметы закладывайте стоимость поликарбонатных корпусов как инвестицию в надежность, а не как статью расходов. Рассчитывайте бюджет на горизонте 5-7 лет, а не на момент закупки.

Не рискуйте безопасностью вашего объекта, выбирая сомнительные аналоги. Доверьте защиту своей системы профессионалам.
Да, это возможно, но требует соблюдения технологии. Обычные краски плохо держатся на гладкой поверхности поликарбоната и могут содержать растворители, разрушающие материал. Рекомендуется использовать специальные адгезионные грунты для пластиков и акриловые или полиуретановые эмали на водной основе. Перед покраской поверхность необходимо обезжирить изопропиловым спиртом и слегка зашкурить мелкой наждачной бумагой (зернистость 400-600) для улучшения сцепления. Однако помните, что самостоятельная покраска может аннулировать гарантию на УФ-защиту, если будет поврежден заводской слой.
Ни в коем случае не используйте горячую воду — резкий перепад температур может привести к появлению трещин. Не применяйте металлические скребки или ножи. Лучший способ — использовать теплый (не горячий) раствор воды с небольшим количеством соли или специальной незамерзающей жидкостью для стекол, не содержащей аммиака. Нанесите раствор пульверизатором, подождите пару минут, пока лед подтает, и аккуратно удалите остатки мягкой щеткой. Если наледь очень толстая, лучше дождаться естественного оттаивания или использовать фен на минимальной температуре с безопасного расстояния.
Поликарбонат обладает высокой химической стойкостью к кислотам, маслам, жирам и спиртам, но уязвим перед щелочами, аммиаком и некоторыми органическими растворителями (хлорированные углеводороды, ароматические соединения). Если объект находится в зоне действия этих веществ (например, птицефабрики с испарениями аммиака или химические заводы), необходимо провести тест на совместимость или рассмотреть альтернативные материалы, такие как нержавеющая сталь марки 316L или корпуса с фторопластовым покрытием. В сомнительных случаях проконсультируйтесь с нашим техническим отделом для подбора специализированного решения.
При условии использования качественного материала с УФ-защитой и правильной эксплуатации срок службы составляет от 10 до 15 лет. Основные факторы, сокращающие жизнь корпуса — механические повреждения, воздействие агрессивных химикатов и отсутствие регулярного обслуживания (очистки). Желтение и помутнение материала обычно начинаются после 7-8 лет эксплуатации при отсутствии качественного УФ-фильтра.
