What's speed dome camera?
Speed dome cameras also called PTZ dome cameras are widely used in middle and big scale surveillance areas, it can monitor the whole area with just one speed dome camera and without any blind spot. This kind of security cameras always come with vandal-proof housing for protection itself from smash and hit. The zoom module is the crucial component for speed dome cameras. The inside zoom module can pan rotation from 0 degree to 360 degree, and auto flip tilt rotation from 0 degree to 180 degree. Majority of these camera can setup patrol route and cruise points.
Speed dome cameras vary from pan and tilt rotation speed, speed dome cameras can be classified with high speed dome cameras (360 ° per second), middle speed dome cameras (40°-60° per second) and low speed dome cameras (8° - 18 ° per second).
The most important features for speed dome camera is the ability to zoom in and zoom out image, automatically focus image during the operation, and nowadays, majority speed dome cameras are equipped with 10x zoom, 22x zoom, 27x zoom, 36x zoom modules. Typically big zoom module can see more far distance and capture more clear and detailed images.

What's IR speed dome camera ?
IR speed dome camera is the traditional speed dome camera attached with Infrared (IR) illuminators, we call these kind of camera as IR speed dome camera. With help of these IR illuminators, the dome camera can capture images under complete darkness environment, also the night vision distance can reach up much far away (100ft - 400ft).
Some of IR speed dome cameras are equipped with several third generation IR LED array. One single IR LED array is a powerful Infrared illuminator that can emit long range and wide angle active infrared to coverage large area, thus just with several units of IR LED array, the night vision for IR speed dome camera may reach up to 400ft.
The disadvantage of IR speed dome camera is the IR illuminators will generate heat and increase the temperatures during the camera operation. So a good IR speed dome camera with heat ventilation design (fan and heat radiating material) both for IR illuminators and zoom camera module. These design will make the speed dome camera with long operation and stable performance.
Typical features for speed dome camera
- Different types and models of speed dome camera may built-in different zoom camera module, also some speed dome camera may not include with zoom module. Zoom module allows dome camera monitor large area and see more details.
- All speed dome cameras can be controlled via RS485 key board or computer. The camera can automatically & repeatedly scan with high, middle, slow speed in 360 pan rotation, and automatically flip 180 in vertical direction, so the speed dome camera can monitor back scene.
- The PTZ dome camera allow you to store 256 presets which are the key areas to surveillance. Additionally, it allow user arrange these presets in the wanted order and dwell time. This function can make the speed dome camera automatically tour and cruise according to the route and dwell time.
- Equipped with vari-focal auto iris lens, manually and automatically to control the view of field, thus capture images at further away and provided detailed and crisp, clean images.
- 1/3 inch Sony CCD and Effio-E, Effio-S powered zoom module, features with 2D noise reduction, wide dynamic range, high light compensation, motion detection and privacy masking...etc. High quality zoom module can deliver high contrast and true color reproduction images with highest horizontal resolution of 700 tv lines (960H or WD1).
- Majority of speed dome camera with IP66 rated waterproof design, added with internal temperature control, these speed dome camera can work indoor and outdoor.
What's auto tracking speed dome camera ?
Video surveillance are moving to intelligent and smart way. Some new design speed dome cameras with auto tracking function, this function can allow user to set a moving target and the camera will automatically track the moving target, and zoom in, focus in with high speed. Combination with alarm function, the auto tracking speed dome camera can achieve high intelligence surveillance without utilizing software.
