When an officer is going to buy a new body worn camera for himself, the following things must be considered necessarily:
Most of body camera support 1080/ 30fps. Some sellers even claim their cameras with 1296P. However, there is no significant difference between these 2 resolutions. In addition, camera with sensor 4MP is better than 2MP. You may see a clear 1080P video and a worse one which is also 1080P resolution, because they are recorded by different sensors. Instead of asking what video resolustion, it would be better to ask sellers what is the sensor and CPU.
Besides body camera, please also consider other cost of accessories. Such as memory card capacity, external camera, PPT cable, multi-dock station and management software. You must weigh all of these factors before deciding the most suitable body worn camera.
Size and weight:
No one is willing to carry a heavy device for a whole day. Especially, there are many additional devices mounted onto officers’ vests. A suitable body camera should not be more than 150 grams and 90mmx60mmx25mm.
Base on 150 grams, the body worn camera should be able to record 10 hours continuously at 720P. After 300-500 cycles, user have to change they battery in order to maintain recording hours.
In some case, body worn cameras have such important evidence. Officer may want to have answers to questions in good time. Remote assistance will be the best solution if you buy the cameras from oversea. Ideally, you can get a 12 month warranty from buyer.
